The worldwide recycled aluminum generation is increasing quickly thanks to the environmental considerations and continuous growing of use demands. Aluminum dross recycling, as secondary process, has been always considered a problematic issue in world. aim this work propose methodical easy procedure for proposed system selection MCDM problem. Here, an evaluation method, integrated FAHP, presented evaluate waste management systems. Therefore, we drive weights each pair comparison matrix by...

Background/Objectives: Aluminum dross as waste is always a problematic issue. The aim of this study to apply systematic method for the management system selection problem in environment management. Methods/ Statistical Analysis: In study, methodology extended fuzzy TOPSIS and based on LCA applied by using nearest weighted interval approximations. functional unit includes aluminum scrap, which are defined 1000 kg. model confirmed case city Arak. scenarios ranked their closeness coefficient...

The aim of this study is to compare the potential environmental impacts three kinds aluminum: primary aluminum ingot (A), secondary (B) and mix (C) with each other.For purpose, life cycle assessment model developed based on damageoriented approach.For unit process, reference flow 500 kg.The results show that "A" has highest in all categories, "B" intermediate most environmentally friendly process.As a surprising result amount for fluoride, BTEX VOC compared models "C" as air emission.Finally...

In this study, the life cycle assessment model for secondary extruded aluminum represents a cradle-to-gate process that starts with recycling scrap and ends in ultimate product of transferred to final manufacturer.In following, data are mainly collected from literature, ecoinvent3's database.The quantitative analysis use energy pollutants production estimated eco-indicator-99 methodology SimaPro8.0.4 package.The impact on environment is studied by evaluating three damage impacts: human...

<title>Abstract</title> Employees working in various sections of the hospital are inevitably exposed to toxic gases. Chronic exposure these gases increases risk occupational diseases. Therefore, this study aims evaluate impact chemical on pulmonary and blood parameters. This cross-sectional was conducted 2024 a located Tehran with sample size 110 participants. In study, OSHA 103, NIOSH 1501, 101, 7901, 3500 were used determine levels isoflurane, BTEX, formaldehyde, nitric acid, chlorine...

In recent years, many organizations have used management system certification such as the Environmental Management System (EMS). The purpose of present study is to assess effect (ISO14001) on hospital performance. This an applied (regarding study) and descriptive research data are gathered through secondary (library) primary (questionnaires) sources. causal. After confirming validity reliability questionnaire, it was for collection. population includes staff. community considered limited...

Abstract Background It is acknowledged that the landscape composition and configuration of land cover within a watershed could influence environmental ecological quality. Therefore, rivers receive pollution from their surrounding amount intensity this are affected by structure around river or watershed. Methods In research, we estimated relationship between characteristics water quality in two different basins. We used multiple stepwise regression analysis redundancy to explore quantitative...
