Bucharest is one of the most polluted cities in Europe, with a very high population density
and intense traffic. Because many residential buildings and shopping centers are located near different busy roads and crossroads, the air pollution induced by traffic affects the inhabitants in the area.
The level of air pollution needs to be constantly monitored in order to take appropriate measures
when the concentrations exceed the limits. Most of the measurement techniques require time and
expensive equipment, therefore, a big attention turned into finding an air pollution indicator that
could be precise enough, easily and cheap to determine. The paper presents some preliminary studies regarding the correlation between noise pollution and the concentrations of NO2, SO2, CO. The
measurements were conducted at different distances from some very busy roads and crossroads in
order to determine a pattern. The data have been processed with a statistical analysis program in
order to establish if the noise level can be used to assess the urban air pollution generated by traffic. Most of the results indicate a good correlation between noise and chemical pollutants. Noise level can be a good indicator for air pollution, especially for the situation when there is no need of a precise determination.
