Thus, high spatiotemporal resolution monitoring in a large scale is essential to better cope with their risks. Mass spectrometry (MS) techniques are sensitive and precise, yet complex, expensive, and time-consuming for antibiotic detection. 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. Yet, the applicability of ELISA can be further improved, such as developing a standardized quantification procedure for ELISA and microfluid chip-based ELISA kits and instruments.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 3","pages":"Article 100511"},"PeriodicalIF":5.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891603","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}

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. Water and MP samples were collected simultaneously from eight sampling locations. MP abundance in the Progo River ranged from 75.02 to 435.53 particles/m³. 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>). NPI scores (2.10–16.02) revealed slight to heavy polluted levels in the Progo River and were positively correlated with MP abundance (<em>r=0.336, p=0.461</em>). Multiple Linear Regression analysis (<em>R</em>^<em>2</em> = <em>0.639</em>) identified flow velocity, BOD, COD, turbidity, total coliform, and population number as significant predictors of MP distribution.

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.

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.

Among the various components of landfill waste, pharmaceuticals and personal care products (PPCPs), including both antibiotics and non-antibiotic compounds, pose significant environmental challenges. 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. By emphasizing the importance of understanding the combined effects of antibiotics and non-antibiotic pollutants in landfill environments, this review highlights the necessity of long-term ecological risk assessments for antibiotic-induced resistance as an emerging contaminant.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 3","pages":"Article 100508"},"PeriodicalIF":5.3,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838363","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}

A total of 180 fish were divided into three groups: Control (C), low-dose (LCA), and high-dose (HCA), with two replicates per group. Fish were observed daily for behavior, and water quality was controlled throughout the study. After 28-days of exposure, blood samples were collected to analyze plasma biochemical parameters. Sperm motility, concentration, and histological analyses of testes and liver tissues were also conducted. Results showed a significant dose-dependent decrease in cholesterol, triglycerides, and testosterone levels in the CA-treated groups, with the highest reduction observed in the HCA group (P &lt; 0.05). Sperm motility was significantly reduced in the low-dose (66.1 ± 2.2 %) and high-dose (36.5 ± 3.9 %) groups compared to the control group (79.5 ± 2.2 %). Similarly, sperm concentration and motility time were significantly reduced in the CA-treated groups (P &lt; 0.05). The gonadosomatic index (GSI) also decreased significantly in the treated groups, with the HCA group showing the lowest GSI (P &lt; 0.05), indicating impaired gonadal development. Histological analysis of the testes revealed delayed spermatogenesis, with the HCA group predominantly showing immature gonadal stages (Stage II), and a significant reduction in spermatocytes and spermatozoa. Liver histology indicated necrosis, cell death, blood congestion, and vacuolization in both the LCA and HCA groups, particularly at the high dose (P &lt; 0.05), suggesting hepatotoxicity. In conclusion, CA exerted significant endocrine-disrupting effects in fish, impairing sperm motility, gonadal development, and liver function in a dose-dependent manner. The high-dose treatment caused pronounced effects, including hepatocellular injury and a severe decline in reproductive health.

Indoor dust is well-documented as important vector for human exposure to emerging contaminants via inadvertent ingestion. Consequently, the main aim of the present study is to assess human exposure to MPs in settled indoor dust by determining concentrations, and characteristics (size, shape, and polymer type) of MPs in dust samples collected from houses (n = 30) and workplaces (n = 30) in Birmingham, UK. 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. Polypropylene (PP) and Polyethylene Terephthalate (PET) were the most abundant polymer types in the studied samples, followed by Polyvinyl Chloride (PVC). 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. The higher ingestion exposure to MPs in toddlers raises concern over potential adverse health effects due to their incompletely developed immune and nervous systems.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 3","pages":"Article 100506"},"PeriodicalIF":5.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806857","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}
