evaluation of metal composition of cast iron disc used in local grinding machine

The need to prevent metal-related sickness is the driving force for this research. the research evaluates the composition and concentration of metals present in cast iron grinding disc used for local grinding. different acidic mixtures were used to digest the pulverized cast-iron disc, and atomic absorption spectrophotometric analysis revealed the presence of essential minerals such as iron, copper, zinc, manganese, and toxic metals like metals cadmium, chromium, lead, and nickel. the concentration of the metals varies in different ranges cadmium 0.73 to 3.44, chromium 0.88 to 6.80, lead 0.55 to 1.58, nickel 0.40 to 7.17, manganese 3.12 to 21.00, zinc 2.03 to 40.50, iron 1.93 to 49.16 and copper 3.00 to 26.92 all in mg/kg. the presence of heavy metals in the grinding disc could be a source of food contamination and possible potential health risks.
