Ecological Systems and Devices Annotation << Back INFLUENCE OF ELECTROMAGNETIC RADIATION ON THE SENSITIVITY OF FRESHWATER CRUSTACEAN DAPHNIA MAGNA, STRAUS TO CADMIUM SULFATE G.K. Papoyan, O.F. Filenko, V.I. Yusupov, K.V. Zotov The infl uence of low-intensity electromagnetic radiation (EMR) of the radio frequency range on the toxicity of cadmium sulfate in concentrations of 0,0054 mg Ca++/l, 0,0162 mg Ca++/l and 0,054 mg Ca++/l for freshwater crustacean Daphnia magna was studied. As a result, a signifi cant increase in the sensitivity of daphnia’s survival and fertility of to the effect of the toxicant after their irradiation with EMR at a frequency of 30 MHz has been established. The appearance of morphological disturbances in the progeny of crustaceans, which reduced the survival rate of crustaceans, was noted. The proportion of individuals with anomalies reached 38 % of the total offsprings after EMR treatment at toxicant concentration of 0,054 mg Ca++/l. The noted effects and regularities can be of signifi cant in conditions of real ecosystems, where aquatic organisms can be exposed to pollutants against the background of widespread low intensity electromagnetic fields. Keywords: Daphnia magna; electromagnetic radiation; radio frequency range; cadmium sulfate; toxicity; fertility; morphological anomalies.
