Polybrominated diphenyl ethers (PBDEs) and their substitutes, novel brominated flame retardants (NBFRs), are ubiquitously present in the aquatic environment of electronic waste (e-waste) dismantling region, leading to their inevitable absorption and accumulation by aquatic organisms, which can be transferred to human via directly aquatic product consumption or through food chain, thereby posing potential health risks. This study focused on fish samples from Guiyu and its surrounding areas, and found the total PBDEs concentrations were 24–7400 ng/g lw (mean: 1800 ng/g lw) and the total NBFRs concentrations were 14 to 2300 ng/g lw (mean: 310 ng/g lw). Significant positive correlations were found among PBDE congeners, among different NBFRs, and between NBFRs and commercial PBDEs that they replace. ΣPBDEs and ΣNBFRs in the intestine were 620–350,000 and 91–81,000 ng/g lw (mean: 83000 and 12,000 ng/g lw, respectively), significantly exceeding those in the gills, where ΣPBDEs and ΣNBFRs were 14–37,000 and 39–45,000 ng/g lw (mean: 9200 and 2400 ng/g lw, respectively). The ΣPBDEs and ΣNBFRs showed no non-carcinogenic risks to the target population through dietary intake. Despite the significantly higher daily intake of decabromodiphenyl ethane (DBDPE) compared to decabromodiphenyl ether (BDE209), the non-carcinogenic risk associated with BDE209 remained higher than that of DBDPE. Our findings can assist researchers in understanding the presence of BFRs in aquatic organisms, inhabiting e-waste dismantling areas, and in evaluating the associated health risks posed to humans through dietary exposure. © 2024 Elsevier B.V.

Unveiling the crucial role of iron oxide transformation in simultaneous immobilization of nanoplastics and organic matter

Science of the Total environment 2025年 959卷 178280页

Nanoplastics (NPs) have been found in natural environments. However, the sequestration of NPs and natural organic matter (NOM) coupled with the Fe(III) hydrolysis and subsequent iron oxides transformation remains unclear. Here, we investigated the behaviors of NPs during the dynamic transformation process of iron oxides in the presence of humic acids (HA). The quantification results of europium chelate-labeled polystyrene (PS) NPs and HA indicate that 87.60 % of NPs and 49.45 % of HA were sequestered in the precipitate by the end of the transformation (240 h). High-angle annular dark-field-scanning transmission electron microscopy-energy dispersive X-ray spectroscopy (HAADF-STEM-EDS) images show that NPs were doped into iron oxides during the recrystallization of ferrihydrite aggregates, while HA were adsorbed or penetrated into the nanoscale pores on the mineral surfaces, suggesting the formation of a stable iron oxides-NPs-NOM ternary nanocomplex with a core-shell structure. Fourier transform infrared spectrometer (FTIR) and two-dimensional correlation spectroscopy (2D-COS) analysis indicate that functional groups of iron oxides and HA, including hydroxyl, carboxyl, and Fe[sbnd]O bonds, played a role in the binding process. In the presence of HA, the stability of the coprecipitation system was enhanced due to the increased electrostatic repulsion, which facilitated the full incorporation of NPs with iron oxides. These findings provide a new insight into the simultaneous immobilization of NPs and NOM. © 2024 Elsevier B.V.

Science of the Total environment 2025年 958卷 177966页

作者： Han, Ziwei Jiang, Jiali Ni, Xuan Xia, Jing Yan, Chicheng Cui, Changzheng State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process School of Resources and Environmental Engineering East China University of Science and Technology Shanghai200237 China Shanghai Institute of Pollution Control and Ecological Security Shanghai200092 China

The widespread presence of microplastics (MPs) in drinking water systems and their risk of releasing additives have caused widespread concern. However, current research on the migration and risks of MPs and additives in the complete drinking water supply chain remains inadequate. In this study, micro-Raman spectrometer was used to track the entire transport process of MPs from the water source to the tap water, with concentrations ranging from 805 to 4960 items/L, and polyethylene and Polyethylene terephthalate were dominant. The removal efficiency of MPs at the drinking water treatment plant was 85.0 ± 5.2 %. However, chlorination increased the proportion of polystyrene by 40.1 ± 5.3 %. Chlorination increases the surface roughness and carbonyl index of polystyrene standards, and promotes the release of hexabromocyclododecane (HBCD) (482.0 ng/g–2208.7 ng/g). The non-carcinogenic risk index of HBCD ingestion through drinking water remains well below 1 for residents. Complete water treatment processes significantly reduce the risks posed by MPs, achieving reductions of 54.3 % in the pollution load index and 82.1 % in the potential ecological risk index. The estimated daily intake of MPs ingested by residents through tap water ranges from 33.4 to 45.6 items/kg/d. This study investigated the occurrence of MPs in the complete drinking water supply chain and the risk of chlorine disinfection for HBCD release, which could help develop more effective MPs control measures and risk management strategies. © 2024 Elsevier B.V.

Gehu Lake, as a key upstream reservoir of Taihu Lake, China, plays a crucial role in improving the water quality, and eutrophication control of the Taihu Lake Basin. Although the microbial communities are significantly important in maintaining the ecological health of lake, the microbial response to water quality, especially for eutrophication has been rarely reported in Gehu Lake. In this study, the water quality parameters and the corresponding effects on the structure and function of microbial communities were determined seasonally. It was found that the poorest water quality in summer (Water Quality Index = 116.52) with severe eutrophication (Trophic Level Index >70), was primarily driven by agricultural non-point sources (33.4%) and seasonal pollution (23.8%). The chemical oxygen demand (COD) was the most important indicator of water quality that affected the concentration of Chlorophyll-a (Chla) according to Pearson correlation analysis (p © 2024 Elsevier B.V.

Unveiling the impacts of biodegradable microplastics on cadmium toxicity, translocation, transformation, and metabolome in lettuce

Biodegradable microplastics (BMPs) may impact the environmental fate and ecotoxicity of Cd, but the effect mechanism in soil-plant system remain poorly understood. This study investigated the impact of BMPs (poly(lactic acid) (PLA) and poly(butylene adipate terephthalate) (PBAT) microplastics) on the Cd toxicity, translocation, transformation, and metabolome in lettuce (Lactuca sativa L.) by pot experiments. The results show that co-exposure to BMPs and Cd synergistically inhibited the shoot growth. 0.2 % PLA MPs enhanced but 2.5 % PLA MPs inhibited the photosynthesis;however, the dose of PBAT MPs was negatively correlated with the content of chlorophyll a. Moreover, the presence of 2.5 % PBAT MPs increased the nitrate content of leaves by 9.5 % compared to single Cd exposure. The partial least squares path model (PLS-PM) indicates that BMPs exacerbated the inhibitory effects of Cd on lettuce growth. PLA MPs enhanced K, Ca, Cu, and Zn accumulation in root stele, whereas PBAT MPs promoted Fe and Mn enrichment in epidermis. Furthermore, co-exposure resulted in higher inorganic and water-soluble Cd proportions in shoots. PLA MPs elevated Cd contents in cell wall fractions of both roots and shoots, while PBAT MPs increased Cd contents in shoot cell walls and root cells and soluble Cd ratio in shoots. BMPs enhanced Cd toxicity and bioaccumulation by downregulating the expression of ABC transporters and phenylpropanoid biosynthesis pathways, and the relative abundance of related metabolites. © 2024 Elsevier B.V.

In contrast to previous lab-scale studies, full-scale studies show that low temperatures do not significantly hinder pharmaceutical and personal care product (PPCP) removal in tertiary treatment constructed wetland (CW) systems. This study investigated PPCP removal pathways (substrate adsorption, plant uptake, microbial degradation) in two full-scale CWs, highlighting the differences between full-scale and lab-scale study outcomes. Results demonstrated that low temperatures did not adversely affect PPCP removal in full-scale CWs. Substrate adsorption was minimally impacted at a relevant concentration of 100 ng/L, unlike lab-scale studies with typically higher concentrations (1 mg/L). Plant uptake was not affected, as mature plants in CWs exhibited a lower PPCP uptake capacity compared to seedlings in lab-scale studies. Furthermore, low temperatures did not reduce microbial biodegradation performance. However, low temperatures increased dissolved oxygen concentrations in the influent, supporting aerobic microbial activity. These findings emphasize the value of full-scale CWs for stable PPCP removal under low-temperature conditions. © 2025

Trace copper ions are commonly found in different water bodies. They can effectively promote the degradation of various pollutants by peroxymonosulfate (PMS). However, the underlying mechanism of copper's action has not yet been clarified. Fluoroquinolone antibiotics (FQs), which are commonly used in humans and animals, often coexisting with copper metal in environmental waters, especially in aquaculture and medical wastewater. The presence of CuII under neutral conditions is found to significantly enhance the degradation efficiency of FQs by PMS. The coordination of CuII with FQs plays a crucial role in this process. Taking pefloxacin (PE), one typical FQs as an example, the structure of the copper complexes was determined using UV-visible spectroscopy, fluorescence spectroscopy, and DFT calculations as [Cu (PE) (H2O)4]2+. Comprehensive quenching experiments and electron paramagnetic resonance (EPR) test indicated that high-valence copper was responsible for the accelerated degradation. The combined results, including PMS decay and DFT calculations, indicated that CuII is initially reduced to CuI at a relatively slow rate and then rapidly oxidized to CuIII in the presence of PMS. The results highlight the valence transition of CuII/CuI/CuIII experienced during PMS activation, and the crucial role of contaminant-metal coordination in the valence transformation of copper. © 2024, The Authors.
