6) health effects of fluorine pollution 氟污染对健康的影响补充资料:二氧化硫污染对健康的影响 二氧化硫 (SO2)是一种常见的和危害较大的大气污染物。在五种主要大气污染物(一氧化碳、二氧化硫、碳氢化物、飘尘、氮氧化物)中,它的含量约占15%。二氧化硫形成对人类健康有害的硫酸雾有两种过程:一是二氧化硫遇水...
And SO 2 is a precursor for sulfuric acid, an air pollutant that plays a major role in the adverse respiratory effects of air pollution. This chapter summarizes what is known about the health effects of both SO 2 and sulfuric acid through a review of controlled and epidemiologic studies....
Exposure to concentrations of 10 to 50 ppm for 5 to 15 min causes irritation of the eyes, nose, and throat, choking, and coughing. Some individuals are extremely sensitive to the effects of sulfur dioxide, while experienced workers may become adapted to its irritating properties. Sulfur dioxide...
Sulfur dioxide and nitrogen dioxide levels inside and outside homes and the implications on health effects research 来自 ACS 喜欢 0 阅读量: 58 作者:JD Spengler,BG Ferris,DW Dockery,FE Speizer 摘要: This paper presents the results of 1 year's indoor and outdoor monitoring for SO2 and NO2 ...
The scientific literature on the health effects of nitrogen dioxide (NO) and sulfur dioxide (SO) were reviewed with particular focus on the chemical and physical properties of the 2 gases and the toxicological characteristics identified in animal studies at exposure concentrations near the rate of am...
In the 1970s, pest resistance emerged which, combined with influence of the book “Silent Spring”, and accumulated evidence on the effects of pesticides, culminated in banning of the use of DDT in the United States in 1972. Thereafter, other countries discontinued the use of DDT, as well ...
The list of the main engine exhaust pollutants linked to adverse health effects includes: Particulate matter (PM) Hydrocarbons (HC) Carbon monoxide (CO) Nitrogen oxides (NOx) Sulfur dioxide (SO2) Among these compounds, PM, HC, CO and NOx (i.e., NO + NO2) are regulated engine emissions....
Adding VitC to a CHX-containing mouthwash may allow for the beneficial effects of VitC on oral and periodontal health. Chlorhexidine gluconate 0.05% combined with ascorbic acid (vitamin C) was reported to be statistically effective in maintaining low levels of volatile sulfur compounds compared to ...
The results indicate that respiratory problems are correlated significantly with pollution levels, especially sulfur dioxide from the local trash-to-energy incinerator—the fifth largest one in the U.S. The effects of a given pollution level tend to be more serious for specific subgroups based upon...
In addition, a number of studies examining the effects of ambient level exposure to NO 2 , SO 2 , and CO have failed to find associations with adverse health outcomes. 展开 关键词: air pollution health respiratory tract diseases cardiovascular diseases nitrogen dioxide sulfur dioxide carbon ...
