Environmental behavior and ecological impact of organo-metal complexes

Abstract

Heavy metals are common pollutants. The migration and toxicity of heavy metals are related to their forms. Organometal complex is one form of heavy metals. In recent years, there are more studies on heavy metals but less on Organo-metal complexes. Organo-metal complexes formed by the direct connection of metal atoms and carbon atoms. This paper illustrates the formation and influencing factors of Organo-metal complexes. Through literature study, it is found that the formation of organo-metal complexes is affected by pH, microbial and UV. Meanwhile, the formation of Organo-metal complexes will affect the migration and transformation of heavy metals. Organo-metal complexes are widely dispersed physically and chemically. The ecological risks of Organo-metal complexes are explained from the aspects of plants and humans. Organo-metal complexes can transport through the food chain from plants to animals and eventually accumulate in humans. The formation and transformation of Organo-metal complexes are important components of biogeochemical cycle. Studying the formation process and influencing factors of Organo-metal complexes not only provides a new method for metal poisoning, but also gives a new approach for the treatment of heavy metal pollution and the restoration of natural environment.
