Substance formed during processing of liquid steel or during production of iron castings. Consists primarily of fused silicates and trace elements as oxides as well as trace of alloying elements.
No special studies on sediment toxicity to benthic organisms are available but several observations suggest that slags do not negatively influence the sediment quality and that slags are excellent substrate for growth of benthos.
In a field study it
has been shown that benthic organisms growing on slags (BOS) exhibited
even greater species diversity and population density than on natural
rock. So no negative influence of slags
on benthic organisms could be detected. Therefore
= 100 g/kg was taken as a default value for calculations.
