Direct and Indirect Detoxification Effects of Humic Substances
نویسندگان
چکیده
The review summarizes studies on the detoxification effects of water-soluble humic substances (HS), which are products natural transformation organic in soils and bottom sediments that serve as detoxifying agents water solutions. HS microorganisms quite complex: neutralize free pollutants (indirect bioeffects) also stimulate protective response organisms (direct bioeffects). Prospects potential problems bioluminescent bacteria-based assay to monitor toxicity solutions presence discussed. main criterion for bioassay application is versatility ease use. efficiency different pollutant was evaluated, mechanisms Particular attention paid direct complex + indirect HS. focuses function radionuclides salts stable metals, with special consideration antioxidant properties

Direct and Indirect Effects
The direct effect of one event on another can be defined and measured by holding constant all intermediate variables between the two. Indirect effects present conceptual and prac tical difficulties (in nonlinear models), be cause they cannot be isolated by holding cer tain variables constant. This paper presents a new way of defining the effect transmit ted through a restricted set of paths...

متن کاملBinding of mercury(II) to aquatic humic substances: influence of pH and source of humic substances.
Conditional distribution coefficients (K(DOM')) for Hg(II) binding to seven dissolved organic matter (DOM) isolates were measured at environmentally relevant ratios of Hg(II) to DOM. The results show that K(DOM') values for different types of samples (humic acids, fulvic acids, hydrophobic acids) isolated from diverse aquatic environments were all within 1 order of magnitude (10(22.5 +/-1.0)-10...
متن کاملHealth Value of Humic Substances
It has been found that humic acid in dose levels of 100-300 milligrams per kilogram body weight has no effect on bleeding time, clotting time, thrombin time, plate count, or induced platelet aggregation (49). Red blood cells and hemoglobin stay on normal levels under the influence of humate in comparison with control groups (15). Literature has indicated that the red blood cells have the capabi...
متن کاملPhysiological effects of humic substances on higher plants
The physiological effects of humic substances (HS) on some aspects of plant growth and metabolism are examined. Evidence has been presented on that the effect of HS on plant growth depends on the source, concentration and molecular weight humic fraction. While a low molecular size (LMS , 3500 Da) fraction easily reaches the plasmalemma of higher plant cells and, in part, is taken up into them, ...
