Abstract
This study involved the investigation of heavy metal contents of 100 refined and an equal numberof bakery refined table salt samples collected from the local markets of Lahore, Faisalabad and Gujranwala,Pakistan. Levels of lead, copper, cadmium and iron were estimated using an atomic absorption spectro-photometer. The results indicated a mean ± SD in µg/g levels in the refined table salt samples for lead(0.85±0.22), copper (1.37±0.25), cadmium (0.41±32) and iron (7.72±2.1). For bakery refined table saltsvalues for same metals ranged 1.61±0.51, 2.07±1.2, 0.71±0.21 and 12.6±5.1, respectively. Obtained resultswere compared with the maximum limits recommendations for human consumption set by CodexAlimentarius Commission.
