At the same time that DDT was hailed as part of the "world of tomorrow", concerns were expressed about its potential to kill harmless and beneficial insects (particularly pollinators), birds, fish, and eventually humans. The issue of toxicity was complicated, partly because DDT's effects varied from species to species, and partly because ...
Imidacloprid and its nitrosoimine metabolite (WAK 3839) have been well studied in rats, mice and dogs. In dogs the LD 50 is 450 mg/kg of body weight (i.e., in any sample of medium-sized dogs weighing 13 kilograms (29 lb), half of them would be killed after consuming 5,850 mg of imidacloprid, or about 1 ⁄ 5 th of an ounce).
