The sampling site was a campus and considered as a semi-rural site. Atmospheric OCPs in the particulate and gas phases were measured separately during night and day time periods. The average of the total concentrations was determined as 599 +/- 194 pg/m(3) and on average 65% of the total OCP concentration was in the gas phase. Measured OCP level were comparatively greater in the warmer months of June, July, and August. The temperature dependence of gas-phase atmospheric concentrations of OCPs was examined using the Clausius-Clapeyron approach. The temperature effect was statistically significant (p &lt; 0.05) on the Alpha, Gammaand Delta-HCH, and Methoxychlor concentrations for night samples, yet it was not statistically significant for the day samples. The maximum annual average gas phase OCP concentration was measured for Beta-HCH species as 176 pg/m(3). The maximum value was 67 pg/m(3) in the particle phase and it belonged to Beta-Endosulfan. The partitioning of OCPs between particle and gas phases was studied. They were compared to the P-L(o) (supercooled vapor pressure) and KOA (octanol/air partition coefficient) models. OCP concentrations measured during the day and night-time periods were found to be close to each other. The absence of a significant difference in night day concentrations has shown that the impact of local sources were similar. Inhalation carcinogenic risks of OCPs were calculated and they indicated low cancer risk.</subfield> </datafield> </record>
