The occurrence and profiles of 14 triester organophosphate flame retardants (OPFRs) plasticizers were investigated in surface water, tap rainwater, seawater collected from New York State. In total, 150 samples rivers ( n = 35), lakes 39), water 58), precipitation/rainwater 15), 3) analyzed for esters (OPEs). An additional nine Hudson River periodically to delineate seasonal trends OPE levels. total concentrations OPEs found at part-per-trillion ranges, with average that ranged 0.01 ng/L tripropyl phosphate (TPP) river 689 tris(2-butoxyethyl)phosphate (TBOEP) lake water. Tris(1-chloro-2-propyl)phosphate (TCIPP) was the most abundant compound among all types river-, lake-, rainwater similar but >3 times higher than those Chlorinated alkyl OPFRs accounted a major proportion concentrations. TCIPP, TBOEP, triethyl (TEP) >90% analyzed. Wet deposition fluxes estimated, on basis measured Albany, York, values between 440 5250 ng/m2. Among several bodies analyzed, Onondaga Lake contained elevated OPEs. Estimated daily intake via ingestion drinking up 9.65 ng/kg body weight/day.

Organophosphate esters (OPEs), used as flame retardants and plasticizers, occur at relatively high concentrations in urban air surface waters. We tested the hypothesis that some OPEs could be considered persistent mobile organic compounds (PMOCs), using poly parameter linear free energy relationship-modified Multimedia Urban Model (ppLFER-MUM) Toronto, Canada, a case study. Modeled emissions of ∑6OPEs 3300 (190–190 000) kg yr–1 were 10–100 times higher than polychlorinated biphenyls (∑5PCBs) polybrominated diphenyl ethers (∑5PBDEs). results suggested measured ∑6OPE stream ∼2000 ng L–1 originate from to transferred water mostly via precipitation. Water transport removed 7–28% total inputs compared 0.1–10% for PCBs 2–10% PBDEs. Chlorinated efficiently transported due their persistence solubility. Loadings Lake Ontario wastewater treatment plants, streams, atmospheric deposition 70%, 18%, 13%, respectively, loadings 3100 (1200–45 yr–1. Our support three chlorinated OPEs, tris(2-chloroethyl)phosphate phosphate (TCEP), tris(chloroisopropyl)phosphate (TCiPP), tris(1,3-dichloroisopropyl)phosphate (TDCiPP), fit profile PMOCs mobility

Chemical monitoring data were collected in surface waters from 57 Great Lakes tributaries 2010 to 13 identify chemicals of potential biological relevance and sites at which these occur. Traditional water-quality benchmarks for aquatic life based on vivo toxicity available 34 67 evaluated chemicals. To expand evaluation effects, measured chemical concentrations compared chemical-specific activities determined high-throughput (ToxCast) vitro assays. Resulting exposure-activity ratios (EARs) used prioritize the greatest concern: 4‑nonylphenol, bisphenol A, metolachlor, atrazine, DEET, caffeine, tris(2‑butoxyethyl) phosphate, tributyl triphenyl benzo(a)pyrene, fluoranthene, benzophenone. Water-quality unavailable five chemicals, but remaining seven, EAR-based prioritization was consistent with that quotients calculated benchmarks. identified three additional PAHs (anthracene, phenanthrene, pyrene) not prioritized using EARs. Through this analysis, an EAR 10-3 as a reasonable threshold above might be concern. better understand apical hazards potentially associated captured ToxCast assays, bioactivity matched adverse outcome pathway (AOP) information. The 49 assays via analysis aligned 23 potentially-relevant AOPs present AOP-Wiki. Mixture effects monitored estimated by summation values multiple individual assay or AOP. Commonly predicted outcomes included impacts reproduction mitochondrial function. approach provided screening-level assessment evidence-based effects. aids future provides testable hypotheses help focus those efforts. This also expands fraction detected biologically-based benchmark are contextualize results.
