Assessment of Lead Accumulation by Different Plant Species Grown Around the Former Battery Production Factory Berat of Albania, using Atomic Absorption Spectrometry Mirela Alushllari, Nikolla Civici Centre of Applied Nuclear Physics, Faculty of Natural Sciences, University of Tirana, Albania [email protected] Abstract Lead is a trace element in the earth's crust. It is known to be toxic at low concentrations. Both natural and anthropogenic contributions are the sources of lead emissions to the environment. Lead is easily accumulated in the edible parts of leafy vegetables, as compared to grain or fruit crops. The accumulation of lead in agricultural soils is potentially hazardous to human, livestock and plants species. The aim of this study is: determination of lead in different spontaneous plant species grown around the former Battery Production Factory as well as calculation of determinate bioaccumulation factors (BAF) soil to plant. Three sampling points were chosen and we have collected a total 9 samples, where 6 samples are spontaneous plant species and 3 were surface soil samples, in the area of factory in Berat, Albania. Samples were analyzed for their content of lead by using Atomic Absorption Spectrometry (AAS) in the Centre of Applied Nuclear Physics, Faculty of Natural Sciences, University of Tirana, Albania. From results obtained, concentrations of biological samples were found very high (152-383 mg/kg). The concentration ranges of lead in biological samples collected at different points are compared with the Maximum Contaminant Levels (MCL) specified by the Directive No. 1881/2006, Brussels. Concentrations of lead were measured also in surface soil, near the root of plant species, in one of the most polluted areas in Albania, Uznove, Berat. The concentration in representative surface soil samples is about 4-19 times higher than level of lead recommenced by European Union according the Directive 86/278/EEC. Also we have calculated bio accumulation factor (BAF) soil to plant. Key words: Lead, biological samples, BAF, Atomic Absorption Spectrometry.
