Brunnsvatten och grönsaker från sura respektive basiska områden – vilka skillnader i mineralinnehåll föreligger? / Well waters and vegetables from acid areas and an alkaline region –what differences are there in mineral content?
Well waters and women’s hair from acid, and an alkaline area, were analysed on about 40 elements and ions in 1997. The alkaline waters and hair had significantly higher concentrations of e.g. Ca, Mo and Se.
In april 2006, 30 women from the acid area, northern Scania, southern Småland and southern Älvsborg counties, and 30 from the alkaline, the Kristianstad flatland, cultivated carrot, parsley, chive and lettuce. The concentrations of about 35 elements and ions were determined by predominantly ICP OES and ICP-MS. In addition, soil samples from all cultivators were analyzed.
Only Mo concentrations were significantly higher in all the different vegetables from the alkaline district, while Ba, Br, Mn, Rb and Zn levels were higher from acid. In soils from the alkaline area, the pH-levels and exchangeable Ca were higher than in acid soils, while exchangeable Fe, Mn and Na concentrations were lower. There were no strong correlations between soil elements and vegetable elements, except for soil Mn and carrot/lettuce Mn.
The differences in water and hair mineral levels between the two areas in the study from 1997, was not mirrored in vegetables cultivated in 2006. This indicated that the minerals in drinking water were more important in the human uptake, than locally grown vegetables.
