The pooled samples were collected from four Chinese cities, Yantai (Shandong Province), Ganzi (Sichuan Province), Huaihua (Hunan Province), and Lingshui (Hainan Province). The concentrations of HPAHs and PAHs were in the range of 4.26–633 ng/g lipid and 249–1642 ng/g lipid from the different cities. Although the levels of HPAHs in blood samples varied among the populations of the four cities, 1,5-dichloroanthracene (1,5-Cl₂Ant) was the predominant contributor to HPAHs in the serum samples, accounting for over 85.7 % of its total concentration. Furthermore, 1,5-Cl₂Ant serum concentrations increased significantly with age. Notably, molecular docking results show that 1,5-Cl₂Ant not only acquires the ability to bind d-AhR PAS-B domain, but also binds at the similar sites as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and benzo[a]pyrene (BaP), suggesting that 1,5-Cl₂Ant, like TCDD and BaP, may cause a wide variety of toxicity via AhR-mediated signaling pathways. The bioaccumulation potential of 1,5-Cl₂Ant in the human body and its associated toxicity observed in this study need special attention.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 3","pages":"Article 100518"},"PeriodicalIF":5.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144166752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, high spatiotemporal resolution monitoring in a large scale is essential to better cope with their risks.

The enzyme-linked immunosorbent assay (ELISA) is among a mature receptor-based assays that offer a cost-effective alternative and are particularly notable for their high throughput analytical capabilities. However, its high throughput power on environmental monitoring is underutilized. ELISA is remarkably rapid (3800–37,000 tests per day), inexpensive ($1.8 per test, capital costs ranging from $35,000 to $270,000), and ready-to-use (97 commercial kits available) for detecting frequently reported antibiotics. Adopting solid phase extraction decreases their limits of detection to as low as 0.125 ng/L. Their quantification results are robust as they also generally agreed well with those of MS methods. A conservative way at present is to use ELISA for initial screening of large numbers of samples, with subsequent quantification of a small proportion of “positive” samples through MS methods.

Therefore, the objectives of this study were 1) to investigate spatial distribution and characteristics of microplastic (MP) pollution in the Progo River, and 2) to examine MP relation to the Nemerow Pollution Index (NPI) based water quality status, 15 physicochemical biological water quality parameters, flow velocity and anthropogenic factors, marking the first comprehensive effort in Indonesia.

The MP characteristics were predominantly large, transparent, film-shaped particles, and identified variably as LDPE, PET, PP, PS, PAA, cellophane. The Pearson Correlation Test results revealed positive correlations between MP abundance and nine water quality parameters (TSS, turbidity, salinity, BOD, COD, phosphate, nitrate, detergent, Cd) and flow velocity. The other six parameters (pH, temperature, TDS, DO, total coliforms, Pb) and two anthropogenic factors (population number and density) were negatively correlated with MP abundance. Notably, DO exhibited a strong and significant negative correlation with MP abundance (<em>r = -0.770, p = 0.043</em>).

The isotopic analyses evidenced mixing phenomena, with both contributions from local rainfall and irrigation network. Combining chemical and microbiological approaches, the anthropogenic impact was evaluated by analysing a selection of traditional and emerging pollutants, such as pesticides, antibiotics and hormones, and assessing the extent of enterobacterial contamination and potential antibiotic resistance genes. Most of the investigated contaminants were found in concentrations from 0.1 ng/L to 632 ng/L, with the exception of Glyphosate and AMPA up to 5 and 20 μg/L, respectively. Even at these low concentrations, contamination of water resources is a serious issue because long-term exposure to such pollutants may cause detrimental effects. The most frequently detected pesticide was the fungicide Tricyclazole, while glucocorticoid Dexamethasone was the most frequent steroid hormone. Noteworthy is the ubiquity of Trimethoprim and a recurrent presence of fluoroquinolones. The occurrence of antibiotics at most sites, although at very low levels, is of environmental and public health concern, as they exert a selective pressure on bacterial populations, allowing the development of antibiotic resistant microbes, as highlighted by microbiological investigations.

Landfill leachate is a highly complex medium, consisting of diverse contaminants such as non-antibiotic pharmaceuticals (average concentration ∼1.74 μg/L), antibiotics (average concentration ∼527 ng/L), heavy metals, dissolved organic matter, and micro/nano-plastics (concentration range 0.64–2.16 mg/L). This unique mixture can alter the native microbial community structure, profoundly impacting antibiotic resistance, potentially disrupting soil and groundwater ecosystems, and threatening ecological balance. Existing research has extensively investigated the composition, physicochemical properties, environmental behavior, and microbial community structure of landfill leachate, leading to significant advancements in the field. However, due to the complexity and large volume of landfill leachate, current risk assessment approaches predominantly rely on conventional pollutant indicators, and most treatment strategies are designed for general contaminants. There is a lack of systematic descriptions that integrate pollutants with their direct impacts on microbial communities. This review focuses on the current pollution status, spatiotemporal trends, interactions, and migration risks of antibiotics and non-antibiotic pollutants in landfill leachate. In particular, we explore the in situ emergence of antibiotic resistance in landfill leachate (rather than the horizontal transfer of antibiotic resistance genes) and examine the influence of various leachate components on antibiotic resistance.

The average MPs concentrations were 155 ± 222 MP/mg in homes, and 125 ± 209 MP/mg in workplaces. Statistical analysis revealed the mean concentration of MPs in the studied homes was significantly higher than that in workplaces, which was attributed mainly to carpeting. In terms of morphology, various shapes of MPs (e.g., fiber, fragment, foam, foil) were identified, with fibres and fragments constituting ∼90 % of the identified MPs in all studied samples. Within the MPs particle size range (10–150 μm) investigated in the current study, the particle size fraction (50–100 μm) was predominant (&gt;49 %) in all the studied samples, followed by particles &gt;100 μm, with fibres having the largest average size (67 μm) among the detected MPs shapes.

Typical daily exposures of UK adults and toddlers to MPs through inadvertent ingestion of indoor dust were estimated at 56 and 103 MPs/day. The higher exposure of toddlers was exacerbated by their lower body weight with an estimated typical exposure of 9.7 MP/kg Bw/day, compared to 0.8 MP/kg Bw/day for adults.
