Article Abstract
With the global increase in organophosphate ester (OPE) usage, contamination has extended beyond environmental media into the human body, raising significant biosafety concerns. In this study, we conducted a meta-analysis of 254,581 data points from 98 studies spanning multiple regions worldwide. This large-scale synthesis allowed us to minimize regional bias and generate a quantitative profile of human OPE contamination and related risks. Our findings revealed notably high levels of TPHP and TCIPP in human samples. Additionally, we identified a significant correlation between OPE hydrophobicity (logK) and their distribution between dynamic and cumulative biological matrices. Subgroup analyses further demonstrated a strong inverse relationship between national Environmental Performance Index (EPI) scores and population-level OPE contamination, underscoring the role of environmental governance in reducing chemical exposure and biosafety risks. Based on these findings, we estimated adults' daily internal exposure doses and evaluated the corresponding health risks. Although exposure to eleven OPEs remained below established safety thresholds, our results highlight the need for ongoing efforts to curb environmental OPE emissions and promote safer chemical alternatives.

Organophosphate triesters （tri-OPEs） are synthetic phosphate derivatives that are primarily used as flame retardants and plasticizers. Tri-OPEs have become significant aquatic contaminants owing to their large production volumes and wide range of applications. Organophosphate diesters （di-OPEs） are closely related to tri-OPEs.

Background: Organophosphate tri-esters (tri-OPEs), widely used flame retardants, include alkyl-, halogenated-, and aryl-substituted types with distinct physicochemical properties. They may readily enter the ambient environment through volatilization, mechanical abrasion, and dissolution mechanisms occurring throughout the product lifecycle. To date, a range of monitoring methodologies incorporating sample pretreatment techniques have been developed to characterize the environmental distribution of tri-OPEs.

Organophosphate esters (OPEs), commonly used as flame retardants and plasticizers, are ubiquitous environmental contaminants, with high concentrations found in indoor house dust. Previously, we have reported that individual OPEs have adverse effects on HepG2 liver cells. However, real-world exposure involves mixtures of OPEs.

Organophosphate esters (OPEs) have emerged as a global environmental and health concern due to their persistent, bioaccumulative, and toxic (PBT) properties. Recently, their precursors-organophosphite antioxidants (OPAs)-and transformation products, which may exhibit greater persistence and toxicity, have gained attention as critical contributors to OPE-related contamination. This critical review examines the transformation mechanisms of "OPAs → OPEs → OPE derivatives" across environments, sources and emission inventory methodologies, and the environmental occurrence, persistence, and toxicity of these chemicals.

As widely used flame retardants and plasticizers, organophosphate esters (OPEs) are emerging contaminants that pose significant risks to aquatic ecosystems and human health. However, quantitative assessments of OPE pollution at the national scale are lacking due to scarce monitoring data and the unclear relationships between OPE concentrations and their driving factors. This study provides the first national-scale assessment of OPEs in Chinese surface waters by compiling a dataset of 355 sampling sites from 2010 to 2024 and developing a random forest model to quantify their spatial distribution, driving factors, and ecological risks.
