The results of the non-carcinogenic risk assessment indicated that the single elements of Mn, Co, S and Cr gave rise to potential health risks with values higher than 0.1 for the three groups. The combination of all the elemental risks in Jinan for these three groups was higher than 1; furthermore, the risk for children be- tween the ages of 6 and 12 years were largest suggesting that the children in Jinan, were faced with more serious potential non- carcinogenic health risks.
