Sources of contaminants of pollutants are car engines during the period of praboutGrew, movements through the territory of the enterprise and during operation in idle mode.
Calculation of contaminants of contaminants is performed in accordance with the following methodsiswith similar documents:
- Methodical allowance for calculation, normalization and control of emissions of pollutants inisin the atmospheric air, SPB., Research Institute, 2005.
- Methodology for inventory of emissions of pollutants into the atmosphere of AVTabouttransport enterprises (calculation method). M, 1998.
- add-ons and changes to the methodology for conducting inventory of pollutant emissions into the atmosphere of motor vehicles (calculation method). M, 1999.
Quantitative and qualitative characteristics of pollutants that are released in ATMaboutThe sphere from vehicles, are given in Table 1.1.1.

In the calculations of surface concentrations of pollutants using normative metroaboutDuki calculation OND-86 should be used by the power of EV emissions into the atmosphere, attributed to the 20-minute time interval. The calculation methodology provides for the calculation of the maximum single-timeыThrows, attributed to a 60-minute time interval of averaging.
The duration of the emissions of pollutants from the source being considered is1200seconds for the 3600-second settlement interval. The coefficient of bringing the maximum inыThrows for 20 minute interval is 3600/1200 = 3. The results of the uniformity of the maximum single emissions to the 20-minute interval are summarized in Table 1.1.2.

The calculation is made for an open-car parking, not equipped with heating means. Mileage of vehicles at the entrance is0km, when departure -0km. Engine's time of the engine to the hillaboutRome run when departing from the parking lot -1min, when returning to it -1min. Number of days for the calculation period: warm -366.
The initial data for calculating the contaminations of pollutants are given in Table 1.1.3.
