Decabromodiphenyl ethane (DBDPE), a key alternative to deca-BDE (BDE-209), has been ubiquitous in the receiving ecosystem. However, little is known about its uptake process and fate plants. Here, plant absorption, distribution, metabolism of 14C-DBDPE under two distinct exposure pathways (i.e., soil-root airborne dust-leaf) were investigated with three vegetables (cherry radish, water spinach, eggplant). DBDPE was absorbed primarily accumulated directly exposed roots leaves, translocation factors other tissues 0.04-0.77 0.73-12.80 × 10-3, respectively. leaves more difficult transport as most did not enter interior but stored waxes (>90%). Furthermore, within found mostly through waxy layer penetration (>97%). The majority localized cell walls (52.6 75.6%, respectively) organelles (22.7 45.5%, tissues, substantially restricting in-plant translocation. Debrominated products detected roots, barely blocked by layer. Moreover, stable soils dust without degradation. Our findings contribute deeper understanding environmental soil-plant dust-plant systems.

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.
