| Abstract: | Abstract 14C‐DDT dissipated gradually from natural water under outdoor conditions and declined to 40% of the applied radioactivity after 5 months. The losses are due to adsorption to particulates and volatilization from the water surface. In natural water DDT undergoes gradual conversion to DDE as the major degradation product and to a lesser extent to DDD. It may be concluded that DDT dissipates and degrades fairly rapidly in subtropical natural waters. Adsorption to particulate matter contributes to partial “removal” of DDT. |
