As the hot issues of environment and geochemistry sciences, environmental geochemistry investigating both elements and pollutants in soil, water, air, and organism links their behavior and effects in pedosphere, hydrosphere, atmosphere, and biosphere systematically. Typically, biogeochemical cycles of some biogenic elements, such as carbon and nitrogen, are closely related to the global climate change through greenhouse gases, while some trace elements, usually known as toxic heavy metals in the environment, pose significant risks to both ecosystem and humans. Besides the traditional chemical pollutants, recently, the emerging contaminants, such as persistent organic pollutants (POPs), nanoparticles, microplastics, and antibiotics, have been attracting extensive concerns, due to their potentially environmental risks. Therefore, faced with these challenges, investigations of the environmental biogeochemistry of elements and emerging contaminants are of great significances for the environmental protection and human health. Both their environmental biogeochemistry and pollution control should be explored.

This special issue aims to provide contributions from a variety of topics relating to environmental biogeochemistry. Review articles which describe the current state of the art are encouraged. The original contributions describing and reporting recent advances and developments in the field of environmental biogeochemistry of biogenic elements, metals, and emerging pollutants are especially welcomed. Those papers and contributions treating similar or related topics, still of interest in the field of environmental pollution and public health research, are also welcomed in this special issue.

Potential topics include but are not limited to the following:

• Biogeochemical cycles and climate change
• Environmental biogeochemistry of trace metals and metalloids
• Environmental biogeochemistry of emerging contaminants
• Environmental biogeochemistry of persistent organic pollutants (POPs)
• Environmental biogeochemistry of nanoparticles
• Environmental biogeochemistry of microplastics
• Environmental biogeochemistry of antibiotics
• Soil pollution and remediation
• Water pollution and control
• Air pollution and human health
