Special Issue Information

Dear Colleagues,

Industrial and agricultural pollution represent a global environmental problem. The environmental issues of contaminated industrial and agricultural sites and surrounding areas include air pollution, erosion, a loss of biodiversity, and the pollution of soil and surface water/groundwater caused by chemicals used in industrial and agricultural processes. Therefore, it is important to address these issues and minimize the related health risks to local populations and communities. However, research investigating, evaluating, and controlling water–soil pollution is still lacking or in its early stages.

Irrigation agriculture is increasing to improve crop productivity in polluted, arid areas. The current research mainly focuses on water quality investigation and risk assessment, also proposing governance strategies. However, in many places where polluted water is used for irrigation, research on these issues has not yet reached clear conclusions. Further research is needed to develop irrigation water quality standards and to evaluate the degree of pollution after irrigation in polluted areas.

The scope of this research topic is to discuss the migration and transformation characteristics (or mechanisms) of industrial and agricultural pollutants in soil and water, as well as conduct a risk assessment of these pollutants. It will also include theories of water–soil pollution control, remediation methods, and improved governance technologies.The areas covered by this research topic may include, but are not limited to, the following:

(1) Migration and transformation of pollutants in "water–soil–plant";

(2)Water–soil risk assessment;

(3)Water–soil treatment and remediation technology;

(4)Advanced oxidation;

(5) Membrane separation;

(6) Resource utilization;

(7)Toxins and toxicology;

(8) Food safety.

In order to solve the problem of the low treatment efficiency of wastewater containing heavy metals in mining areas, straw biochar and graphene oxide enhanced external pressure ultrafiltration (SGU) was used to treat wastewater containing high concentrations of Pb2+. The operation parameters such as pH and temperature were optimized, and the removal efficiency of CODCr, NH3-N, turbidity and Pb2+ via SGU, straw biochar ultrafiltration (SU), ultrafiltration (UF), and conventional treatment (CT) were systematically investigated. The results showed that the pH and temperature of polluted water were 4.8–5.2 and 21–30 °C, respectively, the average removal rates of CODCr, NH3-N, turbidity and Pb2+ by SGU reached 91%, 97%, 98% and 95%, respectively, and the removal effect was better than that of other processes. In addition, under the backwash conditions of clean water, weak acid, and weak alkali, the membrane flux recovered 65%, 88%, and 89% of the new membrane, respectively. This study provides scientific and theoretical support for the advanced treatment of polluted water in mining areas. Full article
