Impact of NP TiO<sub>2</sub> on the bivalve <em>Mytilus trossulus</em> (Gould, 1850) was studied using the DNA comet method, and the levels of DNA damage were assessed. Shown that 10-day exposure to NP TiO<sub>2</sub> at concentrations of 200 and 1000 μg·l<sup>-1</sup> leads to destructive changes in the DNA of the gills and of the digestive gland of the mollusks. Difference between DNA damage in two examined tissues was noted. Furthermore, the elevation of titanium content and malondialdehyde content in digestive gland of mollusks was noted.</p> ER -
