The Impact

Sediments deposited in sewer pipes have been concerned as one of the main pollution loads from combined sewer overflow (CSO). Since the toxicity, mobility and bioavailability of heavy metals depend on their speciation, it is necessary to consider not only their amounts but also their speciation to evaluate the adverse effects on aquatic organisms in receiving waters. Sequential extraction method was applied to the size-fractionated sediments to evaluate heavy metal speciation. Although the speciation of Cr, Ni, Cu, Zn and Pb differed among sampling points as well as their contents, the content of easily exchangeable fraction was strongly correlated with total content for all the metals except for Cu. The result of heavy metals speciation revealed that Ni, Zn and Pb in combined sewer sediments could have high mobility potential. The result of size-fractionated sediments indicated that the contents and mobility potential of the heavy metals were larger as particle size was finer. Thus, it is important to control fine sediments in combined sewer to reduce the impact of CSO pollution.

Risk Scale

The risk scale estimation of the agricultural environment pollution by heavy metals using the sequential extraction method From among various industrial contaminants which can pollute agricultural environment, heavy metals having the capacity of bioaccumulation deserve special attention. The total composition analysis of the heavy metals content in the polluted soils does not provide enough data about their accessibility to the crops cultivated on these soils. It is very important to have the information about the forms in which the examined element exists, because it decides about its mobility and toxicity for the environment. Using the sequential chemical extraction method of Zeien and Brümmer the fractions of Cu, Pb, Zn, Cd and As in the soils influenced by emissions from the Copper Smelter GŁOGÓW, were investigated. The aim of these investigations was to determine the availability assessment of the mentioned elements to the crops cultivated in this region.
