Secondary Pollution in the Environmental Pollution Control Process: Production, Environmental Risks and Reduction

About this Research Topic

To meet increasingly stringent regulations, large-scale controls on devices for either air pollutant control or wastewater treatment have been implemented at the source of production to reduce the emission of environmental pollutants. However, during device operation secondary pollutants are frequently produced presenting a challenge for mature technologies. Evaluation of secondary pollution and the control strategies used in the process of pollution control have practical significance in minimizing environmental risk and improving current technologies.

Converting pollutants into harmless products is a major task for environmental pollution control. However, inappropriate conversions usually occur in the control process, which produce more toxic byproducts than the original pollutants. Examples include the conversion of NO to N2O in the selective catalytic reduction (SCR) process, the condensation of chlorinated organics into polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in heterogeneously catalytic reactions, and disinfection byproducts produced from the wastewater treatment process. Although the production of secondary pollutants in the control process has been recognized, assessing the environmental risk and the development of compliant control technologies is still insufficient as knowledge of the underlying mechanism of secondary pollution generation in many mature technologies is lacking.

This Research Topic aims to bring together catalytic chemists, environmental chemists, material scientists, chemical engineers and industrial chemists working in the field of the abatement of secondary pollutants. Original Research and Review articles are welcomed, and potential themes include, but are not limited to, the following:

• CO oxidation
• NOx abatement
• Volatile organic compounds (VOCs) abatement including air and aqueous pollutants
• Wastewater treatment including activated sludge and biofilm processes
• Soil pollution remediation

Topic Editor Dr Fudong Liu (University of Central Florida) holds patents relating to the catalytic reduction of NOx. All other Topic Editors declare no competing interests with regard to the Research Topic subject


Keywords: Secondary pollution, environmental remediation, catalytic reduction, soil pollution, wastewater treatment, volatile organic compounds


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
