It was studied in this paper to investigate the deposition characteristics of atmospheric organochlorine pesticides(
OCPs, heptachlor-epoxide, α/γ-chlordane, α/γ-hexachlorocyclohexane, , p,p'-DDT and p,p'-DDE) on
plant(Allum tuberosum). OCPs concentrations in ambient air and plant were measured every two weeks from
July to October. It was observed that the ambient air concentrations of OCPs were increased with increasing
temperature and vapor pressure of OCPs, with decreasing LogKoa of chemicals. But the deposited plant concentrations
of OCPs were increased with decreasing temperature, with increasing LogKoa of compounds.
OCPs was deposited in plant from air since the plant-air fugacity quotients (fplant/fair) of OCPs is lower than
1 in summer. However, it was known that plant is a secondary pollution source of OCPs in air since fplant/fair
of OCPs is greater than 1 in fall. Generally the trend of fplant/fair were decreased with increasing LogKoa of
compounds. The slope and determination coefficient (R²) of regression line between plant-air concentration
ratio[Log(Cp/Ca)] and Log(Koa) in fall were greater than those in summer. In this study, it were revealed that
the relationship between plant-air fugacity quotients (fplant/fair) and LogKoa, and between plant-air concentration
ratio[Log(Cp/Ca)] and LogKoa of OCPs was smaller than those of PCDD/Fs and PCBs which are
homologue compounds.
