A method to sample and analyse lindane and three endosulfan isomers in greenhouse air has been studied. The behaviour of Chromosorb 102, Porapak R, Supelpak-2, Amberlite XAD-2, Amberlite XAD-4 and polyurethane foam (PUF) as sorbents has been studied. Atmospheres containing known concentrations of these pesticides were generated. The desorption process of the analytes and the behaviour of sorbents in atmospheres with different relative humidities have been tested. No breakthrough was observed in the range of concentration studied. Personal samplers have been used with the selected sorbent (PUF), in order to sample lindane, α- and β-endosulfan and endosulfan sulfate in an experimental greenhouse. GC—electron-capture detection analysis and MS confirmation of the pesticides have been carried out. The dissipation process of the analytes in the 24 h period after application has been studied.
