Analysis and assessment of trace elements pollution in sediments of Lake Uluabat, Turkey.

During the period 2008-2009, eight sampling stations were carried out on Lake Uluabat to assess trace element distribution in the lake sediments and to identify major sources of the sediment pollution. Ten elements, including Iron (Fe), Manganese (Mn), Zinc (Zn), Chromium (Cr), Nickel (Ni), Copper (Cu), Lead (Pb), Cadmium (Cd), Arsenic (As), Boron (B) were determined in the sampled lake sediments. The lowest and highest variation intervals (5.

Fraction distribution and risk assessment of heavy metals and trace elements in sediments of Lake Uluabat.

To examine the status and risk of heavy metal pollution, the distribution of As, Cd, Cr, Ni, and Pb in the sediment of Lake Uluabat was characterized. The present study used a four-stage method to assess the ecotoxicological effects of the heavy metal and trace elements fractions in the sediment of Lake Uluabat. Total Cr and Ni concentrations in the sediment were determined to have exceeded the severe effect level (SEL) limit values.
