Loss of Organochlorine Pesticide Residues during the Infusion Processes of Linden (Tilia cordata Mill.)

Losses of residues of α-hexachlorocyclohexane (α-HCH), β-HCH, γ-HCH, hexachlorobenzene (HCB), heptachlor and its epoxide, p, p ‘-DDE, p, p ‘-DDD, o, p ‘-DDT, p, p ‘-DDT, α-endosulfan, β-endosulfan, endosulfan sulfate, aldrin, dieldrin, and endrin, when linden is subjected to three infusion processes, were studied. Compounds were quantified by gas−liquid chromatography with electron capture detection. Higher losses are found for heptachlor epoxide (HE) and o, p ‘-DDT, in process 1 and for α-HCH, HCB, HE, and aldrin in procedures 2 and 3. Lower losses are obtained for β-HCH in process 2. The best procedure for infusion preparation was procedure 3. Keywords: Pesticides; Tilia cordata Mill.; infusion processes
