Herbicides are used routinely for weed control. Most herbicides are quite selective for specific plants and are not as poisonous for animals. Less selective compounds, such as arsenicals, chlorates, and dinitrophenols, are more toxic to animals. Most toxicity pro
A class of organic chemical compounds called halogenated aromatics includes polychlorinated biphenyls (PCB), polybrominated biphenyls (PBB), naphthalenes, benzenes, and diphenyl ethers (PCDE, PBDE), as well as a number of pesticides such as DDT (
Gossypol poisoning is usually longterm, cumulative, and slowly and subtly harmful. It is caused by eating cottonseed or cottonseed products that contain excess gossypol.
Ingestion, inhalation, or direct skin contact with petroleum, petroleum condensate, gasoline, diesel fuel, kerosene, crude oil, or other hydrocarbon mixtures can cause illness and occasionally death in animals. Pipeline breaks, accidental release from storage tan
Penta has been used as a fungicide, molluscicide, insecticide, and as a wood preservative, but its registrations for these purposes have gradually been reduced or cancelled over the years. In the US, pentachlorophenol pesticide use is currently restricted to cert
Poisoning by ingestion of excess urea (a nitrogen compound) or other sources of nonprotein nitrogen is usually sudden, rapidly progressive, and highly deadly. After ingestion, nonprotein nitrogen undergoes a chemical reaction and releases excess ammonia into the
Many species are susceptible to nitrate and nitrite poisoning, but cattle are affected most often. They are especially vulnerable because microorganisms living in the rumen convert nitrate into nitrite, which is 10 times more toxic than nitrate, before nitrite is
Metaldehyde is the active ingredient in molluscicides, which are mostly used during the wet season for slug and snail control. In certain locations, metaldehyde is also used for
