Contaminant occurrence, distribution and ecological risk assessment of phthalate esters in the Persian Gulf

PLoS ONE, Journal Year: 2023, Volume and Issue: 18(7), P. e0287504 - e0287504

Published: July 7, 2023

Due to the increasing population of world, presence harmful compounds, especially phthalate esters (PAEs), are one important problems environmental pollution. These compounds known as carcinogenic and Endocrine-disrupting chemicals (EDCs) for humans. In this study, occurrence PAEs evaluation its ecological risks were carried out in Persian Gulf. Water samples collected from two industrial sites, a rural site an urban site. Samples analyzed using magnetic solid phase extraction (MSPE) gas chromatography-mass spectrometry (GC/MS) technique measure seven including Di(2-ethylhexyl) (DEHP), butyl benzyl (BBP), diethyl (DEP), dibutyl (DBP), Dimethyl (DMP), di-n-octyl (DNOP), Di-iso-butyl (DIBP). The BBP was not detected any samples. total concentration six (Σ6PAEs) ranged 7.23 23.7 μg/L, with mean 13.7μg/L. potential risk each target evaluated by quotient (RQ) method seawater samples, relative results declined sequence DEHP >DIBP > DBP DEP DMP examined water had high algae, crustaceans fish at all sites. While showed lower mentioned trophic levels. study will be helpful implementation effective control measures remedial strategies pollution

Air–Sea Exchange and Atmospheric Deposition of Phthalate Esters in the South China Sea

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(30), P. 11195 - 11205

Published: July 17, 2023

Phthalate esters (PAEs) have been investigated in paired air and seawater samples collected onboard the research vessel SONNE South China Sea summer of 2019. The concentrations ∑7PAEs ranged from 2.84 to 24.3 ng/m3 with a mean 9.67 ± 5.86 0.96 8.35 ng/L 3.05 seawater. Net air-to-seawater deposition dominated air–sea exchange fluxes DiBP, DnBP, DMP, DEP, while strong water-to-air volatilization was estimated for bis(2-ethylhexyl) phthalate (DEHP). net atmospheric depositions were 3740 t/y sum but DEHP volatilized an average 900 t/y. seasonally changing monsoon circulation, currents, cyclones occurring Pacific can significantly influence concentration PAEs, alter direction magnitude particle fluxes. Consequently, dynamic process may drive transport PAEs marginal seas estuaries toward remote marine environments, which play important role environmental cycling global ocean.

Environments, Journal Year: 2023, Volume and Issue: 10(6), P. 99 - 99

Published: June 10, 2023

This review is a survey of recent progress in studies concerning the impact phthalic acid esters aquatic organisms. After introducing classification, properties, sources, fate, and toxic effects related to phthalates, an overview techniques extraction analysis these substances provided. As result, general concepts environmental bioindicators, biomonitoring systems, other phthalate contamination environment are presented. Recent bioaccumulation data different phthalates summarised table organised according type organism, tissue, geographical area sampling. Bioindicator organisms that more representative highlighted discussed as along with variables may be relevant assessment pollution substances. The final part looks at perspectives suggests new directions research objectives achieved future.
