Environmental behavior and remediation technology of organophosphate esters:A review
Organophosphate esters(OPEs)have been extensively utilized in industries as flame retardants and plasticizers.However,the application of OPEs as additive-type flame retardants makes them prone to being easily released into environments,leading to pollution.OPEs,considered as emerging organic pollutants,have been detected in various environmental media worldwide.This paper provides a comprehensive summary of the recent research findings on the environmental distribution,hazards,transportation,transformation,and remediation technology of OPEs based on an extensive search and analysis of published literatures from the past five years.The findings indicate the pervasive presence of OPEs in various environment,such as soil,water,sediment and air.OPEs not only pose risks to human health through environmental exposure and food sources but also exert detrimental effects on water environment and soil ecology.OPEs exhibit diverse migration pathways within the environment,demonstrating their capacity to disperse over long distances.Hydrolysis is the dominant transformation process for OPEs in natural environments,while Fenton oxidation and photo degradation have been identified as effective remediation technologies for addressing OPEs contamination.
