Assessment and risk prevention of air pollution in urban sites

Abstract

Atmospheric pollution limitation has evolved and evolves continuously, depending on the better knowledge of the harmful effects of the different atmospheric pollutants. The main elements that have led and lead to the continuous revision of the norms are the climatic changes and acid rain associated with atmospheric pollutants. In this context, the paper presents the following aspects: two monitoring regimes aims to evaluate and prevent air pollution in urban areas; was chosen as a monitoring location Constanta city, with strategic points exposed to the risk of pollution. For the monitoring of emissions in these locations, a selfemployed emission analyzer was used. Where there are risk areas, exists a risk analisys with vulnerable locations and values of emissions’s concentrations. There are monitoring CO, CO2, NO2, SO2 emissions and PM2.5 and PM10 in air of urban sites which are exposed to the risk of pollution. Finally, the recorded values are below the maximum permissible limit. The conclusion is that pollution in urban sites can also be a danger to neighboring rural settlements, if there is no strict monitoring thereof.
