Answers (1)

Several pesticides, including DDT, aldrin, and dieldrin, build up in the environment. They are often non-biodegradable and fat soluble. DDT is persistent in the environment because it is not soluble in water and is not washed away by rain. However, because DDT is lipid-soluble, it concentrates in animal body fat. Due to a process known as biomagnification, they are integrated into the food chain and their concentrations multiply at higher trophic levels. There have been reports of the biomagnification phenomena for different types of contaminants, including heavy metals like mercury, copper, and radioactive materials.
