| Description
| - Soil organic matter is important in controlling heavy metal behaviour in soils. This study aims to determine the distribution of organically bound Cd, Pb, and Zn between humic and fulvic acids in 20 samples of heavily polluted Fluvisols. Traditional procedure of alkaline sodium hydroxide/pyrophosphate extraction ofhumic substances with consequent humic acids precipitation by acidification was used. All of the three metals were bound predominantly of fulvic acids (mean share was 98.4,82.0,and 95.7 % oftotal organically bound Cd, Pb, and Zn content, respectively). Mainly the level of pollution controlled the amount of metals bound on fulvic acids. On humic acids, a limited amount of specific sorption sites for the metals is expected. Lead content bound on humic acids was negatively correlated with soil pH. The results suggest relatively high potential mobility of organic fractions of heavy metals in sols under this study. The selectivity of alkaline extracting agent is briefly discussed.
