Detailed explanation-1: -DDT is not absorbed through the skin or lungs easily. When DDT enters the body, it tends to be stored in the fatty tissues and is excreted from the body over time. High amounts of DDT exposure can lead to problems with the nervous system and liver.
Detailed explanation-2: -Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.
Detailed explanation-3: -DDT is metabolized slowly by liver microsomal enzymes initially dehydrochlorinating DDT to DDE and reducing to DDD. In some rodents (rats and hamsters, but not mice) DDT induces microsomal liver enzymes to promote metabolism.
