Water pollution compensation is one of the important economic means of water pollution control and management, and the quantification of compensation standard is the key link in the implementation of water pollution ecological compensation. Because the ecological compensation refers to ecological...

Previous studies have suggested a change of birth weight linked with elevated ambient air pollutant concentrations during the pregnancy. However, investigations of the influence of higher pollutant levels on birth weight change are limited. The goal of this study is to evaluate whether the air ...

Biochar has been widely applied in soil remediation and water pollution control due to its high stability, excellent surface properties, high-developed pore structure and rich surface functional groups. In this paper, the research progress of biochar application to treatment of various pollutants...

Haze pollution is inseparable from the transformation of air pollutants especially the ammonium and sulfate. Chemical and physical processes play important roles in this transformation. However, the role of microbial processes has rarely been studied. In this report, we applied the...

Agricultural nonpoint source (NPS) pollution has become one of the major contributors to water quality degradation. It is of great significance to identify the spatial-temporal distribution and output characteristics of agricultural NPS pollution, and to explore the mitigation methods in typical...

During embryogenesis and embryo implantation, the copy number of mtDNA is elaborately regulated to meet the cellular demand for division, growth and differentiation. With large numbers of mitochondria for energy production, placental cells possess strong endocrine functionalities and capacities for ...

Degrading aquatic organic pollutants efficiently is very important but strongly relied on the design of photocatalysts. Porous graphene could increase photocatalytic performance of ZnO nanoparticles by promoting the effective charge separation of electron-hole pairs if they can be composited....

Molecularly imprinted polymers (MIPs) have been widely used in the field of environmental engineering, but the traditional MIPs are still not green because large quantities of organic porogen and hazardous functional monomers are required during the preparation process. To overcome these...

Accumulating evidences indicated that heavy metals may disrupt human sex hormones. However, the combined effects of heavy metals on sex hormones remain to be clarified. To explore the independent and combined associations between heavy metal exposure and serum sex hormones among adults, data of...

Using a referendum-format contingent valuation survey, we investigated the residents' willingness to pay for restoring the water quality of the Paraíba do Sul river in the city of Campos dos Goytacazes, Brazil. We estimated values for an environmental improvement consistent with the Brazilian water ...
