DDT. Common name: Agritan, Anofex, Azotox, et al. <br /> Half-lives in the environment: <br /> Air: 17.7 -177 h. <br /> Surface water: 73.9 h for a pond 1 m deep. Degradation half-life of about 10 yr- <br /> average from loss rates determined in Lake Michigan. <br /> Groundwater: 16 d to 31.3 yr. <br /> Sediment: 3 to 5 yr <br /> Soil: 2-15.6 yrs based on observed rates of biodegradation in aerobic soils under <br /> field conditions. Avg. half life of-12 yrs in 3 different soils for -50 ppm in soil. <br /> (conversion of p,p'-DDT to p,p'-DDE). <br /> Environmental Fate Rate Constants or Half-Lives: <br /> Volatilization: Half-life of 3.7 d for water depth of 1 m, from soil w/h-1 of 578 h <br /> Oxidation: Photooxidation half-life of 168-8400 h in water, 17.7-177 h in air <br /> Hydrolysis: Estimated first-order half life of 22 yr <br /> Biodegradation: Aqueous aerobic half-life of 2-15.6 yrs <br /> DDE. Common name: DDE (p,p'-DDE; o,p'-DDE), product of DDT degradation. <br /> Half-lives in the environment: <br /> Air: Atmos. transformation lifetime est. to be< 1 d. <br /> Surface water: Hydrolytic half-life of >120 yr, est. half-life>300 d in lakes. <br /> Groundwater: N/A <br /> Sediment: N/A <br /> Soil: Field half life of 1000 d <br /> Biota: Elimination half-life of 340 d(rainbow trout), 300 d for birds. <br /> Environmental Fate Rate Constants or Half-Lives: <br /> Volatilization: N/A <br /> Oxidation: N/A <br /> DDD. Common name: DDD, TDE (tetrachlorodiphenylethane), product of DDT deg. <br /> Half-lives in the environment: <br /> Air: 17.7-177 h <br /> Surface water: 2-15.6 yr. <br /> Groundwater: 1680-270,000 h based on anaerobic soil study data <br /> Sediment: N/A <br /> Soil: Field half life of 2-15.6 yrs based on observed rates of biodeg. of DDT <br /> Biota: 119 hr in mussels. <br /> Environmental Fate Rate Constants or Half-Lives: <br /> Volatilization: Aquatic approx. I mo. <br /> Oxidation: Aquatic half-life approx. 22 yr <br /> Hydrolysis: half-life of 570 d @ pH 9 and 190 yr @ pH 5 <br /> Biodegradation: Aqueous aerobic half-life of 2-15.6 yr <br />
