Abstract

A simple, quick semi-quantitative test for the determination of lead metal in canned fruits,vegetables other than dehydrated onion, fish, and meat products, has been developed using theoptimised concentration of dithizone reagent under alkaline pH as the test solution, which onreaction with the sample solution gives green to blue to violet to red colour, depending on thelead concentration in the sample.  The quick test results were compared with atomic absorptionspectrophotometric analysis. A total of 80 samples were analysed and it was found that the leadcontent ranged from 0.001 ppm to 10.35 ppm in all the samples.
