effect of magnetized water treatment on someecological aspects of freshwater ostracodacyclocypria kinkaidia dobbin 1941

ABSTRACT

The present study was conducted to determine the effects of magnetized water treatment with in different intensities 500, 1000 and 1500 Gauss on some ecological aspects one' species of freshwater Ostracoda Cyclocypria kinkaidia Dobbin 1941, which important species in faun of aquatic habitats of Iraq. This species are considered a component of the food chain.The obtained results compared with these species which lived in the river [control]. These samples of Ostracodean animals were collected from Al - Habebia lake in Baghdad province by using the test sieve with mashed sized about 75um and zooplankton net with opening diameter about 25 cm and mesh sized 335 um.These species were exposed to three different intensities 500,1000 and 1500 Gauss magnetized water treatment under laboratory conditions, the resulting effects were compared with those obtained from a control experiment where the individuals kept in normal untreated water.Result of these experiments showed the indicated variation in the some physical and chemical characteristics of water.The present study showed non significant change in pH values, electrical conductivity and total dissolved solids in the magnetized water. But increased these values was increased with increased intensity of magnetized water treated with 1500 Gauss intensity for Ostracodean animals where restrict this study.Dissolved oxygen concentration was signifi cantly increased intensity of magnetized water especially in treated water with 1500 Gauss intensity for Ostracodean animals comparated with untreated water. Nonsignificantly change in water temperature values with increased intensity of magnetized water comparrison with untreated water where those Ostracodean animals lived
