Organophosphate flame retardants (OPFRs) are a class of substances that pose potential risks to human health and ecosystems due their large-scale production, wide range applications, ubiquitous presence in the environment. With for long-range atmospheric transport (LRAT), OPFR pollution high-altitude areas has become an increasing concern. Herein, general pretreatment method OPFRs across various sample matrices was established combined with gas chromatography-mass spectrometry (GC-MS), utilizing programmed temperature ramp vaporization chamber enable high-throughput detection environmental matrices. were quantified soil, grass, tree bark, wild rat liver samples collected from Qinghai, China (elevation: 2657-4635 m), occurrence bioaccumulation behaviors systematically investigated. All contaminated OPFRs, ∑OPFR concentrations showing trend (mean: 439 ng/g, median: 420 ng/g) > grass 338 273 soil 190 162 bark 125 116 ng/g). Paired Spearman correlation analysis showed ∑OPFRs significantly positively correlated (P = 0.0023), indicating is main source grass. Among samples, tris(2-chloroisopropyl) phosphate (TCIPP) tris(2-chloroethyl) (TCEP) had highest contribution rates ∑OPFRs, cumulative contributions 60.9 %, 48.6 76.5 71.1 respectively, proportion industrial sources reaching this area through LRAT relatively high. Biomagnification factor (BMF) revealed exhibited significant biomagnification effects within soil-grass-rat terrestrial food chain. The ecological risk assessment results indicated study high risk, aryl-OPFRs posing greatest risk. Our findings provide crucial foundation further investigation into contamination characteristics regions.

Studies on dietary exposure to organophosphate esters (OPEs) and diesters (di-OPEs) are limited, especially regarding di-OPEs their presence in raw grains, which fundamental staples of the human diet. In this study, 18 OPEs 8 were measured 289 grain samples from 13 major grain-producing regions China belonging four types: wheat, rice, maize, soybean. Tris(2-chloroisopropyl) phosphate (TCIPP) tris(2-ethylhexyl) (TEHP) dominant OPEs, while bis(2-ethylhexyl) (BEHP) was main di-OPE. The highest concentrations both ∑OPEs ∑di-OPEs observed soybean (median: 14.9 1.87 ng/g, respectively), followed by wheat (4.79 1.69 ng/g), maize (2.63 1.10 rice (2.37 0.726 ng/g). regional distribution relatively homogeneous. significantly higher Sichuan Shandong provinces, whereas spatial patterns differed, suggesting separate sources for di-OPEs. Soil type, straw turnover, pesticide use could affect TEHP, tri(2-chloroethyl) (TCEP), triethyl (TEP) respectively. Except TEHP tris(1,3-dichloro-2-propyl) (TDCPP), whose similar polished other accounted only 1.9-36 % those reported previously, indicating industrial processing as source these marketed grains. estimated daily intake through consumption 25.0-40.4 ng/kg bw/d 7.55-11.7 bw/d, respectively, primarily contributed than dust ingestion drinking water, that is exposure. Di-OPEs directly ingested grains derived metabolism parent implying estimating OPE based internal di-OPE levels inaccurate warrants further research.
