DDT is a pesticide that was used to kill bugs. It's bad for the environment because it was killing the animals that would eat those bugs once they were dead, and the population of those animals was decreasing fast. It was banned once scientists realized what it was doing to the animals.
It depends on the environment you consider. If you are concerned that your environment has too many malarial mosquitos and similar disease transmitting insects it is a very good thing. If you want a pesticide that is generally harmless to many animal species (us included) it is a good thing. If you are worried about the bioaccumulation of materials in birds with subsequent problemss with sterility, thin egg shells and similar, it is a bad thing.
because DDT was accumulating in the fat cells of animals at an alarming rate and was causing different types of problems for the birds at the top of the food insect chain:)
DDT is the insecticide dichlorodiphenyltrichloroethane. DDT was banned because has toxic effects on animals.
DDT is an efficient insecticide but also is dangerous for the environment.
it is good
DDT is used as an insecticide which kills on contact. It is extremely harmful and was banned in United States since 1972. Before it was banned, it was used to protect crops from insect damage, but it killed too many animals and plants, while insect populations grew more and more resistant to DDT. This led to ban in DDT in many countries.
Yes. It does live in the ecosystem, and everything in an ecosystem afects it, so yes
The concentration of DDT in the fish is 430,000 times greater than the concentration of DDT in the water.
Eagle populations recovered after the ban on DDT.
organisms in an ecosystem engage in relationships because they need partners or pairs so they can survive in the ecosystem
Yes, that's why it was banned in 1972 in the USA. and Canada.
DDT is very efficient against mosquitoes.
It killed and endangered many birds.
an increase in chemicals and pesticides like "DDT" can damage an ecosystem
There are no natural predators to keep them in check in new environments.
how dose the pollutant hamrful to the ecosystem
If they are ecosystem?
The eggs are extremely fragile.
DDT (Dichlorodiphenyltrichloroethane) was first synthesized in 1874, but it's insecticide properties weren't discovered until 1939.After finding that DDT was harmful to animals and humans, it was outlawed for most uses in the U.S. in 1972. Subsequently, it was banned for agricultural use worldwide in the Stockholm Convention. So, the short answer is, there should not be *any* DDT present on plants.
Dichloorvos and DDT more effective, but is harmful to other organisms.
When DDT gets into the plasma membrane of your skin, nerve impulses (signals) no longer fire when they are supposed to.Nerve impulse tell the muscles when to contract and relax. Thus, when an organism is poisoned with DDT, it dies by either convulsions or paralysis
DDT (dichlorodiphenyltrichloroethane) is a pesticide. It has nothing to do with global warming. It was however used as an example of the bio-accumulation of chemicals in the ecosystem which may harm animals, fish and birds. DDT was used as an example of these problems in Rachael Carson's book "Silent Spring"
