Mj. Melgar et al., HEAVY-METALS (CD, PB, FE, MN, ZN, CU) IN DRINKING-WATER AS TOXICOLOGICAL INDICATORS, Journal of environmental science and health. Part A: Environmental science and engineering, 32(3), 1997, pp. 687-697
Heavy metals (Cu, Zn, Pbl Cd, Fe, Mn) have been studied in spring wate
rs in order to assess any toxicological problem. The analysis were rea
lized by Atomic Absorption Spectroscopy. The results showed that the w
ater was not dangerous for human health, so the metals considerated as
toxics (Cd, Pb) did not present problems of contamination. The other
metals had values below the maximum admisible concentration, except Mn
, which presented concentrations above the maximum admisible concentra
tion in six spring waters.
