PCT No. PCT/HU90/00020 Sec. 371 Date Dec. 20, 1990 Sec. 102(e) Date Dec. 20, 1990 PCT Filed Mar. 21, 1990 PCT Pub. No. WO90/11143 PCT Pub. Date Oct. 4, 1990.The invention relates to an environment-protective agent consisting of silicon-containing minerals for adsorbing radiactive metal isotopes and toxic heavy metals, which comprises as silicon-containing minerals with a particle size of 0.001 to 0.5 mm; a natural diatomaceous earth and at least two natural zeolite minerals of the general formula MxO.Al2O3.YSiO2.7H2O wherein M stands for sodium, potassium or calcium; x is a number between 1 and 2 inclusive of both extreme values; Y is 3 or 10; and Z is 6 or 7 treated by dilute acid, washed to neutral, dried to a constant weight at a temperature up to 115 DEG 0 C. and then heat-treated at 150 DEG to 350 DEG C., preferably at 250 DEG C., where the amount of each mineral ingredient independently of each other is at least 0.1% by weight up to 99.8% by weight calculated to the total weight of the agent. The invention further relates to pharmaceutical compositions and animal foods containing the above agent according to the invention as active ingredient.
