Özet
The concentrations of organochlorine pesticides (OCPs) in both the gas and particulate phases of urban air samples were determined. The samples were collected between August 2006 and May 2007 at four different locations in Konya, Turkey,. OCPs were analyzed by gas chromatography with micro electron capture detection (GC/mu-ECD). The average total (gas + particulate) concentrations of OCPs were determined to be between 809 and 6309 pg/m(3). The highest OCP levels were found in autumn. Total hexachlorocyclohexane (HCH, sum of alpha, beta, gamma, delta-HCH), total DDT's (sum of p,p(i)-DDT, p,p(i)-DDD and p,p(i)-DDE) and endosulfan compounds (sum of endosulfan I, endosulfan II and endosulfan Sulfate) were about 43, 25 and 17% of total OCPs, respectively. OCPs were predominantly detected in the particulate phase. Correlations were observed between OCP concentration and temperature, relative humidity. wind speed and Total Suspended Particulate. PM10, but the variation between meteorological parameters with OCP concentrations could not be explained completely. Despite banned/restricted use in Turkey, all the OCP were found in urban air. p,p(i)-DDT/p,p(i)-DDE ratios were above 11 which is all indication of current use of DDT compounds. Therefore, it could he suggested that Konya is an actively contributing region to organochlorine pesticides pollutants in Turkey.
