1. Environmental and health hazards of chemicals in plastic polymers and products
Sammanfattning : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. LÄS MER
2. Phthalates in landfill leachates : a signature of their degradation: Analytical aspects & toxicological considerations
Sammanfattning : Phthalic acid diesters comprise a large group of organic compounds that are used to manufacture a variety of products all over the world, and this has raised concerns about the fate of these compounds in the environment. The diester-containing products often end up in landfills, where they are degraded by various micro-organisms, which gives rise to transient intermediates such as phthalic acid monoesters and ortho-phthalic acid.

3. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris
Sammanfattning : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. LÄS MER
4. Modern landfill leachates – quality and treatment
Sammanfattning : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. LÄS MER
5. Microbial Treatment of Heavy Metal Leachates
Sammanfattning : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. LÄS MER
