A Perkin-Elmer Model A Analyst 700 (Norwalk, CT, USA) flame atomic absorption spectrophotometer was used for metals analysis. The hollow cathode lamp of Cd and Pb were run under the conditions suggested by the manufacturer. Overall analysis was carried out with an air/acetylene flame, using 10 cm long slot-burner head and without any background correction. The 100 μl of the samples was injected through self-made injection system of Teflon funnel and Eppendorf Pipette.
