During World War II it was used to fight typhus and malaria, and in 1945 the US Food and Drug Administration (FDA) approved it for public insecticide use. via
Why is DDT still an environmental concern today?
The reason why DDT was so widely used was because it is effective, relatively inexpensive to manufacture, and lasts a long time in the environment (2). Is DDT still used? DDT was canceled because it persists in the environment, accumulates in fatty tissues, and can cause adverse health effects on wildlife (4). via
What does DDT do to animals?
DDT affects the central nervous system of insects and other animals. This results in hyperactivity, paralysis and death. DDT also affects eggshell production in birds and the endocrine system of most animals. DDT has a very high tenancy towards biomagnification. via
What does DDT look like?
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochloride. Originally developed as an insecticide, it became infamous for its environmental impacts. via
Do insects eat DDT?
When DDT was first used it was not only very effective but apparently also relatively harmless. DDT is designed to be especially toxic to insects, and other species such as birds are more sensitive than mammals such as humans. via

The only solution is to exterminate the mosquitoes that spread these diseases by pesticides. The most potent of these is DDT. The US National Academy of Sciences estimated DDT had saved 500 million lives from malaria by 1970. via
How do you neutralize DDT?
Common DDT-contaminated sediment remediation options include dredging, capping, and natural attenuation. Sediment washing and phytoremediation have also been used in contaminated sites. via
How do you dispose of DDT powder?
Call your local hazardous waste disposal site. Many counties have a drop off point or a yearly pick up. Never incinerate or dump DDT. via
Does DDT cause infertility?
Residual DDT and PCBs in the environment cause birth defects and male infertility. Organochlorine chemicals, such as DDT and PCBs, were banned in the United States in the 1970s, but that doesn't mean they're gone.
