DDT remains are found insecticides to continue with “worrying rates” in the thickness of the knitted salmon even after 70 years, which may pose a great danger to humans and wildlife that eats fish.
Dichlorodiphenyltrichloroethane, known as DDT, was used on forest lands in New Bronzwek, Canada, from 1952 to 1968. The researchers found that its effects remained in the thickness of salmon in some lakes, often 10 times higher than the recommended safety threshold for wildlife.
“DDT is a potential carcinogen that we have not used for 70 years here [Canada]”However, it is abundant in clay in fish and lake in most of the provinces at high levels,” said Josh Cork, associate professor of environmental change and water surveillance at Mount Alison University in Canada.
Search, Posted in Plos OneDisc discover that DDT pollution covers about 50 % of New Brunswick Province. Troot Brock is the most common wild fish in the region, and found the research that was found that D. D. T is in muscle tissue, in some cases 10 times above the recommended Canadian wildlife guidelines.
The researchers said that the D. D. T, which is classified by the health authorities as a “potential carcinogenic substance”, can continue in the lake clay for decades after treatment and that many lakes in New Bronzwek maintain high levels of D. D. T. Springs is a major source of pollution in the food network.
“The audience, especially the weak population of pollutants such as women of childbearing age and children, should be aware of the dangers of exposure to the heritage of Democrats through wild fish consumption,” said Corik.
Throughout the fifties and sixties of the last century, half of the DDT forests were sprayed using DDT, an artificial insecticide used to control insects that carry diseases such as malaria and Tivus. Canada banned the use of the material in the eighties.
The 2001 Stockholm Convention on continuous organic pollutants around the world for collective agricultural use, although it is still allowed in small quantities to control malaria.
“This chaos cannot be cleaned,” Corik said. “DDTS can continue in the lake clay for decades for centuries and then revolve around the food network. The best way is to manage the audience’s exposure to the old DDTS by encouraging everyone to follow the instructions of fish consumption and thinking about reducing exposure.

“The results we have reached are a clear invitation to wake up to abandon excessive dependence on artificial chemicals. Lessons must be learned so that we do not repeat past errors. We hope that our studies on other pollutants will learn to apply them widely today, such as road salt and herbal pesticides such as pollution.
