BIOECOLOGICAL EVALUATION OF THE ARTIFICIAL POND MODEL UNDER EXPERIMENTAL METALS CONTAMINATION IN THE NANOFORM [№ 5 ' 2017]
In the course of production, nanoparticles inevitably enter the environment, including water, which leads to a change in the quality of water and poses a danger to aquatic organisms. In this case, it is expedient to study the evaluation of the effect of metal nanoparticles on aquatic hydrobionts on survival indices, identifying potential risks that arise when nanoparticles of these metals enter aquatic biocenoses. In this paper we made bioecological evaluation of artificial pond model under experimental contamination with nanoparticles such as Fe, Fe3O4, Ni, NiO, using Lemna minor L., Limnea stagnalis, Danio rerio as model organisms. There were revealed specific adaptation features of organisms with different levels of organization to the presence of corresponding nanoparticles in the habitat with limits assessment of their tolerance. During the organisms survival test under conditions of modelled aquabiocenosis, a number of methods were chosen to increase toxicity from nanoparticles to iron oxide nanoparticles regardless of the concentration and the Ni→NiO→Fe→ Fe3O4 exposure period. It is shown that nanoparticles of iron and its oxide in all investigated concentrations, represent a great danger for hydrobionts in the conditions of artificially created aquabiocenoses, than Ni and NiO nanoparticles, due to greatest toxicity.
