This initial site visit led to a the storage of military materials and hazardous request from the Ministry of Defence (MoD) of the substances at the Astana site. Government of the Islamic Republic of Afghanistan to further assess the potential environmental It provides a description of the site conditions, a and health risks associated with the storage of summary and rationale for the fieldwork that was hazardous substances at Astana. The MoD also carried out, factual records, and an interpretation sought assistance from UNEP in dealing with any of the laboratory analyses. This document also sets unacceptable risks to the environment and human out a series of recommendations to mitigate the health. This report documents the assessment of identified environmental and health risks linked to those risks. the ongoing use of the site for grazing livestock. This project, which was managed by UNEP representatives based in Kabul and overseen by the UNEP Post-Conflict Branch in Geneva, comprised: • the investigation and characterization of hazardous substances stored on the subject site; • the assessment of potential environmental and health risks associated with the storage of hazardous wastes, and the communication of these risks to the relevant stakeholders; and • the development of pragmatic recommendations for remedial action. The project also included capacity-building for representatives from the Afghan National Environmental Protection Agency (NEPA) on the assessment of potentially contaminated land and standard procedures used to sample soil and water.

The main purpose of this study was to assess the influence of long term solid waste disposal on water and soil physicochemical properties. Soil and water samples were collected in and around the solid waste disposal area. The samples were analyzed for physicochemical characteristics and potentially toxic elements using ICPMS. The results revealed that some water parameters analysed well below WHO and EU standards for drinking water. Therefore, the surface and ground water samples in this study are good for drinking purposes. However, the application of water quality index (WQI) suggests that the ground and surface water around the open dumpsite are marked as good and poor water in quality respectively. High concentration of Ca in all soil samples is expected because the regional geology is calcareous. The concentrations of PTEs were found in order of Mn> Fe> Ni> Zn> Cr> Cu> Pb> Se> Cd.

Shvetsova and Jang Hee Lee * School of Industrial Management, Korea University of Technology and Education, 1600, Chungjeol-ro, Byeongcheon-myeon, Dongnam-gu, Cheonan-si, Chungcheongnam-do, Cheonan City 31253, Korea; [email protected] * Correspondence: [email protected] Received: 4 April 2020; Accepted: 14 May 2020; Published: 18 May 2020 Abstract: This research deals with the theoretical and practical issues of investment support activities for industrial waste management in developed countries, based on the example of South Korea. The main goal of this research is the evaluation of waste treatment investment projects and understanding their impact on the development of environmental policies. The problems of forming the sustainable systems for controlling the disposal of industrial wastes are being studied. The authors discuss the practical application of environmental policies and modern technologies of South Korean companies in the field of industrial waste processing. The approaches of waste investment project’s evaluation are applied and multi-criteria decision making (MCDM) methods were discussed for various cases and applications. Using MCDM methods, the authors study the effectiveness of investment projects in waste treatment activities in Korea. The analyses of MCDM methods are implemented in this research to provide some instructions on how to effectively apply these methods in waste treatment investment project analyses. Furthermore, the authors propose a combination of multi-criterial selection and interval preferences to evaluate waste treatment projects. The proposed approach improves the method of calculating economic efficiency based on a one-dimensional criterion and sensitivity analysis.
