These pesticides have toxic effects on humans beings and other animals.
Some of the pesticides sprayed on farm crops wash off in the rain and get into the waterways. The water plants absorb the pesticides.
DDT is toxic for humans and animals.
DDT is dichlorodiphenyltrichlorethane; biomagnification of DDT in some organisms is possible.
There are probably a number, but generically, they are those pesticides made in a factory out of simple ingredients (eg DDT - dichlorodiphenyltrichloroethane) rather than those that are extracted from living things (eg Pyrethrum)
The organisms at thetop of the food chain will contain the most DDT. These are the top carnivores (or humans if we are in the food chain).DDT builds up in food chains for several reasons:1) It is a persistent pesticide IE: it is difficult for any organisms to break it down, it is non-biodegradable.2) It is soluble in fat, so it enters the fat storage tissue (adipose tissue) and stays there.3) Organisms higher in the food chain consume DDT every time they feed on organisms lower down in the food chain, if they are contaminated with DDT.4) The biomass at each level in a food chain gets less, so the concentration of DDT will increase.The increase in concentration of pesticides in a food chain is called bio-magnification.Additional Information: Seals, Predatory Fish, Bears, Predatory Birds, Bats.

insectisides,pesticides,chemicals like ddt etc. kill mosquitoes
CARSON
Rachel Carson, an American marine biologist and author, was most responsible for alerting the public to the risks involved in DDT spraying. Her book "Silent Spring," published in 1962, documented the harmful impacts of pesticides on the environment and raised awareness about the dangers of DDT to wildlife and human health.
chloral
an increase in chemicals and pesticides like "DDT" can damage an ecosystem
Birds of prey, such as peregrine falcons and bald eagles, had some of the highest levels of DDT in their bodies due to biomagnification through the food chain. This accumulation of DDT caused reproductive issues and population declines in these species. Efforts to ban DDT and other harmful pesticides have helped to reduce these impacts.
No. It helped awaken the public to the use of it and helped show the effects of DDT and pesticides on the environment. It was named Silent Springs because she believed that the pesticide would kill the birds and they wouldn't be there in the spring to sing.
the food chain
They got endangere because of the use of DDT and oher pesticides basicly the DDT poisons the rabbits and stuff and in turn poison the falcons
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.
