The antibacterial properties of silver are not always beneficial – getting into the ground, nanoparticles of this substance can kill beneficial microorganisms and affect food safety. Scientists at the Southern Federal University (SFedU) investigated the effect of silver nanoparticles on the soil and determined the rate of their concentration in black soil. According to experts, such indicators have not yet been developed anywhere in the world. The results are published in the journal Plants.
Silver nanoparticles have antibacterial properties, so they are used in many industries, for example, in food, textile and medical. However, due to these properties, they can cause a poisonous effect when they fall into the ground. This can occur as a result of the production, use or disposal of goods. The negative impact of silver nanoparticles on the soil has not been practically studied, the scientists said.
