We designed this study to investigate one of the emerging environmental pollutants, airborne microplastics (MPs), in the air samples collected from various locations (pre-processing hall, office building, windrow composting area, compost refinery plant, landfill sites, incineration plant, and background) of the largest municipal solid waste processing and disposal complex (MSWPDC) in Iran. We employed a qualitative and quantitative approach using a stereo microscope and micro Raman spectroscopy to analyze the airborne MPs feature. Airborne MPs concentration ranged from 1.7 to 24.7 N/m³ with an average (± standard deviation (of 6.54 ± 5.08 N/m³. The highest concentrations were found in the windrow composting area, with an average concentration of 12.4 ± 9.32 N/m³. Given morphologies, fibers exhibited the highest proportion, making up approximately 64 % of the total. All airborne MPs had a size range between 5 and 2984 μm, mainly in the range of 100–500 μm. Regarding composition and color, PET/Polyester and transparent were the dominant, accounting for 26 % and 32 % of the total, respectively. Our findings showed a high concentration of MPs in the air of the Aradkooh MSWPDC. The findings underscore the importance of implementing stronger measures to reduce MPs emissions, as AMSWPDC could be a potential source of MPs pollution in the surrounding areas.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 1","pages":"Article 100459"},"PeriodicalIF":5.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reviewed the sources, distribution, and factors influencing ARGs and ARB in surface waters, and the methods used to measure and assess the risks posed to human and ecological health. The prevalence of ARGs and ARB is largely attributed to environmental contamination from fecal matter. Therefore, the distribution of AR on both regional and seasonal scales is significantly impacted by agriculture, which is related to economic development. In risk assessments, the risk of ARGs is mainly evaluated based on their mobility, pathogen carriage, and regional distribution, while the risk assessment for ARB is primarily focused on the quantities and diversities of pathogen-associated resistant bacteria. Based on this information, we suggest seven priority research questions regarding antibiotic resistance management in water environments: control of AR dissemination, advanced monitoring technologies, integrative impacts evaluation of antibiotics on resistance mechanisms and microbial communities, quantitative microbial risk assessment for ARB and ARGs, implications of horizontal gene transfer in non-pathogenic bacteria, synergistic risks of multiple resistance elements, and identification of high-risk ARGs and ARB in aquatic ecosystems.

The endocrine-disrupting potentials of PCBs are also investigated, particularly effects on thyroid hormone receptors. Through analysis of five years of data, results indicated that dioxin-like PCBs and congener PCB209 concentrations maintained low and had no marked temporal trends, but that the indicator PCBs and particularly PCB52, PCB153, and PCB180 concentrations increased. Furthermore, to evaluate binding of PCBs to the thyroid hormone receptor TRβ1, molecular docking simulations are performed. It is found that the PCBs of PCB28, PCB52, and PCB153 can interfere with triiodothyronine binding to TRβ1, which are comparable to the effects of the polybrominated biphenyl BB-153, a known thyroid function disruptor. What's more, the PCB180 binds to TRβ1 more strongly than that of BB-153.

This study investigated the effects of ethiprole enantiomers against microorganisms in sediment, duckweed, and human cells. The results showed that S-ethiprole degraded preferentially in sediment, demonstrating enantioselective behavior. In sediment, catalase and superoxide dismutase activities were significantly inhibited, and the frond number of duckweed preferably decreased with exposure to S-ethiprole at high concentration treatments (33 : 25 = R-ethiprole: S-ethiprole). Additionally, the content of chlorophyll <em>b</em> decreased nearly 2 times in R-ethiprole (0.42 mg/g) treatment group in comparison to S-ethiprole (0.20 mg/g) treatment. Cytotoxicity test revealed that S-ethiprole was 2 and 3 times more toxic than rac- and R-ethiprole. The expressions of CAT, SOD and caspase-3 were up-regulated in human cells treated with ethiprole enantiomers, indicating oxidative stress as a key factor in toxicity. Overall, S-ethiprole exhibited greater adverse effects than rac- and R-enantiomers in human cells.

The results revealed that influent flow, nutrient and pollutant loads, except for pharmaceuticals, increased during the festival. Notably, the load of specific organic pollutants (dissolved organic carbon, estrogen, and PAEs) increased by ∼50 %, which is more than three times the increase in influent flow. Despite this, the treatment process achieved high retention rates between 87 % and 100 %. Nevertheless, the overall effectiveness of the treatment process, the estrogen level in discharged effluents into the sea exceeded the environmental quality standard limits 7–12 fold.

The increasing concentration of PFAS in landfill leachate has been an emerging concern for waste management. This article presents a critical review of the current state-art of the technologies and processes for PFAS removal from landfill leachate. The article primarily addresses two aspects: (a) identifying the primary sources contributing to PFAS leaching, which includes examining various waste streams such as municipal solid waste (food packaging products, household consumer goods, cosmetics, electronic components), construction and demolition debris, and industrial waste (bio-solids, incineration ash, and manufacturing waste); (b) evaluating different technological options for PFAS removal from leachate, such as adsorption techniques, membrane filtration, electrochemical oxidation, photocatalytic oxidation, and biological treatment. The findings showed that the PFAS concentrations across different MSW components varied significantly, ranging from as low as 0.1 ng/L to as high as 150,000 ng/L, depending on the PFAS type and source. Additionally, the article explores the factors influencing the performance of these treatment technologies based on the experimental results, development stage, reaction time, and removal efficiency. Adsorption (granular and magnetic activated carbon) and membrane filtration processes have demonstrated higher PFAS removal efficiency ranging from 70 % to 95 %.
