Is DDT is non-biodegradable?
DDT (dichlorodiphenyltrichloroethane) is a persistent organic pollutant that is considered non-biodegradable in the environment. It can remain in the environment for a long time, accumulating in organisms and the food chain, leading to harmful effects on wildlife and humans.
Is ddt a mixture or compound?
Chlorine is an elemental gas, but is technically a compound in its naturally occurring state because, like many gases, it occurs as CL2, rather than Cl. It can be part of a mixture if it is in solution with other gases or liquids.
What is the full form of pop chemical that pollute the environment?
POP stands for Persistent Organic Pollutants. These are chemicals that are resistant to environmental degradation, accumulate in the environment, and pose risks to human health and ecosystems. Examples include pesticides like DDT and industrial chemicals like PCBs.
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.
When was pesticide invented?
The first synthetic pesticide, dichlorodiphenyltrichloroethane (DDT), was discovered in 1874 by Swiss chemist Paul Hermann Müller, but it was not widely used until the 1940s. Organic pesticides, such as sulfur and arsenic, have been used for centuries to control pests.
What is the solute and the solvent of DDT?
DDT as solute is soluble in organic solvents.
Is DDT soluble in water?
DDT is not very soluble in water. It is more soluble in organic solvents like benzene and ethanol.
The definition of chlorinated organic insecticide best fits which of these science terms?
DDT
What is the abbreviation 'DDT'?
A chlorinated organic compound is what DDT is.Specifically, the organochloride in question carries the abbreviation DDT, for dichlorodiphenyltrichloroethane. It has no color or taste and very little odor. Its most famous use is as an effective insecticide with environmental after- and side-effects.
How many elements are there in ddt?
DDT contains 3 elements: carbon, hydrogen, and chlorine.
Why might people who understand DDT disagree to DDT?
People who understand DDT may disagree with its use due to environmental concerns. DDT is a persistent organic pollutant that accumulates in the environment and can harm non-target species, including humans. Alternatives that are less harmful to the environment and human health are available for pest control.
What are the regulations for the use of DDT in New Zealand?
DDT cannot be used in New Zealand. New Zealand has signed and ratified the Stockholm Convention on Persistent Organic Pollutants which includes DDT. DDT was prohibited from use on New Zealand farmland in 1970, and its production and sale for all other purposes was banned by law in 1989.
Is DDT is non-biodegradable?

Why was it bad when DDT was in the organic matter?
Traces of DDT are still in the environment, although continuing to degrade. The problem with DDT is that it caused bird egg shells to thin causing the eggs to break, particularly in birds of prey at the top of the food chain. We very nearly lost the Bald Eagle and the Peregrine Falcon, who are now doing very well.
What are organic pollutant?
Organic pollutants are persistent organic pollutants(POPs). Examples are DDT and lindane, industrial chemicals such as polychlorinated biphenyls (PCBs), and substances such as dioxins, all of which accumulate and are slow to degrade, and may have adverse impacts on human health and the environment.
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.
Why does DDT exist?
