Combined Action of Oil Products and Humate on Daphnia
D. I. STOM, A.V. DAGUROV
Abstract
The joint influence of commercial preparation of humic substances and oils, oil-products and their individual components on Daphnia magna was studied. The presence of humic substances prevented, or at least reduced the transition of Daphnia magna into the superficial film in emulsions of oil products. It is shown that in some concentrations the preparation of humic substances weakens toxic effect of emulsions of oil-products and their saturated solutions on Daphnia.
