Rethinking the pathway to sustainable fire retardants

Exploration, Journal Year: 2023, Volume and Issue: 3(4)

Published: July 6, 2023

Flame retardants are currently used in a wide range of industry sectors for saving lives and property by mitigating fire hazards. The growing safety requirements materials boost an escalating demand consumption retardants. This has significantly driven both the scientific community to pursue sustainable retardants, but what makes flame retardant? Here overview recent advances is offered, their renewable raw materials, green synthesis life cycle assessments highlighted. A discussion on key challenges that hinder innovation design principles creating truly yet cost-effective also presented. short work expected help drive development sustainable, expedite creation more safer society.

Discovering Novel Organophosphorus Compounds in Wastewater Treatment Plant Effluents through Suspect Screening and Nontarget Analysis

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(14), P. 6402 - 6414

Published: March 28, 2024

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. Compositional differences between two cities mainly attributed Hazard ecological risk assessment underscored substantial contribution chlorinated esters overall risks effluents. This study provides most OPC profiles date, highlighting need for further research occurrence, fate, risks, particularly

Non-target screening and risk assessment of organophosphate esters (OPEs) in drinking water resource water, surface water, groundwater, and seawater

Environment International, Journal Year: 2022, Volume and Issue: 168, P. 107443 - 107443

Published: July 30, 2022

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.
