Drought is one of the most severe environmental stresses affecting plant productivity. Plants in the Mediterranean climate zone are exposed to heat and drought in summer, and these conditions have a significant effect on plant growth and development. However, in this case, the entry of CO 2 into mesophyll cells is prevented and therefore the rate of photosynthesis decreases which ultimately causes a reduction in plant growth. In order to acclimate to stressful environmental conditions, plants exhibit several structural modifications to cope with these harmful conditions. This review highlights some aspects of anatomical adaptive changes in plants under drought stresssuch as a reduction in leaf size and angle, stomatal position, epidermal thickness and deposition of the cuticle to prevent the loss of water from the leaf surface. Furthermore, it elaborates the role of buliform cells in leaf rolling, structural adaptation in the mesophyll cells, and the presence of trichomes. Mesophyll cells and bulliform cells provide easier rolling of leaves in case of intense drought. In arid conditions, the economical use of water by plants is possible by closing the stomata and reducing transpiration.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"21 2","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139186235","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}

In acid treatment, the ceramsite surface generated a composite pore structure, thus the specific surface area of ceramsite is significantly increased through acid treatment. In alkaline treatment, hydroxyl functional groups were loaded on the surface of the ceramsite, therefore the adsorption capacity for heavy metals was significantly improved. The surface of modified ceramic particles carries a negative charge, which is beneficial for the adsorption of cations. Taking lead ions as an example, the adsorption performance of ceramic particles on heavy metals was tested, and the maximum adsorption capacity reached 33.2 mg/g. Furthermore, the modified ceramic particles exhibit good desorption and regeneration properties. The modified ceramsite offers advantages in terms of raw material sources and production costs compared to natural zeolite.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"17 12","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138604124","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 results showed the stress decreased with depth increased and they could be seen as two straight lines. The interval time in filling phase of unsaturated soil had little impact on the stress. The depth-settlement curves had big difference between the overall filling and layered filling that the settlement of layered filling was far greater than the overall filling.

However, the existing research focuses on the impact of digital economy on green total factor productivity, ignoring digital technology, which is a key technology for improving efficiency to achieve green development. Exploring the impact of digital technologies on green total factor productivity helps to understand the impact of digital economic development on green development from an internal perspective of the digital economy. This paper uses an SBM-GML index to measure regional green total factor productivity based on provincial level data and innovatively constructs digital technology indicators based on micro-level ICT patent data in China. Fixed-effects model is used to study the impact of digital technology on green total factor productivity and moderating model is used to examine the moderating effect of capital accumulation. The results indicate that: (1) At the national level, digital technology is conducive to the improvement of green total factor productivity, and the result passes the robustness test. From a dynamic long-term impact perspective, the effect of digital technology development on green total factor productivity is showing an increasing trend. (2) Digital technology’s effect on green total factor productivity is heterogenous. The results of the subregional heterogeneity analysis indicate that the effect is greater in the coastal regions and southern regions. The results of the heterogeneity analysis of the external environment indicate that the effect is greater in regions with smaller economies, regions with lower external economic dependence, and regions with lower government fiscal intervention. (3) Capital accumulation has moderating effect in the process of digital technology affecting green total factor productivity which will inhibit the improvement of digital technology development on green total factor productivity. Based on the conclusions, to better utilize the role of digital technology in promoting green development, it is necessary for the government to build a digital technology exchange platform, promote the balanced development of digital technology, and expand domestic demand to reduce the dependence on capital accumulation.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"17 2","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138601655","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 net confining pressures were controlled at 100 kPa, 200 kPa, 300 kPa and 400 kPa. The results showed that for the unsaturated moraine soil, c' and φ ' increase in the matric suction and their growth rates were similar. The relationship between volumetric strain and net confining pressure showed that the specimens were in a state of dilatancy with a small net confining pressure and the amount of dilatancy rapidly decreased and developed into a shear shrinkage state with an increase in net confining pressure. The last amount of shrinkage was stable at approximately 0.6%.

Previous studies have largely ignored the influence of reference points on food waste behavior and the role of human-to-human relational interactions, failing to capture their role in guiding residents’ food waste behavior (RFWBs). To address this gap, this study proposes a model that examines the role of reference dependence, normative internalization, and symbolic expectations in RFWBs, while introducing network embeddedness as a moderating variable. Using data collected from 981 respondents online, ordinary least squares were used to test the hypotheses. The results showed that reference dependence and normative internalization had a positive effect on reducing RFWBs with regression coefficients of 0.178 and 0.293 respectively, while symbolic expectations also had a positive effect on RFWBs with a regression coefficient of 0.227. Additionally, Network embeddedness played a significant moderating role in reference dependence, normative internalization, and symbolic expectations with RFWBs. This paper is theoretically innovative and the relevant findings fill the current research gap in the field of food waste, providing guidance and reference for government departments to formulate policies and promote residents to implement food waste reduction behaviors.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"26 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138604097","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}

Results showed: (1) soil pH and CEC improved with biochar rate; (2) urease activity was increased at the lower biochar rate (<2%) but reduced at the 5% rate, while acid phosphatase activity was not changed by biochar; (3) biochar addition reduced soil microbial diversity. The bacterial population like Proteobacteria, Gemmatimonadetes, Planctomycetes, Verrucomicrobia and Bacteroidetes enhanced by more biochar addition, while Actinobacteria and Chloroflexi were found less at the high biochar rate. Fungal strains like Ascomycota decreased by biochar addition, but Basidiomycota and Chytridiomycota increased at high biochar rates.
