Bioconcentration——Flow-through Fish Test
Abstract: In order to control the environmental risks from new chemical substances, preventing environmental pollution, protect human health, protect the ecological environment. Need to manage the new chemical substance, and with China within the territory of China to complete sample test data must include ecological toxicology data of new chemical substance. In laboratory cultures of Gobiocypris rarus for the subjects, for C3H2Cl4 toxicity test of large m. typical aquatic organisms. The determination of potassium dichromate in 28d exposure period of large growth, survival and reproduction of m. the impact of research is exposed to different mass concentration and processing time of potassium dichromate, toxic symptoms, production of large m. and mortality. The results show that the observation record close of m. mortality, m. kind grow 28d no to observe the effect of concentration of , m. kind grow 28d the lowest observable effects of concentration of ; Observation record close of m. production, large breed m. 28d no observation effect concentration is , large breed m. 28d minimum observable effects of concentration of , with the increase of C3H2Cl4 concentration, kiss m. reproductive capacity and body length were depressed, and increased mortality.
