Invited by Zhang Xiwang, the associate professor of Monash University, Han Zhihua, Ji Guixiang went to Australia to participate the technology seminar for the toxicity assessment and bioassay of sediment between July. 13, 2015 to July 17, 2015. The seminar topics include the method for determination of initial toxicity of sediment, pretreatment method of sediment, identification program for the sediment toxicity, and et al. During the visit, we exchanged the views of toxicity identification procedures with the experts from the Monash University, and discussed the feasibility of the scheme of constructing water sediment toxicity identification program TIE in China. In addition, we also discussed the advantages and disadvantages of the midges, corbicula fluminea benthos as the initial toxicity determination. The use of activated carbon, resin and zeolite in the treatment of water sediment was also discussed. We also visited the Environmental Engineering Laboratory of Monash University during the visit. I hope to get the advanced experience of the toxicity assessment from Australia, and strengthen cooperation with Australia. We also hope to build a long-term cooperation mechanism through this technology seminar.

Monash University is one of the largest National Universities in Australia; it is also the founding member of the Australian Group of Eight. The Group of Eight (Go8) is the coalition of leading universities in teaching and scientific research in Australia. The environmental technology research group is charged by associate professor Zhang Xiwang. The main research directions include the preparation of inorganic and organic inorganic composite membranes, forward osmosis, Reverse osmosis (RO) membrane process, 2D, 1D nano catalyst, adsorbent, waste water energy recycling and resource and advanced oxidation technology.
