Calcium and Strontium in Swedish Waters and Fish, and Accumulation of Strontium-90

摘要

The purpose of this study has been to investigate the correlation between calcium and strontium in fish in relation to the concentration of these elements in the water. An investigation of the uptake of strontium-90 has also been made and a permissible level of strontium-90 in the water is calculated based upon the uptake in fish muscle tissues. Lakes with calcium concentrations between 2-63 mg/l have been studied and samples from the Baltic coastal water are also included.nThree fish species are studied, viz. Pike (ESOC locus (L.)), perch (Perca fluviatile (L.)) and roach (Leuciscus rutilus (L.)). Bones, muscle tissues and skin + scales have been analyzed.
