Dust pollution of snow cover in the industrial areas of Tomsk city (Western Siberia, Russia)

Assessment of Present-Day Heavy Metals Pollution and Factors Controlling Surface Water Chemistry of Three Western Siberian Sphagnum-Dominated Raised Bogs

“…There are many studies on the accumulation of heavy metals in mires in Europe, Asia and North America, but only a few similar studies for Western Siberia [17,[44][45][46][47][48]. The other studies mainly analysed dust deposition in snow and were carried out in the vicinity of industrial centres [49,50].…”

“…In general, research indicates an increase in the dust-aerosol mass in the air, the volume of which in the troposphere has almost doubled over the past hundred years [51]. Recently the most important sources of heavy metals in the atmosphere within the south-eastern part of Western Siberia have been fires, coal mining, oil and gas production, chemical and petrochemical industries, ferrous and non-ferrous metal smelting and refining, transport, and waste incineration [48,50,[52][53][54][55][56]. The latest research suggests that ferrous and non-ferrous metallurgy is a source of Pb, Cu, Zn and Cd in atmospheric pollution [41,57,58].…”

Variation of trace elements in snow during starting and ending of snowfall in Kyoto city measured by low power total reflection X‐ray fluorescence spectrometry

“…Snowfall has proved to be a vector of deposition for trace‐element input from the atmosphere to ground environment, and the composition of snow is strongly related to air pollution levels. In particular, urban snow contains heavy metals that are transported with snowmelt into the receiving waters . Furthermore, large amounts of road salt are applied before and during snowfall, and this salting also contaminates groundwater and roadside vegetation and damages soil structure .…”

“…In particular, urban snow contains heavy metals that are transported with snowmelt into the receiving waters. [7,8] Furthermore, large amounts of road salt are applied before and during snowfall, and this salting also contaminates groundwater and roadside vegetation and damages soil structure. [9,10] The WHO Guidelines for drinking-water quality [11] confirm that concentrations in excess of about 250 mg/L of chloride in drinking water can give rise to a detectable taste in water.…”

“…Total reflection X‐ray fluorescence (TXRF) analysis in the environmental field has improved greatly, and atmospheric pollution studies of different kinds of samples such as dust and heavy metals in urban snow, road‐salt and contamination in snowmelt, and rainwater have been reported by TXRF.…”
