limestone, exploited near bielawy, a town located in the kujawsko-pomorskie province ofpoland, is the main raw material in the production process in a cement plant. the dust emitted by the factory is of alkaline ph and contains such heavy metals as: cadmium (cd), lead (pb), chromium (cr) and nickel (ni). the research aims at assessing the influence of cement dust on the total content and bioava...

in the recent years, agricultural soils have received more chemicals in various forms for higher yields. this may result in the accumulation of metals in soils which subsequently may be transferred into the agricultural crops. in the present investigation, nickel content of 58 composite soil samples and also agricultural crops, is studied. ni in samples of soil and agricultural products were ex...

the increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. using treated wastewater in agricultural irrigation can provide more adequate supply of high quality water for human consumption, but their heavy metal applications effect must be regulated to ensure no physiological problems for both the plant and ...

At the end of December 1993 and also at the end of January 1995, the river Meuse, one of the major rivers in Europe, flooded and river banks were inundated. We investigated the possible health risks of exposure to heavy metal concentrations in river bank soils resulting from the flooding of the river Meuse at the end of 1993. Soil and deposit samples and corresponding aerable and fodder crops w...

The SGVs and the additional advice found here should be used only in conjunction with the introductory guide to the series entitled Using Soil Guideline Values (Environment Agency, 2009a), the framework documents Updated technical background to the CLEA model (Environment Agency, 2009b) and Human health toxicological assessment of contaminants in soil (Environment Agency, 2009c), and Contaminan...

although the application of biodegradative genetically engineered micro organisms (gems) for bioremediation is very promising, the risks of their release should be assessed before their introduction into the environment. lux-marked ralstonia eutropha h850lr (formerly alcaligenes eutrophus h850lr) was introduced into sterile and non-sterile soil microcosms at matric potentials ?2.11, ?30, ?750, ...
