From International Labour Office (1991) US Occupational Safety and Health Administration (OSHA) (1996) American Conference of Governmental Industrial Hygienists (ACGIH) (1997a,b) US National Library of Medicine (1997b) Deutsche Forschungsgemeinschaft (1998) Ministry of Social Affairs and Health (1998)... 

The US Occupational Safety and Health Administration (OSHA) permissible exposure limits for hydrogen sulfide is 10 ppm (time weighted average) for an eight-hour exposure and 15 ppm (shortterm exposure limit). The transitional limits are 20 ppm (ceiling) and 50 ppm (peak - ten-minute exposure). 

Other data sets, with a broader coverage of jobs throughout the population, are likely to be needed for estimation of pesticide exposures in case-control studies. For example, Stewart and co-workers (Stewart and Stewart, 1994 Stewart et al, 1998) have used detailed occupational questionnaires with job-specific modules, together with data from the US Occupational Safety and Health Administration (OSHA) Integrated Management Information System to aid in assigning study subjects exposures to multiple chemicals, including pesticides. 

The GHS applies to pure chemical substances, their dilute solutions and to mixtures of chemical substances. Articles as defined in the Hazard Communication Standard (29 CFR 1910.1200) of the US Occupational Safety and Health Administration, or by similar definition, are outside the scope of the system. 

While the acceptable blood lead level set by the US Occupational Safety and Health Agency (OSHA) remained 50 //g/dL in 2007, that for children had been progressively lowered by the Center for Disease Control and Prevention (CDC) to 10 /(g/ dL by 1991. The disparity between acceptable blood lead levels in adults and children can be explained in part by the paucity of studies of lead toxicity in adults, and the increased sensitivity of the developing brain in children to toxins. The efforts of the lead industry to thwart public health regulation in the workplace contributed to the disparity in standards for children and adults. OSHA is reluctant to revise the occupational lead standard because of the risk of litigation. The mounting evidence of the impact of lower and lower lead levels on blood pressure and the kidneys in industry and the general public is reviewed in this chapter. 

Benz [a] anthracene alone is not regulated however, all polycyclic aromatic hydrocarbons or volatile coal tar products together are regulated. The World Health Organization has established 0.2 pgH as the limit for aromatic hydrocarbons in a domestic water supply. The US Occupational Safety and Health Administration limit in workplace air (coal tar volatiles) is 0.2 mg m The US Environmental Protection Agency weight-of-evidence classification for benz [a] anthracene is B2, a probable human carcinogen, for both oral and inhalation exposure based on adequate animal evidence and no human evidence. 

The American Conference of Governmental Industrial Hygienists threshold limit value (time-weighted average) is 50 ppm (246 mg m ) based on irritation and CNS depression. The (US) Occupational Safety and Health Administration permissible exposure limit, (US) National Institute for Occupational... 

The US Occupational Safety and Health Administration regulatory level in workplace air is 1 ppm for an 8 h day, 40 h week. US Environmental Protection Agency has set a limit in water of 0.005 mg 1 The US National Institute for Occupational Safety and Health recommends that it would be prudent to handle 1,2-dichloroethane in the workplace as if it was a human carcinogen. 

The US Occupational Safety and Health Administration permissible exposure limit is 0.1 ppm time-weighted average (TWA). 

NSF International is a not-for-profit, nongovernmental organization that is known world wide for standards development and product certification. NSF is accredited by ANSI, US Occupational Safety and Health Administration (OSHA) and the Standard Council of Canada (SCC). Water program standards important to drinking water quality in the United States include the following ...
