[The influence of electromagnetic radiation of industrial frequency on Daphnia magna (Straus)].
The influence of electromagnetic radiation of industrial frequency on survival, efficiency, physiological parameters of Daphnia magna (Straus) was investigated. The electromagnetic field with intensity of a magnetic component 15 microTl and an electrical one 12 kV/m was generated. The researches were carried out in acute and chronic experiments. The experimental group was exposed to electromagnetic radiation for 8 hours daily for 30 days. As a result of the study it was revealed that the influence of electromagnetic radiation with the given parameters did not have the lethal effect on the test objects. It was found that electromagnetic radiation negatively affected Daphnia fertility. On the average, a real fertility of the Daphnia in the experimental unit was 26.32% compared to the control. The age of puberty in the experiment increased twice in comparison with the control.
