Answer 3

DDT
*************
Peregrine falcons declined precipitously in North America following
World War II (Kiff 1988). Research implicated organochlorine
pesticides, mainly 1,1,1-trichloro-2,2-bis(p-chlorophenyl)-ethane
(DDT), applied in the United States and Canada during this same period,
as causing the decline (for a review, see Risebrough and Peakall 1988).
Use of these chemicals peaked in the 1950s and early 1960s and
continued through the early 1970s. Organochlorines and their
metabolites, including DDT and its principal metabolite DDE (1,1-
dichloro-2,2-bis(p-chlorophenyl)-ethylene), aldrin, dieldrin, and
others, are stable, persistent compounds that are stored in the fatty
tissues of animals ingesting contaminated food (Fyfe et al. 1988).
Peregrine falcons and other animals near the top of the food web,
including ospreys (Pandion haliaetus), bald eagles (Haliaeetus
leucocephalus), and brown pelicans (Pelecanus occidentalis), gradually
accumulated these toxins by eating contaminated prey.
