چکیده
The multi- walled carbon nanotubes (MWCNTs) are one of the most widely used engineered nanoparticles and are expected to enter natural ecosystems. More studies on plants, as a part of food chain, are needed to understand profoundly the toxicity and health risks of CNMs as ecotoxicological stressors. In this study, The effects of multi- walled carbon nanotubes (MWCNTs) with a length 30 nm on seed germination and growth of six plant species () were evaluated in petri dish (direct exposure) and in soil in a greenhouse experiment (soil exposure). Data demonstrate that under both culture conditions, low or mild concentrations MWCNT either stimulated or had no effect on seed germination, root growth and…
