Preliminary investigations on the influence of clinoptilolite sorbent on white mice in conditions of ecotoxicological experiment

Zeolites from Bulgarian deposits with clinoptilolite mineral matter above 75 % were used as a food supplements in forages for BALB/C mice. Conventional forage mixed with 12.5% clinoptilolite was offered to the animals. To investigate the eventual toxic effect of clinoptilolite sorbent from Bulgarian deposits, ecotoxicological experiment was providing. First results about changes in body weight and LD 50 are present. The obtained results show that the clinoptilolite sorbent is practically non-toxic.
