Deposition of heavy elements on Belgian agricultural soils.
1980
Navarre J.L. | Ronneau C. | Priest P.
A network of 19 rain gauges was set up over Belgium in agricultural zones. Determination of heavy metals content of water samples collected during a 1 yr meteorological cycle allowed to estimate wet plus dry deposition rate of many toxic metals over the country. It appears that soils contamination by deposition exceeds contamination through the use of chemical fertilizers.
