Remarks:
(1)
For 1-hour and 24-hour TSP & 24-hour RSP (Ambient Arsenic) monitoring, monitoring stations that are specifically
within the 500m buffer area projected from the site boundary of works
contract(s) will be considered being the representative monitoring stations for
the corresponding works contract(s) and the associated impact monitoring
exercises will be kicked off once the nearest works contracts have been
commenced and undertaken during the reporting period/month.
For Noise
Monitoring, monitoring stations that are specifically within the 300m buffer
area projected from the site boundary of works contract(s) will be considered
being the representative monitoring stations for the corresponding works
contract(s) and the associated impact monitoring exercises will be kicked off
once the nearest works contracts have been commenced and undertaken during the
reporting period/month.

Remarks:
(1) KTN-DMS4(B) is the
alternative air monitoring stations proposed to replace KTN-DMS4.
(2) As KTN-DMS4 - Temporary structure near Fanling
Highway (near Pak Shek Au) is no longer as existing ASR, air quality monitoring
station should be relocated to the alternative dust monitoring location
according to the updated EM&A Manual, Section 2.6.2. According to Figure
3.1 of Approved EIA report and site visits conducted in June 2022, ASR at near
KTN-E70 Temporary Structure near Fanling Highway near Pak Shek Au is
considered as the most representative alternative station KTN-DMS4(B) for air
quality monitoring for KTN-DMS4 (i.e. KTN-E162).
(3) Impact monitoring will be
carried out when the planned sensitive receivers are commissioned.
2.3.1 In
accordance with the requirements for placement of equipment, as set out of the
EM&A Manual of the Project, the approved updated EM&A Manual for the
First Phase, the monitoring parameter, frequency and duration of impact air
quality monitoring are listed in Table 2.2.

during the reporting period.
2.4.1 Direct reading dust meters and
High-Volume TSP Samplers were used for measuring the impact air quality
monitoring (i.e. 1-hour TSP and 24-hour TSP) during the reporting period in
accordance with the Service Contract No. NDO 04/2019 Monthly EM&A Report.
According to Section 2.4.5 of the EM&A Manual, the approved updated
EM&A Manual for First Phase ET, the proposed use of direct reading dust
meter was submitted to and agreed by the First Phase IEC. HVS for 24-hour TSP
monitoring will be adopted once secured supply of electricity become available
at FLN-DMS5(A) and KTN-DMS4(B).
2.4.2 Table 2.3 summarizes the equipment used in the air quality
monitoring programme. Copies of the calibration certificates for air quality

and accuracy of the results measured by direct reading method at 2-month
intervals throughout all stages of the air quality monitoring.
Instrumentation
(TISCH Model: TE-5170 / TE-5170X)
2.5.4 The following guidelines were
adopted during the installation of HVS:
·
A horizontal
platform with appropriate support was provided to secure the samplers against
gusty wind. the dust meter at least 1.3 meters above ground;
·
No two samplers
were placed less than 2 metres apart.
·
The distance
between the sampler and an obstacle, such as buildings, was at least twice the
height that the obstacle protrudes above the sampler.
·
A minimum of 2
metres of separation from walls, parapets and penthouses was required for
rooftop samples.
·
A minimum of 2
metres separation from any supporting structure, measured horizontally was
required.
·
No furnaces or
incineration flues were nearby.
·
Airflow around
the sampler was unrestricted.
·
The sampler were
more than 20 metres from the drip line.
·
Any wire fence
and gate, to protect the sampler, should not cause any obstruction during
monitoring.
·
Permission and
access to monitoring stations have been obtained to set up the samplers.
·
A secured supply
of electricity was provided to operate the samplers.
Filters
Preparation
2.5.5 Wellab Limited (HOKLAS Registration No. HOKLAS083) is a
HOKLAS accredited laboratory and responsible for the preparation of 24-hour
conditioned and pre-weighed filter papers for the monitoring team.
2.5.6 All filters were equilibrated in the conditioning
environment for 24 hours before weighing. The conditioning environment
temperature was around 25°C and not variable by more than ±3°C; the relative
humidity (RH) was < 50% and not variable by more than ±5%. A convenient
working RH was 40%.
Operating/Analytical Procedures
2.5.7 Operating/analytical procedures for the air quality
monitoring were highlighted as follows:
·
Prior to the
commencement of dust sampling, the flow rate of the HVS was properly set
(between 1.1 m3 /min. and 1.4 m3 /min.) in accordance
with the manufacturer's instruction to within the range recommended in USEPA
Standard Title 40, CFR Part 50;
·
The power supply
was checked to ensure the sampler worked properly;
·
On sampling, the
sampler was operated for 5 minutes to establish thermal equilibrium before
placing any filter media at the designated air quality monitoring station;
·
The filter
holding frame was then removed by loosening the four nuts and carefully a
weighted and conditioned filter was centered with the stamped number upwards,
on a supporting screen;
·
The filter was
aligned on the screen so that the gasket formed an airtight seal on the outer
edges of the filter. The filter holding frame was then tightened to the filter
holder with swing bolts. The applied pressure should be sufficient to avoid air
leakage at the edges;
·
The shelter lid
was closed and secured with the aluminium strip;
·
The timer was
then programmed. Information was recorded on the record sheet, which included
the starting time, the weather condition and the filter number (the initial
weight of the filter paper can be found out by using the filter number);
·
After sampling,
the filter was removed and kept in a clean and tightly sealed plastic bag. The
filter paper was then returned to the HOKLAS accredited laboratory (Wellab
Ltd.) for reconditioning in the humidity-controlled chamber followed by
accurate weighting by an electronic balance with a readout down to 0.1mg. The
elapsed time was also recorded; and
·
Before weighing,
all filters were equilibrated in a conditioning environment for 24 hours. The
conditioning environment temperature should be between 25°C and 30°C and did
not vary by more than ±3°C; the RH should be < 50% and did not vary by more
than ±5%. A convenient working RH is 40%. Weighing results were returned for
further analysis of TSP concentrations collected by each filter
Maintenance/Calibration
2.5.8
The following maintenance/calibration
was required for the HVS:
· The high-volume motors
and their accessories were properly maintained. Appropriate maintenance such as
routine motor brushes replacement and electrical wiring checking were made to
ensure that the equipment and necessary power supply are in good working
conditions; and
· All HVS were calibrated
(five point calibration) using Calibration Kit prior to the commencement of
baseline monitoring and thereafter at bi-monthly intervals.
Instrumentation
(Sibata Model: LD-5R)
2.5.9 The measuring procedures of the dust meters were in
accordance with the Manufacturers Instruction Manual as follows:
· Placed the dust meters at
least 1.3m above ground
· Set POWER to ON and
make sure that the battery level not flashed or in low level;
· Pulled the air sampling
inlet cover up;
· Pushed the knob at
MEASURE position;
· Set time/mode setting to
[BG] by pushing the time setting switch. Then, started the background
measurement by pushing the start/stop switch once. It took 6 sec. to complete
the background measurement;
· Turned knob to SENSI. ADJ
position and pressed in;
· Pushed Start/Stop switch
once;
· Gently returned knob to
the MEASURE position;
· Pushed the time setting
switch to change the time setting display to [LOG] at the bottom left of the
liquid crystal display;
· Removed the cap and
started measurement; and
· Information such as
sampling date, time, count value and site condition were recorded during the
monitoring period.
Maintenance/Calibration
2.5.10
The following maintenance/calibration
was required for the direct reading dust meter:
· Direct reading dust meter
shall be used in determining 1-hour TSP and 24-hour TSP at air quality
monitoring points. The direct reading dust meters have been calibrated against
high volume samplers (HVSs) bi-monthly. A 2-day, three 3-hour measurement
results per day from direct reading dust meters were taken to compare with the
sampling results from the HVSs. The correlation between the direct reading dust
meters and the HVSs were then concluded. By accounting for the correlation
factor, the direct reading dust meters are considered to achieve comparable
results as that of the HVSs.
· The HVS used to calibrate
the direct dust monitor will need to be calibrated bi-monthly. Details of
maintenance and calibration for the HVS refers to Section 2.5.8.
Calibration for the air quality monitoring equipment is attached to the Appendix
2.2.

3.4.1 As
referred to the technical memorandum issued under the Noise Control Ordinance
(NCO), sound level meters in compliance with the International Electrotechnical
Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1)
specifications were used for carrying out the construction noise monitoring.
3.4.2 Noise
measurements were not made in fog, rain, wind with a steady speed exceeding 5
m/s or wind with gusts exceeding 10 m/s. The wind speed was checked with a
portable wind speed meter capable of measuring the wind speed in m/s.
3.4.3
Sufficient numbers of noise
measuring equipment and associated instrumentation were prepared by the ET. All
the equipment and associated instrumentation were clearly labelled.
3.4.4 The
monitoring procedures are as follows:
·
For faηade
measurement, the monitoring station was set at a point 1 m from the exterior of
the sensitive receivers building faηade and set at a position 1.2 m above the
ground. For free-field measurement, the monitoring station was set at a
position 1.2 m above the ground.
·
The battery
condition was checked to ensure good functioning of the meter.
·
Parameters such
as frequency weighting, the time weighting and the interval were set as
follows:
-
Frequency weighting: A
-
Time weighting: Fast
-
Interval: 30 minutes (Leq(30mins))
·
Prior to and
after each noise measurement, the meter was calibrated using an acoustic
calibrator for 94.0 dB at 1000 Hz. If
the difference in the calibration level before and after measurement is more
than 1.0 dB, the measurement was considered invalid and repeat of noise
measurement will be required after re-calibration or repair the equipment.
·
At the end of
the monitoring period, the values of Leq, L10 and L90
were recorded. In addition, noise
sources were recorded on a standard record sheet.

Ecology
6.1.1 This
section was derived from the ecological monitoring conducted during the
construction phase by the Remaining Phase ET, supplemented with findings
retrieved from the First Phase ET under Service Contract No. NDO 04/2019
Environmental Team for Environmental Monitoring and Audit Works in Construction
Phase for the First Phase Development of Kwu Tung North and Fanling North New
Development Areas. This approach was undertaken to prevent redundancy in survey
efforts.
Weekly Site Inspection
6.2.1 Weekly site inspections by the ET from the First
Phase of the KTN/FLN NDAs Project for ecological mitigation measures are
conducted as part of the overall weekly environmental site inspections. These
inspections audit the ecological mitigation measures implemented within the
active works area to ensure that the activities do not significantly impact the
ecologically sensitive receivers in the active works areas.
Monitoring of Measures to Minimise Disturbance to Water Birds in Ng
Tung River, Sheung Yue River, Shek Sheung River and Long Valley
6.2.2 As stipulated in Section 12.3.2.5 of the Updated
EM&A Manual, if development under the NDAs project occurs within 200m of
Sheung Yue River, Ng Tung River, Shek Sheung River and Long Valley, weekly
transect monitoring at high and low tides (above/below 1.5m at Tsim Bei Tsui
Station) should be conducted. The monitoring aims to identify and count bird
species in the river channels and Long Valley Nature Park (LVNP) and detect any
disturbances from construction activities, following the methodology in Table
12.1 of the Updated EM&A Manual. Monitoring in Long Valley should follow
the Hong Kong Bird Watching Society (HKBWS) bird monitoring programme's
methodology for comparable and comprehensive results.
Monitoring of Measures to Minimise Impacts to Ma Tso Lung Stream and
Siu Hang San Tsuen Stream, and Long Valley
6.2.3 As stipulated in Section 12.3.2.14 of the Updated
EM&A Manual, aquatic fauna monitoring should be conducted monthly during
the wet season (April October) of the construction phase.
Monitoring of Measures to Minimise Impacts on Ecological Sensitive
Habitats from Disturbance and Pollution
6.2.4 As stipulated in Section 12.3.2.17 of the Updated
EM&A Manual, measures to minimize impacts should be monitored during the
construction phase. The purpose of these surveys is to assess the effectiveness
of measures aimed at reducing disturbances and pollution in ecologically
sensitive habitats through standard fauna transect surveys.

Monitoring of Measures to Minimise Disturbance to Water Birds in Ng
Tung River, Sheung Yue River, Shek Sheung River and Long Valley
Monitoring Methodology
6.3.1 Birds identified by their calls but not visually
located were recorded as "heard", while those observed flying over
the survey area were noted as "in flight." Species of conservation
importance were also specified. Additional information at the time of the
survey, such as weather conditions, tidal conditions, tide levels, and
noticeable natural or anthropogenic activities, were documented. For the
avifauna survey, ornithological nomenclature referenced The Avifauna of Hong Kong (Carey
et al., 2001), The Birds of Hong
Kong and South China (Viney et al., 2005), and the most recent
updated lists from other sources (e.g., Hong Kong Bird Watching Society).
Monitoring
Parameters
6.3.2 The monitoring parameters are as follows:
·
Abundance of
birds;
·
Types of
habitats utilized by birds; and
·
Notable bird
behaviours such as roosting, feeding, nesting and presence of juveniles.
Monitoring Location
6.3.3 For this reporting month, First Phase ET conducted
avifauna monitoring at Ng Tung River, Sheung Yue River, and Long Valley, while
the Remaining Phase ET conducted avifauna monitoring at Shek Sheung River.
Relevant transect routes are summarized in Table 6.2 and illustrated in Figure 6.1 and Figure 6.2. As the sensitive
receivers are large waterbirds and are easily visible, the transect routes only
needed to follow one riverbank.

6.3.15 As stipulated in Section 12.3.2.14 of the Updated
EM&A Manual, aquatic fauna monitoring should be conducted monthly during
the wet season of the construction phase. Therefore, no aquatic fauna
monitoring was carried out during the reporting month. Monitoring activities
will be resumed in April 2026.
Monitoring of
Measures to Minimise Impacts on Ecological Sensitive Habitats from Disturbance
and Pollution
Monitoring Methodology
Terrestrial Mammal
6.3.16
Mammal
surveys were conducted both during the day and at night along transect routes
that may be potentially utilized by terrestrial mammals. Observations included
field signs such as droppings, footprints, diggings, and burrows left by larger
terrestrial mammals. Any mammals directly observed were recorded, and
identification was as accurate as possible based on the field signs.
6.3.17
Bat
surveys were conducted along the transect routes shortly after sunset using a
bat detector to record echolocation calls. The relative abundance of the
species encountered were estimated with reference to the baseline monitoring
results, using a scale from one (species recorded within transect routes) to
three (dominant species within transect routes), for comparison between
baseline and current monitoring results. Mammal nomenclature followed Shek
(2006).
6.3.18 Echolocation calls of bats were recorded using a bat
detector, which listed possible bat species with similar call patterns and
frequencies. The structure of the recorded echolocation calls was later
analysed to identify species as accurately as possible. Due to the lack of
literature on echolocation call structures, field identification of some bat
species in Hong Kong is challenging, and some species could only be identified
to the genus level or remain unidentified from the recordings.
6.3.19 Identification of bat species encountered in the
surveys was made by considering the possible species suggested by the bat
detector, their distribution in Hong Kong, previous records in the EIA Report
and Baseline Monitoring Report, and the structure of the echolocation calls
(including call structure, frequency, duration, and inter-pulse interval) with
reference to relevant literature.
Herpetofauna (Amphibians and Reptiles)
6.3.20 Both daytime and nighttime amphibian surveys were
conducted whenever possible following or during periods of rainfall, focusing
on areas suitable for amphibians (e.g., forests, shrublands, grasslands,
streams, ponds, marshes, etc.). Calling amphibians were recorded, supplemented
by visual observations of eggs, tadpoles, adult frogs, and toads.
6.3.21 Active searches of appropriate microhabitats, such
as stones, pond bunds, crevices, and leaf debris, was primarily conducted.
Observations of exposed, basking, and foraging reptiles were also carried out.
Nomenclature for amphibians and reptiles followed Chan et al. (2005) and Karsen
et al. (1998), respectively.
Butterfly and Odonates
6.3.22 Butterflies and dragonflies observed along the
transects were identified and counted. Special attention was given to their
preferred habitats, such as watercourses, fishponds, and vegetated areas.
Nomenclature and protection status of the species followed Lo et al. (2005) for
butterflies and Tam et al. (2011) for dragonflies.
Monitoring Parameters
6.3.23 The monitoring parameters are as follows:
·
Species
composition;
·
Abundance;
·
Distribution for
fauna observed; and
·
Species of
conservation importance would be specified.
Monitoring Location
6.3.24 According to the Updated EM&A Manual, the
transect routes for monitoring of ecologically sensitive receivers should
follow the following:

Remarks:
(1)
Number of species (species richness) recorded; the
results in the reporting month for terrestrial mammals, herpetofauna and
odonates are calculated based on the number of native species recorded along
the transects.
(2)
Exceedance of Action Level occurs when the
monitoring result is lower than the Action Level.
(3)
Exceedance of Limit Level occurs when the
monitoring result is lower than the Limit Level.
6.3.32 2 Action Level exceedances (Odonates for Transect T1
and Transect T6) and 1 Limit Level exceedance (Odonates for Transect T3) were
recorded for Monitoring of Measures to Minimise Impacts on Ecological Sensitive
Habitats from Disturbance and Pollution during the reporting month. All
exceedances were considered non-project related, as no evidence suggested the
exceedances were associated with project activities. Additionally, the low
species diversity of odonate species were impacted by a shift from prolonged dry
conditions to brief, intense rainfall, despite the favourable weather condition
recorded throughout the reporting month. Heavy showers occurred early in the
month had altered the water levels and turbidity, which might have disrupted
odonate breeding habitats and suppressed flight activities, and eventually
influenced the survey findings. As a result, the low species diversity observed
across survey transects reflected the effects of such short-term environmental
fluctuations rather than representing a long-term decline in habitat
quality.
Details of the Influencing
Factors
6.3.33 The
details of the influencing factors were adopted from the observations of the
First Phase ET. During the monitoring of measures to minimize disturbance to
waterbirds in Long Valley and Sheung Yue River, anthropogenic activities such
as excavation and other construction activities were observed near Long Valley.
It should also be noted that the Long
Valley Nature Park has been opened to the public since 09 November 2024. Potential
increase in people visiting the park may potentially impact the habitats in
Long Valley and cause disturbances to the bird communities in this area. Construction
works were also observed along Sheung Yue Riverr.
6.3.34 During
the monitoring of measures to minimize disturbance to waterbirds in Ng Tung
River, various anthropogenic activities were observed, such as construction
works along Transect T2, recreational use of remote-control boats and toy helicopters in
both Transects T1 and T2, and recreational fishing along these two transects.
Survey Summary
6.3.35 All
ecological monitoring surveys for the reporting month have been carried out as
scheduled, with 2 exceedances in Action Levels and 1 exceedance
in Limit Level were reported for odonate species during the non-aquatic fauna
surveys conducted by the First Phase ET. All exceedances were considered as
non-project related.
6.4
Man Kam To Egretry Monitoring
6.4.1
A pre-site clearance check of the Man Kam To Egretry
(MKT Egretry) was undertaken on 13 February 2026 to investigate its status,
extent, and location prior to the commencement of works within 100m of the
egretry, pursuant to EM&A Manual Section 14.3.2.3.
6.4.2
Egretry location was checked on 31 March 2026 for the
reporting month to identify and confirm the presence of any ardeid nests,
covering the previous core extent and its split colonies, prior to the
commencement of works activity within 100m of the egretry.
6.4.3
Egretry monitoring for the MKT Egretry and its split
colonies will be conducted once in April 2026.
6.5.1 Should
non-compliance of the ecological monitoring criteria occur, actions in
accordance with the Event and Action Plan in Appendix 6.4 shall be carried out.
7
Landscape and Visual
7.1.1
According to the approved EM&A
manual and Updated EM&A Manual for the First Phase, site audits should be
undertaken at least once every two weeks during the construction
period, by the Environmental Team. Particularly, to check that the proposed
landscape and visual mitigation measures are properly implemented and
maintained as per their intended objectives. Mitigation measures recommended in
the EIA Report as the audit requirements including, preservation of existing
vegetation, transplanting of affected trees, compensatory tree planting,
control of night-time lighting glare, erection of decorative screen hoarding
and management of construction activities and facilities.
7.2.1 Bi-weekly
landscape and visual site audits were carried out by the ET during the
reporting period. Inspections were carried out on 3 and 19 March 2026 for
ND/2024/01, 3 and 19 March 2026 for
ND/2024/02, 2, 20 and 30 March 2026 for ND/2024/03, 13 and 24 March 2026 for
ND/2024/04, and 23 March 2026 for ND/2024/06, 12 and 26 March 2026 for
ND/2024/07. No particular observation
was recorded in this reporting period.
7.3.1 Should
any non-compliance of the criteria occur, action in accordance with the Event
and Action Plan in Appendix 7.1 shall be followed.
8.1.1 According
to the approved EM&A Manual and Updated EM&A Manual for the First Phase,
an ambient arsenic monitoring is required to be conducted in KTN during the
clean-up processes of arsenic containing soil and the construction phase.
8.1.2 The
RSP concentration was measured by HVS equipped with PM10 selector (PM10 HVS)
following the "Reference Method for the Determination of Particulate
Matter as PM10 in the Atmosphere" Part 50 Chapter 1 Appendix J, Title 40
of the Code of Federal Regulations of the USEPA.
8.1.3 The
Dust-laden air was drawn through PM10 HVS fitted with a conditioned
pre-weighting filter paper, at a controlled rate. After sampling for 24-hour,
the filter paper with retained PM10 particulates was collected and returned to
the laboratory for drying in a desiccator followed by accurate weighting.
24-hour average RSP levels were calculated from the ratio of the mass of PM10
particulates retained on the filter paper to the total volume of air sampled.
8.1.4 The
weighted filter paper was prepared for arsenic testing through a "Hot Acid
Extraction Procedure". The extracted material was tested for arsenic by
using Inductively Coupled Plasma/Mass Spectrometry (ICP/MS). The extraction and
testing were referenced to the following methods:

Instrumentation
8.5.1 HVS
(GMW PM10 (TE6070X)) complete with appropriate sampling inlets was employed for
24-hour RSP monitoring. The sampler was composed of a motor, a filter holder, a
flow controller and a sampling inlet and its performance specification complied
with that required by USEPA Standard Title 40, Code of Federation Regulations
Chapter 1 (Part 50).
8.5.2 The
following guidelines were adopted during the installation of HVS:
·
a horizontal
platform with appropriate support to secure the samplers against gusty wind was
provided;
·
no two samplers
were placed less than 2 meters apart;
·
the distance
between the sampler and an obstacle, such as buildings, was at least twice the
height that the obstacle protrudes above the sampler;
·
a minimum of 2
meters of separation from walls, parapets and penthouses was required for
rooftop samplers;
·
a minimum of 2
meters separation from any supporting structure, measured horizontally was
required;
·
no furnace or
incinerator flue was nearby;
·
airflow around
the sampler was unrestricted;
·
the sampler was
more than 20 meters from the dripline;
·
any wire fence
and gate, to protect the sampler, were not cause any obstruction during
monitoring;
·
permission was
obtained to set up the samplers and to obtain access to the monitoring
stations; and
·
a secured supply
of electricity was needed to operate the samplers
Operating/analytical
procedures for the operation of HVS
·
Prior to the commencement of
the dust sampling, the flow rate of the high volume sampler was properly set
(between 1.1 m3 /min. and 1.4 m3 /min.) in accordance
with the manufacturer's instruction to within the range recommended in USEPA
Standard Title 40, CFR Part 50;
·
The power supply was checked to
ensure the sampler worked properly. On sampling, the sampler was operated for 5
minutes to establish thermal equilibrium before placing any filter media at the
designated air monitoring station;
·
The filter holding frame was
then removed by loosening the four nuts and a weighted and conditioned filter
was carefully centered with the stamped number upwards, on a supporting screen;
·
The filter was
aligned on the screen so that the gasket formed an airtight seal on the outer
edges of the filter. The filter holding frame was then tightened to the filter
holder with swing bolts. The applied pressure was sufficient to avoid air
leakage at the edges;
·
The shelter lid
was closed and secured with the aluminium strip;
·
The timer was
then programmed. Information was recorded on the record sheet, which included
the starting time, the weather condition and the filter number (the initial
weight of the filter paper can be found out by using the filter number);
·
After sampling,
the filter was removed and sent to the Wellab Ltd. for weighing. The elapsed
time was also recorded; and
·
Before weighing,
all filters were equilibrated in a conditioning environment for 24 hours. The
conditioning environment temperature was between 25°C and 30°C and did not vary
by more than ±3°C; the relative humidity (RH) was < 50% and did not vary by more
than ±5%. A convenient working RH was 40%. Weighing results were further
analysis of RSP concentrations collected by each filter.
8.6.1 The
following maintenance/calibration was required for the HVS:
·
The high volume
motors and their accessories were properly maintained. Appropriate maintenance
such as routine motor brushes replacement and electrical wiring checking were
made to ensure that the equipment and necessary power supply were in good
working condition; and
·
High volume
samplers were calibrated at bi-monthly intervals using TE-5025A Calibration Kit
throughout all stages of the ambient arsenic monitoring.
8.7.1 Quartz
filters of size 8 x 10 were labelled before sampling. A HOKLAS accredited
laboratory, Wellab Ltd., was responsible for the preparation of 24-hour
conditioned and pre-weighed filter papers for the monitoring team. The balance
for weighting filter paper was regularly calibrated against a traceable
standard.
8.7.2 All
filters, which were prepared and equilibrated in the conditioning environment
for 24 hours before weighing. The conditioning environment temperature was
around 25 °C and not variable by more than ±3 °C; the relative humidity (RH)
was < 50% and not variable by more than ±5%. A convenient working RH was
40%.
8.7.3 Wellab
Ltd. (HOKLAS Registration No. HOKLAS083), was responsible for the extraction
and testing procedure for Arsenic and comprehensive quality assurance and
quality control programmes were conducted.
