Testing of Binders Toxicological Effects

[摘要] The article presents the results of a study of the toxicological effect of binders with different compositions on the vital activity of plant and animal test-objects. The analysis of the effect on plant cultures was made on the basis of the phytotesting data. The study of the effect of binders on objects of animal origin was carried out using the method of short-term testing. Based on the data obtained, binders are ranked according to the degree of increase in the toxic effect: Gypsum → Portland cement → Slag Portland cement. Regardless of the test-object type, the influence of binders is due to the release of various elements (calcium ions or heavy metals) into the solution. In case of plant cultures, the saturation of the solution with elements has a positive effect (there is no inhibitory effect), and in case of animal specimens - an increase in the toxic effect.
