Abstract

No products of DDT metabolism were detected in surface seawater at temperatures of 4° to 32°C, at various salinities and in the presence or absence of O2. DDD was formed from DDT in surface waters supplemented with Cylindrospermum sp. cells, and both DDD and DDE were produced in surface water-sediment model ecosystems receiving organic amendments. Flooded sediments were especially active in converting DDT to DDD, and an unknown compound accumulated in these sediments. None of a series of compounds known to be generated microbiologically from DDT in vitro was observed in the model ecosystems.
