What is DDT and why does it accumulate in the body?
DDT is a synthetic pesticide that was widely used in the past but has since been banned in many countries due to its harmful effects on the environment and human health. DDT can accumulate in the body through various means, including ingestion, inhalation, and skin contact, and once absorbed, it is stored in fatty tissues where it can persist for years.
Is DDT biodegradable?
No. It is still found, even in pristine environments, decades after its use was banned.
Why DDT is not advisible for humans?
DDT is toxic, cancerigen and very resistant in the environment.
Why was the pesticide DDT banned from use in the US?
Because of DDT birds would lay eggs without shells. Bald eagles became extinct in all states except Florida and Alaska. Pelicans became extinct in Louisiana. After DDT was banned a number of birds were introduced to their historic homelands from Florida and the few other places where they had survived.
What kind of soluble is DDT?
DDT is a fat-soluble compound, meaning it dissolves in fats and oils but is not water-soluble. This property allows DDT to accumulate in the fatty tissues of organisms, leading to potential bioaccumulation and biomagnification in the food chain.
What is a well-written hypothesis about DDT and its effects on the environment?
Because DDT degrades slowly in the environment and is toxic it is considered a polluting substance.
Is ddt polar?
It is non-polar. There are no partial charges.

What was a major factor to ban DDT in US?
DDT is toxic for many living beings; also DDT is accumulated in the environment and organisms and decomposes very slowly.
Are other predators get affected by DDT?
Yes, other predators are affected by DDT, particularly those higher up in the food chain. DDT can accumulate in the bodies of organisms through a process called biomagnification, leading to toxic effects such as reproductive failures, thinning of eggshells, and neurological issues. Birds of prey, such as eagles and osprey, were notably impacted by DDT, leading to significant population declines. The chemical's persistence in the environment further exacerbates these effects, posing risks to various wildlife species.
What are the concerns over DDT?
DDT is toxic for many living beings including humans and the decomposition in the environment is very slowly.
