Nanoparticles are included to enhance the evaporative and thermal properties. Conventional and modified double-slope solar still of similar features were produced using aluminium sheets and an experimental analysis was performed in sunny days. Solar-activated vacuum fan and external condenser are incorporated in conventional DSSS and termed as modified DSSS. Integrating condenser and solar-actuated vacuum fan in the DSSS significantly reduces the heat loss attained due to convection. Results signify that using ZnO, Al₂O₃ and CuO nanofluids with 0.1% volume concentration in the traditional DSSS enhances cumulative productivity by 10.34%, 13.79% and 17.24% respectively. In modified double-slope solar still, the cumulative productivity enhances by 13.30%, 20.69% and 25.62% using ZnO, Al₂O₃ and CuO nanofluids. Using a condenser and vacuum fan without nanofluid in the modified DSSS improves the collective distillate yield by 40% as related to a conventional SS without nanoparticles. Combined effect of condenser with vacuum fan and ZnO, Al₂O₃ and CuO nanofluid with 0.10% volume concentration in the modified DSSS increases the collective distillate yield by 58.62%, 68.96% and 75.86% respectively compared to a traditional SS without nanofluid. Results signify that the peak energy efficiency of the conventional and modified solar still using ZnO, Al₂O₃ and CuO nanofluid increases by 12.81%, 17.70% and 23.03%, and 23.27%, 23.24% and 28.37%, respectively. Results also indicate that the peak energy efficiency in modified solar still using ZnO, Al₂O₃ and CuO nanofluid increases by 47.13%, 47.42% and 52.92% as compared to traditional solar still without nanofluids. Results signify that the maximum exergy efficiency of the conventional solar still using ZnO, Al₂O₃ and CuO nanofluid increases by 32.82%, 38.22% and 55.21%, respectively.

To reduce harmful emissions and improve the fuel combustion characteristics, specialized additives are introduced into fuel oil. They lower the cost of heat production. Fuel additives offer several benefits, like improved operational characteristics of the boiler and lower fuel consumption. The conducted research revealed that the additive based on a particular combination of positively and negatively charged ions cuts down the ignition delay times of fuel droplets by 10-20% and anthropogenic emissions by 10-15%, and at the same time increase the reaction area of combustion by 20%. The findings indicate that specialized additives to fuel oil/water emulsions improve the characteristics of secondary atomization of droplets in the collisions with a solid surface, which leads to more efficient micro-explosive fragmentation.

This is especially concerning as the consumption of harvested marine species can pose potential health concerns. The arrival of the blue crab, Callinectes sapidus, to the Balearic Islands has led to the need to evaluate its environmental implications and potential as a food source as part of management efforts. In the present study, the concentrations of cadmium (Cd), lead (Pb), and mercury (Hg) in the muscle tissue of C. sapidus were evaluated at several locations in the Balearic Islands in the western Mediterranean Sea. A total of eighty-three blue crabs were examined (45 males and 38 females) and the concentrations of the heavy metals were evaluated. Regarding metal concentrations, overall, Hg was the most present followed by Cd and then Pb. Concentrations were also site dependent, with Es Grau having the highest Hg concentrations while in s'Albufereta the highest Cd concentrations were observed. Moreover, differences in metal accumulation were also observed between sexes, with juveniles and females exhibiting higher Cd concentrations than males. Furthermore, regarding potential human health concerns for consumption, the margin of exposure (MOE) for Pb were all above 1 and the estimated weekly ingestion (EWI) for Cd and Hg, were all below the established guidelines for food safety. These results highlight that the consumption of C. sapidus from the Balearic Islands does not currently pose a health risk the recreational fisheries sector. Considering these findings, the muscle tissue of C. sapidus is a valuable bioindicator for monitoring heavy metal levels, and continued site-specific monitoring is recommended for the coastal ecosystems of the Balearic Islands.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":"12579-12593"},"PeriodicalIF":5.8,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Simultaneous oxidation using mixed metal oxide catalysts is applied to remove these pollutants. Mn, Cu, Ce, MnCu, MnCe, and MnCuCe oxides supported on Al₂O₃ catalysts were prepared, and their catalytic activities were investigated. Among them, the MnCuCe/Al₂O₃ catalyst exhibited the highest conversions: 38% for NO at 250 °C, 95% for CO at 200 °C, and 35% for CH₄ at 500 °C. These superior catalytic performances were attributed to its amorphous structure, strong electronic interactions among metal ions, and an abundance of surface-active oxygen species. Catalytic activity tests showed that NO promoted the oxidation of CO and CH₄. Furthermore, temperature-programmed oxidation reactions indicated that NO, CO, and CH₄ oxidation are competitive reactions on the active sites. However, it was suggested that some of the NO₂ produced from NO oxidation acts as oxidants for CO and CH₄ to promote their oxidation.

Therefore, this study assessed air quality in two WWTPs in Toledo, Spain. One is located in an industrial area and processes both industrial and domestic sewage (WWTP1), and the other is situated in a rural area and treats domestic wastewater (WWTP2), handling approximately double the treatment flow. Moreover, the aeration systems in the bioreactors differ. Measurements were made over a period of 6 months and included levels of gaseous emissions, such as SO₂, CO, NOx, O₃, volatile organic compounds (VOCs), particulate matter (PM_2.5 and PM₁₀), and trace elements (TEs). Environmental and health risk indicators were calculated to estimate the impact of exposure to air pollution on nearby ecosystems and the population's health, respectively. The study revealed a low contribution of the WWTPs to the SO₂, CO, and PM levels. However, WWTP1 showed an NOx annual average concentration close to the legislated threshold, and the target O₃ value for the protection of human health was also exceeded. Regarding VOCs, the main contribution was the group of oxygenated aromatics.
