“…However, species such as DiBP and BBP (logKoct/wat between 3 and 5) showed RQs > 1 for fish coming from all the considered sites. This is consistent with previous studies (Zhang et al, 2020) reporting a high risk of DiBP to sensitive fish, respectively, from the Jiulong River and the East China Sea. The incidence, spatial and seasonal trends, and environmental risk of 6 PAE congeners (DEP, DPrP, DBP, DiBP, BBP and DEHP) and 2 NPPs (DEHA and DEHT) were examined in seawater and fish from different sites along the coast of Mahdia governorate (Tunisia), during April 2018-May 2019.…”

The new knowledge on the bio-transformations to which the plastic material is subjected, raise concerns about their role as environmental contaminants. Microplastic have been reported to be responsible for the release and distribution of aquatic contaminants such organophosphorus esters, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and phthalate esters. The occurrence, spatiotemporal trends, and ecological risk of phthalic acid esters (PAEs) and non-phthalate plasticizers (NPPs) released from microplastic were investigated in water and fish (Sparus aurata) from five sites along the coast of Mahdia governorate (Tunisia), during April 2018-March 2019. In seawater the most abundant and frequently detected congeners were dibutyl phthalate (DBP, 0.017 mg L–1 and 0.055 mg L–1), diisobutyl phthalate (DiBP, 0.075 mg L–1 and 0.219 mg L–1), di(2-ethylhexyl)phthalate (DEHP, 0.071 mg L–1 and 4.594 mg L–1), and di(2-ethylhexyl) terephthalate (DEHT, 0.634 mg L–1 and 2.424 mg L–1). (ΣPAEs: 1.416 mg L–1 and 5.581 mg L–1; ΣNPPs: 9.191 mg L–1 and 26.296 mg L–1), confirming that such compounds bioconcentrate through the food chain. DBP (0.389 and 0.817 mg L–1), DiBP (0.101 and 0.921 mg L–1), DEHP (0.726 and 1.771 mg L–1) and DEHT (9.191 and 23.251 mg L–1) were predominant also in S. aurata affirming that such compounds bioconcentrate through the food chain. Overall, Tunisian samples i) were much more contaminated than counterparts previously investigated for the same pollutants from other world areas, and ii) revealed NPPs at higher levels than PAEs, confirming that such plasticizers are increasingly replacing conventional PAEs.

“…Additionally, BPS was also one of the major dominant analogue in the sediment samples from S23, contributing 32.0%. This pattern was similar to that in sludge samples from 30 cities in China, in which BPA, BPF, and BPS were the most dominant analogues [43] . With regard to bisphenol analogues, higher concentrations were found in site S6 [Supplementary Table 6], which is located outside the chemical park.…”

Triclosan (TCS), triclocarban (TCC), parabens, bisphenols (BPAs), tetrabromobisphenol A and its alternatives (TBBPAs), and phthalate esters (PAEs) are typical endocrine-disrupting chemicals (EDCs), which have received increasing attention due to their potential adverse effects on ecological and human health. Human exposure to these EDCs is widespread. However, data regarding the distribution and related health risks of multiple EDCs in chemical parks are relatively scarce. In this study, 28 EDCs were determined in surface soil, sediment, and sludge samples collected from the Yangkou Chemical Industrial Park (Jiangsu, China). With the exception of TBBPAs, the distributions of Σ(TCS + TCC), Σ6parabens, Σ8BPAs, and Σ9PAEs in environmental media were as follows: sludge > sediment ≥ soil. No obvious differences were found regarding the concentrations of Σ9PAEs within the soil samples. Higher levels of Σ(TCS + TCC) (186 μg kg-1 dw) and Σ3TBBPAs (154 μg kg-1 dw) were found in the soil near a chemical manufacturer and the main sewage outlet of a wastewater treatment plant, respectively. The non-carcinogenic risks of EDCs from soil were estimated, and the risk levels were found to be a few orders of magnitude lower than the reported reference dose (RfD) values. The hazard indexes for all the samples were smaller than one, suggesting that the chemical industrial park posed a low risk to the workers. Additionally, the mass inventories of Σ(TCS + TCC), Σ6parabens, Σ8BPAs, Σ3TBBPAs, and Σ9PAEs were estimated to be 507, 90.6, 133, 20.7, and 1090 kg, respectively. These findings help to establish baseline concentrations for EDCs in soil, sediment, and sludge in a chemical industrial park.

“…The concentration of PAEs in the sediments has no significant correlation with the particle size distribution (p > 0.05), but there is significant positive correlation with OM (r = 0.73-0.84, p < 0.01), indicating that the distribution of PAEs in sediments is mainly affected by OM content. The concentrations of each PAE showed a significant positive correlation (r = 0.87 −0.95, p < 0.01), indicating that they may have the same pollution source [27]. In addition, TN and TP were also significantly positively correlated with PAEs (r = 0.59-0.73, p < 0.05).…”

The Fengshan River system is one of the major rivers in Kaohsiung City, Taiwan. This study investigated the concentration of eight phthalate esters (PAEs) in sediments of the river and the impact of potential ecological risks during the dry and wet seasons. The potential risk assessment of sediment PAEs was evaluated by adopting the total risk quotient (TRQ) method. The total PAEs concentrations (∑PAEs) in the sediments of the Fengshan River system are between 490–40,190 ng/g dw, with an average of 8418 ± 11,812 ng/g dw. Diisononyl phthalate (38.1%), bis(2-ethylhexyl) phthalate (36.9%) and di-isodecyl phthalate (24.3%) accounted for more than 99.3% of ∑PAEs. The concentration of ∑PAEs in sediments at the river channel stations is higher during the wet season (616–15,281 ng/g dw) than that during the dry season (490–1535 ng/g dw). However, in the downstream and estuary stations, the wet season (3975–6768 ng/g dw) is lower than the dry season (20,216–40,190 ng/g dw). The PAEs in sediments of the Fengshan River may have low to moderate potential risks to aquatic organisms. The TQR of PAEs in sediments at the downstream and estuary (TQR = 0.13) is higher than that in the upstream (TQR = 0.04). In addition, during the wet season, rainfall transported a large amount of land-sourced PAEs to rivers, leading to increased PAEs concentration and potential ecological risks in the upper reaches of the river.
