ECOTOXICITY AND BIODEGRADATION OF GLUE ON THE BASE OF ISOCYANATE

Popis výsledku v původním jazyce

In the area of adhesive intended for load-bearing wooden elements, the priority is currently to use adhesive with the lowest possible impact on the environment, which at the same time do not contain formaldehyde. One option is to use polyurethane glue. However, adhesives are generally materials for which ecotoxicity or biodegradation has been practically very poorly studied, and their environmental assessment is usually based only on theoretical calculations of the toxicity of the individual substances in the adhesive. The aim of this work was therefore to test the ecotoxicity/biodegradation of the selected glue after its hardening (Lignofix D4, STACHEMA CZ) on green algae (Desmodesmus subspicatus) and yeasts (Saccharomyces cerevisae). Toxicity was evaluated in aquatic tests on the prepared leachate from the glue and the water containing the tested glue. The results indicated any toxicity of eluates for yeasts and algae but toxicity of solution containing own glue for algae (31%). Biodegradaton and biocolonisation of hardened isocyanate glue is so probably possible by microorganisms according to the results of the present study.
