SNOW INDICATION AS INDEX OF ENVIRONMENTAL POLLUTION OF BILA TSERKVA BY TRAFFIC EMISIONS
The cars were counted in different streets of Bila Tserkva. The transport was divided into the categories depending on carrying capacity and fuel using. It was set that passenger cars mostly passed along the blvd. 50-richa Peremogy and Skvyrske shosse. Also it should be noted that at the 3 and the 4 observation points it was the smallest number of heavy trucks - 9 and 4 % of its total number. The largest number of cars were observed at point 5, that is on the blvd. 50-richa Peremogy. A snow indication was carried out to determine the pollution of the city depending on the distribution of traffic in the streets. pH, transparency, smell of the melted snow and traffic intensity were determined. Also it was defined the dust load. pH in snow water ranged from 7,30 to 6,00. This is due to the pollution of snow cover by the products of fuel combustion such as sulfur oxides, nitrogen and carbon. It was observed more alkaline value of рН at 1 m distance from the road. In Skvyrske shosse and the blvd. 50-richa Peremogy it was the least transparency near the road that testifies to sediment pollution from traffic. On the blvd. 50-richa Peremogy the water was turbid even at remote from the roadway. The area of Geroiv Chornobylia Str. was the cleanest on this indicator - the height of water in the cylinder was 31, 38 and 40 cm on looking at the font. All samples had insignificant intensity of smell; it was 0-2 points. The artificial smell at point 3 associated with the presence of parking, where passenger gasoline cars are mainly located. The smallest number of cars was observed on Levanevskogo Str. but the melted water had an earthy smell. The samples of melted water didn't smell in observation points 4 (crossroads of the streets Druzhba and Zamkova), 6 (Geroiv Chornobylia Str.) and 7 (park Oleksandriia). On this index the above-mentioned points are clean among those that were determined. The high level of pollution was on the blvd. 50-richa Peremogy at 1 m distance (463,5 mg/m <sup>2</sup> per day). The medium level was at the same point at 5 m distance (277,3 mg/m <sup>2</sup> per day), Skvyrske shosse at 1 m distance (325,0 mg/m <sup>2</sup> per day) and at the crossroads of the streets Prymakova and Geroiv Chornobylia at 1 and 5 m distance. In the analysis of monitoring data of the snow cover it is taken into account the traffic number that was the largest in these points. The cleanest area was on Geroiv Chornobylia Str.: the amount of dust at 1,5 and 10 m distance was the lowest among all the points that were studied.
