Investigation of atmospheric conditions in stanbul leading to air pollution episodes

Combined SO2 and total suspended particulate (TSP) concentrations from different locations in stanbul province were used to investigate intense air pollution episodes from 1985 through 1991. Occurrence of intense episodes was found only after November 1989. These episodes were associated mainly with high-pressure systems, inversions and low wind speeds. The European side of the Bosphorus was found to be more polluted than the Asian side, probably because of weaker dispersion and the greater use of poor-quality fuels.
