The results showed that the degree of humification was increased by 18.31% and the emission of CH₄ was reduced by 30.21% in the ZY-2 inoculation with 0.3 L min⁻¹ kg⁻¹ organic matter (OM) aeration intensity treatment. Meanwhile, the structure of humus in the inoculation treatments was more complicated due to more polyphenols were participated in the formation of humus. The degradation of cellulose, hemicellulose, and lignin was increased by 35.41%, 23.92%, and 14.67% in the inoculation with 0.3 L min⁻¹ kg⁻¹ organic matter aeration intensity treatment, respectively. Therefore, more amino acids (27%), reducing sugars (26%), and polyphenols (14%) were produced for participating in the formation of humus. The inoculation of ZY-2 with an appropriate aeration intensity reduced the abundance of <i>Tepidimicrobium and Caldicoprobacter</i> that contributed to the emission of CH₄ while enriched <i>Bacillus</i>, <i>Oceanobacillus and Thermobifica</i> for OM biodegradation and humification. Therefore, we concluded that the <i>Streptomyces rochei</i> ZY-2 inoculant combined with 0.3 L min⁻¹ kg⁻¹ OM aeration intensity was an effective strategy to improve the fermentation quality and reduce CH₄ emission during rice straw fermentation.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"7025 - 7036"},"PeriodicalIF":3.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612012","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}

Within this landscape, multiple criteria decision aiding (MCDA) emerges as a pivotal tool, intricately intertwined with policy and decision-making processes to navigate uncertainties. This paper rigorously investigates application of MCDA in environmental decision-making processes and policy-making, shedding light on challenges and limitations in its practical implementation. While acknowledging MCDA's potential to address complex issues, the study critically examines its real-world utility in environmental policy-making. Drawing insights from 80 review papers and 9 related papers, the research underscores MCDA's evolving adaptability in managing diverse objectives and assessment criteria. It emphasises MCDA's value for policy makers by facilitating the implementation of effective policies, offering clarity for future policy directions, and assessing trade-offs among multiple goals. Despite these merits, the study identifies key challenges, including method selection influenced by expertise. Inherent uncertainties, varying stakeholder participation levels, and the delicate balance between expert-driven and collaborative approaches also present significant hurdles. Addressing subjectivity in evaluations, providing clear options in complex scenarios, and applying MCDA to dynamic problems are also identified as challenges. Additional obstacles include formulating criteria, integrating uncertainty, managing long-term perspectives, and ensuring practical and enduring benefits in policy decision-making. The paper highlights the lack of methodological guidance for the application of MCDA in environmental policy-making, emphasises the shortcomings of stakeholder engagement, and acknowledges data limitations as additional barriers. Consequently, given the uncertainties surrounding environmental issues, the study underscores the need for adjustments to effectively employ MCDA in such complex situations.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6967 - 6982"},"PeriodicalIF":3.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612271","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}

Low-cost adsorbents such as biochar are increasingly being promoted for treating industrial wastewater. This study investigated the effects and associated mechanisms of magnetite (Fe₃O₄) activation on lead (Pb, II) removal from aqueous solutions by biochars pyrolyzed from sawdust, wheat straw, canola straw, and manure pellet at 300, 500, and 700 °C. Depending on feedstock type, increasing pyrolysis temperature enhanced Pb(II) adsorption in pristine biochars. However, Fe₃O₄ activation reduced Pb(II) adsorption by up to 86%, likely due to decreased ash content, pH, and exchangeable cations. Cation exchange and the relative proportion of Ca²⁺/Mg²⁺ to K⁺/Na⁺ dominated the adsorption process via co-precipitation and outer/inner-sphere complexation. This process, depending on the feedstock type, occurred on either heterogeneous or homogenous surfaces of the biochars, with the data fitting better to the Freundlich or Langmuir model. We conclude that feedstock type and pyrolysis temperature, rather than Fe₃O₄ activation, are more critical when designing biochars for Pb(II) removal from wastewater. Biochars with higher inorganic fractions and greater proportions of Ca²⁺/Mg²⁺ to K⁺/Na⁺ should be prioritized for Fe₃O₄ activation to optimize Pb(II) removal from aqueous solutions.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6999 - 7012"},"PeriodicalIF":3.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612341","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}

The photocatalytic activity of nFe-TiO₂ was evaluated through the degradation of acetaminophen (ACE) under UV and visible light. nFe-TiO₂ induces a significant red shift to extend the absorption wavelength range from UV to visible light, identified by spectra analysis of UV/vis diffuse reflectance spectroscopy. The results show that higher Fe doping amount lead to lower reaction rate constants and degradation efficiency for methylene blue and ACE with nFe-TiO₂ under UV light. However, under xenon lamp irradiation, which includes the visible light region, an increase in the reaction rate constant of nFe-TiO₂ is observed. In general, the ACE degradation efficiency of the catalysts tested is better under sunlight than under the xenon lamp, possibly due to the higher light intensity of sunlight. Tests at various pH levels show that pH 7.0 yields the best ACE degradation with nTiO₂. After three reuse tests, the nFe-TiO₂ still had a good ACE degradation efficiency (&gt; 95%). The optimal operation parameters obtained are 20 mg nFe-TiO₂ with a calcination temperature of 500 °C for TiO₂ and Fe contents of 0.2%, which shows the best ACE removal of 99.9% under sunlight within 4.5 h and 55.1% under visible light (580 nm) within 8 h.

Many mechanisms favor pesticide dissipation in the biobeds. Pesticide losses to the atmosphere from biobeds have not been studied. Dissipation of pesticides frequently used in the Yucatan Mexico crops (2,4-D, atrazine, carbofuran, diazinon, and glyphosate) at 41 days period was evaluated in soil and a composite boimixture (soil, sisal, corn stover, compost, and seaweed). The volatile, run-off, and remaining fraction of each biomixture component was evaluated at the microcosm level for 72 h. Pesticides were dissipated by over 98% in the biomixture at 41 days. The highest values for volatile, run-off, and remaining fraction after 72 h were observed for diazinon (~ 43% in soil), 2,4-D (~ 70% in corn stover), and glyphosate (~ 73% in soil), respectively. This behavior shows a relationship with substrate type, exposure time, and pesticide type; these factors were statistically significant (<i>P</i> &lt; 0.05) on the pesticide concentrations in the studied fractions. The pH and lignin content were the factors that affected pesticide behavior in the substrates. Substrates presenting high remaining and low volatile pesticide fractions are promising for improving biobed performance in agricultural effluent treatment.
