摘要：

The atmospheric concentration of lindane and a-HCH measured at Villeroy (Quebec, Canada) are presented. Time-series and source-receptor recognition techniques permit us to point out that agricultural activities, namely, corn seeding, are mainly responsible for the atmospheric release of lindane. About 350 000 ha of land are used for this crop activity in Quebec, and the period of seeding appears to be concomitant with the highest peak of atmospheric lindane. The relationship of lindane with temperature shows that desorption mechanisms are important processes in the atmospheric lindane buildup. This volatilization might come from soil and might involve old as well as fresh lindane.
