Szukana fraza: [Abstract = Four of them were selected for biotoxicological tests\: three belong\-ing to the class of Aspergillus and one belonging to the class of Cladosporium \(Table 1\). The method of the bioindicating test applying Dugesia tigrina Girard \(Plathelminthes, Turbellaria, Tricladida\; Paludicola\) was used to determine the toxicity of the selected moulds. All biotests gave a positive result. It means that moulds synthesise toxins that increase the danger for the inhabitants of the infected buildings \(both toxicological and allergic danger\).]
