I think a more informative comment would add some perspective on how harmful break dust actually is or isn't. Whether or not someone would use it as seasoning is a moot point.
For example, I wouldn't sprinkle dirt all over my food. But I'm perfectly happy for my food to grow in dirt. Does that mean contact with dirt = bad? No.
- jacquesm 6y agoIt depends. The older the brake the worse the dust. But even modern brake dust is not something you want to ingest if you don't have to. In general dust is the worst possible form that you can get some contaminant in, it offers the largest reactive surface per unit weight and can get into all kinds of places that it shouldn't. As for the dirt: plants act as natural filters, they select that which is good for them using their root systems and use that to build the rest of the plant as they go along. Some plants can be used to extract certain materials from the soil, others do the opposite and will react by rejecting the contaminants. What exactly happens depends on the plant, soil conditions, humidity, amount of sunlight and lots of other factors besides. Not all dirt is good, not all plants grown in all dirt are good, not all dirt is the same.
