Tris(2,4-di-tert-butylphenyl) phosphite (AO168) is a widely utilized organophosphite antioxidant in the field of plastics. Throughout production and usage processes, AO168 can undergo oxidation convert into tris(2,4-di-tert-butylphenyl) phosphate (AO168═O), which has been identified as one novel organophosphate esters (OPEs). AO168═O now extensively present environment, with concentrations generally exceeding those traditional OPEs such triphenyl tri(2-chloroisopropyl) phosphate. Consequently, emerged significant concern that receiving attention from scientific community. However, there exists some controversy regarding formation mechanisms potential risks AO168═O. This Review provides comprehensive overview for first time environmental occurrence, pathways, toxicities, linked to AO168═O, aiming assist researchers policymakers obtaining an unbiased description its impacts on both environment human health. Given numerous unresolved aspects surrounding along wide greater should be devoted this emerging contaminant.

Organophosphate esters (OPEs) are a class of anthropogenic chemicals that have long been used as plasticizers and flame retardants. Dietary intake is an important OPE exposure pathway for humans. Since OPEs usually industrial additives in food contact materials (FCMs), can enter foods through to FCMs. This paper focused on FCM-related risks foods, summarizing the presence FCMs analyzing migration from food, assessing dietary risk Overall, levels were at higher than those foods. Processed packaged contained nonprocessed/fresh The investigations revealed be more likely transferred under conditions temperature longer time. We hope this work will extend our current knowledge apportionment sources highlight existing research gaps.

Halogenated organophosphate esters (OPEs) are increasingly used as flame retardants to replace polybrominated diphenyl ethers (PBDEs), which have been phased out due their confirmed persistence, toxicity, and ability undergo long range atmospheric transport. Non-halogenated OPEs primarily plasticizers. While human exposure PBDEs in the Canadian Arctic is well documented, it not case for OPEs. To assess Inuit living Nunavik (northern Québec, Canada), we measured 16 metabolites of halogenated non-halogenated pooled urine samples from last population health survey conducted Nunavik, Qanuilirpitaa? 2017 Health Survey (Q2017). Urine (n = 1266) were into 30 pools by sex (female; male), age groups (16-19; 20-29; 30-39; 40-59; 60+ years old) regions (Hudson Bay; Hudson Strait; Ungava Bay). Q2017 geometric means 95 % confidence intervals compared with data Measures Cycle 6 (2018-2019) (CHMS). systematically detected generally found at higher concentrations than both CHMS. Furthermore, urinary levels BCIPP BDCIPP (halogenated) lower CHMS while DPhP, DpCP DoCP (non-halogenated) similar between Across Q2017, BCIPHIPP had highest (geometric mean: 1.40 μg/g creatinine). This metabolite was should be included future surveys. Overall, our results show that exposed or rest general suggesting main current may consumer goods containing imported south rather long-range transport Arctic.

Industrial activities are a major source of organophosphorus flame retardants (OPFRs) and plasticizers in aquatic environments. This study investigated the distribution 40 OPFRs river impacted by industrial manufacturing plants Eastern China target analysis. Nontarget analysis using high-resolution mass spectrometry was further employed to identify novel compounds (NOPs). Thirty-four were detected water samples, with total concentrations 62.9–1.06 × 103 ng/L (median: 455 ng/L).

Among 26 identified NOPs, 17 reported for first time environment, including 14 organophosphate esters (especially 4 heterocycles 3 oligomers), 2 organophosphites, an organophosphonate.
