Appendix 4.4.1: Air Monitoring Methodology
Methods of Air Quality Measurement
on the Boundary of the Bakyrchik Mine Sanitary Protection Zone
For determination of the air quality on the boundary of the Bakyrchik Mine sanitary
protection zone, tool measurements of the following components are made: dust, ar-
senic (inorganic connections), nitrogen (IV) dioxide, sulphur dioxide, carbon oxide.
Measurements are taken by means of the following devices and the equipment:
─
arsenic, inorganic compounds — Migunov's aspirator M-852, the allonge
with a suport grid, rubber hoses, AFA-VP-10 (AFA-VP-20) filter, photo-electric
calorimeter KFK-2;
─
nitrogen (IV) dioxide — а Migunov's spirator of M-852, absorbing vessel of
Zaytsev filled in laboratory with the corresponding absorbing solution, a calo-
rimeter photo-electric KFK-2;
─
sulfur dioxide — Migunov's aspirator of M-852, absorbing vessel of Zaytsev
filled in laboratory with the corresponding absorbing solution, a calorimeter
photo-electric KFK-2;
─
carbon oxide — indicator tube, airintake (mechanical aspirator of AM-5),
rubber hoses;
─
dust — Migunov's aspirator of M-852, the allonge with a basic grid, rubber
hoses, the AFA-VP-10 filter.
Instrumental measurements are conducted in accordance with norm and methodolo-
gies existing in the RoK, including:
─
dust — GOST 17.2.4.05–83. Nature protection. Atmosphere. Gravimetric
method of dust suspended substances determination;
─
arsenic, inorganic compounds — RD 52.04.186-89 Guidelines for the Control
of air pollution. - M .: Gidrometeoizdat, 1991. Photometric method;
─
nitrogen (IV) dioxide — RD 52.04.186-89 Guidelines for the Control of air pol-
lution. - M .: Gidrometeoizdat, 1991. Photometric method;
─
sulfur dioxide — RD 52.04.186-89 Guidelines for the Control of air pollution. -
M .: Gidrometeoizdat, 1991. Photometric method;
─
carbon oxide — GOST 12.1.014-84 *. SSBT. Method of measuring the concen-
tration of harmful substances by detector tubes.
Measurements procedure is described below:
─
Dust — air sampling to determine average daily concentration of dust is con-
ducted continuously during 24 hours (in case of high dust content - by 20 min
cycles with equal intervals) with specific consumption of 5dm3 (min x cm2). To
determine one-time concentration sampling is conducted during 20 minutes.
Maximal dust capability of filter made of special fabric is 5mg/cm2. Filter with
preliminary achieved fixed mass and its ID on is put by forceps into the filter
holder fixed thoroughly with a ring and cap screw. Filters are carefully folded in
half or in four with exposed surface inside and then put into tracing paper and
plastic bag. Total volume of filtered air is determined upon completion of sam-
pling. Exposed filter is taken out of the bag, put into a glass cup and incubated
during 1 hour in the weighing room. If sample was taken at relative air humidity
close to 100% the filter mass was increased to fixed mass. For this purpose the
filter in a glass cup was put into an exsiceator with melted calcium chloride for 2
hours or drying oven with temperature from 40 °С to 50 °С for 30-50 minutes
and then incubated for 30-50 minutes in weighing room. If the weighing
shows change of the filter's mass drying is repeated. Mass of filter with dust
is determined by means of weighing.
─
Arsenic, inorganic compounds — air is sampled by the methodology similar
to the methodology of sampling for dust content. Filter with sample is put in-
to a glass and poured over by 8mm of 12% aqua ammonia solution and 1ml
of 10% hydrogen peroxide and incubated during 10 minutes being stirred by
a glass stick. Then the solution is poured into porcelain cup and the filter is
washed several times by small portions (2-3ml) of aqua ammonia solution.
Every time it is thoroughly pressed off by a glass stick. Wipes are combined
with the sample and boiled dry in water bath, dry residue is then dissolved in
2ml of water. Solution is filtered through a small filter into a 5ml volumetric
tube. The cup is washed twice by 1.5ml of water and wipes are filtered
through the same filter and total volume of liquid in the tube is increased to
5ml. Then 0.5ml of ammonium molybdate solution and 0.2ml of hydrazine
sulphate are added into the tube. The content is then thoroughly shaken and
heated up in water bath during 10-15min. After cooling to indoor tempera-
ture the optical density of the solution is determined. Measurements are
conducted in 10mm wide cuvets providing wave length of 840nm using pho-
toelectric calorimeter. Before the analysis optical density of neutral sample is
measured. For this purpose clean filter is put into a glass, poured over by 8ml
of 12% of ammonia solution and analyzed by similar method. Arsenic content
in the sample is determined using calibration plot by difference of sample so-
lution and neutral solution optical density measurements results.
─
Nitrogen (IV) dioxide — Aspirator M-852 blows air sample through two se-
ries-connected absorption vessels with 10ml of 8% solution of potassium io-
dide in each during 20 minutes with 0.2-0.3l/min velocity. Then either 1ml or
5ml of solution from each vessel are put into calorimetric test-glass, added
with 8% solution of potassium iodide to 5ml volume and then diluted with
1ml of Griess reagent and mixed. In 20 minutes 0.01 weak solution of sodium
sulphite is added by 0.5 ml; the resulting solution is mixed and scanned pho-
tometrically in cuvet providing 1cm thickness of layer and wave length of
520nm in comparison with control solution simultaneously prepared by the
analogous methodology. Content of nitrogen (IV) dioxide is measured by pre-
liminary generated calibration plot.
─
Sulphur dioxide — Aspirator M-852 blows air sample through absorption ves-
sel with porous plate containing 6 ml of absorbing solution during 30 minutes
with 1-2l/min velocity. 5ml of solution sample from absorption vessel are put
into calorimetric test-glass, diluted with 1ml of barium chloride solution,
mixed and then in ten minutes scanned photometrically in cuvet providing
1cm thickness of layer and wave length of 410nm in comparison with control
solution simultaneously prepared by the analogous methodology. Content of
sulphur dioxide in analysed volume is measured by preliminary generated cal-
ibration plot.
─
Carbon oxide — air intake device has a detector pipe attached which is de-
signed to measure the concentration of harmful substances. Measured vol-
ume of air sample was blown through the detector pipe. Then air was sam-
pled via 3 pipes. Concentration of carbon oxide was measured by the length
of detecting powder colour change in the pipe (linear-coloristic detector
pipe). The result of measurement is arithmetic average of the results of series
of observations. If the contours of the of original and reacted powder layers’
colours are blurred concentration of the harmful substances in interest is
measured by the scale put along the upper and lower parts of the contour.
Average values of the measurement is accepted as the result.
Location of air quality sampling points is adjusted depending on the wind direction.
Georeferencing on the site plan is undertaken at the moment of sampling. All instru-
mental measurements of air quality on the boundary of the Bakyrchik mine’s are con-
ducted on single occasion being accompanied by meteorological observations. Number
of individual measurements per point is 3. Air is sampled in not less than 3 days after
precipitation.
