Humic acids interactions with biological

Identification, isolation, and removal of (polyhydroxy)benzenes from the environment have received increased attention throughout the 1980s and 1990s. The biochemical activity of the benzenepolyols is at least in part based on thek oxidation—reduction potential. Many biochemical studies of these compounds have been made, eg, of enzymic glycoside formation, enzymic hydroxylation and oxidation, biological interactions with biochemically important compounds such as the catecholamines, and humic acid formation. The range of biochemical function of these compounds and thek derivatives is not yet fully understood. 

Finally, the concentration of dissolved organic matter and amount of humic acids are required in order to take into account the interaction of free metallic ions with the dissolved organic matter, especially humic substances. This part of the model has not been fully validated for natural conditions (high diversity and complexity of natural organic matter). Furthermore, dissolved organic matter may interact directly with biological material. 

Nucleic acids, proteins and humic acids are among the natural hosts we have employed in the surface functionalization of metal NPs. Since these molecules are the natural targets of many pollutants including PAHs (in fact their biological hazardous effect is due to their ability to interact with them) we have used them as host linkers in order to reach a twofold objective the pollutant detection and the study of the interaction with these important natural targets (7),...
