DDT (dichlorodiphenyltrichloroethane) is a lipophilic compound, meaning it has a strong affinity for fat. When DDT is absorbed into the body, it tends to accumulate in fatty tissues rather than being excreted, due to its chemical structure and stability. This accumulation occurs because the body metabolizes and eliminates water-soluble substances more readily, while fat-soluble compounds like DDT are retained in fat cells. Over time, this can lead to higher concentrations of DDT in organisms, particularly in the case of long-lived species at the top of the food chain.

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 meaning by bioaccumulation and how does it apply to DDT?
Bioaccumulation refers to the accumulation of a substance in an organism's tissues over time. In the case of DDT, a pesticide used in the past, it bioaccumulates in the fatty tissues of organisms as it moves up the food chain. This can lead to higher concentrations of DDT in organisms higher up the food chain, posing potential risks to those predators.
Why ddt build up in an animals tissue?
DDT (dichlorodiphenyltrichloroethane) builds up in an animal's tissue through a process called biomagnification. This occurs when animals at higher trophic levels consume prey that contains DDT, leading to an accumulation of the chemical in their bodies over time. DDT is lipophilic, meaning it is stored in fatty tissues and not easily excreted, resulting in higher concentrations in predators than in their prey. Consequently, as you move up the food chain, the concentration of DDT increases, posing risks to wildlife and humans alike.
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.
How does DDT get into the bodies of zooplankton?
Herbivores (like deer) eat the plants that it gets spread on. We'll say the plants have 1 piece of DDT. Since each deer eats LOTS of individual plants (we'll say leaves), the DDT in the deer will be more than the leaves had. We'll say this deer ate 100 leaves in one day, now it has 100 pieces of DDT in it. Then a wolf comes along and kills the deer and eats all the deer. Now the wolf has 100 pieces of DDT in it. The wolf kills ANOTHER deer the next day and eats it, and now this wolf has 200 pieces of DDT in it. So on and so on. So the MORE DDT you have in an organism's system, the more toxic it is. We call this bioamplification. Each food level it increases GREATLY in the fatty tissues.
Does ddt accumulate in the environment?
DDT is fat-soluble and tends to build up in the fatty tissues of predators and scavengers.
Is ddt polar?
It is non-polar. There are no partial charges.
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.
Which pesticides are most lipophilic?
Organochlorine pesticides, such as DDT and chlordane, are known to be highly lipophilic. These compounds tend to accumulate in fatty tissues due to their molecular structure, which can lead to bioaccumulation in organisms within the food chain.
What is meaning by bioaccumulation and how does it apply to DDT?
Bioaccumulation refers to the accumulation of a substance in an organism's tissues over time. In the case of DDT, a pesticide used in the past, it bioaccumulates in the fatty tissues of organisms as it moves up the food chain. This can lead to higher concentrations of DDT in organisms higher up the food chain, posing potential risks to those predators.
What body tissue is DDT stored in humans?
DDT can be stored in fatty tissues of humans. In women who are pregnant, DDT exposure can occur even in the fetus.
Is DDT a fat soluble pollutant?
Yes, DDT (dichloro-diphenyl-trichloroethane) is a fat-soluble pollutant. This characteristic allows it to accumulate in the fatty tissues of organisms, leading to biomagnification in the food chain. As a result, higher concentrations of DDT can be found in larger predators compared to their prey, posing significant environmental and health risks.
Ddt and related compounds are primarily stored in?
DDT or dichlorodiphenyltrichloroethane is a colorless crystalline substance that is used as an insecticide. DDT and some related compounds are primarily stored in fats and other organic solvents.

What is a fatty substance found only in animal tissues and ecreted in bile?
What is a fatty substance found only in animal tissues
What is the relationship between biological magnification and the reduction of the bald eagle population by pesticide DDT?
because DDT accumulates in fatty tissue, DDT concentrations increase as this chemical moves up in the food chain because at the top of the food chain, DDT concentration has increased almost 10 million times
