The water footprint measures freshwater use for activities, taking into account water consumption and pollution contamination by classifying consumed water into groundwater and surface water (blue water), rainwater (green water), and polluted water (grey water). This study aims to identify a comprehensive water footprint inventory analysis for a denim washing organization and assess the grey water footprint (GWF) based on the effluent concentration of pollution indicators (chemical oxygen demand (COD), suspended solids (SS), ammonium nitrogen (NH4-N), and phenol) measured monthly in 2021. The company used well water for its operations, which constituted 61.79% of the total water use of the facility, water used by the organization by reverse osmosis accounted for 37.60% of total water consumption, and rainwater made up 0.61% of the volume of water used overall. The grey water footprints of COD, SS, NH4-N, and phenol were calculated as 59981.53 m3, 31747.21 m3, 10514 m3, and 48190 m3, respectively. The results illustrated that the COD, which accounted for 40% of the pollutants, had the highest grey water footprint in the organization, corresponding to the amount of freshwater required to assimilate pollutants to meet water quality standards. In addition, the effect of the reverse osmosis system on the blue water footprint of this organization was analyzed by considering two different scenarios. Reverse osmosis considerably impacted the blue water footprint, accounting for over 37% of this organization's water use. It suggests that a wastewater treatment plant using reverse osmosis is an ideal option for recovering water. The main contributions of this study are comprehensively assessing the water footprint components of the denim washing company and understanding sector-specific water footprint at the organization level.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023259","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}

Coagulation process shows the treatment efficiency in terms of turbidity and suspended solids removal. However, despite all these good results, coagulant selection is not an easy task because a coagulant can effectively remove suspended solids but at the same time increase conductivity or coagulants can significantly increase chemical sludge production. The final selection of coagulants depends on the importance attributed to the parameter desired to be removed. In this study, the use of multi-criteria decision making (MCDM) is proposed to help select organic coagulants and hybrid coagulants, which have emerged as an alternative to inorganic coagulants in recent years due to the disadvantages of chemical coagulants and whose use and variety are increasing. Therefore, starting from the parameters determined by the coagulation process results, these techniques will allow weighting these parameters according to the judgments of drinking water treatment plant professionals and determining priorities among coagulants. The agreement between the obtained results and the literature shows that the AHP method is a useful tool for selecting coagulants. According to the results of the AHP matrix created with 4 criteria and 9 alternatives, it has been observed that hybrid coagulants with similar performances to inorganic coagulants have not yet been adopted by drinking water treatment professionals. This may have been due to the higher price of hybrid coagulants and the fact that they are not yet widely used in the drinking water industry.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004822","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}

At the same time, gold mining still has a bad reputation in public opinion due to the environmental and socio-economic challenges it poses. It is therefore important to integrate Mali's gold mining sector into a framework of social responsibility, using the Social Life Cycle Assessment (S-LCA) approach to identify and understand social opportunities and challenges. This study focuses on an application of the S-LCA approach to assess the social performance of industrial gold mining in Mali. Primary data were collected from company representative, workers and local communities. The results of the study show that in 85.2% of ratings, the company has at least good performance and poor performance in 14.8% of ratings. The results show also that the excessive working hours, corruption, sexual harassment and discrimination are identified as social hotspots in the gold mine in Mali. This paper provides a useful literature on the application of S-LCA and for political and administrative decision-makers in the sector to promote fact-driven policies for socially profitable gold mining. Further research would be useful to address the hotspots identified, particularly with regard to the effective management of labor and the prevention of corruption and sexual harassment.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004845","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}

However, pesticides have also been associated with negative impacts to nontarget organisms, including pollinators. Here, we combined pesticide usage and toxicity data to create a toxicity index, which shows that pesticide hazard to honeybees (Apis mellifera) has changed substantially in U.S. maize (Zea mays) and soybean (Glycine max) production between 1998 and 2020. To reduce potential risks to honeybees and increase the eco-efficiency of crop production, efforts should be made to refine management strategies for pests that contribute most to the honeybee toxicity index. In maize, Coleoptera and Lepidoptera pests drive pesticide usage most responsible for hazard to honeybees, although the relative hazard from targeting those pests has decreased over time. In soybean, hemipteran pests were the largest relative contributor to insecticide honeybee hazard. Specific pests that contributed to honeybee toxicity hazard included corn rootworm species (Diabrotica spp.), silk-eating insects, and cutworms in maize, and stink bugs (family Pentatomidae) and aphid species (Family Aphididae) in soybean. We combined crop yield data with the toxicity index to quantify the eco-efficiency, a measure of crop yield per unit of toxicity hazard. While crop yield for both maize and soybean increased steadily throughout the study period, eco-efficiency decreased in both crops between 2012 and 2020, suggesting increases in crop yield have failed to keep pace with increases in insecticide hazard to honeybees.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482899","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}

Increasing soybean production is beneficial to agricultural economies, but significant concerns have been raised about its environmental impacts. This study evaluates the environmental footprint of soybean production using life cycle assessment (LCA) within the \"cradle-to-gate\" system in Madhya Pradesh (central India) for the first time. The analysis demonstrated that untreated residue on the ground increases the global warming potential by 19.78 kg CO2 eq ha-1 and land use emissions by 3.61 m2a crop eq ha-1. Additionally, burning residue significantly increases global warming potential by 210.80 kg CO2 eq. ha-1. Furthermore, the potential for aquatic eutrophication ranges between 0.38 and 0.80 kg N eq. and between 0.16 and 0.21 kg P eq ha-1 for marine and freshwater systems, respectively. This assessment reinforces that global warming potential, fossil resource scarcity, acidification, and land use emissions are the primary environmental concerns linked to soybean cultivation. These issues predominantly arise from fuel combustion in agricultural machinery and the application of soil nutrients throughout the production process. This investigation provides a basis for informed decision-making and the development of sustainable practices to balance the agricultural significance of soybean with environmental considerations.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143122866","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}

Understanding the dynamics and interactions between birds and drilled fields is crucial for developing sustainable farming practices that balance agricultural food production with wildlife conservation. This study focused on the attractivity of freshly drilled onion and carrot fields to birds and the potential exposure of birds to the pesticide-treated onion and carrot seeds available on the soil surface after drilling in Minas Gerais, Brazil. Bird surveys were conducted using scan sampling and point count methods to assess diversity and behavior before, on the day of drilling, and after drilling. Carrot fields showed a decrease in observed species and individuals on the day of drilling, with an increase in bird sightings after drilling. Similar trends were observed in onion fields, with the species composition changing after drilling and a significant decrease in abundance on the day of drilling. None of the species found foraging in the field after drilling were granivorous or omnivorous. Seed exposure was assessed by counting available seeds on the soil surface at different time points after drilling. Seed exposure was higher in the field border than in the field center. These findings indicate that carrot and onion fields offer limited food sources for granivore bird species probably due to low seed availability and intensive seedbed preparation. The research also suggests that freshly drilled carrot and onion crops are unattractive to foraging birds, with low seed exposure and a reduced likelihood of contact with pesticides applied as a seed treatment.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414083","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}

Notable advancements include the integration of nanotechnology, which has enhanced adsorption efficiency and selectivity for specific metals, and genetic engineering approaches that optimize bacterial strains for higher adsorption capacity. Furthermore, these developments have transformed traditional remediation strategies by providing cost-effective, sustainable, and scalable solutions for industries such as textiles, mining, and energy production. This study underscores the practical relevance of bacterial biosorption in wastewater treatment, achieving removal efficiencies exceeding 99% in some cases, as demonstrated by Aspergillus versicolor and Shewanella oneidensis MR-1.

A literature review focused on identifying published approaches assessing the population relevance of adverse effects from EDCs was performed, and, subsequently, 47 primary research papers were evaluated. By extracting from these sources, a novel approach was developed with guiding principles for assessing adverse effects of EDCs at the population level considering (i) choice of focal species, scenarios (and models), (ii) the individual level apical endpoints to be considered, (iii) the magnitude of effect to be imposed, (iv) for what duration effects should be imposed, (v) whether individuals repairing the damage from exposure should be included, (vi) the population-level endpoints to be considered, and (vii) what threshold to set for defining an adverse effect at this level. Recommendations for modeling and field and monitoring studies are included. Case studies are also presented to demonstrate how the proposed approach might be implemented. Although some aspects (e.g., choice of focal species, model/experimental scenario, monitoring study assessment) require further consideration, this should not prevent the use of this approach in a regulatory EDC assessment context. As such, we propose that the approach be used immediately to implement population modeling and perform field studies within this regulatory context. We envisage that consistent application of these principles will encourage regulatory developments in this critical area to provide a much needed level of clarity in the EDC assessment for all stakeholders.","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189128","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}
