What else can I help you with?
Carnivorous birds that fed on organisms exposed to this chemical produced fragile eggs The chemical is?
The chemical is likely DDT, a pesticide used in the past. DDT accumulated in the tissues of organisms, resulting in fragile eggshells when carnivorous birds like eagles or hawks consumed contaminated food. This eventually led to population declines in these bird species due to reproductive issues.
Why is DDT a persistent chemical?
DDT is a persistent chemical because it is resistant to degradation by natural processes like sunlight, heat, and microorganisms. This allows it to remain in the environment for a long time, accumulating in organisms and biomagnifying through food chains.
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 causes the breakdown of DDT?
DDT can break down through various processes, including sunlight exposure (photolysis), microbial degradation, and chemical reactions. These breakdown processes can lead to the formation of DDE and DDD, which are also considered harmful compounds.
When was ddt first made?
DDT, dichlorodiphenyltrichloroethane, was first synthesized in 1874, but the insect killing properties of this chemical were not realized until 1939. It was eventually banned in the US and some other countries because of the hazards it poses to other life. A link can be found below.
