EFFECTS OF SUB CHRONIC EXPOSURE TO EMF-RF ON SPERM PARAMETERS OF TILAPIA (OREOCHROMIS MOSSAMBICUS)S.S. Dikwalkar and S.M. GuptaAbstract Technological advancement in the communication industry has led to the production of modern devices capable of producing radiations. These radiations whether ionizing or non-ionizing have resulted in the formation of electro smog all over the world. The increase in electro smog in the environment is showing many negative effects like decrease in the sperm count, lipid peri-oxidation damage in sperm cell, reduction in seminiferous tubule and testicular weight, DNA damage, leukemia, low sperm count etc. in different organisms, still many technological advances are been established which may show a significant unwanted effect in the biology of organisms. This study aims at studying the sub chronic exposure of Tilapia (Oreochromis mossambicus) to EMF-RF having frequency of 2.3 GHz. Three groups were acclimatized to lab conditions. 45 numbers of fishes used for the study, 15 fishes were distributed in each group viz. control, group I with 1 hour/day exposure and group II with 2 hour/day exposure. Fishes were exposed to EMFRF as per the experimental design. After the exposure some sperm parameters like milt volume, sperm count, sperm motility and duration were studied. The values from milt samples were tested statistically using descriptive statistics and single factor ANOVA. Sub chronic exposure of fishes to EMF-RF did show a significant change in the sperm parameters undertaken for the study. More similar studies are required to evaluate the harmful effects if any from the upcoming technologies. |
