Bioremediation of soil contaminated with pesticides g-HCH (lindane), DDT and p,p'-DMDT (methoxychlor) has been studied in batch tests. The treatments included different combinations of the following amendments: carbon source, reducing agent, zero-valent iron, surfactant and anaerobic biomass (methanogenic granular sludge or fermented sewage sludge). The tests seeded with both types of anaerobic biomass showed high removal of all pesticides. DDT was transformed into DDD, but accumulation of this metabolite was considerably lower than that resulting from stoichiometric reaction. Addition of a surfactant together with anaerobic biomass further enhanced the effectiveness of the process.

Organochlorine pesticides such as DDT and its metabolites (p,p?-DDT, o,p?-DDT, p,p?-DDD, p,p?-DDE), hexachlorocyclohexane isomers (alpha, beta and gamma (-HCH), hexachlorobenzene (HCB) and selected PCB congeners (28, 52, 101, 118, 138, 153, 180) were analysed in plankton, benthic organisms (Cerastoderma glaucum, Mytilus trossulus, Macoma balthica, Crangon crangon), muscle tissue of fish (Zoarces viviparus, Myoxocephalus scorpius, Clupea harengus, Salmo trutta) and birds (Phalacrocorax carbo, Larus ridibundus). We can observe clear differences in the bio-accumulation pattern of these toxic substances in pelagic organisms or benthos and bottom feeding fish.
