New Hampshire Sets Strictest TCE Standard In Country For Cardiac Effect

摘要

The New Hampshire Department of Environmental Services (DES) has adopted what appears to be the strictest permanent measure yet in the country to protect against cardiac birth defects from short-term exposures to trichloroeth-ylene (TCE), calling for the relocation of women of child-bearing age from residences if TCE levels in indoor air reach a level EPA set in 2011 to protect against non-cancer health effects over a lifetime of exposure.The new measure DES announced in a Feb. 7 memo is stricter than levels several EPA regions have enacted over the last year since EPA's Integrated Risk Information System (IRIS) assessment for TCE linked short-term exposures to TCE to a risk of cardiac birth defects but did not set a limit to protect against non-cancer risks from short-term exposures.
