[Changes in phototaxical index of Daphnia carinata under electric field of direct current in response to Cr6+ and Hg2+].


In order to detect toxicants sensitively in water by phototaxity of Daphnia, we studied the influence of DC electric field on phototaxity of self-bred Daphnia carinata, a mono-clone with high phototaxity, and the changes of their phototaxity in response to Cr6+ and Hg2+ after the treatment of DC electric field. The result indicated that the treatment of DC… (More)
