The study is devoted to the estimation of pollution deposit caused by vehicles into the city to-tal greenhouse gases emissions and to the forecast of the secondary air pollution with formal-dehyde. The present study contains mathematic model which allows getting the estimation of vehicles emission in the total amount of polluted atmospheric air. The model consists of two intercon-nected parts: a dynamic and a kinetic one. The first part of the model is based on the Theory of Convective Jet and Thermals in the Atmosphere and allows to get the parameters of the contaminated air which is being formed over the highway. The Dynamic part of the model allows to get the total amount of hydrocarbons emission depending on the number of vehicles which is present at the same time on the highway. We also obtain the data on concentration of pollution and temperature increasing in the narrowest section of the thermal jet. The kinetic part of the model allows to determine the concentration of the secondary atmos-pheric air contamination with formaldehyde as a result of photochemical transformation of hydrocarbons which are the part of emission of internal combustion engine. The speed of the transformation reaction was determined by the Can't Hoff-Arrhenius deferential equation. The given mathematical model was tested with the help of the system of regular observation over the polluted atmospheric air in Kyiv city. The comparison of the estimated value of for-maldehyde concentration and the observation data doesn't exceed 5 % above the maximum values. According to average monthly rates there is a false positive error (to + 20 % in the warmest months). Basing on the given model the calculator of concentration of pollution by vehicles was devel-oped. This calculator allows to obtain rapidly the values of formaldehyde concentration, de-pending on air temperature, solar radiation and number of vehicles on the highway. The amount of hydrocarbon emission from the vehicles, according the suggested model, allows to estimate the deposit of vehicles into the total amount of greenhouse gases of the city. The ob-tained results could be useful in forming of ecological policy of the cities and in managerial decision making.

The water resources are the main component of technological processes occurring in industry; therefore, increasing the level of environmental safety, in particular, wastewater treatment without adverse impact on the environment and human health is relevant. The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company's activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. The studies conducted with the aim of determining the motor transport enterprise sewage composition revealed an excessive content of polluting chemical substances, namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of using carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of wastewater of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing the environmental fees and penalties.
