Silent Spring is an environmental science book by Rachel Carson. [1] Published on September 27, 1962, the book documented the environmental harm caused by the indiscriminate use of DDT, a pesticide used by soldiers during World War II.
DDT and polychlorinated biphenyls (PCBs) move from contaminated sediments into the water, so although the dumping of DDT stopped in 1982, the Palos Verdes Shelf remains contaminated. [6] DDT and PCBs enter the food chain through worms and micro-organisms living in the sediment. Fish may eat many of these organisms, causing the DDT and PCBs to ...

Māpua was one of the most contaminated sites in New Zealand due to pesticide residues in the soils from a now defunct factory. In the 1940s organomercury and organochlorine pesticides, including DDT, DDD, dieldrin, 2,4-D and paraquat, were produced. The factory closed in 1988 and the site was subjected to a major cleanup operation in the 2000s.
