In Other Species
Humans are not alone in suffering from lead's effects; plants and animals are also affected by lead toxicity to varying degrees depending on species. Animals experience many of the same effects of lead exposure as humans do, such as abdominal pain, peripheral neuropathy, and behavioral changes such as increased aggression. Much of what is known about human lead toxicity and its effects is derived from animal studies. Animals are used to test the effects of treatments, such as chelating agents, and to provide information the pathophysiology lead, such as how it is absorbed and distributed in the body.
Farm animals such as cows and horses as well as pet animals are also susceptible to the effects of lead toxicity. Sources of lead exposure in pets can be the same as those that present health threats to humans sharing the environment, such as paint and blinds, and there is sometimes lead in toys made for pets. Lead poisoning in a pet dog may indicate that children in the same household are at increased risk for elevated lead levels.

Famous quotes containing the word species:
“The French manner of hunting is gentlemanlike; ours is only for bumpkins and bodies. The poor beasts here are pursued and run down by much greater beasts than themselves; and the true British fox-hunter is most undoubtedly a species appropriated and peculiar to this country, which no other part of the globe produces.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
