FIELD: biology. ^ SUBSTANCE: invention is designated for biotesting water and aqueous extract samples. Daphnia are immersed firstly in solution or water for culturing to be tested and then daphnia are transferred into lightproof chamber with outlet hole for culturing and this chamber is immersed into water. Time passing out daphnia from the testing chamber to light is measured and toxicity of analyzed solution is estimated by difference time in daphnia passing out. Method allows carrying out the rapid control of water and aqueous extracts toxicity in laboratory and field conditions. ^ EFFECT: improved method for biotesting. |
