Quantitative Determination of Heavy Metal in Water and Sediment from Lakes in North Moldova, Romania

The effects of heavy metal pollution of surface waters, and consequently of lakes, have disastrous consequences on the ecosystems, having a long reminisce due to their poor mobility. On health, these toxic metals have different effects, depending on the degree of exposure and the type of pollutant. The purpose of this work was to evaluate according to the presence of heavy metals the water quality in five lakes in the area of Moldova: Lake Ciric II and Lake of the Botanical Garden "Anastasie Fătu" - from the Iasi county, Lake Stânca-Costesti and Guranda Pond from Botosani county and Fălticeni Lake in Suceava county.The study has highlighted the impact of different human activities on water quality. Although it has not been found that water is critically polluted in terms of its content in heavy metals, the situation remains a worrying problem.
