Our study also involved the analyses of Cd, Pb, and Cr. Chromium is one of the crucial minerals which enables proper functioning of insulin (Morris, Kouta, Robinson, MacNeil, & Heller, 2000). It
also participates in maintaining the configuration of RNAmolecules (Eastmond, MacGregor, & Slesinki, 2008). Cd and Pb
are known to be toxic to humans and may affect the functionings
of several organs.
