Trace elements and heavy metals in mineral and bottled drinking waters on the Iranian market

29 October 2014

A survey of Iranian waters, sampled from 2010 to 2013, is presented. A total of 128 water samples from 42 different brands of bottled mineral and drinking water were collected and analysed for contamination levels of lead (Pb), cadmium (Cd), copper (Cu), arsenic (As) and mercury (Hg).
Determinations were performed using different test methods for the different elements. Arsenic concentration in six bottled gaseous mineral samples was higher than the related limit. Values obtained for analysed heavy metals in all samples were permissible according to the limits of national and international standards (Food Additives & Contaminants: Part B: Surveillance, 6 October 2014).
