Zeolites are materials used in households, agriculture, medicine, water abatment, oil refining, etc. But there is little information about how they might affect living beings. We will study the effect zeolite nanoparticles have on zebrafish embryos. Zebra fish are model organisms so we will be able to provide data on the safety of zeolites usage in everyday life and industry. The results will contribute to assess the potential impact of zeolites on health.
