Test methods for water treatment equipment
(1) Test substance.
The test substance shall be dissolved or suspended in a suitable medium. It is recommended to choose water first, followed by vegetable oil (such as corn oil), and consider using other media (such as carboxymethyl cellulose, gelatin, starch, etc.). For non-aqueous solution medium, its toxicological characteristics should be understood. Whether its toxicity should be determined before the test. The maximum volume of liquid for each oral exposure depends on the size of experimental animals. The liquid dose to rodents is generally 1 ~ 2ml / 100g. The oral dose of each dose group was the same by adjusting the concentration of the test solution.
(2) Laboratory animals and feeding environment.
Choose healthy adult mice or rats, or other sensitive animals The weight of the small piece is 18 ~ 22G, and the rat ~220go animal should be made in the environment of the experimental animal room for at least 3 days before the test The number of heads, the temperature and relative of the animal room meet the national standards for metrological certification of animal room.
