Heavy metal contamination of agricultural soils and subsequent accumulation of these metals in plants is a growing interest. In this work heavy metal and selected micronutrient content (Cd, B, Al, Co,...
EFFECT OF HEAVY METALS ON SELF-PURIFICATION PROCESSES IN RIVERS
self-purification biochemical oxygen demand heavy metals toxicity
2010/3/26
The inhibitory effects of heavy metals on self-purification processes in surface water were
studied. Toxicities of the metals were evaluated on the grounds of the results of the Biochemical Oxygen De...
Prediction of extractable metals (Cd, Pb, Fe Cu, Mn and Zn) in sewage
Sewage sludge heavy metals sequential extraction bioavailability
2010/9/14
The study shows that the metal ion binding to the biotic surface such as sewage is pH dependent and that there is an optimum pH for bioavailability of metals. The influence of the sludge pH and organi...
