Johnson said photochemical oxidant pollution occurs under entirely different conditions from carbon monoxide pollution because it is formed in the atmosphere...
...problems encountered in coal liquefaction may seem to the layman to justify the granting of government subsidies. The process requires the introduction of large amounts of hydrogen to coal at high temperatures and under very great pressure: it results in a rough equalization of the ratios of hydrogen and carbon molecules in coal. Frederich Bergius developed the process for turning coal into crude oil in Germany in 1913, and Franz Fischer and Hans Tropsch devised a catalytic process for converting coal directly into gasoline in 1925. During World War II the Bergius and Fischer-Tropsch processes supplied the Nazi government...
...opens in 1978 because of stricter government controls on auto pollution. President Ford, however, has asked recently that the implementation of laws requiring new emission control devices be delayed to conserve gasoline use. If his proposal is adopted, the library will increase air pollution in an area that has carbon monoxide levels presently in excess of federal standards 60 to 70 per cent of the time...
...objective of the impact analysis was to evaluate the maximum carbon monoxide levels which could arise as a consequence of both adverse meteorological conditions and peak roadway traffic. Although motor vehicles are also major contributors to community nitrogen oxides and reactive hydrocarbon emissions, these species participate in a series of complex photochemical reactions for which the current atmospheric diffusion modeling technology does not permit preparation of reliable estimates of projected concentration levels. Therefore, emphasis was placed principally on carbon monoxide concentration levels as this pollutant is relatively inert. In addition, carbon monoxide is the pollutant emitted in the largest quantities...
...cases, predicted carbon monoxide levels will be within air quality standards established by the State and Federal Authorities. The small incremental increase in traffic induced by the project will have an insignificant effect on the attainment and maintenance of such standards. Thus, the project is consistent with the State Implementation Plan developed to insure the attainment of air quality standards required under the Federal Clean...
