The majority of hydrogen chloride is believed to deposit rapidly to soil and water by wet and dry deposition or attach to particles in the atmosphere (Sanhueza, 2001). Because of their high solubility in water, acid gas vapors can readily deposit[r]

Symptoms of some diseases such as asthma, hyper-sensitivity, pneumonitis and humidifier fever may appear[r]

For instance, Australian researchers found that for biodiesel production, palm oil can produce up to an 80 percent saving in emissions, provided it is sourced from older plantations, rather than from plantations cleared from forested areas (Beer et al., 2007). And sometimes it is not an energy crop[r]

Therefore firms and inhabitants of China will gain from more economic regulation of the environment Current economic regulation in China i[r]

Studies. The quality of ambient air depends upon the concentrations of specific contaminants, the emission sources and meteorological conditions. The mining activities contribute to the problem of air pollution directly or indirectly (Trichy ,1996, Corti and Senatore, 2000, Baldauf et[r]

(HAPs)HAPs, also known as toxic air pollutants or “air toxics” in the USA, are those pollutants that are known or suspected to cause cancer or other serious health effects. A large number of HAPs are found in urban air. HAPs are difcult to manage due their low con[r]

By 1987 the depletion of the ozone layerhad become so problematic that most industrial na-tions met in Montreal to ratify an international treatycalling for immediate reductions in all CFC use with acomplete phase-out by the year 2000.[r]
