AI Article Synopsis
- Organophosphate esters (OPEs) are increasingly recognized as pollutants, frequently used as alternatives to traditional flame retardants in various industries.
- The study analyzed 104 mollusks from 15 coastal cities in South China, finding that Σ8OPEs ranged from 48.2 to 1937 ng/g, with TDCIPP, TCPP, and TCEP as the most prevalent compounds.
- Results indicated regional differences in OPE concentrations, particularly higher levels in Guangdong, and although OPEs showed potential for biomagnification in mollusks, the health risks for consumers appeared low.
Article Abstract
Organophosphate esters (OPEs) are emerging pollutants and used extensively in industrial production as alternative to the traditional flame retardants. This study investigated the contamination characteristics and health risks of OPEs in 104 mollusks from 15 cities along the coastal region of South China. Σ8OPEs ranged from 48.2 to 1937 ng/g dw, with a mean value of 295 ng/g dw. TDCIPP, TCPP, and TCEP were the dominant OPEs. Different spatial distributions were observed, with higher concentrations in Guangdong Province. A statistically positive but non-significant linear correlation was found between the trophic level of mollusk and OPEs concentration. The trophic magnification factors were >1, suggesting that OPEs have the potential to biomagnify in mollusks. OPEs in mollusks pose low non-carcinogenic and carcinogenic risks to consumers. This study provides an important basis for managing the safety risks associated with OPEs in mollusks.

PM has a detrimental impact on human health and has become a focus of widespread concern. The tempo-spatial distribution of emerging pollutants has been extensively studied, while there is a scarcity of understanding their vertical distribution in atmospheric environment. Here we investigated the vertical profiles of phthalate esters (PAEs), organophosphate esters (OPEs), neonicotinoids (NEOs), and per-and polyfluorinated substances (PFASs) in PM at ground level (4.

Neurotoxicity of organophosphate esters (OPEs) and organophosphorus pesticides (OPPs) has been documented in toxicological studies, though epidemiological evidence remains inconsistent. The developing fetal brain is susceptible to environmental exposures. Thus, we aim to investigate how prenatal exposure to OPEs and OPPs as mixture affects offspring neurodevelopment in preschool-aged children.

TCIPP (tris(1,3-dichloro-2-propyl) phosphate) and TCEP (tris(2-chloroethyl) phosphate) are organophosphate ester flame retardants found in various consumer products, posing significant health and environmental risks through inhalation, ingestion, and dermal exposure. Research reveals these compounds cause oxidative stress, inflammation, endocrine disruption, genotoxicity, neurotoxicity, and potentially hepatotoxicity, nephrotoxicity, cardiotoxicity, developmental, reproductive, and immunotoxicity. This review summarizes the current knowledge on the toxicological mechanisms of TCIPP and TCEP and presents the latest data on their toxicological effects obtained in vitro and in vivo, using omic systems, and on the basis of computational modelling.

In addition to traditional organophosphate esters (tOPEs), emerging organophosphate esters (eOPEs) have increasingly been detected in the environment, but their risks remain unclear. This study detected 12 tOPEs and 7 eOPEs in surface water, sediment, and suspended particulate matter (SPM) samples from important aquatic habitats and drinking water sources in Yibin (YB), Yichang (YC), Shanghai (SH), and Poyang Lake (PY) within the Yangtze River basin. The total concentration of OPEs (ΣOPEs) in surface water, sediment, and SPM from these four regions were 22.
