Heavy trace metal and macronutrient levels in various soft drinks and juices

The levels of selected heavy toxic trace metals (Cr, Ni, As, Fe, MR Cd, Cu, Hg, Pb, and Zn) and macro-nutrients (Na, K, Mg and Ca), along with relevan t pH and TDS (total dissolved solids) measurements on local/imported carbon ated waters, juices mineral spring and natural waters are reported. The ato mic absorption technique was applied for these estimations conducted on thi rty four samples procured from local markets. The study revealed that nutri tional quality of local carbonated waters was better than that of fruit jui ces, both in terms Of heavy toxic true metals and macro-nutrient levels. Th e local Pepsi cola sample contained maximum mercury (0.535 mg/L) while Tops showed maximum arsenic (0.837 mg/L). Out of cardioard packed juices. apple juice was found to have maximum arsenic (2.920 mg/L). Local fruit juices w ere found not to conform with the standards allowed for safe ingestion of m icro- and mure-metals in various drinks, as laid down by WHO.
