Exposure of mice with emphysema to CS exacerbated the pulmonary damage, and NAC reduced the CS-mediated pulmonary damage by preventing oxidative damage and reducing inflammatory responses.

Based on the distribution of sulfate in groundwater of Jiaozuo Area, pollution sources can influence the groundwater were analyzed. The results show that sulfate pollution in groundwater of Jiaozuo Area is serious; industrial pollution is the main reason for sulfate pollution in groundwater; sewage irrigation and overcommitting fertilizers are the important reason for the sulfate pollution in groundwater; mine drainage and the overexploitation of groundwater can accelerate the sulfate pollution in groundwater.

We set the karst fissure water where a oil refinery is located as a study object. Quantitative method of vulnerability analysis is raised for petroleum hydrocarbon contamination groundwater system in multiple factor combination conditions.We established the ANN model structure depending on the selected evaluation factors and obtained the weight of each factor coefficient, then superposed the weights of each factor thematic layer by applying ANN and GIS,and put forward model system of vulnerability analysis which petroleum hydrocarbon contaminate groundwater aquifer. Spatial distribution of antifouling performance is finally achieved of which groundwater aquifer is polluted by petroleum hydrocarbon.
