On the other hand, organic farming offers a more environmentally friendly and low-intensity alternative. Amphibians, as sensitive indicators of environmental changes, are significantly affected by agricultural activities, making them vital for assessing ecosystem health. The objective of this study was to assess genotoxic and cytotoxic parameters in erythrocytes, and leukocyte profiles of <em>Leptodactylus luctator</em> and <em>Rhinella arenarum</em> populations inhabiting aquatic environments associated with different agricultural intensifications (conventional management and organic management). Water quality, and hematological biomarkers, like micronuclei (Mn), erythrocyte nuclear abnormalities (ENA), cytotoxic damage (CYT) and leukocyte profiles, were assessed in amphibian populations from agroecosystems with organic and conventional agricultural management practices. It was recorded that water bodies within organic agroecosystems exhibited lower Total Dissolved Solids and higher Dissolved Oxygen levels, indicating improved water quality. Populations of <em>R. arenarum</em> from conventional agroecosystems exhibited higher values of Mn, ENA, and CYT compared to those from organic agroecosystems, with the difference being statistically significant for the ENA parameter. In <em>L. luctator</em> populations, no significant differences were observed in the parameters related to geno/cytotoxic damage. Leukocyte profiles of both <em>R. arenarum</em> and <em>L. luctator</em> populations in organic agroecosystems showed lower percentages of lymphocytes and higher percentages of neutrophils and eosinophils compared to conventional agroecosystems, indicating healthier leukocyte profiles. The percentage of basophils and monocytes, as well as the N/L index, were higher in populations from organic agroecosystems, although statistical tests did not reveal a significant difference. The study demonstrates the potential benefits of organic farming in mitigating the negative effects of agricultural intensification on water quality and amphibian populations.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000267/pdfft?md5=518cdd4b78c41c66f4ad8436c146972a&pid=1-s2.0-S2666765724000267-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139993101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, data and knowledge on these contaminants in farmlands are lacking in India, despite being a major agricultural producer worldwide. To date, no studies have explored whether antibiotics are an intractable environmental issue in Indian agroecosystems. Specifically, information on the prevalence and spread of common antibiotics in long-term animal manure-laden organic farmlands of India is non-existent. Here, we examined samples of manure, soil and vegetables collected from 24 different organic farmlands in India to assess the presence of residues from 15 typical veterinary antibiotics (VAs). Our findings revealed that nine VAs, including three tetracyclines (TCs), three sulfonamides (SAs), one macrolide (ML), and two quinolones (QNs), were recorded in almost all the manure and soil samples. The residual levels of antibiotics (µg kg^‒1) decreased in the following order: TCs (manure: 22.10‒161.10; soil: 8.30‒61) &gt; SAs (manure: 0.90‒73; soil: 0.20‒48.40) &gt; QNs (manure: nd‒3.60; soil: nd‒1.80) &gt; MLs (manure: nd‒1.50; soil: nd‒0.90). Poultry manure-applied farmlands exhibited the highest antibiotic contamination levels, with total antibiotic concentrations surpassing the ecotoxicological effect trigger value of 100 μg kg⁻¹ set by the Steering Committee of the Veterinary International Committee on Harmonization, highlighting the potential hazard of VAs to the soil ecosystem. The translocation of VAs in vegetables was in the order: leaf &gt; root &gt; fruit, and bioaccumulation of 0.10‒3.90 μg kg⁻¹ was recorded. Notably, the calculated risk quotients of antibiotics in vegetables were ˂1, indicating the negligible risk to human health. Overall, our study unveils a concerning state of VAs pollution in organic farmlands in India that warrants special attention, as it may contribute to the proliferation of antibiotic resistance.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000279/pdfft?md5=f27a90235ff67afcfe5d74114b48643b&pid=1-s2.0-S2666765724000279-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139998896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, tourists, other outsiders, and the island's growing human population significantly influence the overall standard of the socio-ecological environment, which is narrowly described in existing literature. The research aims to assess the state of the socio-ecological environment, particularly the quality of water, soil,flora and fauna, housing, economic activities, cropping pattern, and key degradation of the island. A questionnaire survey was used to assess housing patterns and ownership, drinking water sources, pollutants, vegetation, cropping patterns, and environmental issues. Furthermore, water samples from coastal regions and tube wells were obtained from 138 sampling points examined in the renowned laboratory of leading Bangladesh Council of Scientific and Industrial Research (BCSIR). Measurements were made of five physiochemical parameters such as pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), arsenic, and chlorine. The profile-based soil and sand samples were assessed based on Organic matter, Total Soluble Salt, pH, and CaCO3. The study found the saltwater along the coast of the island had a range of electrical conductivity from 371 to 7830, TDS from 194 to 8692 ppm, Cl concentration from 0.50 to 2.49 mg/l, arsenic content from 0.00 to 0.49, and pH from 5.50 to 8.09. The findings indicate that semi-brick accounted for 40% of the settlement while brick made up 19.7%, and 37.9% of the settlement was used for residential purposes, and 34.8% of it was made up for commercial purposes (e.g., hotels, resorts, restaurants etc.).

Different analytical techniques were employed to characterize the RHA and MgO-RHA nanocomposites. The prepared adsorbents were used in batch adsorptive studies and the concentrations of the metal ions were measured before and after treatment using atomic absorption spectrophotometry. Morphological analysis confirmed that the adsorbents developed exhibited a dispersed and porous nature. BET analysis revealed that RHA, MgO, and MgO-RHA had surface areas of 93.04, 32.02, and 102.71 m²/g, respectively. MgO-RHA outperforms RHA in removing metal ions due to its increased surface area and functionality. MgO-RHA demonstrated higher removal percentages of up to 79.20 % and 96.02 % for Cr(VI) and Pb(II), respectively. The Pseudo-second order kinetics and Langmuir isotherm demonstrated the highest degree of conformity to the experimental data, considering the coefficient of determination (R²), smallest value of SSE and chi-square (ᵪ2). Thermodynamic results indicated that the adsorption process was characterized by endothermicity, spontaneity and chemisorption controlled.

This work presents an elaborate functional classification and material characterization of plastic packaging in land litter representatively sampled in Flanders, to support policy makers in taking effective reduction measures. In terms of mass, plastic bottles constituted the largest functional fraction (50.4 %) within plastic packaging found in land litter, followed by packaging films (food and non-food combined, 19.2 %) and rigid packaging (food and non-food combined, 18.2 %). In contrast, in number, plastic bottles were only the third largest fraction (10.1 %), after food (37.9 %) and non-food (26.2 %) packaging films. The difference between mass and number % for plastic packaging films can be explained by the fact that these films largely consisted of small and lightweight items, such as cookie wrappers and fragments of torn-open packaging. On a material level, the bottles fraction consisted almost entirely of PET, whereas non-food packaging films, bags and loose bottle caps consisted mainly of PE. ‘Cups and lids’, food and non-food rigid packaging and food packaging films consisted of a variety of polymer types, with PP, PET and PE being the most abundant in different ratios. Given the relative importance of plastic bottles, the introduction of a deposit return system could considerably reduce the plastic packaging mass littered into the environment. However, since the share of plastic packaging in the total collected land litter was only 14 %, the overall effect of such a measure on the litter mass will be limited. Given the high number share of food and non-food packaging films such as cookie wrappers, indicating their high ‘likeliness-to-get-littered’, effective policies to avoid littering of these types of packaging seem to be key.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000231/pdfft?md5=0733e2f838823164ca4b054d26ac6d69&pid=1-s2.0-S2666765724000231-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139975694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These microorganisms could be suitable candidates for treatment of crude oil, aromatic hydrocarbons and the desulfurization of persistent petroleum substances like dibenzothiophene.</p><p>Environmental changes have been analysed with the combination of satellite monitoring and metagenomic in other studies. Red snow phenomenon, in Franz Josef Land's Arctic observed by satellite, is the result of a microbial succession dominated by <em>Chlamydomonas nivalis</em>, a unicellular, red-colored photosynthetic green algae. Similarly, satellite monitoring and metagenomic monitoring were used to assess the impact on coral reefs of a huge quantity of mud spill from iron ore mining on the Abrolhos Bank reef in Brazil.</p><p>In our study, the combination of satellite sensing and metagenomics analyses offer useful tools for the real-time monitoring of water bodies threatened by oil spills, as well as for the design of recovery strategies based on the use of valuable hydrocarbonoclastic microorganisms.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000164/pdfft?md5=f2cfd3ab2f9336c50bd064ba2920d813&pid=1-s2.0-S2666765724000164-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139824699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
