The discovery of the significant lethal impacts tire additive transformation product N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6PPD-Q) on coho salmon has garnered global attention. However, bioaccumulation and trophic transfer additives their products (TATPs) within food webs remain obscure. This study first characterized levels compositions 15 TATPs in Pearl River Estuary, estimated potential 21 estuarine species, identified priority contaminants. Our observations indicated that were prevalent environment. Eight, six, seven, 10 quantified shrimp, sea cucumber, snail, fish samples, with total mean 45, 56, 64, 67 ng/g (wet weight), respectively. N,N′-Diphenyl-p-phenylenediamine (DPPD) N,N′-bis(2-methylphenyl)-1,4-benzenediamine (DTPD) exhibited high bioaccumulation. Significant biodilution was only for benzothiazole, while DPPD DTPD displayed biomagnification trends based Monte Carlo simulations. mechanisms trophodynamics could be explained by chemical hydrophobicity, molecular mass, metabolic rates. Based a multicriteria scoring technique, DPPD, DTPD, 6PPD-Q as work emphasizes importance biomonitoring, particularly specific hydrophobic additives.

Limited knowledge on the structure of emerging organophosphorus compounds (OPCs) hampers our comprehensive understanding their environmental occurrence and potential risks. Through suspect nontarget screening, combining data-dependent acquisition, data-independent parallel reaction monitoring modes, we identified 60 OPCs (17 traditional 43 compounds) in effluents 14 wastewater treatment plants (WWTPs) Beijing Qinghai, China. These comprise 26 organophosphate triesters, 17 diesters, 6 organophosphonates, 7 organothiophosphate esters, 4 other OPCs. Notably, were newly WWTP effluents, 16 discovered matrices. Specifically, cyclic phosphonate, (5-ethyl-2-methyl-1,3,2-dioxaphosphorinan-5-yl)methyl dimethyl phosphonate P-oxide (PMMMPn), consistently appeared all with semiquantitative concentrations ranging from 44.4 to 282 ng/L. Its analogue, di-PMMMPn, presented 93% samples.

Plastic recycling and reprocessing activities may release organophosphate ester (OPE) flame retardants plasticizers into the surrounding environment. However, relevant contamination profiles impacts remain not well studied. This study investigated occurrence of 28 OPEs their metabolites (mOPEs) in rainfall runoffs agricultural soils around one largest plastic industrial parks North China identified novel organophosphorus compounds (NOPs) using high-resolution mass spectrometry-based nontarget analysis. Twenty twenty-seven were detected runoff water soil samples, with total concentrations 86.0–2491 ng/L 2.53–199 ng/g dw, respectively. Thirteen NOPs identified, which eight reported environment for first time, including a chlorine-containing OPE, an heterocycle, phosphite, three OPE metabolites, two oligomers. Triphenylphosphine oxide diphenylphosphinic acid occurred ubiquitously soils, up to 390 40.2 The downwind areas park showed elevated levels NOPs. contribution hydroxylated mOPEs was higher than runoffs. These findings suggest that are significant sources biotransformation further increase ecological human exposure risk.
