| 1 | Concentrations of organophosphate esters in drinking water from the United Kingdom:Implications for human exposure显示文摘Data on the presence of organophosphate esters(OPEs)in drinking water and its significance as a pathway of exposure are limited.In this study,we measure for the first time,concentrations of eight OPEs in 50 UK drinking water samples.Arithmetic mean concentrations of ∑8OPEs were:6.4 and 11 ng/L in bottled(n=25)and tap water samples(n=25),respectively.Concentrations of ∑8OPEs in tap water(mean:11 ng/L)exceed significantly those in bottled water(mean:6.4 ng/L)(p˂0.01).Moreover,UK tap water is more contaminated with chlorinated,aryl-,and alkyl-OPEs than bottled water.The predominant OPEs detected were:tris(butoxyethyl)phosphate(TBOEP),tris(2-chloroethyl)phosphate(TCEP),and tris(2-chloroisopropyl)phosphate(TCIPP)with arithmetic mean concentrations in the two water sample types ranging between(3.5e3.8 ng/L),(0.60-3.0 ng/L),and(1.02-2.9 ng/L),respectively.Estimated daily intakes(EDIs)(mean and high-end exposure)via drinking water for different sectors of the UK population were:infants(0.93 and 6.4 ng/kg bw/day)˃toddlers(0.46 and 3.1 ng/kg bw/day)˃children(0.35 and 2.3 ng/kg bw/day)˃adults(0.28 and 2.1 ng/kg bw/day).Based on these data,exposure to ∑8OPEs via drinking water is much lower than via:food,indoor dust ingestion,inhalation,and dermal uptake for adults and toddlers.Reassuringly,our EDIs were lower than relevant reference dose(RfD)values.However,combining our drinking water ingestion data with exposure via other pathways revealed overall exposure to 2-ethylhexyl diphenyl phosphate(EHDPP)and TCIPP to approach health-based limit values for UK toddlers under a high-end exposure scenario. | Muideen Remilekun Gbadamosi Layla Salih Al-Omran Mohamed Abou-Elwafa Abdallah Stuart Harrad | 2023 | Emerging Contaminants2023，9，1： | 1 |
| 2 | Organophosphate esters in indoor and outdoor dust from Iraq:Implications for human exposure显示文摘Concentrations of 6 organophosphate esters(OPEs)were determined in 60 indoor(ID)and outdoor(OD)dust samples collected from 20 homes from Basrah,Iraq.From each home,two ID samples were collected,one from elevated surfaces(ESD)and one from the floor(FD)of the living room;while the OD samples were collected from the front yard of the same house.Total S6OPEs concentrations in dust samples ranged between 681 and 17900 ng/g with median concentrations of 5950,3590 and 1550 ng/g in ESD,FD and OD samples,respectively.Chlorinated OPEs were the most abundant compounds,contributing mean percentages of 88%,85%and 78%toΣ_(6)OPEs in ESD,FD and OD,respectively,with tris(1-chloro-2-propyl)phosphate(TCIPP)dominant.Concentrations of our target OPEs in ESD significantly exceeded those in FD(p<0.05)for tris(2-chloroethyl)phosphate(TCEP)and tris(1,3-dichloro-2-propyl)phosphate(TDCIPP).Ratios of median concentrations of OPEs in ID:OD ranged from 1.5 for tri-n-butyl phosphate(TNBP)to 8.0 for TCEP,indicating the significance of indoor sources.Concentrations of chlorinated OPEs in ID were moderately correlated(R=0.522-0.591,P<0.05)with those in OD samples,suggesting interchange of OPEs between the two environments.Concentrations of OPEs in OD from houses with a contiguous front yard car porch exceeded those in OD from houses without a car porch and were significantly higher(P<0.05)for TCEP,TCIPP and 2-ethylhexyl diphenyl phosphate(EHDPP).Emissions from parked cars and the associated home are likely sources of OPEs in the OD area.Based on the concentrations reported here,the estimated daily intake(EDI)for the Iraqi population through house dust ingestion are all well below the relevant reference dose(RfD)values. | Layla Salih Al-Omran Muideen Remilekun Gbadamosi William A.Stubbings Daniel S.Drage Mohamed Abou-Elwafa Abdallah Stuart Harrad | 2021 | Emerging Contaminants2021，7，1： | 0 |
