Results and discussion

Any other information on results incl. tables

The viability of the cells exposed to the test substances for ca. 5 hours was very slightly (no statistics performed) elevated compared to control. A prolonged incubation period of 20 hours resulted in increasing toxicity, however clearly lower compared to the positive control (standard quartz).
