摘要
The present invention relates to a method for treating lakes with selenium with the intention of lowering the mercury content of fish, and is characterized by supplying to the lake selenium in the form of a selenium salt incorporated in a carrier material capable of dispensing selenium to the surrounding water substantially continuously and in a controlled manner. The carrier material is preferably a rubber-based or silicon-based and biologically degradable material. There is preferably maintained an effective selenium level of beneath 10 mu g.
