Answer;
-Birth defects
Explanation;
In animals, long-term exposure to DDT can cause death or severe birth defects.
-DDT stands for dichloro-diphenyl-trichloro-ethane. It is an insecticide/pesticide previously used on crops. DDT has an adverse impact on many organisms such as crayfish, fish, shrimp, and other animals such as mammals.
DDT is slightly to moderately acutely toxic to mammals, including people, if eaten.Animals given potentially fatal doses of DDT develop liver lesions and those given DDT over a long period of time develop liver changes. In these animal populations DDT may cause birth and reproductive defects.
