However, little research has investigated their utility in detecting exposures specifically related to personal care product (PCP) use. Here, we assessed exposure to methyl-, ethyl-, and propylparabens after applying a lotion containing a known amount of each chemical. A convenience sample of 20 adults wore a wristband and collected all urine excreted for three days over two consecutive weeks, keeping their PCP use consistent. During one of these periods, participants were provided with a lotion containing a known amount of parabens and asked to apply it daily (4.57 g applied over three days, with one pump of lotion each day). Urine and wristband samples were extracted and analyzed for parabens via LC-MS/MS. Parabens present in the lotion were detected in 100 % of wristbands across both study periods, while urinary detection of these paraben ranged from 87 to 100 % across periods. Parabens were measured at higher levels in urine and wristbands collected during the lotion application phase. For every 10 % increase in wristband paraben concentrations, the total paraben mass excreted in urine increased an average of 4 % for methylparaben (95 % CI = 3–5 %, <em>p</em> &lt; 0.0001), 4 % for ethylparaben (95 % CI = 3–5 %, p &lt; 0.0001), and 6 % for propylparaben (95 % CI = 4–7 %, p &lt; 0.0001). This study shows that wristband concentrations reflect differences in use of a PCP containing parabens. Differences in wristband concentrations between study periods were greater than differences in urinary biomarkers of exposure, possibly because wristbands represent total potential exposure from dermal and inhalation routes. As this investigation only required a difference of one pump of lotion applied daily, the sensitivity of wristbands to capture differences in PCP use is promising.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"975 ","pages":"Article 179163"},"PeriodicalIF":8.2,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Results revealed that root exudates significantly promoted QS74 growth, biofilm formation, and EPS production compared to QSRB5. Soil inoculation with QS74 and root exudates enhanced soil organic carbon, microbial biomass, labile carbon, and dehydrogenase activity and aggregate stability indices, primarily due to increased EPS production. During soil conditioning stage of PSF, QS74 outperformed QSRB5 and uninoculated control by enhancing nutrient availability, soil biology and aggregate stability, leading to enhanced crop growth, nutrient uptake, and soil health in subsequent crop. This study demonstrates that EPS produced by PGPR facilitates the effective utilization of root exudate carbon during colonization, enriches the soil carbon and nutrients reservoir, enhances nutrient availability and positively influences the subsequent crop growth through plant-soil feedback.

Distinguishing between natural and anthropogenic leakage is challenging but crucial for assessing human impacts on reservoir seal integrity and developing effective mitigation strategies. To address this issue, this study presents an innovative approach that combines traditional groundwater analyses with fluid inclusion investigation to evaluate hydrocarbon seepage in both present and past shallow fluids, providing insights into long-term sealing history. The Val d'Agri oil field in Southern Italy, an environmentally sensitive area where hydrocarbon leakage is suspected, serves as an ideal case study. Raman spectroscopy of fluid inclusions in Pleistocene-Holocene fault-related calcite veins reveals the entrapment of saturated hydrocarbons with minor aromatic components, similar to those in the current reservoir. This indicates that temporary seal breaches occurred naturally in the geological past (earlier than oil extraction), likely due to fault-valve action during strong earthquakes. Hydrogeochemical analyses of groundwater indicate that the San Giovanni spring, located near productive oil wells, exhibits negative δ<sup>34</sup>S(SO<sub>4</sub>) (−14.20 ‰) and δ<sup>13</sup>C<sub>deep</sub> (−11.8 ‰) values, along with a high CO<sub>2</sub> concentration (5.4 mmol/L). These results indicate methane oxidation in the San Giovanni spring, related to long-term mixing between hydrocarbons, likely released during strong seismic events, and meteoric fluids.

This study investigates the contribution of Antarctic fur seals (<em>Arctocephalus gazella</em>) to the biological recycling of 15 essential and 5 non-essential nutrients on and around the Kerguelen Islands during their four-month breeding season. Nutrient concentrations of 59 fur seal scats from two colonies were examined and used to determine faecal nutrient output from lactating females using a bioenergetic model. We evidenced individual variability in the multi-nutrient composition of fur seal scats, with different types of potential fertilisers. Colony differences in scat compositions resulted in multi-nutrient release levels that did not simply reflect colony abundances. This suggests that estimating predators' nutrient release based on averages (diets, prey or faecal nutrient contents) likely overlooks important fine-scale spatial variability in their contributions. Collectively, fur seals deposit up to 628 kg (95 % CI [548–710]) of phosphorus (limiting on land), 46.4 [39.8–53.2] kg of iron (limiting at sea), and 5.9 [5.2–6.8] g of lead (toxic to most organisms). At sea, fur seal defecation could trigger locally significant enrichment events. On land, fur seal faecal nutrient deposition is spatially concentrated in coastal colonies where phosphorus deposition is in the range of global crop fertiliser use. We argue that the role of marine predators in the local nutrient dynamics of the Kerguelen area should not be overlooked, and that fine-scale variability in the nutrient input by such marine predators is important to consider in any local nutrient dynamic study.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"975 ","pages":"Article 179195"},"PeriodicalIF":8.2,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Degradation in water had little measurable effect on physical properties of TRWP; a shift towards larger particle sizes was mainly due to the mechanical stress from stirring. The total quantified extractables (TQE) of 27 chemicals and transformation products determined from tire particles were reduced by 90 % from TRWP and CMTT in water and by 85 % in soil. Most of this decrease occurs within the first months. For both materials, however, the speed of loss of TQE in water and in soil decreased drastically over time. Its kinetics was approximated by two phases of 1st order kinetics, resulting in half-lives from 17 days for diphenylguanidine (DPG) in phase 1 to 520 days for 6-PPD-quinone (6-PPDQ) in phase 2 of TRWP biodegradation in water. For soil, half-lives tend to be clearly longer in phase 2 compared to water but remained &lt;1000 days for chemicals such as benzothiazole sulfonic acid (BTSA), <em>N</em>,<em>N</em>′-diphenyl-<em>p</em>-phenylendiamine (DPPD) and hydroxybenzothiazole (OH-BT). For N-(1,3-dimethylbutyl)-<em>N</em>′-phenyl-1,4-phenylenediamine (6-PPD) and 6-PPDQ they exceeded 2000 days from TRWP. Only 1–15 % of TQE lost from the tire materials remained detectable at the end of the experimental period in the supernatant of the suspension or in leachates of the soil. Mostly benzothiazoles were determined from solution. The biodegradation experiments show an effective reduction of a large part of the chemical burden of TRWP of polar and moderately polar compounds. Despite that, TRWP may serve as a long-term reservoir for some of the tire related chemicals or their transformation products in the environment.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"975 ","pages":"Article 179240"},"PeriodicalIF":8.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
