Abstract

The flux of atmospheric/soil CO2 consumed by chemical weathering of the continents (FCO2) can be estimated from bicarbonate concentrations in surface water. Using data from the bibliography for 232 small monolithologic watersheds, relationships between FCO2 and the runoff (Q) have been determined For the major rock types outcropping on the continents. The models fitted to these relationships are then applied to the Garonne and Congo river basins, in order to calculate the mean CO2 flux consumed in these basins. The results obtained are close to previous estimates bosed on field measurements
