Impact on Eye Health Regarding Gaseous and Particulate Pollutants

Gaseous pollutants in particulate matter epidemiology: confounders or surrogates?

Air pollution epidemiologic studies use ambient pollutant concentrations as surrogates of personal exposure. Strong correlations among numerous ambient pollutant concentrations, however, have made it difficult to determine the relative contribution of each pollutant to a given health outcome and have led to criticism that health effect estimates for particulate matter may be biased due to confo...

Short-term effects of ambient gaseous pollutants and particulate matter on daily mortality in Shanghai, China.

Identification of the specific pollutants contributing most to the health hazard of the air pollution mixture may have important implications for environmental and social policies. In the current study, we conducted a time-series analysis to examine the specific effects of major air pollutants [particulate matter less than 10 microns in diameter (PM(10)), sulfur dioxide (SO(2)), and nitrogen di...

Impacts of a nanosized ceria additive on diesel engine emissions of particulate and gaseous pollutants.

Fuel additives incorporating nanosized ceria have been increasingly used in diesel engines as combustion promoters. However, few studies have assessed the impact of these nanotechnology-based additives on pollutant emissions. Here, we systematically compare emission rates of particulate and gaseous pollutants from a single-cylinder, four-cycle diesel engine using fuel mixes containing nanoceria...

Adsorption of Gaseous Pollutants

Interaction of gaseous and particulate pollutants in the respiratory tract: mechanisms and modulators.

Human contact with air pollution usually involves exposure to more than one chemical, and biological responses to the inhalation of polluted atmospheres likely depend upon the interplay between individual materials. Thus, characterizing effects from exposures to mixtures of air pollutants is necessary for adequate quantitation of health risks. Exposure to gas/particle mixtures may result in res...
