Elemental phosphorus (P) is key to all life forms on earth. Efficient P management and control in natural environments especially water bodies of paramount importance the balance stability ecosystem both local global scales. In past decades, there have been numerous efforts devoted analysis as well its efficient removal water. However, occurrence species diverse with different properties, some even yet be known, posing challenges current analytic methods technologies. this review, we make an attempt clarify advances corresponding strategies. We hope provide a new perspective for purpose, i.e., linking speciation strategies, offer complementary guidance researchers that are normally specialized either field. Moreover, envision future directions fields, address need development species-orientated strategies high efficiency selectivity based advanced

Environment International, Год журнала: 2022, Номер 168, С. 107443 - 107443

By use of an integrated target, suspect, and non-target screening strategy, we investigated occurrence spatial distribution organophosphate esters (OPEs) in four types water (drinking resource water, surface groundwater, seawater) collected from Jiangsu Province (China) 2021 (n = 111). Eighteen out 23 target OPEs were detectable at least once these analyzed samples, the total concentrations (Σ18OPEs) various samples exhibited a descending order following as: groundwater (67026 ng/L) > (35803 drinking (21055 seawater (17820 ng/L). The highest concentration detected may be ascribed to pollution surrounding factories. Among OPEs, triethyl phosphate (TEP), tris(chloroethyl) (TCEP), tris (1-chloro-2-propyl) (TCIPP) most abundant congeners with average 407 ng/L, 143 475 respectively. Besides 18 further identified 17 suspect (3 them fully by authentic standards) on basis in-house OPE database, 2 organophosphates (OPs) feature fragments. One OPs was as bis(2-chloroethyl) 2-chloroethylphosphonate (B2CE2CEPP) matching retention time MS/MS data standard, other one preliminarily 2,4,8,10-tetra-tert-butyl-6-methoxydibenzo[d,f][1,3,2]dioxaphosphepin-6-one (TTBMDBDOPPO). We also observed that B2CE2CEPP shared similar structure TCEP, suggesting they have toxicological characteristics commercial sources. ecological human health risk assessments indicated all posed low or negligible aquatic organisms (algae, crustacean, fish), except for trimethyl (TMP) water.

Nontarget Identification of Novel Organophosphorus Flame Retardants and Plasticizers in Rainfall Runoffs and Agricultural Soils around a Plastic Recycling Industrial Park

Environmental Science & Technology, Год журнала: 2023, Номер 57(34), С. 12794 - 12805

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.

Organophosphate esters (OPEs) in plastic food packaging: non-target recognition, and migration behavior assessment

Environment International, Год журнала: 2023, Номер 177, С. 108010 - 108010

Опубликована: Июнь 2, 2023

Organophosphate esters (OPEs) are widely used as plasticizers in plastic food packaging; however, the migration of OPEs from to is largely unstudied. We do not even know specific number that exist packaging. Herein, an integrated target, suspect, and nontarget strategy for screening was optimized using ultrahigh-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS). The analyze 106 samples packaging collected Nanjing city, China, 2020. HRMS allowed full or tentative identification 42 OPEs, which seven were reported first time. Further, oxidation products bis(2,4-di-tert-butylphenyl) pentaerythritol diphosphite (AO626) plastics identified, implying organophosphite antioxidants (OPAs) could be important indirect source plastics. examined with four simulated foods. Twenty-six out detected at least one simulants, particularly isooctane, diverse elevated concentrations. Overall, study supplements list humans ingest well provides essential information regarding food.

The contamination status of novel organophosphate esters (NOPEs) and their precursors organophosphite antioxidants (OPAs) hydroxylated/diester transformation products (OH-OPEs/di-OPEs) in soils across a large-scale area China were investigated. total concentrations the three test NOPEs soil 82.4–716 ng g–1, which considerably higher than those traditional OPEs (4.50–430 g–1), OPAs (n.d.–30.8 OH-OPEs (n.d.–0.49 di-OPEs (0.57–21.1 g–1). One NOPE compound, i.e., tris(2,4-di-tert-butylphenyl) phosphate (AO168 = O) contributed over 65% studied OPE-associated contaminants. A 30-day incubation experiment was performed to confirm influence AO168 O on bacterial communities. Specific genera belonging Proteobacteria, such as Lysobacter Ensifer, enriched O-contaminated soils. Moreover, ecological function methylotrophy observed be significantly enhanced (t-test, p < 0.01) treated with O, while nitrogen fixation inhibited 0.01).

Nontarget Identification of Novel Organophosphorus Flame Retardants and Plasticizers in Indoor Air and Dust from Multiple Microenvironments in China

Environmental Science & Technology, Год журнала: 2024, Номер 58(18), С. 7986 - 7997

Опубликована: Апрель 24, 2024

The indoor environment is a typical source for organophosphorus flame retardants and plasticizers (OPFRs), yet the characteristics of OPFRs in different microenvironments remain less clear. This study collected 109 air samples 34 paired dust from 4 within university Tianjin, China, including dormitory, office, library, information center. 29 target were analyzed, novel compounds (NOPs) identified by fragment-based nontarget analysis. Target exhibited highest concentrations 46.2–234 ng/m3 20.4–76.0 μg/g, respectively, center, where chlorinated dominant. Triphenyl phosphate (TPHP) was primary OPFR office air, while tris(2-chloroethyl) dominated dust. TPHP predominant library. Triethyl (TEP) ubiquitous tris(2-butoxyethyl) particularly high 9 25 NOPs first time, mainly center such as bis(chloropropyl) 2,3-dichloropropyl phosphate. Diphenyl phosphinic acid, two hydroxylated methylated metabolites tris(2,4-ditert-butylphenyl) phosphite (AO168), dimer newly reported environment. widely associated with OPFRs, their human exposure risk environmental behaviors warrant further study.
