Variation Pattern of Gaseous Organochlorine Pesticides Concentration in Atmosphere
Min-Kyu Choi , Man-Young Chun
ABSTRACT
  This study was performed to measure gaseous Organochlorine Pesticides (OCPs : heptachlor epoxide, α/γ-chlordane, trans-nonachlor, endosulfan, γ-HCH and p, p′-DDE) concentration using PUF high volume sampler from June, 2000 to June, 2002 in the semi-rural atmosphere.
  Using monitoring data for two years, we tried to investigate the annual cycles of gaseous OCPs. We considered three functions to describe the annual cycle: Gaussian, Lorentzian and sinusoidal functions. These functions accounted for 54~91% of the variability in concentration for each gaseous OCPs, and the sinusoidal function gave the best fits. It was seen that the gaseous OCPs concentration increased during the warmer weather while decreased during colder weather. The variation of the gaseous OCPs concentration was closely similar to the variations of ambient temperature. The annual cycle of endosulfan was strongly higher than in comparison with other gaseous OCPs, while for γ-HCH, the cycle was weakly high and did not show apparent seasonal variation. The position of the annual maximum exists generally late July to early August. The period that showed levels more than a half maximum was from late June to early September.
