In the context of the national strategy of high-quality development of the Yellow River Basin, studying the distribution characteristics, environmental behavior and the ecological risks of emerging pollutants in the sediments of the Yellow River Basin is an important basis for improving the ...

Air pollution is associated with stroke, but few previous studies have explored the impact of exposure to a sustained high air pollution level (which we define as an air pollution wave) on stroke. We decomposed the effect estimates of air pollution waves into a main effect estimate and an added...

Based on the input-output analysis(IOA) and structure decomposition analysis(SDA) model, this article systematically identified the factors affecting the discharge of chemical oxygen demand(COD) and ammonia nitrogen during the period from 2010 to 2015, which are the effects of concentration of the ...

In-situ burning can be used to prevent oil spreading in oil spill response. In this study, a steady-state Gaussian plume model was applied to analyze the concentration distribution of fine particulate matter produced by in-situ burning, as well as to assess the health risks associated with...

As an environmentally friendly and promising semiconductor, graphitic carbon nitride (g-C₃N₄) was widely used in photocatalytic treatment of aqueous organic pollutants. In this study, cobalt-to-oxygen doped graphitic carbon nitride with feeble nitrogen vacancies (Co-OCN_VN) as metal-to-ligand charge ...

Intensive anthropogenic activity has triggered serious heavy metal contamination of soil. Land use and land cover (LULC) changes bear significant impacts, either directly or indirectly, on the distribution of heavy metal in soils. A total of 180 samples were acquired from various land covers at...

Studying the characteristics of new particle formation (NPF) is conducive to exploring the impact of atmospheric particulate matter on the climate, environment, and human health. The particle number size distributions (5.6-560 nm) of aerosols were measured using a fast mobility particle sizer...

Mass concentrations of chemical compounds in both PM_2.5 (particle aerodynamic diameter, Dp <2.5 µm) and PM_2.5-10 (2.5 < Dp <10 µm), and acidity of aerosol particles were measured at an urban site in western Japan using a continuous dichotomous Aerosol Chemical Speciation Analyzer (ACSA-12) throughout 2014. Mass concentrations of both PM_2.5 and sulfate had distinct seasonal variabilities with maxima in spring and winter, mostly due to long-range transport with the prevailing westerly wind. Mass concentration of nitrate in PM_2.5...

Monitoring of the environmental exposure level of emerging pollutants (EPs) is an important way to ascertain the pollution condition and control the risks of EPs. Developed countries and regions have established survey and monitoring system for EPs under the framework of chemical environmental...

Asia is one of the fastest-growing regions in international tourism, economic growth, and CO2 emissions around the globe. However, the relationships between tourism and CO₂ emissions are little and unclearly identified. The purpose of the study is to explore the asymmetric nexus between tourism and ...
