A recent study published in Environmental Science and Technology notes that even since being banned over 50 years ago, DDT (Dichlorodiphenyltrichloroethane) still remains in the sediment of lakes. Wow, talk about persistence.
The study further notes that this residue, and the toxic byproducts that are formed when DDT breaks down, are effecting the sustainability of the food webs within these lakes.
Yet another example of why we should be proving chemicals safe before they are used rather than being forced to prove that they are harmful to have them removed.
