- Abstract
- The effect of compounds Etafosf, Amidofosf Anifosf and in the concentration range 1×10-5- 1×10-19 mg/l hydro-biological test objects, Daphnia magna and Scenedesmus quadricauda. Found that the chemical compound bioeffect Etafosf appears diametrically opposite way, depending on its content in the low- and ultra low concentrations. Namely, as the dilution of 10-5 mg/liter to 10-14 mg/l and toxicity manifested alternation stimulating action of the same formulation with respect to the test object being studied. Ctimuliruyuschy effect Amidofosfa and Anifosfa detected at a concentration of 10-12 mg/l, but it was lower than Etafosfa.
