Groundwater pollution prevention and control should be given priority to avoid costly remediation since groundwater pollution is invisible, complex, and has long-term impact. Groundwater pollution risk assessment, which refers to the process of determining potential impacts of any pollutant, is an...

Background: Limited studies have examined the association between air pollutants and osteoporosis incidence; however, the results are conflicting. We aimed to quantify the effects of selected air pollutants on osteoporosis risk and explore the modifying effect of genetic predisposition. Methods: A...

Modeling fine-scale spatial and temporal patterns of air pollutants can be challenging. Advanced spatio-temporal modeling methods were used to predict both long-term and short-term concentrations of six criteria air pollutants (particulate matter with aerodynamic diameter less than or equal to 10...

In this paper, an improved mathematical model is proposed to analyze a special internal relationship between rainfall intensity and gas pollutants in urban atmospheric system, where the nonlinear relationship between precipitation and the concentration of pollutants in the air is considered, as...

Based on a typical residential area, this paper studies the characteristics of pollutant concentration changes in two rainfall runoffs and the first flush effect of rainfall. In rainfall runoff, the concentrations of seven pollutants (COD_Mn, TN, DTN, NH₃-N, TP, DTP, and PO_4^3-) increased during the...

The chapter elaborates on the analysis of groundwater hydro-chemical characteristic, assessing the groundwater quality and groundwater pollution according to the groundwater quality data collected in the 2005 and judging the sources of groundwater pollution according to the distribution of land...

With a case from Jilin section of the Songhua River, this study applies the overlay index method to assess the shallow groundwater pollution risk and the "concentration-loss" model to calculate economic losses of groundwater pollution, covering a variety of pollutants from different sources, and on ...

Organic phenolic pollutants in industrial wastewater cause severe environmental pollution and physiological damage. Poly (N-isopropylacrylamide) (PNIPAM) hydrogels generally have poor mechanical strength and are also intrinsically frangible, limiting their widespread applications in wastewater...

A three-dimensional traffic geometry model consisting of a traffic roundabout, tunnel, viaduct, and a sinking bus station was built, and the mathematical model by coupling the fluid flow and pollutant propagation in this system was established. The fluid and gaseous pollutant flowing in this system ...

Groundwater pollution risk assessment is the premise and foundation of groundwater pollution prevention and control. In order to make new breakthrough, groundwater pollution risk assessment should be combined with economic analysis to carry on environmental protection and management of groundwater. ...
