Characteristics of the Acute Biotoxicity and the Toxic Factors of Tributaries of Baiyangdian Lake

This study aimed to combine the acute biotoxicity test with physic-chemical analysis to pinpoint the toxic factors of river surface water. Water samples were collected from six sampling sites along Fu River, the main tributary of Baiyangdian Lake (China), in the spring and summer of 2018. Acute biotoxicity test was carried using luminous bacteria (Vibrio qinghaiensis sp. Q67) and zebrafish (Brachydanio rerio). The results showed that the river water exerted certain toxic effects on zebrafish and luminous bacteria and the latter was more sensitive to the toxicity of river water; the toxicity to luminous bacteria at the 6 sampling sites was higher in summer than in spring. According to the Pearson correlation coefficient analysis, COD, NH3-N, Zn and Cu were the pollution factors that gave rise to the acute toxicity of the surface water and thus should be put under special control.
