Air Pollution Processing by Radiation Fogs
Several fog episodes occurred in California’s San Joaquin Valley during winter 2000/2001. Measurements revealed the fogs to generally be less than 50 m deep, but to contain high liquid water contents (frequently exceeding 200 mg/m) and large droplets. The composition of the fog water was dominated by ammonium (median concentration= 608 μN), nitrate (304 μN), and organic carbon (6.9 ppmC), with ...
متن کاملProcessing of atmospheric organic matter by California radiation fogs
Considerable effort has been put into characterizing the ionic composition of fogs and clouds over the past twenty-five years. Recently it has become evident that clouds and fogs often contain large concentrations of organic material as well. Here we report findings from a series of studies examining the organic composition of radiation fogs in central California. Organic compounds in these fog...
متن کاملChinese Growth and Atmospheric Pollution:
This paper uses a dynamic CGE model, calibrated to new and detailed Chinese emissions data, to assess two important questions. What can we reasonably expect Chinese emissions trends to look like over the next two decades? Secondly, what would be the appropriate policy interventions to flatten Chinese emissions trajectories and reduce the risk of local, regional, and even global adversity? This ...
متن کاملAtmospheric pollution and lung cancer.
Lung cancer is consistently more common in urban areas than in rural. The excess cannot be accounted for by specific occupational hazards but some of it might be due to the presence of carcinogens in urban air. The excess cannot be wholly due to such agents, because the excess in nonsmokers is small and variable. Cigarette consumption has also been greater in urban areas, but it is difficult to...
متن کاملEnvironmental Management & Pollution SECONDARY ATMOSPHERIC POLLUTION
4.2 Acid Deposition Acid rain was first identified in the 19th century, when English pharmacist Robert Angus Smith measured high acidity levels in rain falling over industrial regions of England and much lower levels in less-polluted areas near the coast. However, this pattern did not receive sustained attention until biologists began to notice sharp declines in fish populations in lakes in Nor...
