Determination of Some Trace Metals in Canned and Fresh Beans from Basrah Markets- Iraq

Abstract

In present study, three heavy metals (Lead, mercury and copper) in (60) canned Beans samples were determined by atomic absorption spectrophotometer. The trace metal contents, expressed in ppm (mg/ kg), varied from (1.07-1.22 mg\kg) dry weight in fresh samples and from (1.09-1.42 mg\kg) in canned samples for Copper (Cu) and from(1.22 - 1.67 mg\kg) in fresh samples and from ( 1.41 - 2.181 mg\kg ) in canned samples for a Lead, and from (0.05 - 0.19 mg\kg) in fresh samples and from ( 0.07 - 0.55 mg\kg) in canned samples for Mercury. The results of this study showed the concentration of mercury in summer samples exceed normal levels, and statistical analysis of results by ANOVA showed significant seasonal variation between samples. The study showed that summer season had the highest recorded concentrations of trace elements in canned Beans samples.
