In the context of increasing urbanization and worsening environmental pollution, nonpoint source pollution during high-frequency rainfall has become a major ecological problem that endangers residents in cities. This study takes Shenzhen as an example. On basis large number soil sample test data, combined with relevant variables, it drawn high-resolution, high-precision spatial distribution map...

Currently, the treatment of point source pollution has been basically com-pleted, and development non-point pollution(NPP) become a new threat to natural water. Unlike pollution, NPP is much more complex than in terms difficulty measures. Therefore, gradually focus researchers’ attention. This paper mainly reviews current research status on governance NPP, precisely urban agricultural governanc...

the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

Agricultural non-point source (NPS) pollution poses a severe threat to water quality and aquatic ecosystems. In response, tremendous efforts have been directed toward reducing these pollution inputs by implementing agricultural conservation practices. Although conservation practices reduce pollution inputs from individual fields, scaling pollution control benefits up to the watershed level (i.e...

The control of agricultural non-point source pollution, especially the problem planting is great significance to comprehensively promote rural revitalization. First, based on panel data from 2006 2020 and using DID model 30 provinces were classified in China. It found that environmental protection policies have a significant inhibitory effect pollution industry, more obvious over time. From per...

Thank you Admiral Watkins and commission members for allowing me this opportunity to draw your attention to two recent reports of the National Academies that address what are arguably two of the most significant challenges to coastal and marine environmental quality: oil pollution and nutrient pollution. A decade ago public concerns about marine pollution were driven by the dramatic footage fro...

BACKGROUND Certain subgroups in the general population, such as persons with existing cardiovascular or respiratory disease, may be more likely to experience adverse health effects from air pollution. METHODS In this European multicenter study, 25,006 myocardial infarction (MI) survivors in 5 cities were recruited from 1992 to 2002 via registers, and daily mortality was followed for 6 to 12 y...

The uncertainty of water quality predictions caused by uncertainty in the inputs related to emissions of diffuse pollution is analysed. An uncertainty analysis of the effects of diffuse pollution is essential to compare the cost and benefits of measures to lower those emissions. We focus on diffuse nitrate pollution due to fertiliser use. Using an efficient Monte Carlo method and Latin Hypercub...

BACKGROUND Both air pollution exposure and socioeconomic status (SES) are important indicators of children's health. Using highly resolved modeled predictive surfaces, we examine the joint effects of air pollution exposure and measures of SES in a population level analysis of pregnancy outcomes in North Carolina (NC). METHODS Daily measurements of particulate matter <2.5 μm in aerodynamic dia...
