Improper disposal methods contribute to environmental degradation, including disruptions to aquatic ecosystems and the spread of antimicrobial resistance. Despite these growing concerns, a comprehensive review of pharmaceutical waste management and disposal practices is still lacking. To address this gap, a scoping review was conducted, analyzing 4269 records from three databases (Medline OVID, Web of Science, and Embase) and grey literature, with 67 studies ultimately included. The initial records were identified through a comprehensive search across the aforementioned databases using a structured strategy based on three core concepts: medication waste, disposal methods, and environmental or human health impacts. This was followed by a two-stage screening process guided by the PCC framework and predefined inclusion criteria. The review aims to assess disposal practices and their impacts, identify research gaps, and guide future research toward effective strategies for managing pharmaceutical waste while protecting ecological balance and public health. The publications timeline shows increasing interest in the topic, particularly with a surge in studies during 2022 and 2023. The findings reveal a significant regulatory gap, especially in the Global South, where limited infrastructure and public awareness lead to reliance on household waste disposal. In contrast, medication take-back programs are more common in the Global North. This disparity underscores the urgent need for policy development. Addressing pharmaceutical waste effectively requires coordinated efforts from the pharmaceutical industry, healthcare providers, regulatory bodies, and local communities. Key strategies should include regulatory action, public education, technological innovation, and addressing issues like drug misuse and overconsumption, particularly of antibiotics, which contribute to antimicrobial resistance. A holistic approach is essential to mitigate both environmental and public health risks.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 6","pages":"1388 - 1400"},"PeriodicalIF":2.7,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 concentration of heavy metals in soil is influenced not only by inherent soil properties but also by geographical factors.

Previous studies primarily focused on single-factor identification and spatial distribution characterization, neglecting the characteristics and spatial features of soil heavy metal concentration under the interactive effects of geographical factors and soil properties. This study assessed the influence of geographical factors, soil properties, and their interactive effects on the spatial distribution of soil arsenic (As), in a typical arsenic-contaminated paddy field area by employing machine learning, analysis of variance, and spatial analysis methods. The findings show that the prediction performance (R<sup>2</sup>) of the random forest model for soil As concentration was 0.596, and the primary factors influencing the distribution of soil As are elevation, roads, rivers, soil pH, and cation exchange capacity (CEC). Moreover, the interactive effect between elevation and soil CEC had a significant effect on soil As (p < 0.05), exhibiting spatially homogeneous characteristics. The interactive effect between rivers and both soil pH and soil CEC exhibited spatially heterogeneous effects on soil As (p < 0.1). Additionally, the interactive effect between roads and soil pH affected soil As (p < 0.05), with spatially homogeneous characteristics. By identifying the main influencing factors of As in paddy soil, this study further explores the variation characteristics of soil As concentration under the interactive effects of geographical factors and soil properties. These insights can serve as a valuable reference for the precise prevention of As pollution in paddy field area.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 spatial explanatory power of landscape element for VAI was better than that of landscape pattern characteristics, while the combined factors in landscape structure all explained VAI better than univariate. The response of FVC to landscape structure was more significant compared to NPP. The high value areas of FVC tended to occur in natural landscape elements. FVC showed spatial correlation and clustering characteristics with both PD and LPI. One or more thresholds existed in the response of FVC to changes in landscape pattern.

Methylene blue which is considered as mutagenic, toxic, and non-biodegradable, was selected as a model in this study to represent the azo-dye class. The undesired effects of dye contamination can be eliminated through the sustainable and eco-friendly remediation procedure of photocatalytic degradation. The properties and efficiency of the catalytic reaction are significantly influenced by the morphology of the catalyst. Mott Schottky measurements and chronoamperometry were employed to elucidate the electronic properties of a composite silver humic acid magnetic nanoparticle (Ag/HA MNP) with a core-shell structure. The nanoparticle was subsequently employed in the photocatalytic degradation of methylene blue. The indirect band gap energy was calculated as 1.82 eV by employing Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-DRS). The optimal parameters established in the study were used to maintain the effective photocatalytic degradation of methylene blue in an aqueous medium. Optimization studies for photocatalytic degradation of model dye-MB showed that the optimum degradation percentage (42%) was achieved rapidly in a short time period of 30 min with 0.06 g MNP in 10 mgL<sup>-1</sup> solution.

This presents a challenge to end-users when selecting tool(s) to integrate within HAB surveillance programs. In response, we conducted a multi-year, side-by-side comparison study between qPCR and SHA relative to microscopy for monitoring the raphidophyte <i>Heterosigma akashiwo</i>, a species responsible for fish kills and impaired water quality worldwide. This paper summarizes key findings from a broad suite of side-by-side, laboratory and field tests of <i>H. akashiwo</i> cell quantification by qPCR and SHA. Assay ranges, detection limits, applicability to preserved samples, and physiological conditions (time of day, growth phase, nutrient levels) of cultured <i>H. akashiwo</i> revealed generally strong qPCR-SHA agreement, though qPCR had a wider dynamic range (without homogenate dilution) while SHA displayed a lower detection limit. Both assays yielded excellent agreement with microscopy during cell growth in the laboratory as well as during bloom development in the field. However, qPCR and SHA cell abundance data were less than microscopy during stationary-decline growth and under low nitrate, indicating reduced cellular nucleic acid during senescence and nutrient stress. Pragmatically, both qPCR and SHA are affordable, but qPCR solutions are typically more available commercially than SHA.

Therefore, this study aims to assess the capacity of actors to take ownership of and lead the governance processes implied by the CREMA approach.

The lack of knowledge and technical skills to support multi-actor processes, the weak collaboration between actors, and the lack of sustainable financial inflows and livelihood support are key challenges to be addressed for better CREMA performance. Despite these constraints, local actors’ enthusiasm and willingness to engage more actively in the governance of their landscape constitute an opportunity for an improved implementation of the CREMA approach. We suggest that initiatives to strengthen the technical and financial capacities of governance bodies and raise awareness among the local population are necessary to improve the functioning and performance of CREMAs.
