Wasted money, wasted livesThe EPA's indifference to animal suffering is further evidenced by the fact that it allocates virtually none of its over $600 million annual research budget to the development of non-animal test methods, which are generally more reliable, less costly, and always more humane than animal-based tests. Instead, the EPA erects roadblocks at every turn, refusing to use internationally accepted non-animal tests, while wasting countless taxpayer dollars to fund cruel animal experiments like these:• Mercury Inhalation • Metal Bioavailability Mercury Inhalation:
Metal Bioavailability:
Toxic contaminants such as arsenic and lead can pose a serious health risk to humans, particularly infants and children. However, the EPA is still not sure whether it is worth spending the money to clean up these contaminants on the sites of former mines, mills, and smelter waste facilities. So instead, the EPA has chosen to spend more than $400,000 to fund toxicity studies in pigs in an attempt to estimate human exposures to arsenic and lead from the soil of contaminated sites. The research is being performed under the direction of University of Missouri toxicologist Stan Casteel and involves dissolving toxins in drinking water or mixing them with food, then feeding them to immature pigs. Researchers then measure the levels of lead and arsenic in the pigs' blood or urine.
These EPA-funded poisoning studies are completely unnecessary, however, given that non-animal alternatives have been available and in widespread use by European countries since 1994 and can be conducted for a small fraction of the cost of animal tests. These systems evaluate the degree to which metal toxins are absorbed through a simulated gastrointestinal tract. Soils containing arsenic, lead, or other metals are "incubated" in an acidic solution that mimics the environment in the stomach. The acidity is then reduced and incubation continues for a period intended to mimic the time that would be spent in the small intestine. Enzymes and organic acids are also added to simulate gastric and small-intestinal fluids. The fraction of lead, arsenic, or other metals that dissolves during the stomach and small-intestinal phases represents the fraction that is available for absorption and which is therefore capable of causing toxicity. Please contact EPA head Steve Johnson and ask him to discontinue the EPA's funding of these pig toxicity studies and to replace them with the non-animal method.
