1987年4月16日环保局宣布甲醛为人体可疑致癌物。这一宣布对职业安全与卫生管理局(OHSA)修改甲醛卫生标准有何影响,暂时尚难预料。该宣布是基于对接触工人进行的健康危险度的估价。环保局毒物办公室主任Elkins认为目前环保局必须确定,是否必须按照毒物管理法则进行危险性管理,目前OHSA正设法控制车间内对甲醛的按触并重新考虑修订该化学物质的现行标准。OSHA建议宜将接触阈限值从现在的3 ppm降到1或1.5 ppm。Elkins认为虽宣布了甲醛是人体可疑致癌物,但所依据的数据还存在一些疑问。因此是否需要控制甲醛的使用,还需进一步考虑。环保局综合了28个流行病学调查,其中9个材
April 16, 1987 EPA announced that formaldehyde is a suspicious human carcinogen. This announcement for the Occupational Safety and Health Administration (OHSA) to amend the health standards for formaldehyde impact, for the time being difficult to predict. The announcement is based on an assessment of the health risks exposure of workers. Elkins, director of the Office of Poisons for the EPA, said the agency must now determine whether it is necessary to manage its operations in accordance with the toxicological rules and that the OHSA is now seeking to control the touch of formaldehyde in the workshop and reconsider the current standard for amending the chemical. OSHA recommends that the exposure threshold be reduced from the current 3 ppm to 1 or 1.5 ppm. Elkins said that despite the announcement that formaldehyde is a suspicious human carcinogen, there are still some doubts about the underlying data. Therefore, the need to control the use of formaldehyde, need further consideration. The EPA combines 28 epidemiological surveys, of which 9 are timber
