Abstract

A laboratory study was performed to evaluate the influence of β-cyclodextrin (β-CD) complexation on the toxicity for some pesticides (Folpet, Captan, Karathane, TMTD etc.) and pesticide decomposition products (chlorophenols, nitrophenols) in activated sludge systems. The growing (β-CD concentration increases the probability of complex formation and for this reason the suppression of toxicity was expected at higher β-CD concentrations. At a given β-CD concentration (60 mg dm-3) the activity of activated sludge increased over that of untreated control. The sludge adapted to Captan-β-CD complex and to pharmaceutical waste-β-CD complex shows a higher tolerance to Captan and to waste than the sludge adapted only to Captan and to waste.
