Conventional Fourier transform infrared (FTIR) libraries lack the accuracy to identify these plastics because degradation alters their spectra-thermal oxidation adds new peaks, and abrasion causes characteristic peaks to fade. This creates a knowledge gap, leading to MP misidentification and flawed risk assessments for plastic pollution. To address this, we developed a new, environmentally relevant spectral library that significantly improved identification, increasing match rates by 7.3% for thermally oxidized plastics and by 23.8% for mechanically abraded plastics. We did this by subjecting seven commercial polymers (polypropylene [PP], polystyrene, rayon, low-density polyethylene [LDPE], linear low-density polyethylene, high-density polyethylene, and polyethylene terephthalate) to controlled thermal oxidation (100-200°C for 1-24 h) and by exposing PP and LDPE preproduction pellets to 40 days of mechanical abrasion (33 rpm; 3.41 rad s - 1). We then collected attenuated total reflectance (ATR)-FTIR spectra from these altered plastics and incorporated them into two newly developed spectral libraries. We tested these new libraries on 62 environmental MP samples (thermally oxidized) and 15 lab-generated particles (abraded), confirming a significant improvement in identification accuracy. Our findings underscore the importance of incorporating spectra obtained from plastics exposed to environmentally weathering processes into FTIR libraries, which represent a scientific advancement and a practical tool for more accurate MP identification and monitoring in environmental research.</p>","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"42 12","pages":"505-510"},"PeriodicalIF":1.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12872227/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146124204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

To address the inefficiency of existing algae removal technologies in eliminating AOM, this study investigates the feasibility of a combined technique utilizing chitosan quaternary ammonium salt (HTCC) and activated carbon (AC) for simultaneous algae removal and AOM elimination. First, the release of AOM during algae removal by standalone HTCC was examined. Second, AC with optimal AOM removal efficiency was selected, followed by evaluating the performance of the HTCC–AC combined technique in algae removal and AOM elimination. The disinfection byproduct formation potential before and after treatment was analyzed. Mechanism insights were elucidated through characterization techniques including Zeta potential, scanning electron microscope, Brunauer–Emmett–Teller, and FT-IR. Results indicated that standalone HTCC treatment poses a risk of AOM release, with released AOM originating from both intracellular and extracellular algal components. Wood-based activated carbon exhibited the highest AOM adsorption capacity at 6.43 mg/g. The HTCC–AC combined technique achieved removal efficiencies of 97.32%, 96.11%, and 91.13% for algal density, turbidity, and dissolved organic carbon, respectively. Notably, trihalomethane formation decreased by 94.56% compared with the control group, resulting in a posttreatment THM ratio of 0.15, significantly below the 1.0 limit specified in drinking water standards. The mechanisms of algal removal through the combined technique involve adsorption bridging and charge neutralization, while the removal of AOM occurs via π–π conjugation and hydrogen bonding interactions.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"43 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2025-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332928","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}

Indoor dust (n=15) from homes (n=10) and outdoor soil samples (n=31, yielding a total of n=46 original samples) were analyzed by γ-spectrometry, and α- and β-rate counting. Sixteen aliquots (16) from the 46 samples were analyzed by α-spectrometry for varying combinations of isotopic uranium, and isotopic thorium, and by Scanning Electron Microscopy with Energy Dispersive X-ray analysis. Detection of uranium and thorium confirmed that radioactive particles were of power plant origin. The presence of fission-related radionuclides was also confirmed by α- and γ-spectrometry. The highest activities of cesium-137 and lead-210 were observed in public areas outside of radiation protection zones near the PNPP, but evidence of fission related radionuclides was found up to 12.1 km. Testing of soil and dust collected <1 km from the plant detected up to 20 times the background activity for cesium-137 and lead-210. Elevated thorium-234, and trace activities of cobalt-60 and uranium-235 were detected in surface soils sampled <1 km from the plant using γ-spectrometry, including uranium (>0.5%) and thorium (>5.0%) in microparticles.

The CE/LN aerogel exhibited good mechanical properties and abundant functional groups, making it an effective adsorbent for the adsorption and removal of the antibiotic trimethoprim (TMP) from water. This study systematically investigated the effects of solution pH, aerogel dose, contact time, initial TMP concentration, temperature, ionic strength, and various water sources on TMP adsorption. The CE/LN aerogel demonstrated a higher TMP adsorption capacity of TMP than the CE aerogel across the entire pH range of 2.0–10.0. The adsorption process was well described by the Langmuir isotherm model and pseudo-second-order kinetic model. The CE/LN 6% aerogel achieved the highest adsorption capacity, with a theoretically maximal TMP uptake of 0.402 mmol/g at pH 6.0. However, high concentration of NaCl significantly reduced TMP uptake on the CE/LN 6% aerogel due to the electrostatic shielding effect. After five cycles of adsorption, the CE/LN 6% aerogel maintained a high adsorption capacity, retaining 80% of its initial uptake. Combined with the adsorption performance, the Fourier transform infrared spectrometry and X-ray photoelectron spectroscopy analyses spectroscopy analysis before and after TMP adsorption, it can be concluded that the adsorption mechanism involved hydrogen bonding, electrostatic interactions, and π–π electron donor–acceptor interactions. Thus, the CE/LN aerogel, with its simple preparation method, good adsorption capacity, and reusability, shows great potential for widespread application in the removal of antibiotics from water.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"42 6","pages":"243-254"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147897947","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}

Soils may also become contaminated with <i>B. anthracis</i> when livestock or wildlife succumb to anthrax disease. This study was conducted to assess the <i>in situ</i> remediation of soil using steam vapor to inactivate a <i>B. anthracis</i> spore surrogate (<i>Bacillus atrophaeus</i>) inoculated into soil samples. Tests were conducted using small columns (~0.04 m³ of soil) filled with either loam, clay, or a sandy soil. Following steam treatment, the <i>B. atrophaeus</i> spores were recovered from the test and positive control soil samples via liquid extraction and this liquid was subsequently dilution plated to quantify viable spores in terms of colony-forming units. Decontamination efficacy was assessed as a function of soil type, soil depth, soil moisture, soil temperature, and steam exposure time. Results showed that spore inactivation improved with increasing steam exposure time and diminished with depth. The clay soil generally exhibited the highest soil temperatures and correspondingly showed the highest inactivation of spores. Adding moisture to the soil prior to the steam treatment increased heat transfer within the soil column, and sealing the columns to mitigate steam leakage increased spore inactivation. The results showed that a steam mass of 40-50 kg applied per square meter of soil surface was sufficient to inactivate bacterial spores to depths between 7 and 10 cm. With bacterial spores on the soil column surface, a contact time of 15 min with the steam vapor at 99°C was sufficient for complete inactivation. These findings provide a foundation for estimating costs and time requirements for applying steam to the soil surface, and further confirmatory testing at field-scale is suggested.</p>","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"42 ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11980802/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143998295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
