Natural organic matter and ionic strength (CaCl₂) affect transport, retention and remobilization of silica encapsulated DNA colloids (DNAcol) in saturated sand columns

In the terrestrial environment, interactions between natural organic matter (NOM) and colloids can lead to the formation of an environmental corona around colloids, influencing their transport behaviour and, ultimately, their ecotoxicity. We used a synthetically designed colloid tagged with DNA (DNAcol) as a surrogate for natural colloids and...

The influence of de-icing salts on the remobilization of heavy metals in an artificial wetland

Artificial wetlands are used at different locations in the world as a treatment facility for wastewater of different composition. In order of Rijkswaterstaat several artificial wetlands are constructed for road runoff treatment. In all cases the artificial wetland is preceded by a sedimentation basin / storage buffer. One of them is located...
