While many research efforts have focused on biodegradable plastics derived from starch-rich food sources such as potato, corn, and rice, the use of agricultural byproducts as a cellulose source has not been thoroughly explored. Hence, this research delves into the creation of biodegradable bioplastic films using cellulose derived from discarded coconut shell powder, a by-product rich in lignocellulose with considerable value. Bioplastic films were produced by solution casting, with cellulose mixed with gelatin, glycerol, citric acid, and distilled water in varying ratios. The films were extensively assessed for their physical, mechanical, thermal, surface, morphological, and biodegradation properties. The highest tensile strength attained was 8.22 ± 0.10 MPa, and the maximum bursting strength was 0.19 ± 0.01 MPa. The films also exhibited favorable thickness properties, improved biodegradability, and better water contact angles, suggesting their suitability for packaging applications. Morphological and thermal examinations additionally verified the structural soundness and steadiness of the produced films. The innovation in this research centers on the use of discarded coconut shell powder as an eco-friendly cellulose source for the manufacture of biodegradable packaging films. By converting abundant agricultural waste into value-added bioplastic materials, this study supports waste reduction, resource conservation, and the development of eco-conscious alternatives to traditional plastic packaging.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"36 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148816626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focusing on the Tamiraparani River Basin (TRB), this research evaluates soil health and pollution status by systematically collecting and analyzing 39 samples to measure key chemical parameters and specific metal concentrations. While the TRB faces escalating pressure from intensive agriculture and industrialization, a comprehensive assessment linking land-use-specific metal accumulation remains largely absent; this study addresses this gap by pairing high-resolution spatial mapping with pollution assessment. Conventional techniques were utilized to determine attributes like pH, electrical conductivity, and trace element levels. The contamination degree spanned from 6.47 to 14.54, with four locations recording minimal contamination while the rest displayed moderate levels. Meanwhile, Pollution Load Index metrics fluctuated from 0.73 to 1.26, with 16 locations pointing to a gradual decline in soil health driven by human activities. Overall, the results point to minimal overall contamination accompanied by slight localized enrichment, highlighting the necessity for proactive environmental monitoring. Consequently, these localized PLI elevations highlight critical zones requiring immediate source-specific management to arrest further catchment degradation. This baseline assessment provides a transferable geochemical framework to identify early-stage soil deterioration, enabling targeted land-use interventions before marginal enrichment transitions into widespread eco-toxicological and public health liabilities.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"36 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a risk-informed Geographic Information System (GIS)-based multi-criteria decision analysis (MCDA) framework for landfill site selection in Edirne Province. Edirne represents a highly constrained decision space due to its low-lying topography, floodplain dynamics, dense river networks, and intensive agriculture. Using the Analytic Hierarchy Process (AHP), the framework integrates eight key criteria: flood susceptibility, river proximity, slope, elevation, land use/land cover (LULC), geological structure, soil characteristics, and accessibility. Results reveal that moderate suitability areas dominate the province (64.1%), followed by high (21.9%) and low (12.4%) suitability. Very high suitability areas are severely restricted, covering only 0.8% (52.3 km²) and emerging as fragmented patches where favorable conditions intersect. This spatial scarcity is primarily driven by critical environmental bottlenecks, specifically compatible LULC (0.4%), suitable geology (4.8%), and low-permeability soils (3.9%), which collectively exert a strong spatial filtering effect. Ultimately, this structured GIS-MCDA screening approach informs sustainable waste management planning in environmentally constrained regions. The severe limitation of highly suitable land demonstrates that conventional landfill expansion is spatially restrictive. The findings underscore the urgent need for strategies aligned with Sustainable Development Goals (SDGs 6 and 11), emphasizing surface and groundwater protection, resource recovery, recycling, and a critical transition away from landfill-dependent waste systems.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"36 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the fracture scale, fractures may enhance heat transfer or induce thermal short-circuiting depending on their connectivity and evolution. At the field scale, subsurface heterogeneity, ice content and operational parameters jointly determine heating efficiency and contaminant removal.

The estimated mass of MPs entering the water of the Gulf ranged from 155 to 413.4 kt per year. This review synthesizes peer-reviewed studies published between 2010 and 2024, covering seawater, sediments, and biota. Reported concentrations vary considerably: seawater ranged from 0–3 MPs/m³ in Qatar to 12,000 MPs/m3 in Kuwait, while sediments concentrations reached up to 665 MPs/kg in Oman and as many as 195,104 particles at Iranian hotspots. In biota, MPs were frequently detected in fish and prawns, with up to 828 particles recorded in digestive tracts and 18.5 MPs/10 g in edible muscle tissues. Fibers and fragments dominate across all matrices, with polyethylene (PE) and polypropylene (PP) as the most common polymers. Furthermore, legislation and regulations available on the regional and national level to reduce the amount of marine litter including plastics and MPs were discussed. Microplastics in the Gulf are examined across four themes: (1) source and pathway, (2) classification, (3) occurrence and fate, and (4) environmental impacts and future risks. Cross-study comparison reveals spatial and temporal variability, contradictory biotic load estimates across countries, and significant methodological inconsistencies that limit data comparability. Critical knowledge gaps persist, including the absence of Gulf-specific studies on lower trophic levels, ecotoxicological thresholds, and quantitative human exposure models. Although Gulf states have introduced measures such as single-use plastic bag bans, legislation remains fragmented, compliance data are scarce, and certain policy approaches (notably the reliance on oxo-degradable plastics) are inconsistent with international best practice. The Gulf's distinctive characteristics including its semi-enclosed hydrology, extreme salinity and temperature, and shared governance challenges position it as both a natural laboratory for studying microplastic fate and transport and a potential testbed for regional policy harmonization.

This study investigated seasonal and diurnal variations in indoor air quality (IAQ) across AC and Non-AC environments in Mymensingh, assessing compliance, pollutant correlations, and quantification of health risks (ELCR, HQ). Measurements of PM₁, PM_2.5, PM₁₀, TVOCs, HCHO, temperature, and humidity were taken from 56 rooms (28 AC, 28 Non-AC) during the monsoon and post-monsoon seasons using real-time monitors. During the post-monsoon season, PM_2.5 levels in Non-AC rooms reached 123.29 µg/m³ in the afternoon, compared to 79.79 µg/m³ in AC rooms, while PM₁₀ concentrations peaked at 145.32 µg/m³ in Non-AC environments and 89.75 µg/m³ in AC rooms. TVOC levels were highest in AC rooms, reaching 884 µg/m³, likely due to limited ventilation, and HCHO concentrations in AC spaces (301.14 µg/m³) consistently exceeded WHO guidelines. Temperature and humidity influenced pollutant dynamics, with PM levels positively correlated with temperature and HCHO negatively correlated.
