Immobilising of Cd, Pb, and Zn contaminated arable soils close to a former Pb/Zn smelter: a field study in Austria over 5 years.

29 Sep 2009 Numerous smelter sites are surrounded by rural land. The entrance of non-essential metals such as lead or cadmium into the food chain is very likely as well as phytotoxicity effects of zinc. Finding a realistic solution for these large-scale ... Read more...


Bioassays for evaluating the water-extractable genotoxic and toxic potential of soils polluted by metal smelters.

29 Sep 2009 Physicochemical analyses of polluted soils are limited in their ability to determine all hazardous compounds, their bioavailability, and their combined effects on living organisms. Bioassays, on the other hand, can evaluate environmental quality ... Read more...


Subchronic lead feeding study in male rats and micropigs.

29 Sep 2009 This study compared the lead uptake from contaminated test soil of known lead concentration with a soluble lead acetate standard, which was considered to be 100% bioavailable. This study also compared the lead bioavailability from this ... Read more...
