Occurrence and seasonal disparity of emerging endocrine disrupting chemicals in a drinking water supply system and associated health risk

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: June 3, 2022

Abstract Contamination of drinking water with endocrine-disrupting chemicals (EDCs) raises concerns over the security and long-term sustainability clean supplies as well human exposure via daily intake. In this study, seasonal disparity occurrence six phthalates bisphenol-A in supply system associated health-risk were examined. The detection frequencies ∑6PAEs ranged from 24 to 100% winter whereas; summer it is below limit up 100%. DEHP was most prevalent phthalate congener ranging 1.14 8351.85 µg/L (winter) 0.552 410.29 (summer) surpassing permissible limit. However, BPA concentrations found under results suggested that PAEs concentration displayed significant variations highest lowest summer. assessed, indicating a possible health risk humans hazard quotient (HQ) > 1 for only. findings necessitate an immediate scrutiny these EDCs are critical implementing effective technologies at WTP scale ensure quality safety ascertain environmental health.

Freshwater water quality criteria for phthalate esters and recommendations for the revision of the water quality standards

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 279, P. 116517 - 116517

Published: May 27, 2024

With increasing urbanization and rapid industrialization, more environmental problems have arisen. Phthalates (PAEs) are the foremost most widespread plasticizers readily emitted from these manufactured products into environment. PAEs act as endocrine-disrupting chemicals (EDCs) can serious impacts on aquatic organisms well human health. In this study, water quality criteria (WQC) of five (dimethyl phthalate (DMP), diethyl (DEP), dibutyl (DBP), butyl benzyl (BBP) di(2-ethylhexyl) (DEHP)) for freshwater were developed using a species sensitivity distribution (SSD) toxicity percentage ranking (TPR) approach. The results showed that long-term (LWQC) SSD method could be 13.7, 11.1, 2.8, 7.8, 0.53 μg/L, respectively. Criteria continuous concentrations (CCC) derived TPR determined to 28.4, 13.1, 1.3, 2.5, 1.6 commonly measured in China surface waters at between ng/L μg/L. DBP, DEHP, di-n-octyl (DnOP) frequently detected PAEs, with occurrence rates ranging 67% 100%. ecological risk assessment decreasing order national level, DMP, DEP, DnOP. study will great benefit other countries revising standards conservation species.

First Data on PAE Levels in Surface Water in Lakes of the Eastern Coast of Baikal

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(2), P. 1173 - 1173

Published: Jan. 9, 2023

The increasing consumption of phthalates (PAEs), along with their high toxicity and mobility, poses a threat to the environment. This study presents initial data on contents six priority PAEs in water lakes located eastern shore Lake Baikal-Arangatui, Bormashevoe, Dukhovoe, Kotokel, Shchuchye. mean total concentrations Arangatui Bormashevoe (low anthropogenic load) were comparable those Kotokel (medium load, 17.34 µg/L) but significantly higher (p < 0.05) than Dukhovoe Shchuchye (high 10.49 2.30 µg/L, respectively). DBP DEHP main all samples. content was quite high, at some sampling sites it exceeded MACs established by Russian, U.S. EPA, WHO regulations. assessment showed that there is no potential risk humans associated presence drinking water. However, levels DEHP, DBP, DnOP pose sensitive aquatic organisms, as shown calculated quotients (RQs). It assumed origin studied both biogenic.

ICE-SSD Model: Bridging the Ecological Risk Assessment Gap between Plasticizer and the Substitute

ACS ES&T Water, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 6, 2025

The eco-safety of plasticizer alternative di-isobutyl phthalate (DiBP) has received continued concerns owing to its large usage as a and high detection frequency in environments. concentrations dibutyl (DBP) DiBP the surface waters ranged from ng/L μg/L. However, accurate ecological risk assessment alternatives is limited by data on toxic effects potencies. interspecies correlation estimation (ICE) model combined with species sensitivity distribution (SSD) was used assess DBP DiBP. acute reproductive predicted no-effect (PNECs) were derived 0.05 mg/L 1.23 μg/L for 0.16 0.51 based ICE-SSD models. Our results showed that risks (risk quotient (RQ) < 0.1) mainland China waterbodies, except Hangzhou Bay, acceptable. quotients indicated Yangtze River (RQ = 1.55 0.48), Hun 1.74 6.03), Bay 7.33 13.49) had relatively levels PNECs Furthermore, joint probability curves needed further concern. Thus, could effectively compensate lack toxicity assessment.
