With the acceleration of global industrialization, urbanization, and other human activities, various anthropogenic chemicals are used and discharged into the environment. The issue of environmental contamination has become increasingly severe and complicated with thousands of contaminants being presented such as metals, pesticides, microplastics, nanomaterials, persistent organic pollutants, and other emerging compounds. Continuous exposure to environmental pollutants can lead to adverse biological effects, which damage the growth and reproduction of animals and plants. It also endangers human health throughout the food chain, leading to various chronic diseases such as obesity, cancer, reproductive abnormalities, and organ damage. To understand the direct and indirect effects of human activities on the total environment, it is necessary to explore the biogeochemical behavior and biological response of environmental contaminants and provide the theoretical basis for preventing and reducing environmental contaminations. It is conducive to the rational control of environmental contamination and solving environmental problems gradually if we can understand the migration and transformation of contaminants in environmental media through in-depth research.
Research on the environmental distribution, environmental behavior, and toxicity effects of environmental contaminants is a key focus of ongoing studies. It will be helpful to prevent the deterioration of environmental quality and adverse human health effects due to high levels of environmental contaminants. Therefore, it is vital to control and dispose of contaminants in the whole process and to adequately understand their biogeochemical behaviors and biological responses of them. This Research Topic mainly focuses on research about the occurrence, distributions, source resolution, migration, and transformation of typical traditional and emerging contaminants and their influencing factors. It aims to evaluate the potential risks of contaminants to the distinctive ecological environment, biota, and human health. On this basis, after exploring the interactions among various contaminants, bioavailability, ecotoxicology, and biodiversity, the establishment of a biogeochemical cycle model of environmental contaminants and risk assessment through biological response mechanism can promote the effective control of contaminants. This collection is committed to exploring the mechanisms of pollution processes and effects, related technologies, and methods, supporting the control of environmental pollution and their potential risk assessment.
We welcome the articles focused on all the aspects of biogeochemical behavior and biological response to environmental contaminants, including but not limited to the following topics:
• Occurrence, migration, transformation, and the fate of environmental contaminants in the total environment;
• The adverse effects of the coexisting contaminants in the environment at the environmentally relevant concentrations;
• Exposure, bioaccumulation, toxic effect, and risk assessment of environmental contaminants;
• The toxic mechanisms of environmental contaminants in the ecosystem as well as for human health;
• Strategies and technologies for controlling and remediating polluted ecosystems;
• Effects of microorganisms on the biogeochemical behavior of environmental contaminants.
