What is bioaccumulants?
Bioaccumulation is the building up of toxins in a food chain. Since toxins like, for instance, DDT, are not soluble in water and are instead stored in the fatty tissues, their levels raise each tier you go up on the food chain. I'll give you an example...Plankton, at the bottom of the food chain, eat small particulates and algae, but also take in small levels of mercury.Small fish then eat the plankton. The mercury concentrates further - remember, DDT and mercury are not water soluble toxins, so they can't be passed through urine or feces.Large fish may eay up to 1,000 small fish in their lifetime. The mercury reaches dangerous levels for humans, and may cause genetic mutations in the fish's reproductive habits (ie, size of eggs, number of eggs, etc).Oceanic birds eat large and small fish. The mercury causes more genetic defects, including thinner eggshells.As you can see, bioaccumulation poses a real danger to certain ecosystems, especially since many areas were sprayed with DDT in the 60's and 70's.
What does the wrestling move ddt stand fot?
ddt in wrestling stands for direct diving takedown
What color is DDT?
White.
What is full form of DDT?
Dichlorodiphenyltrichloroethane
What was not a scientific finding that led to the ban on DDT?
There are inumerable examples. The time dilation effect of relativity had essentially nothing to do with the reasons for the ban on DDT. Yes, that was an important one, but it was less unassociated with DDT than the link between vitamin deficiency and scurvy, and the isotropic expansion of the universe were.
What physical property od DDT contributes to its bioaccumulation in animals?
The physical property of DDT that contributes to its bioaccumulation in animals is its inability to break down easily. This results in it being stored in the fatty issues of animals.
Why are 2nd order consumers are more likely to be affected by the DDT than the 1st order consumers?
BIOACCUMULATION
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 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 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.
How does the DDT originnaly enter the food chain?
DDT originally enters the food chain through runoff from agricultural fields or from direct application to crops. It can then be absorbed by plants and accumulate in the tissues of animals that eat these plants. This process is known as bioaccumulation.
Where do you use DDT?
DDT (dichlorodiphenyltrichloroethane) is mainly used as a pesticide in agriculture to control disease-spreading insects like mosquitoes. It has also been used in the past for its insecticidal properties in controlling pests in homes and public health programs. However, due to its persistence and bioaccumulation in the environment, DDT has been banned or its use severely restricted in many countries.

Why would the concentration of ddt be less in water than in another organism?
The concentration of DDT is lower in water than in organisms because of bioaccumulation. Organisms absorb DDT from water through their food or direct exposure, leading to higher concentrations in their bodies compared to the surrounding environment. As DDT moves up the food chain, its concentration increases at each trophic level, resulting in higher levels in organisms than in the water.
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 the concept of bioaccumulation about?
The concept of bioaccumulation is when there is an unusual accumulation of a substance such as pesticides or toxins in a living organism. This could refer to something such as mercury being found in fish. This type of contamination can occur from water, food, air or soil.
