Abstract
Consumption of bottled mineral water in Brazil has increased over the past year, due to its convenience and relative safety. The quality of water is affected by the structure of the water network, the pipe and the treatment of water that sometimes could change its taste. The mineral and inorganic
contaminants levels of 69 samples of bottled mineral water were investigated by Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES). The
concentrations of mercury, lead, cadmium, copper, iron and phosphorus were below the limit of quantification. 17 % of the domestic sample brands were in accordance with the label and for the imported ones, all the samples agree or were in conformity with the label. 63 % of the domestic mineral water failed to comply with the Brazilian new legislation about bottled mineral water labelling. In conclusion, the analysed samples were proper to consumption.
