Adsorption of heavy metals on sonicated activated sludge

open access: yesUltrasonics Sonochemistry, 2009
The objective of this work is to assess heavy metals fixation capacity on sonicated activated sludge. Ultrasonic treatment of sludge has lead to its desintegration and changes physico-chemical characteristics such as soluble chemical oxygen demand, proteins or particle size distribution.

Heavy metal distribution in some French forest soils: evidence for atmospheric contamination [PDF]

open access: yes, 2003
This study is one of very few dealing with the distribution and the origin of heavy metals in French soils from a priori non-polluted forest areas. The abundance of heavy metals measured in these soils decreases as follows: Cr) Zn)Pb)Ni)Cu)Co4Cd. Total
