Abstract
The present study investigates the selected heavy metals and metalloids concentration in different type salts available at local market of Raipur. Contents of Cu, Fe and Pb in the analyzed salt samples were found lower than that of recommended values of Codex Standards and Indian Standards. Copper content ranged from 0.005 – 0.035mg/kg, iron content ranged from 0.323 – 1.520 mg/kg and lead ranged from 0.12 – 0.17mg/kg. Lead content in all the samples was within the codex specification of 2.0ug/g of lead content. Potassium content ranged from 55.86 to 19070.8 mg/kg and sodium ranged from 596.82 - 1127.00 mg/kg. The result shows that rock salt can be considered lowest in potassium and sodium concentration in comparison to the other analyzed salt samples, and therefore it’s an ideal salt to be used by the persons suggested to take low sodium/ potassium in their diet. On the other hand the excessively higher concentration of potassium in other salt samples is a source of worry and interventional measures need to be put in place to ensure that the salt is properly purified and treated.
