文摘

The formation mechanism of heavy metal fluxes migrating with the solid runoff of rivers and composing more than 90 wt % of the metals involved in the system of water migration was studied. The aggregation features of the finely dispersed soil components and the important role of humic acids in the formation of microaggregates were revealed. The particle-size compositions of the readily mobilizable microaggregates and river suspensions were determined and compared. On the basis of the comparative geographical study of the fractional composition of the humic acids from different soil types and the calculation of the metal weights in microaggregates, the effect of the HA1-to-HA3 fraction ratio on the structure of the metal fluxes was shown.
