Nanoparticles have an increasing accumulation and effect as day to day in aquatic, terrestrial and atmospheric environments, and one of the most basic factors determining these effects is their sizes. As the material size decreases, the distribution and accumulation of particles are facilitated and accelerated. In this study, the possible nanotoxicological effects of nanomagnetite (Fe3O4 NPs), hydroxyapatite (HAp) (synthesized by the recovery of waste eggshells) and Fe3O4-HAp nanocomposite on wheat germination percentage and chlorophyll production were evaluated. It was determined with SEM images that the Fe3O4 nanoparticles was in the size of 22-30 nm, while the Fe3O4-HAp was 90-350 nm. The presence of HAp particles caused a decreasing in the germination percentage compared to presence of only Fe3O4 nanoparticles, as like in the root elongation (20-27 %). The chlorophyll content was determined in the both aged and young leaves on second, third and fourth weeks of wheat plants. Results showed that wheat plants were sensitive in the early stage of plant growth (second week) to the all test chemicals. The presence of HAp in the growth media decreased the chlorophyll content of wheat because of their sizes. The maximum decreasing of chlorophyll content in wheat was observed at the 40 mg L-1 HAp treatment as 86 %. All the test chemicals used in this study uses in many areas, thus it should be detailed evaluated ecotoxicological aspect.
