Název v původním jazyce

Enhancement of toxicity of various POPs in consequence of interaction with dissolved humic substances

Popis výsledku v původním jazyce

Humic substances (HS) are ubiquitous natural products of decomposition of dead organic matter. In soil ecology, HS can be divided generally into three groups: humic acids, fulvic acids and humins (insoluble fraction). In the soil environment, HS are present at concentrations up to 10% (dry weight), and up to 200 mg L-1 in pore water. Biological effects of HS can be both of indirect and direct nature. Indirect effects such toxicants and/or nutrient control via interaction with various HS structures havebeen known for a long time. However, also direct physiological effects such as changes of heat shock proteins expression and biotransformation enzymes activity, or hormone-like effects in animals, have been shown recently. In our previous in vitro study,we described the interaction of 12 HS samples with aryl hydrocarbon receptor (AhR).
