Phenol monitoring in the air of the city residential part

Abstract

In order to monitor the chemical composition of atmospheric air in cities located in the zone of petrochemical enterprises influence, automatic atmospheric air monitoring stations (AAAMS) are being established. The concentration of phenol and methanol in the air of the residential part of the city is recorded at AAAMSs. In the industrial zone air, the methanol content is measured at the source of pollution. Processing the numerical series of the measured concentrations values using the cross-correlation function allows you to get the time lag of the contaminated gas cloud moving from the source of emission to the city. Models have been developed for changes in concentration of phenol in the air of the residential area using the factor regression method, taking into account the concentration of the analyzed compounds, the time lag from the source of pollution to the living area and weather conditions: - air temperature and humidity, wind direction and speed.
