1. Introduction to DDT: DDT (Dichloro-Diphenyl-Trichloroethane) is a synthetic chemical compound that is widely used as an insecticide to control pests that damage crops. 2. Properties of DDT: DDT is insoluble in water but soluble in fats. This characteristic affects how it behaves in the env...
A mixture of hemin and excess cysteine (the hemin ? cysteine model system) is able to degrade DDT partially and the major degradation products are three water-soluble, non-toxic conjugates of DDT metabolites with cysteine which lose two or three of the five chlorine atoms of DDT. In the ...

The solubility of dithiothreitol has been tested by Sigma at 50 mg/ml in water, resulting in a clear colorless solution. It has been described as freely soluble in water, ethanol, acetone, ethylate, chloroform and ether. Solutions oxidize relatively slowly in air.3It is recommended to make ...
(or 533 kelvin). however, it is important to note that ddt undergoes decomposition when it is heated to this temperature range. ddt is very poorly soluble in water. for all practical purposes, this compound is insoluble in water. the solubility of dichlorodiphenyltrichloroethane in water ...
Chemically, it is a crystalline white solid, practically odorless and tasteless; insoluble in water, but soluble in most organic solvents; stable on exposure to air and sunlight. Recent work by the U. S. Public Health Service, Lillie and Smith (1944), and Smith and Stohlman (1944), shows...

The total environmental fate of -hexachlorocyclohexane (-HCH, lindane) and dichlorophenyltrichloroethane (DDT) in agriculture were studied.DDT is mostly present in the soils, the water-soluble -HCH in soils and ocean. DDT has the longest residence time in almost all compartments. Quasi-steady ...
DDT is very stable, relatively insoluble in water, but highly soluble in fats. Health effects on humans are not clear, but it is less toxic than related compounds. It is poisonous to other vertebrates, especially fish, and is stored in the fatty tissue of animals as sublethal amounts of ...
