second, tsca implementation is difficult because of the number of chemicals in the us market and high costs associated with fully assessing the toxic impacts of so many chemicals on human health and the environment. 62,000 chemicals on the market at the time were listed on the original tsca inventory of chemical substances. tsca "grandfathered" these 62,000 chemicals, allowing these substances to remain on the market without first assessing toxic impacts. new chemicals, however, would be subject to review for health and environmental risks. since then number of chemicals listed on the tsca inventory has grown to roughly 84,000. the epa has only required approximately 200 of these 84,000 chemicals to be tested, and of the 22,000 chemicals introduced since 1976, chemical manufacturers have produced very little data for the epa on potential health and/or environmental impacts.
