Estimating human health risks associated with heavy metal exposure from bottled water using Monte Carlo simulation.

Water is the most important non-organic compound for living cells, and the life of all living organisms depends on it. Water is not found purely in nature, but it always contains some solutes, suspended matters and soluble gases. In this study, 11 bottled water brands (500 mL) were sampled across the Kashan city market to determine the concentration of selected heavy metals (Cr, Cd, Pb, Ni and As) and evaluated their potential risks following consumption. The concentration range of Cr, Cd, Pb, Ni and As were 5-34 µg/L, 1.5-7 µg/L, 1-7 µg/L, 2-29 µg/L,
