Abstract

By increasing the world-wide population, the consumption of beverages has grown significantly. Beverages usually contain different heavy metals such as lead (Pb) and arsenic (As), which are toxic for humans and the environment. In our work, atomic absorption spectroscopy (AAS) method was used for quantification of Arsenic (As) and lead (Pb) contents in various beverages. Samples (59) were collected from Isfahan market at eight groups based on their tastes. All groups were contained Pb below the allowable range (50 ng/ml) and also7 out of 8 groups were contained As more than permitted level (10 ng/ml). According to our results, it is important to control frequently heavy metal contamination in beverages due to the usage by a wide range of people.
