Here, owing to their porous crystalline lattice and tuneable molecular specificity, two-dimensional metal-organic frameworks (2D MOFs) present unique opportunities as an emerging class of transducers. Addressing the challenges of efficient nanomaterial design and device prototyping based on MOFs, this work demonstrates programmable liquid-phase epitaxy (LPE) growth of a Nickel(II) and 2-aminoterephthalic acid (BDC-NH2) based 2D MOF in modular microfluidic circuits on chip. Fully automated layer-by-layer (LbL) LPE yields homogeneous growth of crystalline 2D Ni-BDC-NH2 or Ni-MOF of thicknesses ranging from 2 to 25 nm on Si/SiO₂ substrate. Employing specially designed chips with metal microelectrode arrays (MEAs) as substrates, LbL-LPE approach is successfully used to carry out scalable integration of 2D Ni-MOF sensor arrays with high reproducibility. Using electrochemical impedance spectroscopy (EIS), the sensor chips are deployed for detection of diisobutyl phthalate (DiBP), one of the plasticizers linked to serious illnesses of the endocrine system, in concentration range from 1 to 20 µg/mL.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"14 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911462","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}

The study population consisted of 60 automobile technicians, including painters, smoothers, welders, and turners, all of whom had a minimum of two years of professional experience in their respective trade. Demographic data, along with information regarding health history and occupational and environmental exposure to lead, were collected via a structured questionnaire. Lead concentrations in the breathing air and blood samples were analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), in accordance with the National Institute for Occupational Safety and Health (NIOSH) method 7300. The results indicated that the average BPb level among all technician groups was 28.79 µg/dL, surpassing the threshold established by the American Conference of Governmental Industrial Hygienists (ACGIH). Conversely, the mean APb concentration was recorded at 0.038 mg/m<sup>3</sup>, which did not exceed the permissible limits. Statistical analysis revealed no significant correlation between APb and BPb levels, suggesting that exposure to lead may occur through alternative pathways beyond inhalation. Furthermore, BPb levels were positively correlated with years of work experience among participants. In light of the findings, it is strongly recommended that automobile repair technicians utilize personal protective equipment such as respiratory masks and gloves, adopt appropriate and hygienic work attire, ensure adequate ventilation, and maintain a clean and isolated environment for eating and drinking. Additionally, ongoing supervision and training programs should be implemented to mitigate lead exposure in this occupational cohort.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142890060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Since aeration is absent in anaerobic bioreactors, sludge mixing is usually done through mechanical mixing. Mechanical mixing speed is significant in terms of providing proper mixing and calculating the specific energy requirements of the plant. Moreover, the mixing speed affects the presence of different microbial species in the bioreactor. Therefore, this study investigates the effect of mechanical mixing speed in anaerobic sequencing batch reactors (AnSBRs) while treating synthetic domestic wastewater. The aim of the study is to find the optimum mixing speed, which gives the highest contaminant removal efficiency, stable sludge characteristics, higher gas production, and better microbial diversity in AnSBRs. Four AnSBRs were operated in parallel at different mixing speeds of 100 rpm, 200 rpm, 300 rpm, and 400 rpm at laboratory temperature (32 ± 2 °C) continuously for 30 days. Regular analysis of treated water quality and sludge characteristics and microbial profiling were performed. Colony morphology, biochemical tests, and 16 S rRNA based analysis were performed to isolate and identify the bacterial cultures. Mixing speed demonstrated a significant role and showed the highest contaminant removal at 400 rpm with 83% chemical oxygen demand, 74% biological oxygen demand, and 78% total suspended solids removals. The gases collected from the top of sealed reactors were identified as CH<sub>4</sub>, CO<sub>2</sub> and H<sub>2</sub>. Overall, from mixed liquor volatile suspended solids growth and gas production point of view, 400 rpm was the most suitable speed. Different bacterial species were isolated from the sludge in the form of circular, paired irregular, and filamentous colonies. The dominant species identified were Acinetobacter, Aeromonas sp, Citrobacter, Clostridium, Salmonella sp, Bacillus and Clostridium sp bacteria, confirming the maintenance of anaerobic conditions inside reactors.

Bacteria colonies and biofilms present in water distribution systems and aquatic systems respond to the presence of antibiotics by the generation of resistance genes and other determinants transmitted through the environment. In this perspective, we identify the opportunities and challenges of self-propelled micromotors in the fight against antimicrobial resistance by the elimination of antibiotics and bacteria in water. Recent progress is contextualized in the current scenario in terms of bacteria and antibiotics found in real settings and current removal technologies. As illustrated in this perspective, the unique features of micromotors result in a high surface area to-mass ratio for enhanced degradation capabilities, for both antibiotic removal and bacteria biofilms inactivation, as compared with static current technologies. The autonomous movement of micromotors allows to reach more volumes of water and even hard-to-access areas, offering great opportunities to reach hard-to-access pipelines, not accessible by current approaches. Yet, as envisioned in this perspective, micromotors are far away from real applications, hampered mainly by the main challenges of the treatment of high-water volumes. We also advocate scientists to include in the proof-of-concept studies real water and the evaluation of a major number of antibiotics and bacteria commonly found in real settings, as will be described in this perspective.

Among the seaweeds, three distinct seaweed species, viz., brown (Sargassum muticum (SM)), red (Gracilaria edulis (GE)) and (Kappaphycus alvarezii (KA)) were collected from the coastal area of Mandapam, Tamil Nadu and studied. The size reduction using a high energy ball mill at 500 rpm for 3 hours produced seaweed powders with sizes of 30-190 nm (KA), 70-120 nm (GE) and 40-220 nm (SM). Characterization was done using PSA, TEM, SEM, XRD and FTIR. The FTIR profile reveals major functional groups like alkenes, carboxylic acids, alcohols and amines. The seaweeds contained macro and micronutrients, especially potassium (2.67-13.4%). Biochemical profiling indicated high levels of amino acids, vitamins, fatty acids and growth hormones. Maize seeds were coated with 100 g of seaweed powder per kg of seeds using gum acacia (0.1%) as a sticky agent. Furthermore, the maize seedlings were sprayed three times (20, 30, 40 DAS) with seaweed powder @ 0, 25, 50 and 100 mg L-1. The combined application of seed coating and foliar spray of GE significantly increased the growth, physiological and biochemical parameters of the plants.
