Aggressive properties of humic waters have negative effect for metals and building materials (mortar and concrete), which cause not only acidity but also their ability to form complexes, in case of mortar and concrete to the aggressive leaching, which tends to increase the solubility of CaCO3 and CaO. Important precursors of organohalogen compounds in water are mainly fulvic acids and humic acids.	cache/fens-291.pdf	txt/fens-291.txt
