U.S. regulations for environmental contaminants have generally fallen in the 10-4 to 10-6 lifetime risk range, as calculated from a relatively worst-case linear multistage model. Most of those decisions incorporated consideration of costs and feasibility. 

In practice, the classical analytical methods used to assess the degree of environmental pollution are intended for the determination of only a limited number of chemical compounds (or groups of compounds), that is, those whose presence in the environment and permitted levels of concentration are regulated for environmental protection. Present legal regulations do not take the following into account3 ...

This section gives a nonexhaustive overview of the regulatory state of the art on human risk assessment of chemical mixtures in the United States, the European Union (EU), and other nations and (international agencies. The focus is on regulations for environmental pollution, but when available and relevant, mixture regulations from other policy areas have also been included in the overview, for example, for food quality and the workplace. The reader is referred to McCarty and Borgert (2006) and Monosson (2005) for a more extensive overview of mixture toxicity regulations related to human health.

There is also, however, an increasing resistance by local communities to siting new plants in many of these European areas. Moreover, the environmental regulations have become increasingly stringent in Germany, the Netherlands, and Erance. It is estimated that the environment and other safety-related costs in Germany have risen to the point where 30% of the total capital investment needed is for environmental and safety measures.

As a result of this oversupply, scrap values for many recyclable materials have fallen noticeably over the past few years. Further complicating matters are new efforts from regulators and environmental activists to mandate the reuse of certain materials (rates and dates) and that products be made with specified amounts of recycled material (product content laws). Such demand-side measures distort market forces and do not appear to be justified on either economic or environmental grounds. 

Trichloroethylene use has declined as a result of environmental concerns. However, trichloroethylene may replace some 1,1,1-trichloroethane appHcations. Perchloroethylene used in small businesses for dry cleaning will be regulated for emissions under the same guidelines as those that govern the large chemical producers. This will cause replacement of perchloroethylene for those appHcations where recovery is uneconomical. Methylene chloride has been classified as a suspected carcinogen and its use will decline in aerosol and paint stripping appHcations because of health concerns.

U.S. Environmental Protection Agency regulations for commercial, jet, and turbine-powered aircraft (3) are based on engine size (thrust) and pressure ratio (compressor outlet/compressor inlet) for the time in each mode of a standardized takeoff and landing cycle. Once the aircraft exceeds an altitude of 914 m, no regulations apply.

The chemical and solvent processes previously discussed remove acid ga from the gas stream but result in a release of H2S and CO2 when the solvent is regenerated. The release of H2S to the atmosphere may be limited by environmental regulations. The acid gases could be routed to an incinerator or flare, w hich would convert the HiS to SO2. The allowable rate of SO2 release to the atmosphere may also be limited by environmental regulations. For example, currently the Texas Air Control Board generally limits H2S emissions to 4 Ib/hr (17.5 tons/year) and SO2 emissions to 25 tons/year. There are many specific restrictions on these limits, and the allowable limits are revised periodically. In any case, env ironmental regulations severely restrict the amount of H S that can be vented or flared in the regeneration cycle.
