Effects of Engineered Nanomaterials on Plants Growth: An Overview

الملخص EN

Rapid development and wide applications of nanotechnology brought about a significant increment on the number of engineered nanomaterials (ENs) inevitably entering our living system.

Plants comprise of a very important living component of the terrestrial ecosystem.

Studies on the influence of engineered nanomaterials (carbon and metal/metal oxides based) on plant growth indicated that in the excess content, engineered nanomaterials influences seed germination.

It assessed the shoot-to-root ratio and the growth of the seedlings.

From the toxicological studies to date, certain types of engineered nanomaterials can be toxic once they are not bound to a substrate or if they are freely circulating in living systems.

It is assumed that the different types of engineered nanomaterials affect the different routes, behavior, and the capability of the plants.

Furthermore, different, or even opposing conclusions, have been drawn from most studies on the interactions between engineered nanomaterials with plants.

Therefore, this paper comprehensively reviews the studies on the different types of engineered nanomaterials and their interactions with different plant species, including the phytotoxicity, uptakes, and translocation of engineered nanomaterials by the plant at the whole plant and cellular level.
