Hydrocarbons and chlorinated hydrocarbons in the air in the greater Split area.

The content of hydrocarbons and chlorinated hydrocarbons was examined in samples of air from the greater Split area. Organic pollutants were accumulated from the air by adsorption on Polysorb-10 and desorption with hot water vapour. Gaseous and liquid phases were analysed by gas chromatography. Hydrocarbon concentrations were within permissible limits and their effects on human health were negligible. There were marked differences between pollutant concentrations in air samples taken from the industrial zone, crossroads in the city centre and "clean" zones.
