A review on organophosphate Ester (OPE) flame retardants and plasticizers in foodstuffs: Levels, distribution, human dietary exposure, and future directions

Environment International, Journal Year: 2019, Volume and Issue: 127, P. 35 - 51

Published: March 19, 2019

Given the ongoing studies on adverse effects of organophosphate ester (OPE) flame retardants and plasticizers human health, there is an increasing scientific interest in risk exposure to OPEs via dietary intake. Using peer-reviewed literature published up 2018, this review surveyed compiled available reported data concentrations distributions 30 based their occurrence various food samples from around world. Regardless sampling locations or categories, 22 were detectable at least one analyzed sample, clear variations OPE levels among different categories. For instance, cereals fats/oils most contaminated by China Belgium, whereas desserts main polluted products Sweden. In contrast, vegetables, fruits, fluid dairy products, as primary categories Australia. Animal-based such eggs, fish meat contaminated, highest median found United State. The distribution patterns foodstuffs demonstrated a tremendous difference even when collected same country item. Rice had tris(2‑chloroethyl) phosphate (TCEP, mean: 29.8 ng/g dw) levels, 2‑ethylhexyl‑diphenyl (EHDPP, 4.17 ww), triphenyl (TPHP, 26.14 tris(2-chloroisopropyl) (TCIPP, 0.87 ww) tributyl (TNBP, median: 0.55 category Sweden, Australia, States, respectively. These discrepancies may be due variety reasons differences physico-chemical properties, extent usage, uptake, metabolic pathways, industrial manufacturing processes, level function habitat, accumulation degradability species. It worth noting that, its worldwide usage packaging materials, EHDPP was more prominently processed compared non-processed food. Based foods, conducted preliminary assessment through intake, which suggested that estimated daily intake (EDI) for humans 880 ng/kg bw/day (95th percentile). This value well below corresponding health reference dose given U.S. EPA (≥15,000 bw/day). Even so, not negligible some important factors dilution effects, cooking contribution yet unknown means exposure. Overall, highlights several gaps our understanding foodstuffs: 1) investigation contamination should extended other regions, especially North America European countries, where are widely used frequently detected environmental samples, 2) newly identified derivatives/by-products, e.g., OP diesters hydroxylated metabolites, have been end-products enzymatic metabolism degradation aqueous hydrolysis, co-exist with parent OPEs, could also screened precursor future studies.

A Review of a Class of Emerging Contaminants: The Classification, Distribution, Intensity of Consumption, Synthesis Routes, Environmental Effects and Expectation of Pollution Abatement to Organophosphate Flame Retardants (OPFRs)

International Journal of Molecular Sciences, Journal Year: 2019, Volume and Issue: 20(12), P. 2874 - 2874

Published: June 12, 2019

Organophosphate flame retardants (OPFRs) have been detected in various environmental matrices and identified as emerging contaminants (EC). Given the adverse influence of OPFRs, many researchers focused on absorption, bioaccumulation, metabolism, internal exposure processes OPFRs animals humans. This paper first reviews evolution types (FRs) pollution different absorption pathways by humans (such inhalation, ingestion, skin absorption), then summarizes impacts including their biological toxicity, persistence, migration, endocrine disruption carcinogenicity. Based limited available data results, this study also bioaccumulation biomagnification potential food nets. In addition, a new governance idea for replacement existing from source is proposed, seeking environmentally friendly alternatives to order provide ideas theoretical guidance removal OPFRs.

Establishment of a Target, Suspect, and Functional Group-Dependent Screening Strategy for Organophosphate Esters (OPEs): “Into the Unknown” of OPEs in the Sediment of Taihu Lake, China

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(9), P. 5836 - 5847

Published: April 23, 2021

Current environmental monitoring studies are generally confined to several target organophosphate esters (OPEs), and there is a lack of strategies for comprehensively screening all potential OPEs in samples. Here, an effective accurate strategy was developed the target, suspect, functional group-dependent by use ultrahigh-performance liquid chromatography-Q Exactive hybrid quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS), this applied analysis n = 74 sediment samples (including 23 surface 51 core samples) collected from Taihu Lake (eastern China) 2019. In these analyzed samples, we successfully identified 35 OPEs, them were reported region first time. addition, also presented other interesting findings, i.e., (1) OPE concentrations decreased with increasing distance coast lake; (2) newly 3-hydroxyphenyl diphenyl phosphate (meta-OH-TPHP) not statistically significantly correlated triphenyl (TPHP; r 0.02494, p 0.9101) but resorcinol bis(diphenyl phosphate) (RDP) (r 0.9271, < 0.0001) three OPEs; (3) summed aryl (∑arylOPEs) exhibited trends as depth decreased. Collectively, study provided that comprehensive sediments Lake, could have promising be extended matrices or

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(5), P. 1907 - 1918

Published: Jan. 25, 2023

Organophosphate esters (OPEs) discharged from wastewater treatment plants (WWTPs) have attracted increasing concerns because of their potential risks to aquatic ecosystems. The identification the structures OPEs is a prerequisite for subsequent assessment environmental impacts, which could hardly be accomplished using traditional target analytical methods. In this study, we describe use suspect and nontarget screening techniques organophosphate triesters diesters (tri-OPEs di-OPEs) in influent effluent samples acquired 25 municipal WWTPs across China. There are totally 33 different OPE molecules identified, 11 detected first time 4 new public. all tested samples, di-OPEs account significant portion (53% on average) total (ng/L−μg/L). More importantly, most not eliminated after these WWTPs, while some even accumulate. research priority based ecological risk was also analyzed, results reflected previously unrecognized exposure emerging living organisms. These findings present holistic understanding relevance country scale, will hopefully provide guidance upgrade protocols modification governmental regulations future.
