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.
There is no indication of any hazard of slag to birds, and it has been shown that slags do not exhibit any relevant effect on aquatic or terrestrial organisms. Consequently, no measurements have been done with birds.In a field study with slags on herring, it was observed coincidently that gulls feed indicriminately on eggs, larvae and adult herrings in control natural rock fields (basalt, granite, and diabase) as well as in slag fields.
No study designed to measure the toxicity of slags on birds was
performed. However, there are some coincidental observations from
another field study suggesting that slags do not negatively affect birds.
study was conducted in the Nord-Ostsee-Channel to elucidate the effects
of stones of slag and natural rock on the reproduction of the herring,
These eggs and the newly hatched fish larvae are indiscriminately eaten
by gulls, and form for some period of the year the feed for large gull
flocks which systematically harvest the eggs and larvae in a water depth
of up to 40 cm.
