Description
In this article the influence of four nanometal oxides on tadpoles of lake frog in pure water and in low concentrations of sawage of sugar factory is considered. It is revealed the protecting action of three nanometals, characterized by an increase in growth rates and decrease in death rate of tadpoles in sawage of sugar factories
