Embodiment 1
[0031] The screening of embodiment 1 optimal embryo culture medium
[0032] 1.1 The preparation of different formulas of embryo culture medium and the effect of culturing zebrafish
[0033] A Prepare embryo culture solution containing the following concentrations of inorganic salts with ordinary water, adjust the pH to 7.2, culture zebrafish embryos for 72 hours, and observe the transparency and survival rate of zebrafish. The specific results are shown in Table 1:
[0034] Table 1 Effects of embryo culture medium prepared with ordinary water on zebrafish embryos
[0035]
[0036]
[0037] B Use weakly alkaline water with a pH of 7.2 prepared by electrolysis of pure water to prepare an embryo culture solution containing the following concentrations of inorganic salts, culture zebrafish embryos for 72 hours, and observe the transparency and survival rate of zebrafish. The specific results are shown in Table 2:

Embodiment 2
[0041] Example 2 Zebrafish Toxicity Assay
[0042] The above-mentioned embryo culture fluids of numbers A1 and B1 were used to prepare organic solutions with graded concentrations, and the solutions were subjected to the zebrafish toxicity test, wherein each treatment was repeated 5 times, and the average value was taken, and the control was the embryo culture fluid without solvent A1 and B1. The determination is mainly carried out through the following steps:
[0043] 1) The cultivation of zebrafish:
[0044] The male and female common zebrafish of the sexually mature AB line were separated into separate tanks, and were raised in a circulating water culture system, with 14 hours of lighting and 10 hours of darkness alternately, the water temperature was kept at 28°C, and brine shrimp artificially incubated for 24 hours were regularly fed;
[0045] 2) Embryo selection:
[0046] The day before egg collection, sexually mature zebrafish were placed in a mating tank at a ratio ...
