Leachability of arsenic and heavy metals from blasted copper slag and contamination of marine sediment and soil in Ninh Hoa district, south central of Vietnam

2014 | Elsevier

In recent years, shipping activities developed in Ninh Hoa district (south-central Vietnam), have raised an urgent environmental concern related to the use of copper slag as abrasive material for removing rust from the surface of the ships. This study was conducted to investigate the characteristics of the blasted copper slag (BCS). Enrichment Factors (EF) were used to assess the contamination status of sediments and soils in the surroundings of the BCS dump site. The potential release of As and heavy metals (HMs) from BCS was examined through pHstat and cascade leaching tests in combination with XRD analysis. From the results, As, Cr, Ni, Pb and Zn were characterized as moderate severely enriched to severely enriched while Cu showed extremely severe enrichment in the sediments. Regarding the soil collected at the dump site, it was strongly contaminated with As, Cu and Zn (extremely severe enrichment) whereas Cr, Ni and Pb were ranked as severely enriched. This study also demonstrates that it is important to use local background values of As and HMs in soils and sediments for a correct estimation of the degree of As or HM contamination. The cascade leaching test results from the BCS showed that the concentrations of the regulated HMs leached were lower than the EU limit for non-hazardous waste; except for Cu. Results from pHstat leaching tests at pH 4 with BCS indicated that upon acidification, HM release from the <1 mm fraction is higher compared to the bulk sample. A significant release of Cu from BCS was also observed for both fractions (<1 mm fraction and bulk sample) in pHstat leaching tests. In view of the elevated Cu concentrations found in the slag, the potential recovery of Cu from BCS should be investigated.

Reports

Regional Study on Mercy Waste Management in ASEAN Countries

2017 | UNEP

The scoping study serves as a preliminary assessment of the current mercury waste management systems and practices in the ASEAN member states (AMS). It is aimed at identifying the current available sources of the relevant information, summarizing the essential information, and identifying gaps of information, challenges, needs and opportunities for further studies or actions. This study covers all AMS jurisdictions, while sector-wise, it focuses on Mercury in the Artisanal and Small-scale Gold Mining (ASGM); Mercury waste from the chemical manufacturing industry using the Chlor- Alkali process; as well as mercury in fluorescent lamps from industry and household sources. In terms of the Hazardous Waste Management (HWM) aspects under the BC Art. 4 and MC Art. 11, the study covers policies; legislative and regulatory framework; institutional framework; main sources/generators, waste prevention and minimization; handling, separation, collection, packaging and labelling, transportation, storage; treatment and disposal; and contaminated sites.

Cleanup, Storage, and Transport of Mercury Waste from Healthcare Facilities

2010 | UNDP

The UNDP GEF project involves demonstrating best practices for the management of mercury waste and promoting mercury-free devices. As health facilities phase out mercury devices, proper methods of storage and transport are needed. This document is intended for project countries where national norms and guidelines for cleanup, storage, and transport of mercury waste do not exist at this time.

Persistent Organic Pollutants: Contaminated Site Investigation and Management Toolkit

| UNIDO

This toolkit aims to aid developing countries with the identification, classification and prioritization of Persistant Organic Pollutants-contaminated sites, and with the development of suitable technologies for land remediation in accordance with best available techniques and best environmental practices.

Chemicals Management: The why and how of mainstreaming gender

| UNDP

This publication, part of the Gender Mainstreaming Guidelines Series, provides an approach to mainstreaming gender in chemicals management, together with a discussion of priorities for United Nations Development Programme support to assist partners with mainstreaming gender considerations at each step of a national process to develop or strengthen a sound management of chemicals regime.

Integrating Sound Management of Chemicals into MDG-Based Development Planning

2010 | UNDP

This United Nations Development Programme Guide provides a systematic approach to countries to help assess their capacity for sound management of chemicals, identify needs, and ultimately mainstream or incorporate identified priorities into national Millenium Development Goals-based development policies and plans.

Training Resource Pack for hazardous waste management in developing economies

| UNEP,ISWA

This Resource Pack is a set of training materials available as electronic files for individual use and further adaptation. It is inteded to assist in giving conference or lecture presentations of key topics in hazardous waste, as well as providing guidance in the organisation of training workshops of various sorts. The subjects cover the full range of topics in hazardous waste management from prevention to treatment and disposal, as well as regulatory aspects, support services and development of national strategies.

Hazardous Waste Training Resource Pack

1996 | ISWA

The Training Resource Pack manual is composed of a series of chapters on key stages of the hazardous waste management cycle, in particular: context; fundamentals; prevention; regulation; management; treatment.
