BIOACCUMULATION OF ZINC FROM OZONATED TIRE GRANULATE BY TERRESTRIAL ORGANISMS

Popis výsledku v původním jazyce

Waste tires from traffic can be used for many purposes, including insulation materials in building engineering. An interesting possibility seems to be their application as granules. Ozonation can be one of the ways to better break down tires and get granules from them. However, various organic or inorganic substances can be released from them during their production or use. It can lead to a risk for both environment and humans. Zinc belongs to important potential toxic elements. For that reason, the toxicity and bioaccumulation of zinc from ozonated tire granules were studied on earthworms Eisenia fetida (28 days-bioassay) and on mustard plant species Sinapis alba (4 day-bioassay). The results indicated no mortality for earthworms. The toxicity for plants was though observed; it was manifested in the form of root inhibition. Bioaccumulation of zinc was confirmed for both organisms. The measured amounts of zinc were higher in earthworms than in plants. The use of rainwater in the plant test was found to decrease the toxicity and bioaccumulation, as compared with distilled water.
