Enhancement of toxicity of various POPs in consequence of interaction with dissolved humic substances
Original language description
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).
