Soil contamination from heavy metals and persistent organic pollutants (PAH, PCB and HCB) in the coastal area of Vasternorrland, Sweden
This paper presents an experimental study on the leaching of heavy metals, toxic chemicals and persistent organic pollutants (POPS) - PAH, PCB and HCB - from soil dredged from the coastal area of Vasternorrland in northern Sweden. The soil was stabilized with cement/slag. Samples were subjected to m...

Samples were tested to evaluate the min/max contents of pollutants (mu g/l) for heavy metals (As, Ba, Pb, Cd, Co, Cu, Cr, Hg, Mn, Mo, Ni, S, V, Zn) and the hydrocarbon fraction index in the excess water. The leaching of heavy metals and POPs was assessed in sediments after the addition of the binder. The comparison was made against the two mixes (cement/slag in 30/70% and high/low binder with low/high water ratio). The results showed that 70% slag decreases the leaching of heavy metals and POPs. The equilibrium concentrations of DOC and heavy metals at L/S 10 (gg/l) were measured during the shake experiments to compare their levels in the groundwater that was used as a leachate. The leached content was assessed at L/S 10 in the upscaling experiments using four samples for PAH, PCB and various fractions of hydrocarbons: C 10-C40, C10-C12, C12-C16 and C35-C40. The shake test showed a decrease in the leaching of heavy metals and POP substances from the soil subjected to stabilization by a higher amount of slag added as a binder. A binder blend with 30% cement and 70% of GGBFS showed the best performance. Article in Journal/Newspaper Northern Sweden Flanders Marine Institute (VLIZ): Open Marine Archive (OMA) |
