Plastic waste management in rapidly urbanizing regions of the Global South is shaped by informal systems, uneven infrastructure, and governance variability. Addressing this requires moving beyond infrastructure-focused policies to incorporate behavioral determinants. This study develops a behavior-informed decision-support framework for urban plastic waste governance by integrating the COM-B model (Capability, Opportunity, Motivation-Behavior) with the theory of planned behavior (TPB). This approach advances waste behavior modeling by linking structural feasibility with intention formation. Capability and opportunity are captured through COM-B, while the TPB explains how intentions develop. Their combination helps address the intention-behavior gap that remains unresolved in single-focus models. Using survey data from 415 respondents across three cities in Kerala, India, construct validation supported the integrated behavioral framework. Fuzzy DEMATEL analysis identified capability and opportunity as primary causal drivers of motivation and intention, with intention as the strongest predictor of pro-environmental behavior. A Bayesian Network (BN), structured on DEMATEL outputs, was employed to model probabilistic dependencies and simulate intervention scenarios. These indicate that jointly enhancing capability and opportunity increases adoption of core waste-reduction behaviors by approximately 20%, while sustainable purchasing shows only a modest improvement. The findings highlight that effective plastic waste governance requires synergy between motivational interventions and enabling infrastructure to translate intentions into practice. Policy recommendations emphasize strengthening community-based collection systems, expanding decentralized material recovery facilities, and aligning market reforms with local governance structures. This hybrid framework demonstrates how combining causal mapping and probabilistic modeling supports evidence-based and transferable strategies for urban waste management in the Global South.

全球南方快速城市化地区的塑料废物管理受到非正式制度、不平衡的基础设施和治理变化的影响。解决这一问题需要超越以基础设施为重点的政策,纳入行为决定因素。本研究通过将COM-B模型(能力、机会、动机-行为)与计划行为理论相结合,构建了基于行为的城市塑料垃圾治理决策支持框架。该方法通过将结构可行性与意图形成联系起来,推进了废物行为建模。能力和机会是通过COM-B捕获的,而TPB解释意图是如何发展的。它们的结合有助于解决单焦点模型中仍未解决的意图-行为差距。利用来自印度喀拉拉邦三个城市的415名受访者的调查数据,构建验证支持综合行为框架。模糊DEMATEL分析发现能力和机会是动机和意向的主要因果驱动因素,意向是亲环境行为的最强预测因子。采用基于DEMATEL输出的贝叶斯网络(BN)来建模概率依赖关系并模拟干预场景。这些结果表明,共同提高能力和机会使核心减废行为的采用率提高了约20%,而可持续采购仅显示出适度的改善。研究结果强调,有效的塑料废物治理需要动机干预和使基础设施能够将意图转化为实践之间的协同作用。政策建议强调加强以社区为基础的收集系统,扩大分散的材料回收设施,并使市场改革与地方治理结构保持一致。这一混合框架展示了因果映射和概率建模相结合如何支持以证据为基础的、可转移的发展中国家城市废物管理战略。

Potentially toxic elements (PTEs) are persistent environmental contaminants that traverse abiotic compartments and biological kingdoms, producing effects from molecular dysfunction to ecosystem disruption and human health impacts. This review presents a novel, cross-kingdom synthesis of major PTEs—including arsenic, cadmium, lead, chromium, mercury, zinc, and copper—integrating their environmental pathways, cellular and physiological toxicity mechanisms, and ecological and socioeconomic consequences. Essential metals such as copper and zinc become toxic above permissible limits (Cu > 2 mg L1; Zn > 3 mg L1), whereas nonessential metals such as lead and cadmium exert toxicity even at trace levels (Pb > 0.01 mg L1; Cd > 0.003 mg L1). Cross-kingdom commonalities, including oxidative stress, enzyme inhibition and genotoxicity, are highlighted, alongside differences in exposure pathways and trophic transfer, with mercury biomagnifying up to 10-fold in aquatic food webs. Mechanistic endpoints are linked to population- and ecosystem-level impacts. Remediation strategies are reviewed, emphasizing phytoremediation (up to 80% removal efficiency for zinc and cadmium), microbial-assisted approaches, physicochemical treatments, and governance measures. Key research gaps include speciation-aware monitoring, mixture-toxicity studies under realistic exposure scenarios, and long-term, trans-disciplinary investigations connecting molecular biomarkers to ecosystem outcomes. Addressing these priorities will advance evidence-based environmental management, sustainable remediation and provide a comprehensive framework for future cross-kingdom ecotoxicology research.

潜在有毒元素(pte)是一种持久性环境污染物,可穿越非生物隔间和生物王国,产生从分子功能障碍到生态系统破坏和人类健康影响的影响。本文综述了一种新的、跨界合成主要pte的方法,包括砷、镉、铅、铬、汞、锌和铜,整合了它们的环境途径、细胞和生理毒性机制以及生态和社会经济后果。必需金属,如铜和锌,超过允许的限度(Cu > 2 mg L - 1; Zn > 3 mg L - 1)就会产生毒性,而非必需金属,如铅和镉,即使在微量水平(Pb > 0.01 mg L - 1; Cd > 0.003 mg L - 1)也会产生毒性。跨界的共性,包括氧化应激、酶抑制和遗传毒性,以及接触途径和营养转移的差异,汞在水生食物网中的生物放大高达10倍。机械终点与人口和生态系统层面的影响有关。综述了修复策略,重点介绍了植物修复(对锌和镉的去除率高达80%)、微生物辅助方法、物理化学处理和治理措施。关键的研究缺口包括物种意识监测、现实暴露情景下的混合物毒性研究,以及将分子生物标志物与生态系统结果联系起来的长期跨学科研究。解决这些优先事项将推进循证环境管理,可持续补救,并为未来的跨王国生态毒理学研究提供全面的框架。

Water contamination is one of the major issues disturbing the eco-friendly environment that creates a significant impact on human health in addition to the aquatic living organisms, produced due to the rapid industrialization and civilization process. To address this issue in the present study, AgNPs were chemically synthesized for coating on different filters and filter papers to investigate AgNPs activity in the decontamination of domestic water and different industrial wastewater (pharmaceutical industry and polymer industry wastewater). AgNPs were characterized by UV-visible spectroscopy, scanning electron microscope-SEM, and X-ray diffraction-XRD. The UV-Vis spectra showed an absorbance peak in the range of 330 nm. SEM analysis measured the size of AgNPs at about 90 nm and X-Ray diffraction pattern confirmed that the AgNPs are of crystalline nature. The dipping method was used to coat water filters and filter papers with AgNPs filtrates, through which domestic and industrial wastewater were then passed. Non-filtered (control) and filtered water samples were tested for different parameters including pH, electrical conductivity, hardness, nitrates, sulfates, dissolved oxygen, and total dissolved salts. The results demonstrated significant (p < 0.05) reductions in key contaminants, particularly nitrates (up to 96%), electrical conductivity (up to 50%), and total dissolved solids (up to 50%) in industrial wastewater after filtration through AgNP-coated filters compared to uncoated controls. AgNP-coated filters showed higher removal efficiency for selected physicochemical parameters, compared to AgNP-coated filter papers. An increase in dissolved oxygen levels was also observed following filtration, reflecting improved water quality after treatment. This study highlights the novelty of applying AgNP-coated filtration systems specifically to industrial wastewater and provides a direct performance comparison between coated filters and filter papers. The findings suggest that AgNP-coated filters offer a promising and potentially cost-effective approach for industrial wastewater remediation.

由于工业化和文明进程的快速发展,除了水生生物外,水污染是困扰生态环境的主要问题之一,对人类健康产生重大影响。为了解决这一问题,本研究通过化学合成AgNPs并涂覆在不同的过滤器和滤纸上,研究AgNPs对生活用水和不同工业废水(制药工业和聚合物工业废水)的去污活性。采用紫外可见光谱、扫描电子显微镜(sem)和x射线衍射仪(xrd)对AgNPs进行了表征。紫外可见光谱在330nm范围内有一个吸光度峰。扫描电镜(SEM)测量了AgNPs在90 nm左右的尺寸,x射线衍射图证实了AgNPs的结晶性质。采用浸渍法在滤水器和滤纸上涂覆AgNPs滤液,使生活废水和工业废水通过。对未过滤(对照)和过滤后的水样进行了不同参数的测试,包括pH、电导率、硬度、硝酸盐、硫酸盐、溶解氧和总溶解盐。结果表明,与未涂覆agnp的对照组相比,经过镀覆agnp过滤器过滤的工业废水中的主要污染物,特别是硝酸盐(高达96%)、电导率(高达50%)和总溶解固体(高达50%)显著减少(p < 0.05)。与镀agnp滤纸相比,镀agnp滤纸在特定的理化参数下具有更高的去除率。过滤后的溶解氧水平也有所增加,反映了处理后水质的改善。这项研究突出了应用agnp涂层过滤系统专门用于工业废水的新颖性,并提供了涂层过滤器和滤纸之间的直接性能比较。研究结果表明,agnp涂层过滤器为工业废水修复提供了一种有前景且具有潜在成本效益的方法。

In Vietnam, a developing country with rapidly growing industrial activity, small- to medium-scale boilers and waste incinerators are widely used. Absorption systems such as columns or scrubbers are commonly applied for NOx and SO2 removal. A hybrid system that combines existing packed columns with a HiGee contactor is a promising solution for retrofitting existing plants in improving pollution control and practicing carbon capture. This study aims to provide insights into the proposed concept by investigating the flue gas treatment performance of an integrated system comprising a pilot-scaled packed column (PC) and a lab-scaled high-performance rotating reactor. The effect of rotating speed of the HP2R (ω = 100–700 rpm), flue gas flow rate (QG = 25–150 L/min), absorbent flow rate in the PC (QL1 = 0.05–0.35 L/min) and in the HP2R (QL2 = 0.05–0.35 L/min) on the removal efficiency of CO2, SO2, and NOx from simulated flue gas were evaluated in a laboratory-scale setup. The results indicated the enhancement of CO2 and NOx removal efficiencies by approximately 30–50% compared with the standalone PC unit at ω = 500–700 rpm. Continuous operation further confirmed the system's stability in multi-pollutant removal, particularly for SO2 and NOx, although CO2 capture performance was found to be sensitive to absorbent pH, emphasizing the need for effective absorbent regeneration to sustain long-term operation.

越南是一个工业活动迅速发展的发展中国家,广泛使用中小型锅炉和垃圾焚烧炉。吸收系统如塔或洗涤器通常用于NOx和SO2的去除。将现有填料塔与high接触器相结合的混合系统是改造现有工厂以改善污染控制和实践碳捕获的有希望的解决方案。本研究旨在通过研究由中试规模填料塔(PC)和实验室规模高性能旋转反应器组成的综合系统的烟气处理性能,为所提出的概念提供见解。在实验室条件下,研究了HP2R转速(ω = 100-700 rpm)、烟气流量(QG = 25-150 L/min)、PC吸收剂流量(QL1 = 0.05-0.35 L/min)和HP2R吸收率(QL2 = 0.05-0.35 L/min)对模拟烟气中CO2、SO2和NOx去除效率的影响。结果表明,在ω = 500-700 rpm时,与独立PC装置相比,CO2和NOx去除效率提高了约30-50%。连续运行进一步证实了该系统在多种污染物去除方面的稳定性,特别是对SO2和NOx,尽管CO2捕获性能对吸收剂的pH值很敏感,强调了有效的吸收剂再生以维持长期运行的必要性。

Cellulases are essential enzymes for breaking down lignocellulosic biomass in second-generation ethanol production, but their high cost limits widespread use. Solid-state fermentation (SSF) offers a cost-effective alternative by producing high enzyme yields from agro-industrial residues. This study investigated cellulase production by Aspergillus fumigatus using coffee husks, both untreated and pretreated via combined alkaline and microwave methods, as carbon sources. The effects of initial moisture (50%–70%) and husk content (60%–80%) on SSF were optimized through response surface methodology. The crude enzymatic extract was biochemically characterized for optimal pH (3–8), temperature (30–70°C), thermal stability, and metal ion effects. Pretreated husks increased enzyme activity (FPase) by 121%, confirming improved cellulose accessibility. The extract showed optimal activity at pH 5–6, stability between 40°C and 60°C, and enhanced performance with Cu2+, Co2+, and Mn2+. When applied to hydrolysis of pretreated coffee husks, the extract achieved 27 mg/g conversion after 48 h, demonstrating its effectiveness. These results indicate that coffee husk serves both as an inducer of fungal cellulase production and as a lignocellulosic feedstock, emphasizing its biotechnological potential for sustainable biomass valorization.

纤维素酶是第二代乙醇生产中分解木质纤维素生物质的必需酶,但其高昂的成本限制了其广泛应用。固态发酵(SSF)提供了一种具有成本效益的替代方法,可以从农业工业残留物中产生高酶产量。本研究研究了烟曲霉以未经处理和经碱性和微波联合处理的咖啡壳为碳源生产纤维素酶。通过响应面法优化初始水分(50% ~ 70%)和谷壳含量(60% ~ 80%)对籽粒SSF的影响。对粗酶提取物进行了生物化学表征,确定了最佳pH(3-8)、温度(30-70℃)、热稳定性和金属离子效应。预处理后的稻壳使酶活性(FPase)提高了121%,证实改善了纤维素的可及性。提取液在pH值5 ~ 6时活性最佳,在40 ~ 60℃范围内稳定性较好,在Cu2+、Co2+和Mn2+中性能较好。当应用于预处理咖啡壳的水解时,提取物在48小时后达到27 mg/g的转化率,证明了它的有效性。这些结果表明,咖啡壳既可以作为真菌纤维素酶生产的诱导剂,也可以作为木质纤维素原料,强调了其可持续生物质增值的生物技术潜力。

This study examines how adaptive capacity indicators influence residents’ willingness to participate (WTP) in community-based sanitation programs in Koja, North Jakarta, focusing on slum and non-slum communities. A structured survey of 400 individuals was conducted, and the data were analyzed using importance-performance analysis (IPA) and binary choice models, including probit and logit regressions. The IPA results revealed that slum residents showed critical performance gaps in key adaptation indicators such as Asset2 (waste treatment), Flexibility1 (monitoring systems), and Agency2 (community advocacy)—indicating low-priority but essential adaptation needs. In contrast, non-slum residents reported higher importance and performance scores across most indicators, including Agency1, Organization1, and Learning2, suggesting better adaptive capacity. Regression findings confirmed that non-slum residency (β = 0.465–0.787, p < 0.05), homeownership (β = 0.640–1.149, p < 0.01), female gender (β = 0.437–0.844, p < 0.01), and age above 39 (β = 0.319–0.568, p < 0.05) significantly increase the probability of WTP. The perceived importance of adaptation services was also a significant positive predictor (β = 0.535–0.964, p < 0.01), while the performance of adaptation services was not statistically significant. These results highlight that sociodemographic factors and perceived importance are stronger motivators than service performance alone. The study underscores the value of integrating adaptive capacity dimensions—assets, flexibility, organization, learning, and agency—into sanitation planning to ensure equity and justice in urban ecosystem services. By combining IPA and econometric models, this research provides a replicable framework for identifying priority areas and vulnerable populations.

本研究考察了适应能力指标如何影响雅加达北部Koja地区居民参与社区卫生项目的意愿,重点关注贫民窟和非贫民窟社区。对400名个体进行了结构化调查,采用重要性-绩效分析(IPA)和二元选择模型,包括probit和logit回归,对数据进行了分析。IPA结果显示,贫民窟居民在关键适应指标(如Asset2(废物处理)、Flexibility1(监测系统)和Agency2(社区宣传))方面存在严重的绩效差距,这表明适应需求的优先级较低,但却至关重要。相比之下,非贫民窟居民在大多数指标(包括Agency1、Organization1和Learning2)上的重要性和表现得分更高,表明他们有更好的适应能力。回归结果证实,非贫民窟居住(β = 0.465-0.787, p < 0.05)、住房拥有率(β = 0.40 - 1.149, p < 0.01)、女性(β = 0.437-0.844, p < 0.01)和年龄(β = 0.319-0.568, p < 0.05)显著增加WTP的概率。感知适应服务的重要性也是显著的正预测因子(β = 0.535-0.964, p < 0.01),而适应服务的绩效无统计学意义。这些结果强调社会人口因素和感知重要性是比服务绩效本身更强的激励因素。该研究强调了将适应能力维度(资产、灵活性、组织、学习和代理)纳入卫生规划的价值,以确保城市生态系统服务的公平和公正。通过结合IPA和计量经济学模型,本研究为确定重点地区和弱势群体提供了一个可复制的框架。研究结果为有针对性的基础设施改善和行为改变战略提供了政策指导,特别是在服务不足的贫民窟地区。这种综合方法有助于发展符合可持续发展目标3、6、10和11的公正、包容和可持续的环境卫生系统。

A structured survey of 400 individuals was conducted, and the data were analyzed using importance-performance analysis (IPA) and binary choice models, including probit and logit regressions. The IPA results revealed that slum residents showed critical performance gaps in key adaptation indicators such as Asset2 (waste treatment), Flexibility1 (monitoring systems), and Agency2 (community advocacy)—indicating low-priority but essential adaptation needs. In contrast, non-slum residents reported higher importance and performance scores across most indicators, including Agency1, Organization1, and Learning2, suggesting better adaptive capacity. Regression findings confirmed that non-slum residency (<i>β</i> = 0.465–0.787, <i>p</i> &lt; 0.05), homeownership (<i>β</i> = 0.640–1.149, <i>p</i> &lt; 0.01), female gender (<i>β</i> = 0.437–0.844, <i>p</i> &lt; 0.01), and age above 39 (<i>β</i> = 0.319–0.568, <i>p</i> &lt; 0.05) significantly increase the probability of WTP. The perceived importance of adaptation services was also a significant positive predictor (<i>β</i> = 0.535–0.964, <i>p</i> &lt; 0.01), while the performance of adaptation services was not statistically significant. These results highlight that sociodemographic factors and perceived importance are stronger motivators than service performance alone. The study underscores the value of integrating adaptive capacity dimensions—assets, flexibility, organization, learning, and agency—into sanitation planning to ensure equity and justice in urban ecosystem services.

This study evaluated the ability of the red microalga Porphyridium cruentum in removing polyethylene terephthalate (PET) microplastics (MPs) from aquatic systems through a hetero-aggregation mechanism mediated by exopolysaccharides (EPS). Results showed that PET MPs exposure to microalgae at concentrations of 100, 200, and 300 mg/L for 30 days notably reduced microalgae growth at higher concentrations. Conversely, increased PET MPs concentration increased EPS production by microalgae as a defense response to oxidative stress. The highest EPS production was obtained at a 300 mg/L PET MPs exposure, concentration of 4.349 g/L. FTIR analysis showed EPS was rich in negatively charged carboxyl and sulfate groups, electrostatically interacting with positively charged PET MPs, forming stable flocculating hetero-aggregates. The removal efficiency of PET MPs reached 95.8%–97.5%, with the highest efficiency obtained at a concentration of 200 mg/L PET MPs, demonstrating the effectiveness of P. cruentum in removing PET MPs from water environment. SEM analysis confirmed the formation of a solid EPS matrix encasing the MPs particles and the absence of markedly structural changes in the EPS post-interaction confirmed through FTIR. These findings underscore the potential of microalgae as an eco-friendly and energy-efficient biological solution for MPs remediation in aquatic environments.

本研究评估了红微藻卟啉(Porphyridium cruentum)通过外多糖(EPS)介导的异聚集机制从水生系统中去除聚对苯二甲酸乙二醇酯(PET)微塑料(MPs)的能力。结果表明,PET MPs分别以100、200和300 mg/L的浓度暴露于微藻中30天,显著降低了高浓度微藻的生长。相反,增加PET MPs浓度会增加微藻对氧化应激的防御反应EPS的产生。当PET MPs浓度为4.349 g/L时,EPS产量为300 mg/L。FTIR分析表明,EPS富含带负电荷的羧基和硫酸盐基团,与带正电荷的PET MPs静电相互作用,形成稳定的絮凝异聚集体。PET MPs的去除率可达95.8% ~ 97.5%,其中在PET MPs浓度为200 mg/L时去除率最高,说明了金盏花对水中环境中PET MPs的去除效果。SEM分析证实形成了包裹MPs颗粒的固体EPS基质,FTIR证实EPS相互作用后没有明显的结构变化。这些发现强调了微藻作为水生环境中MPs修复的生态友好和节能的生物解决方案的潜力。

This study proposes and applies the Environmental Paper Industry Performance Indicator (EPIPI), a sector-specific composite indicator for assessing the environmental performance of pulp and paper production based on process-related wastes. EPIPI integrates results from the ReCiPe life cycle impact assessment method (ReCiPe), Life Cycle Assessment (LCA), Improved Analytic Hierarchy Process (IAHP) weights, and operational waste data (annual mass, spatial dispersion, and disposal adequacy) into a single measure expressed in weighted kilograms per year (w·kg/year). The indicator was applied to an integrated pulp and paper mill in Brazil, using data on waste composition, generation, and management practices. The final EPIPI value was 9.097×107 w·kg/year, very close to the theoretical worst-case value of 9.138×107 w·kg/year, which would occur if all wastes were improperly managed; thus, only 0.45% of the weighted waste was effectively managed in an environmentally appropriate way, indicating poor environmental performance. Atmospheric emissions accounted for approximately 99% of the EPIPI score and about 35% of the total weighted impact, largely due to their high annual volume and wide spatial dispersion, despite being legally permitted. Ashes ranked second in weighted impact but contributed less than 1% to the EPIPI value because of their lower mass. Other wastes—such as secondary sludge, lime mud, primary sludge, dregs, and eucalyptus bark—showed high impact potentials but did not contribute to the EPIPI score because they were composted, reused, or otherwise managed in environmentally appropriate ways (k = 0). The results demonstrate that EPIPI can distinguish between potential impact and effectively mismanaged wastes, helping prioritize critical waste streams (especially atmospheric emissions from recovery boilers, biomass boilers, and lime kilns) and supporting targeted improvement actions in the pulp and paper industry.

本研究提出并应用了环境造纸行业绩效指标(EPIPI),这是一个针对特定行业的复合指标,用于评估纸浆和造纸生产过程相关废物的环境绩效。EPIPI将ReCiPe生命周期影响评估方法(ReCiPe)、生命周期评估(LCA)、改进层次分析法(IAHP)权重和运营废物数据(年质量、空间分散和处置充分性)的结果整合为一个单一的度量,以加权公斤/年(w·kg/年)表示。该指标应用于巴西的一家综合纸浆和造纸厂,使用了有关废物组成、产生和管理做法的数据。最终的EPIPI值为9.097×107 w·kg/年,非常接近理论最坏值9.138×107 w·kg/年,这是所有废物管理不当都会发生的;因此,只有0.45%的加权废物得到了环境适宜的有效管理,表明环境绩效较差。大气排放约占EPIPI得分的99%,约占总加权影响的35%,这主要是由于它们的年排放量高,空间分布广,尽管法律允许。灰烬在加权影响中排名第二,但由于其质量较低,对EPIPI值的贡献不到1%。其他废物,如二次污泥、石灰泥、一次污泥、渣滓和桉树树皮,显示出很高的影响潜力,但对EPIPI评分没有贡献,因为它们被堆肥、再利用或以其他方式以环境适当的方式管理(k = 0)。结果表明,EPIPI可以区分潜在影响和有效管理不善的废物,帮助确定关键废物流(特别是回收锅炉、生物质锅炉和石灰窑的大气排放)的优先级,并支持纸浆和造纸行业的有针对性的改进行动。

Water quality is a stern issue in urban areas because it is indispensable for the sustenance of life. The present study aimed to determine the spatial trends with time in water quality attributed to transitioning anthropogenic land-use/cover in a Himalayan city—Dehradun, India—through the Weighted Arithmetic Water Quality Index (WQI). A total of 36 samples from nine surface aquifers during four seasons were analyzed for physicochemical and biological water quality parameters and compared with standards prescribed by BIS—Bureau of Indian Standards and WHO—World Health Organization. The water quality categorization during the monsoon (good–moderate), post-monsoon (poor–very poor), and the winter and premonsoon seasons (poor–unfit) reveals the temporal trends. Further, WQI values indicate that 25% of the water samples (urban) were in the very poor–unfit category, 52% in poor (semi-urban), and 22.2% in good status (rural), with elevated values for Coliform bacteria at all locations. Unsustainable anthropogenic activities, namely, discharge of wastewater, indiscriminate dumping of solid waste, and fecal matter, are the main factors, which have negatively impacted the water quality of these rivulets. Land-cover analyses from 2002 to 2023 observed an increase in settlement—urban built-up (+7.5%), cultivated land (+7.5%), and barren land (+4.4%), whereas grassland (−8%), forest (−12%), and water bodies (−0.11%) decreased in terms of area coverage, with a slight decline in land surface temperature regimes attributed to the aerosol optical depth variations. The management of water resources (catchment basin conservation) in the Dehradun region is a major concern pertaining to urban land use planning and the mandate of Sustainable Development Goals (SDGs) 6 and 11.

水的质量是一个严峻的问题在城市地区,因为它是不可或缺的生命的维持。本研究旨在通过加权算术水质指数(WQI)确定印度德拉敦喜马拉雅城市人为土地利用/覆盖过渡的水质空间趋势。在四个季节对九个地表含水层的36个样本进行了物理化学和生物水质参数分析,并与bis -印度标准局和世卫组织-世界卫生组织规定的标准进行了比较。季风期(良好-中等)、季风后期(差-很差)、冬季和季风前期(差-不适宜)的水质分类揭示了时间趋势。此外,WQI值表明,25%的水样(城市)处于非常差不适合的类别,52%的水样处于差(半城市)类别,22.2%的水样处于良好状态(农村),所有地点的大肠菌群值均升高。不可持续的人为活动,即排放废水、随意倾倒固体废物和粪便,是对这些溪流水质产生负面影响的主要因素。从2002年到2023年的土地覆盖分析中发现,住区-城市建成区(+7.5%)、耕地(+7.5%)和荒地(+4.4%)的面积覆盖增加,而草地(- 8%)、森林(- 12%)和水体(- 0.11%)的面积覆盖减少,地表温度的轻微下降归因于气溶胶光学深度的变化。德拉敦地区的水资源管理(集水区保护)是与城市土地利用规划和可持续发展目标6和11相关的一个主要问题。

This study presents an ecological and geochemical assessment of trace element contamination in the Huyva River (Ukraine), a right tributary of the Teteriv River that supplies drinking water to Zhytomyr and nearby settlements. The research involved monitoring key physicochemical parameters, including pH, mineralization, hardness, and major ion composition, to evaluate seasonal and spatial hydrochemical variations. Concentrations of trace elements in water and bottom sediments were analyzed for 2014 and 2024, covering Ba, Pb, Ti, Mn, Cr, Ni, V, Cu, Ag, Li, Cd, Co, and Zn. Pollution was quantified using Contamination Factor (CF), Contamination Degree (CD), Overall Pollution Index (Zc), and Geo-accumulation Index (Igeo). The results revealed an increase in Mn, Cu, Pb, and Co levels in sediments and a general rise in overall pollution, attributed to anthropogenic activities, hydrological alterations, and climatic factors—notably higher temperatures and lower oxygen levels that enhance metal mobility. The study also evaluated potential stabilization strategies for heavy metals, including physicochemical, biological, and engineering methods. Among them, natural carbonate materials were identified as the most effective due to their environmental compatibility, affordability, and ability to operate near water intake areas without disturbing water treatment systems, supporting sustainable water quality management.

本研究提出了Huyva河(乌克兰)微量元素污染的生态和地球化学评估,Teteriv河的右支流为日托米尔和附近的定居点提供饮用水。该研究包括监测关键的物理化学参数,包括pH、矿化、硬度和主要离子组成,以评估季节和空间的水化学变化。分析了2014年和2024年水体和底泥中微量元素Ba、Pb、Ti、Mn、Cr、Ni、V、Cu、Ag、Li、Cd、Co和Zn的浓度。采用污染因子(CF)、污染程度(CD)、总污染指数(Zc)和地积指数(Igeo)对污染进行量化。结果显示,由于人为活动、水文变化和气候因素,特别是高温和低氧水平增强了金属的流动性,沉积物中锰、铜、铅和钴的含量增加,总体污染程度普遍上升。该研究还评估了重金属的潜在稳定策略,包括物理化学,生物和工程方法。其中,天然碳酸盐材料被认为是最有效的,因为它们具有环境兼容性、可负担性,并且能够在取水区附近运行,而不会干扰水处理系统,支持可持续的水质管理。
