Preliminary observations on the metal content in some milk samples from an acid geoenvironment

The metal content of some milk samples was analyzed from areas of acid sulphate soils along the course of the river Kyrönjoki in western Finland. Comparative analyses were made with samples from the Artjärvi-Porlammi area. The variations of analyzed metals AI, Ba, Ca, Cr, Cu, Fe, K, Mg, Mo, Na, Sr and Zn are not great in both areas except that of Al, which is clearly associated with the acid environment in the Kyrönjoki valley. The portions of these elements in milk are relatively high as compared with data from literature. It is obvious that they show environmental contamination. Under acid circumstances the metals in milk may create serious geomedical problems
