Routes of reduction and degradation involve runoff, volatilization, photolysis and aerobic and anaerobic biodegradation. As a result of hydrophobic properties, in aquatic ecosystems DDT and its metabolites are absorbed by aquatic organisms and adsorbed on suspended particles, leaving little DDT dissolved in the water (having said that, its half-daily life in aquatic environments is mentioned because of the Countrywide Pesticide Facts Center as a hundred and fifty many years[fifty nine]).
