Emerging organic pollutants refer to the pollutants caused by human activities, which exist but cannot be regulated by laws, and can endanger life and the ecological environment, including endocrine disruptors (EDCs), perfluorinated compounds (PFCs), drinking water disinfection by-products (DBPs), organophosphate esters (OPEs), etc. The environmental pollution of these emerging organic pollutants has become a major environmental problem facing the world.
The estuarine environment is an important link connecting land rivers and marine water bodies and also the typical zone of land-sea interaction. It is characterized by strong hydrodynamic action, frequent sediment transport and material exchange, complex multi-material and multi-interface interaction, and large gradient changes in physical and chemical factors. At the same time, the estuary is also an important channel for land-based pollutants to enter the sea. After the land-based pollutants enter the estuary environment where the hydrochemical conditions such as pH, salinity, dissolved organic matter and redox potential change sharply, they will undergo various chemical processes such as coagulation, precipitation, adsorption and desorption, which will affect the migration and transformation of pollutants in the estuary and their transport flux to the sea and ecological risks. However, the multi-media distribution characteristics and rules, migration and transformation processes of emerging organic pollutants in the estuarine environments are not clear enough.
Recently, some countries, including China, have brought emerging organic pollutants into the regulatory scope, which will bring important opportunities for the control of emerging organic pollutants. Researching the occurrence, migration and degradation of emerging organic pollutants in the estuarine environment will provide important support for estuary and marine environment protection.
The focus of this Research Topic is on studies that the occurrence, migration and degradation of emerging organic pollutants in the estuarine environment. It calls for original and novel papers including but not limited to the following research topics:
• The occurrence, distribution and risk of emerging organic pollutants in estuarine water environment and estuarine wetland.
• The multi-media distribution characteristics and rules of emerging organic pollutants in estuarine water, suspended particulate matter and sediment.
• The multi-media redistribution of emerging organic pollutants during sediment resuspension in estuaries.
• The variations of speciation of emerging organic pollutants in estuarine wetland sediments under alternate dry and wet conditions.
• The natural degradation process of emerging organic pollutants in the estuarine environment includes hydrolysis, photolysis and microbial degradation.
