After the exposure data are obtained, it is necessary to compare actual exposure levels to acceptable occupational health standards, such as TLVs, PELs, or IDLH concentrations. These standards together with the actual concentrations are used to identify the potential hazards requiring better or more control measures.

Although epidemiological data provide the strongest evidence that specific chemicals affect human health, occupational exposure limits and other preventive measures typically are not based on these types of data alone. The number of chemicals to which workers are exposed far exceeds the number of solid epidemiological studies. Therefore, many occupational health standards and protective health measures are based on data from toxicology studies. Consequently, one of the major challenges that faces an occupational toxicologist is how to interpret the results obtained from animal studies and molecular studies for application to humans.

Factors which are important for the lowering of human health risks due to mineral deficiency and intoxication are the normative requirements of the macro, trace and ultratrace elements, recommendations for their intake, their apparent absorption and excretion rates, their interactions, tolerance limits for chemicals in food and water, and occupational health standards. 

In 1974, NIOSH (which is responsible for recommending health and safety standards) joined OSHA (whose jurisdictions include promulgation and enforcement activities) in developing a series of occupational health standards for substances with existing PELs.

At present our country is still more than most of the coal mining face dust concentration national occupational health standards, a serious threat to the miners health. Dust is mainly through the respiratory tract and skin penetration into the body, pneumoconiosis disease of coal miners as occupational diseases. 

In coal mine system, major noises come from main fans, coal winning machines, transport machines, road-headers, air hammers, electric drills, trolleys, cages, air compressors and auxiliary fans, etc. Because underground working space is small and closed in coal mines, it is difficult for the sound to spread and due to hard walls around tunnel, sound-absorbing ability is not obvious, which makes the underground noise pollution more serious in coal mines (Ye 2005). Statistics show that noise intensity among many coal mines reach and even exceed the national occupational health standards (Xu Liu 2008).

NIOSH was created in 1970 by the OSHAct and established in the Department of Health Education and Welfare, which became the Department of Health and Human Services, to carry out the duties of the OSHAct assigned to the secretary of health and httman services. Those duties include research, experiments, and demonstrations related to occupational safety and health (Ptrblic Law 91-596). NIOSH first published its Criteria for a Recommended Standard Occupational Exposure to Inorganic Lead in 1973. After an OSHA proposal to revise the occupational health standard for inorganic lead in 1976, NIOSH revised its criteria document in 1978 and lowered its recommended 10-hotrr TWA for airborne lead from 150 to 100 pg/m and its recommended maximum BLL from 80 to 60 pg/dL (NIOSH 1978). 

The eight-hour time-weighted average concentration specified for workroom air selected from the 1986-1987 Threshold Limit Values and Biological Exposure Indices as adopted by the American Conference of Governmental Indnstrial Hygienists the Recommended Standards for Occnpational Exposme set forth in the July 1985 summary of the National Institnte for Occnpational Safety and Health Recommendations for Occupational Health Standards or the 1986 Workplace Environmental Exposure Levels set forth by the American Indnstrial Hygiene Association. 

The primary purpose of the Occupational Safety and Health Act of 1970 is to assure, so far as possible, safe and healthful working conditions for every working man and woman. The interim final occupational health standard for lead in construction is designed to protect workers exposed to inorganic lead including metallic lead, all inorganic lead compounds and organic lead soaps.

Chemical Hazards. OSHA currently has no occupational health standards for laser products. Threshold limits established by the American Conference of Governmental Industrial Hygienists are the recommended values to use. All laser products should meet specifications of the National Electrical Code (NFPA 70-1981), Arts. 300 and 400. Adherence to control procedures required under this standard should eliminate any significant probability of detrimental health effects from laser product operations. Therefore, an extensive, medical surveillance protocol for laser operators is not required under this standard.
