Special Issue Information

Dear Colleagues,

With the rapid development of modern industry, soil heavy metal pollution has gradually become a global environmental problem. Heavy metal pollution in soil has the characteristics of concealment, hysteresis, accumulation, and irreversibility, which greatly increase the difficulty of monitoring and treating heavy metal pollution in soil. Heavy metal pollution will have an important impact on soil microbial communities, soil enzyme activities, and soil biochemical processes, and then affect human health and the balance of soil ecosystems. A comprehensive understanding of the consequences and underlying mechanisms of heavy metal pollutants, as well as the response of and changes in soil ecology in the process of heavy metal pollution in soil, is of great significance to the development of the effective remediation and treatment of soil heavy metal pollution.

This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) focuses on the most recent developments in the links between heavy metal pollutants and soil ecology, including the impacts and mechanisms of pollutants on the soil environment, the effects of heavy metal pollution on soil–plant systems, the monitoring and remediation of heavy metal pollution, etc. New research papers, reviews, and short communications are welcome to this Special Issue. Papers involving the development of new methods for the risk assessment and management of heavy metal pollution will also be accepted. In addition, studies referring to the development of policies for the protection and restoration of soil quality against heavy metal pollutants are also welcomed in this Special Issue.

The aim of this study was to assess the total concentration and speciation variation of heavy metals (Pb, Cd, Cu and Zn) during composting and vermicomposting of industrial sludge with different addition rations of rice husk biochar. Results indicated that pH, EC, total phosphorus (TP) and total potassium (TK) were increased and total organic carbon (TOC) and total nitrogen (TN) were decreased during the composting of industrial sludge with biochar compared with the control (sludge without biochar). The addition of earthworm to the biochar-amended sludge further decreased pH and TOC but highly enhanced the EC, TN, TP and TK. Comparatively lower concentrations of total and DTPA-extractable heavy metals were observed in biochar-amended sludge treatments mixed with earthworm in comparison with the biochar-amended sludge treatments without earthworm or the control. Sequential extraction methods demonstrated that vermicomposting of sludge with biochar converted more metals bound with exchangeable, carbonate and organic matter into the residual fraction in comparison with those composting treatments of sludge with biochar. As a result, the combination of rice husk biochar and earthworm accelerated the passivation of heavy metals in industrial sludge during vermicomposting. Rice husk biochar and earthworm can play a positive role in sequestering the metals during the treatment of industrial sludge. This research proposed a potential method to dispose the heavy metals in industrial sludge to transform waste into resource utilization. Full article
