Inferring atmospheric sources of gaseous organophosphate esters from spatial patterns

Environmental Toxicology and Chemistry, Journal Year: 2025, Volume and Issue: 44(3), P. 643 - 652

Abstract Organophosphate esters (OPEs) have emerged as pervasive environmental contaminants, with concentrations often exceeding those of traditional flame retardants and plasticizers by orders magnitude. Here, we present OPEs in the atmospheric gas phase collected using passive air samplers deployed coastal regions Quebec British Columbia southern Canada. Four OPEs, i.e., tri-n-butyl phosphate (TBP), tris(2-chloroethyl) (TCEP), tris(1-chloro-2-propyl) (TCPP), tris (phenyl) (TPhP) were reliably ubiquitously detected, TCPP showing highest level, followed TBP. Concentration levels TCEP are correlated each other population, possibly indicating emission from consumer products. Spatial patterns TBP TPhP more indicative industrial usage, airports being a major source for The positive relationships between population influenced ambient temperature, whereby size populated area around sampling site influencing concentration appears to be decreasing at higher temperatures.

Insights into organophosphate esters (OPEs) in aquatic ecosystems: Occurrence, environmental behavior, and ecological risk

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 54(8), P. 641 - 675

AbstractGiven the widespread use as flame retardants, plasticizers, and organophosphate esters (OPEs) received increasing scientific interests on their occurrence ecotoxicological research progress. This review comprehensively conducted bibliometric analysis surveyed OPEs in aquatic ecosystem (water, sediment, organisms) human-related (drinking water sewage) over past decade to unraveling knowledge gaps. The concentrations water, sediment were at range of not detected (n.d.) or several hundreds ng/g ng/L exhibited landuses-specific characteristics. electronic waste (e-waste) processing activities sewage discharge identified point sources environment. Emission source intensity, chemistry, content organic carbon important for partition transfer processes well hydrophobicity dominating absorption matter. Degradation, especially photodegradation reductive degradation, has application potential improving removal efficiencies chlorinated-OPEs (Cl-OPEs) being reluctant degrade. Generally, most have negligible ecological health risks, whereas those with moderate threats chronic effects should gain more attention. elucidates status pollution highlights need transport degradation studies traditional emerging metabolites further identify ecosystem.Keywords: Aquatic ecosystemorganophosphorus retardantsenvironmental behaviorpotential sourceecological riskregulationHandling Editors: Eakalak Khan Lena Q.
