A bibliometric analysis of scientific publications in the Scopus and Web of Science databases for the period 2014-2023 was conducted using VOSviewer visualization and data processing methods. The analysis identified the main areas of research and gaps in knowledge that are relevant to the future application of this technology in Ukraine. Moreover, remote sensing methodologies were employed to identify potential remediation requirements in the Ukrainian territory. This involved the analysis of changes in the normalized difference vegetation index (NDVI) and the normalized difference moisture index (NDMI) of a part of Ukraine's agricultural territory situated along the frontline, prior to and following a period of three years during a full-scale war. The results revealed changes in vegetation and moisture levels, indicating land degradation in the border area under study.

This study sought to evaluate the performance of a local wastewater treatment plant (WWTP) in the removal of selected metals, perform mycofiltration on the wastewater, and assess metal removal in the filtrate. Wastewater influent and effluent samples were collected and analysed for Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), Aluminium (Al), Arsenic (As), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Iron (Fe), Lead (Pb), Manganese (Mn), Mercury (Hg), Molybdenum (Mo), Nickel (Ni), Phosphorus (P), Selenium (Se), Titanium (Ti) and Zinc (Zn). A Pleurotus ostreatus mycofilter was cultured and packed into Pyrex columns (3.3 x 15 cm). Wastewater samples were mycofiltered at a constant flow rate, and metal removal efficiency was assessed. The wastewater quality index (WWQI) was also calculated. The WWTP performed poorly, as only Na, Fe, and P had lower levels in the effluent compared to the influent. There were no changes between influent and effluent metal concentrations for most metals. After mycofiltration of the wastewater influent, P, Hg, Na, Fe, K and Cu were removed with an efficiency of 99%, 50%, 48%, 31%, 30%, and 23%, respectively. Mycofiltration of the wastewater effluent removed P, K, Pb, Hg and Fe with an efficiency of 99%, 52%, 51%, 51% and 10%, respectively. Mycofiltration could not remove metals such as Ca, Cr and Cd. The WWQI for the WWTP effluent, the mycofiltered influent and the mycofiltered effluent were 604.6, 582.2, and 548.0, respectively.

Given the dependency of Zn toxicity to aquatic organisms on local water body conditions, it is essential that the derivation of Environmental Quality Standards (EQS) for Zn incorporates bioavailability. We have updated the Zn EQS by revising and updating the existing ecotoxicity dataset and by including optimized bioavailability models. Adhering to the existing EQS derivation guidance, a new bioavailability-based EQS (EQSbioavailable) was derived for Europe. The updated chronic Zn freshwater ecotoxicity dataset contains high-quality data covering 40 species and covers the minimum data requirements for species sensitivity distribution-extrapolation set out in the WFD-guidance. The existing chronic Zn bioavailability models for invertebrates, vertebrates and algae were revised by optimizing their structure and by using the most recent version of WHAM (version VII) as the underlying speciation software. The updated models were validated with independent data for ten aquatic species. Zinc toxicity at regulatory relevant effect concentrations (e.g., 10% effect concentrations) were predicted within 2-fold error for most species, for one species within 3-fold error. Hence, the updated bioavailability models were used to predict Zn toxicity reliably across different species. The updated ecotoxicity dataset and chronic bioavailability models were combined with species sensitivity distribution techniques resulting in the updated Zn EQS derivation approach. This approach was used to derive a scientifically robust bioavailable EQS for Zn in European freshwaters based on the latest available technical guidance. The resulting EQSbioavailable of 11.2 µg dissolved Zn/L refers to conservative conditions and can serve as a first-tier screening level in compliance assessments under the WFD. In addition, the updated Zn EQS derivation approach developed in the current study will increase the ecological and ecotoxicological relevancy of higher screening levels by allowing incorporation of local bioavailability considerations.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149181495","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}

Steroid hormones used in hormonal contraception are widely detected in aquatic environments, raising concerns regarding their ecotoxicological risks. This review synthesizes environmental impacts of registered (non-)hormonal contraceptives, aiming to compare their environmental sustainability and estimate comparative ecotoxicological risk profiles of hormonal methods. A systematic literature search of Medline, Embase, Web of Science Core Collection, and Scopus was conducted through January 8, 2026, covering life cycle assessments, carbon footprint studies, water monitoring studies, chronic ecotoxicological effect studies, and environmental risk assessments. Of 3,409 records retrieved, 78 studies met predefined inclusion criteria. Extracted data were organised by study type, contraceptive method, environmental impact categories, and ecotoxicological endpoints. Available life cycle assessments were limited to condoms and showed that natural rubber condoms were associated with lower production-related environmental burden than polyisoprene condoms. The total waste associated with the use of long-acting hormonal contraceptives was lower compared to short-acting methods and non-hormonal intrauterine devices. Environmental risk assessments revealed global occurrence of estrogens and progestins in surface waters, with some posing risks to aquatic ecosystems. Comparative ecotoxicological profiles suggested lower relative ecotoxicity for drospirenone- and desogestrel-containing oral contraceptives per daily dose compared with other hormonal methods, and potentially lower ecotoxicity for levonorgestrel intrauterine devices compared to levonorgestrel containing oral formulations. Overall, the included studies reported on only a limited range of environmental impacts, such as waste production, carbon footprint and ecotoxicity, while overlooking other aspects of environmental sustainability. Because of this no definitive conclusions or comparisons could be made based on the full environmental sustainability. However, by extending the focus beyond direct environmental impacts towards overall sustainability, different contraceptive groups were ranked according to their overall sustainability. This led to the conclusion that long-acting reversible contraceptives are relatively more sustainable then short-acting reversible methods.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167006","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}

Interpretation of degradation studies using more complex conditions compared to the single-compound standard studies may be difficult in terms of considering the variability of the underlying laboratory datasets. This work demonstrates a benchmarking and interpretation framework that uses regulatory reference datasets to evaluate whether experimentally determined DT50 values fall within experimental variability, illustrated through a multi-pesticide co-spike degradation case study. Degradation of a mixture of twelve pesticides (acetamiprid, azoxystrobin, bentazon, boscalid, chloridazon, dimethenamid-P, fenhexamid, metazachlor, metobromuron, mesosulfuron-methyl, propamocarb, and terbuthylazine) was investigated in seven agricultural soils. Experimental DT50 values were benchmarked against European Food Safety Authority (EFSA) reference datasets using reference value, reference interval, and expected variability derived from laboratory degradation studies. The interpretation was subsequently validated against a larger literature-derived reference dataset. The majority of experimentally determined DT50 values were consistent with the EFSA reference dataset. However, benchmarking against the expected variability identified several exceedances that could not be explained by differences in soil physicochemical properties alone. Validation against the literature-derived reference dataset refined the interpretation of several benchmark exceedances by accounting for a broader range of laboratory degradation behavior, while persistent exceedances identified across reference datasets were highlighted as candidates for further mechanistic investigation. Overall, the proposed benchmarking framework complements existing regulatory degradation endpoints by incorporating expected laboratory variability into the interpretation of newly generated degradation data. The framework provides an efficient first screening step for complex degradation scenarios, enabling researchers to distinguish expected experimental variation from observations requiring targeted mechanistic investigation.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149165687","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 the present study, the total or resin (DOWEX M4195)-extractable Cr(VI) criteria in soil are established by integrating the spiked toxicity dataset with 12 plant species, derived transformation models, and the species sensitivity distribution (SSD) approach. It was found that the total or resin-extractable EC50, which is the concentration that causes a 50% growth inhibition, is well correlated with soil pH and organic matter (OM). Therefore, the developed toxicity prediction models for barley and bok choy can decrease the intraspecific coefficients of variation (CV) for 80% of the studied plant species for both total EC50 and resin-extractable EC50, demonstrating the validity of the cross-species extrapolation approach. Consequently, the total or resin-extractable EC10 values of the other 10 non-model plants can be obtained and then used to construct SSD curves under different soil scenarios.

We evaluated the occurrence, spatial distribution, and ecological implications of pharmaceutical active compounds (PhACs) in soils from the summit of Roraima-tepui, a high-elevation \"sky island\" in the Guiana Shield subjected to unregulated tourism and lacking sanitation infrastructure. Surface soils from anthropogenically influenced and naturogenic zones were analysed for 98 pharmaceuticals using HPLC-MS/MS, and potential risks were evaluated using environmental risk quotient (RQenv), cumulative and mixture-based approaches, and antimicrobial-resistance-specific thresholds (RQAMR). Eleven pharmaceuticals were detected, including antibiotics, antifungals, analgesics, and psychoactive compounds. Compounds associated with direct human use (e.g., ciprofloxacin, clarithromycin, acetaminophen) were primarily confined to anthropogenic areas, whereas others (notably fleroxacin, thiabendazole, pregabalin, and sulfadimethoxine) occurred more widely, including in naturogenic zones. These patterns suggest that heterogeneous inputs, compound-specific behaviour, intense rainfall, and shallow sandstone soils may interact to redistribute contaminants beyond their initial points of introduction. Ciprofloxacin reached concentrations up to 186 ng g⁻¹ and contributed substantially to cumulative environmental risk estimates. Several compounds exceeded predicted no-effect concentrations, and screening-level cumulative RQenv values indicated elevated potential environmental risk. Antimicrobial resistance assessment suggested pronounced selection potential for ciprofloxacin in tourist-impacted areas, although resistance genes or resistant bacteria were not directly measured.
