 abstract={In order to work out a procedure of diminishing the amount of heavy metals, barium and strontium in wastes, laboratory wastes were collected and investigated. The analysis revealed that mercury and silver are present only in the precipitate, as well as about 213 amount of lead, bismuth and cobalt. Other elements occur mainly in solution. It was also found that there was no justification for the separate segregation of particular analytical groups of elements, especially in the cases where it is difficult to enforce requirement of collecting wastes in proper containers. Solid wastes were divided into two groups: I - containing mercury and 2 - without mercury content. Metals were eliminated in the form of sulphides and hydroxides by their precipitation with sodium sulphide, flocculation, sedimentation and dehydration. Solutions left after metals separation meet requirements for wastes, which can be disposed of the sewage system.},
