Industrial activities are a major source of organophosphorus flame retardants (OPFRs) and plasticizers in aquatic environments. This study investigated the distribution 40 OPFRs river impacted by industrial manufacturing plants Eastern China target analysis. Nontarget analysis using high-resolution mass spectrometry was further employed to identify novel compounds (NOPs). Thirty-four were detected water samples, with total concentrations 62.9–1.06 × 103 ng/L (median: 455 ng/L). Triphenylphosphine oxide diphenyl phosphoric acid ubiquitously up 620 127 ng/L, respectively. Among 26 identified NOPs, 17 reported for first time environment, including 14 organophosphate esters (especially 4 heterocycles 3 oligomers), 2 organophosphites, an organophosphonate. Bis(2,4-di-tert-butylphenyl) hydrogen phosphate 2,2-dimethylpropoxy(propyl)phosphinic high predicted persistence or toxicity widely detected, semiquantified 990 1.0 Structurally similar exhibited consistent variation trends, suggesting common emission source. Estimated annual discharges sea 20.6–37.0 kg/yr 30.8–161 NOPs. These findings indicate that contribute NOPs catchment its estuary, posing ecological risks both terrestrial marine

Greenhouses offer optimum growth conditions for plants and create a unique microenvironment workers who work in them. Information about human exposure to UVAs particularly those employed agricultural greenhouses remains unknown. In the present study, North China were comprehensively analyzed screened. The geometric mean concentration of ∑10UVAs greenhouse plastic films (132 ng/g) was found significantly higher than that control (27.1 (p < 0.001), with UV-531 (35.9 UV-326 (24.9 as dominant components used films, followed by soil fine particles, indicating elevated levels greenhouses.

ABSTRACT The demand for sustainable resources in production and improvement of various properties polymer materials is increasing. In this study, cellulose sulfate (CS) was synthesized from microcrystalline used as an additive at different ratios (5% 10%) the semirigid polyurethane foam (SrPUF). effects CS on mechanical properties, combustion behavior, thermal stability SrPUF were extensively investigated by rigorous tests such tensile strength, flexural UL 94 vertical burn test, thermogravimetric analysis (TGA). findings indicate that incorporating a 10% contributed to considerable advancement with increase 51.39%. Additionally, strength improved markedly, rising 47 kPa impressive 147 kPa. test showed flame spread rate containing experienced substantial decrease, while maximum degradation temperature ( T dmax ) increased 384°C 405°C. char yields 0%, 5%, added 5.61%, 6.84%, 13.01%, respectively. conclusion, study demonstrates doping SrPU significantly enhances its durability both aspects.
