Abstract

Organophosphate esters (OPEs) widely exist in the environment, raising increasing concerns about their potential health risks. This comprehensive review surveyed the occurrence of OPEs over the last decade in indoor microenvironments (i.e. residence, in-vehicle, office, and school/daycare center), outdoors, foodstuffs, drinking water, and human-related specimen (i.e. breast milk and urine) with a view to unraveling age-specific exposure to OPEs. Multiple exposure pathways including inhalation, dermal absorption, dust ingestion, and dietary ingestion were considered to prioritize their relative importance. The results showed that dietary ingestion was the main contributor, followed by dust ingestion, regardless of age. A healthy diet with less contaminated food can effectively reduce OPE intake. OPE concentrations in air and dust followed the sequence of in-vehicle and office > school/daycare center > residence > outdoors. Compared to other indoor settings, exposure in schools/daycare centers and offices contributed to a greater OPE intake in non-adults and adults, respectively. The estimated daily intake of OPEs followed the sequence of infants > toddlers > children > teenagers > adults > elderlies. Overall, OPEs posed low health risks to all age cohorts, but infants were vulnerable and subject to the highest risk, largely attributed to breast milk ingestion. This review highlights the need for more toxicity and bioaccessibility studies on OPE mixtures and metabolites to further refine the health risk assessment of OPEs. [ABSTRACT FROM AUTHOR]

Abstract

Emerging aryl organophosphate esters (aryl-OPEs) have been employed as substitutes for organohalogen flame retardants in recent years; however, their environmental occurrence and associated impacts in urban estuarine sediments have not been adequately investigated, impeding regulatory decision-making. Herein, field-based investigations and modeling based on surface sediment and sediment core analysis were employed to uncover the historical pollution and current environmental impacts of aryl-OPEs in the Pearl River Estuary, South China. Our results revealed a substantial increase in aryl-OPE emission, particularly emerging aryl-OPEs, through sediment transport to the estuary since the 2000s. The emerging aryl-OPEs comprised 83% of the total annual input in the past decade, with an average annual input of 155,000 g. Additionally, the emerging-to-traditional aryl-OPE concentration ratios increased with decreasing distance from the shore, peaking in the highly urbanized riverine outlets. These findings indicate that inventories of emerging aryl-OPEs are likely increasing in estuarine sediments and their emissions are surpassing those of traditional aryl-OPEs. Our risk-based priority screening approach indicates that some emerging aryl-OPEs, particularly bisphenol A bis(diphenyl phosphate), can pose a higher environmental risk than traditional aryl-OPEs in estuarine sediments. Overall, our study highlights the importance of recognizing the environmental impacts of emerging aryl-OPEs.
