There is little to no toxicity information regarding thousands of chemicals to which people are exposed daily.In fact, of the 84,000 chemicals listed in the United States Toxic Substances Control Act Inventory, there is limited information available on their effects on neural development (Betts, 2010;US EPA, 2015).The number of chemicals tested remains low due to the high cost of conducting multi-generational animal studies and the lack of altative testing methods.
