Answer:

There is inverse relationship between DDT use and bald issue reproduction

Explanation:

Dichlorodiphenyltrichloroethane, is commonly known as DDT, which is a colorless, tasteless, and almost odorless, crystalline chemical, an organochlor. Originally developed as an insecticide, it is famous for its environmental impact. DDT was synthesized first in 1874 by the Austrian chemist Othmar Zeidler. The breeding of bald eagles in northwest Ontario rose from 1.26 offspring per breeding area in 1966 to a low of 0.46 in 1974 and then rose to 1.12 in 1981. The DDE residues in the added eggs showed a significant inverse relationship, confirming the effects of toxin on population-level bald head reproduction and the effectiveness of the DDT ban. The recovery from DDE contamination in the bald eagle appears to be much faster than expected.
