Some of the pesticides sprayed on farm crops wash off in the rain and get into the waterways. The water plants absorb the pesticides.
air,soil and water only
DDT from soils is drained to water after rains and floods.
DDT is not very soluble in water. It is more soluble in organic solvents like benzene and ethanol.
DDT is not soluble in water.
The concentration of DDT is lower in water than in organisms because of bioaccumulation. Organisms absorb DDT from water through their food or direct exposure, leading to higher concentrations in their bodies compared to the surrounding environment. As DDT moves up the food chain, its concentration increases at each trophic level, resulting in higher levels in organisms than in the water.

DDT can be determined in soils, waters, plants, etc.

Yes, many animals and plants have been tested and proven to contain DDT years after it was applied to crops many miles away. The most notable case is that of the American Bald Eagle, whose eggshells were weakened by DDT contamination, threatening the entire Bald Eagle population for years. Some years after DDT was banned in the US, the eagle's normal reproductive cycle was restored, as the DDT levels in their blood was reduced.
DDT concentration is higher in ospreys because they eat the animals that have concentrations of DDT in it. As DDT passes up the food chain it gets more and more concentrated. THis is due to the 10% rule. wiki it.
Your premise is incorrect; DDT does not kill birds. DDT kills mosquitoes.
Typically, zooplankton accumulate higher concentrations of DDT in their bodies compared to small fish. This is due to a process called biomagnification, where toxins like DDT become more concentrated at each level of the food chain. Zooplankton, being at the base, absorb DDT from the water and sediments, and when small fish consume them, the concentration of DDT increases in the fish. Thus, while both may contain DDT, small fish generally have higher levels due to their position in the food web.
DDT, or dichlorodiphenyltrichloroethane, is not particularly reactive with water. It is only slightly soluble in water and tends to persist in the environment for long periods of time. However, DDT can undergo hydrolysis in the presence of water under certain conditions.
