The provinces of China have suffered from severe PM2.5 pollution in recent years, presenting a significant threat to human health. Identifying associations between mortality rate and PM2.5 level is extremely useful for a range of purposes, such as the development of preventive measures, increasing health awareness, and establishing disaster warning systems. Based on remote sensing data, station monitoring...
In this study we investigated the role of NO in Pb-induced yeast cell death. We found that the rate of cell death increased with increasing concentrations of Pb(NO₃)₂ and prolonged exposure to Pb(NO₃)₂. NO production also increased significantly during Pb-induced yeast cell death. An exogenous NO donor increased Pb toxicity to cells, while NO synthesis inhibitors and NO-specific scavengers alleviated...
Near-infrared spectroscopy (NIRS) can detect soil total phosphorus in agricultural environments. Considering the soil moisture and particle size on total phosphorus prediction, we applied NIRS to the detection of soil samples with different soil moistures and particle sizes. Thus the effect of soil moisture and particle size was analyzed quantitatively and qualitatively. The procedures to remove the...
Considering the characteristics of rural domestic sewage in central China, an unpowered complex ecotechnology composed of anaerobic baffled reactor (ABR), composite soil filling (CSF) system, and free water surface (FWS) constructed wetland was developed to treat rural sewage. The Guogang Village sewage treatment demonstration project at Xinmi City showed that the complex ecosystem had remarkable...
