After surface application,50% of DDT was lost within 16-20 days.

In some instances where the worker was leaning over the tank or using a brush to scrub the surface coating, concentrations of > 7100 mg/m3 have been recorded (McCammon et al., 1991; HSE, 1992).

Some measured ranges, e.g., 35-81 mg/m3 and 85-244 mg/m3 (HSE, 1992), indicate that engineering control techniques can bring 8-h TWA exposures below 350 mg/m3.
Oral LD50 values of 1410-3000 mg/kg were recorded.
Moffett & Yarbrough (1972) investigated the enzyme succinicdehydrogenase in insecticide-resistant and insecticide-susceptiblemosquitofish ( Gambusia affinis ) in an attempt to discover ifresistance could be related to membrane effects of DDT.
