Sequential Extraction as a Method for Analysis of Heavy Metals Mobility in Soils
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Polluted soil with metals could affect human health through direct contact with soil, but potentially greater threats could rise, for example, from infiltration of the metals into groundwater aquifers or by the plant uptake of those. The hazard in soil attributable to metals is often assessed by determination of their total content or pseudo-total content in soil.

„Brownfield Sites – New Energies“: Feasibility Studies Concerning the Construction of Solar Power Systems on Former Disposal Sites
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2012)
Bavarian politics defined a heavy increase of renewal energies until the year 2021 in their concept about innovative energies. Solar power systems inhibit an important role within this concept. Thus, solar power systems shall produce about 16 % of the Bavarian energy production until 2021. The construction of solar power systems on former contaminated land sites and disposal sites shall be supported through special measures. Therefore, the support programme „brownfield sites – new energies" has been created. In a first step a number of potential sites shall be identified. Different projects have been defined on this behalf by the Bavarian State Ministry of the Environment and Public Health (StMUG), where the GAB is in charge of the project management.

Investigations of Site-Contaminations in China: Initial Site-Contamination-Investigation and -Remediation in China
© Deutscher Fachverlag (DFV) (6/2010)
Currently in China there is proceeding a serious intensification of the environmental law relating to future critical limit values and the obligation of accompanying measures. Also in China the assessment of possible financial relevant features of sites like hazardous waste contaminations and groundwater pollution is becoming more important. Nowerdays, the investigation concerning contaminations of sites in China is becoming necessary and interesting for German investors. Meanwhile, in the course of all-embracing Due-Diligence-examinations for site assessments in China for a German investor the R&H Umwelt GmbH from Nuremberg/Germany (R&H) already has performed several initial site-contamination-investigations including the initial investigation of the building-substance on industrial sites.

Hard work for the microbes: Soil remediation in a tank farm
© Deutscher Fachverlag (DFV) (6/2010)
In a tank farm in Belém (Brazil) the soil was found to be highly contaminated. With the help of a biological process this soil is remediated by microbes and then reused at the site. Because the process was originally developed in Germany, it had to be adapted to suit the local climate. The entire operating crew are subject to the tank farm's technical safety regulations, which comply with international standards and are strictly implemented.

Hydrodechlorination of PCBs-contaminated soils and groundwaters

As in most South American countries, the magnitude of the Chilean contaminated site problem is yet to be established. To date, only two studies have been conducted for the identification and preliminary risk assessment of sites under suspicion of contamination, considering the associated human health and environmental risks. The latter work is a case study in an industrial Region in South Central Chile, the second most important in social and economic terms.

Field deployment of persulfate-based electrokinetic in-situ remediation

In Austria, 40,438 old industrial sites have been localized (2006), whereas organic pollutants account for 93 % of the contaminated sites and more than 40 % thereof are affected by mineral oil and phenol. Furthermore, there are about 6,000 gas stations in Austria declared as contaminated land (Spausta & Weihs 2006). Up to now, no adequate In-situ remediation method has been developed which can cope with this scale of the problem.

SETTING-UP OF A RISK BASED REMEDIATION GOAL AT A MERCURYCONTAMINATED SITE IN INDIA
© IWWG International Waste Working Group (10/2007)
A mercury in glass thermometer factory was operative in Southern India during 1984 to 2001. The manufacturing process for thermometer making include stem cutting of imported glass, followed by end opening, end cutting, bulb forming, mercury filling, top chambering, scale setting, grading, top sealing, screen printing and certification. The manufacturing area had 36 exhaust fans to facilitate air change and maintain the workplace occupational safety standards for air 0.05 mg/Nm3 of mercury. The expelled air containing mercury vapours from the manufacturing area settled down on the surrounding soils and trees close to the manufacturing area causing contamination soil and biomass adjacent to the manufacturing area.

LEACHING BEHAVIOUR OF PAH’S IN DEMOLITION WASTE AND CONTAMINATED SOIL Premium
© IWWG International Waste Working Group (10/2007)
The investigation of pollutant transfer from waste or soil with leachate into groundwater is of fundamental importance for the assessment of risk potential posed by abandoned waste deposits or other contaminated sites. Following the German Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV, 1999), a leachate forecast is required for the soil-groundwater pathway. The estimation of the pollutant transfer can be performed, among other methods, on the basis of source term strength of contaminated materials determination by laboratory tests.

REMEDIATION OPTIONS APPLICABLE TO A Cr(VI) CONTAMINATED SITE IN MEXICO
© IWWG International Waste Working Group (10/2007)
Hexavalent chromium is a critical pollutant commonly released into the environment as a result of its applications in numerous industrial processes, such as the production of stainless steel, in plating, tanning of leather and the production of metallic pigments, among others. The harmful toxic effects of Cr(VI) on humans, animals, plants and microorganisms is well known. Human health disorders include organ damage, dermatitis and respiratory impairment, as well as the proliferation of respiratory cancer (Proctor et al., 2002; Langard, 1990). Cr(VI) has an elevated mobility in the environment due to its high solubility in water in a wide pH range that may cause environmental problems when not adequately managed.
