1 Scope

This standard specifies the chemical Zhuan class acute immobilisation test principles, instruments and equipment, test preparation, test procedures, quality assurance And quality control, data and reports. This standard applies to test and evaluate possible exposure to chemicals aquatic ecological environment of acute inhibition of Zhuan class activities.

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 Caused a 50% inhibition of the test subjects Zhuan activity concentration. 2.2 Qing Huang test vessel, the body can not swim in the 15s Zhuan, as activity was inhibited.

3 test substance information

a) structural formula; b) purity; c) solubility in water; d) vapor pressure; e) chemical stability in water and light in; f) octanol - water partition coefficient (Pow); g) reliable quantitative analytical methods, recoveries and detection limits in aqueous solution; h) biodegradability test results. Principle 4 Young Zhuan (beginning of the test Zhuan age less than 24h) in a certain range of concentrations of exposure to the test substance solution 48h, with respect to the blank Group, 24h and 48h were recorded on the test substance Zhuan type of activity inhibition. Based on the results of analysis and calculation of the 48h EC50. Also Available 24h EC50 of results.

5 reference substances

Recommend using potassium dichromate (K2Cr2O7), which 24hEC50 range of 0.6mg/L ~ 2.1mg/L, see reference [1], [5].

6 instruments and equipment

6.1 test vessel exposed to the test solution and other equipment is the best all-glass products made from or other chemically inert material. Tolerance test Usually as a test tube or beaker, must be cleaned before each use in accordance with standard laboratory procedures and clean; capped test vessel should be easy to reduce Water evaporation losses, and to prevent dust from entering the solution. Volatile substances should be large enough to completely closed container, so as not dissolved Solutions of oxygen-limited or too low. ......
