Deposition of lindane in Denmark

The deposition of α- and γ-HCH (Lindane) was measured at four different stations in 1990–1992. γ-HCH was found in peak concentrations of 27–122 ng/l in spring and early summer, while the mean concentrations from the rest of the year were about 7 ng/l. The levels of α-HCH were about 2 ng/l without any detectable seasonal variation. The deposited amounts of α- and γ-HCH are probably caused by long-range transport from European countries south and west of Denmark.
