The team tracked individual plankton them from birth to death and exposed them to various concentrations of sodium chloride (rock salt) and calcium chloride.
No salt bans in my area at least, but it’s only effective above a certain temperature (around -15°C iirc). On sidewalks/bike roads it’s usually gravel+salt and on roads only salt. An unfortunate side-effect of gravel is that it (a) needs to be swept up in the spring which adds cost and (b) poses a hazard to cyclists once the snow is gone.
Many Nordic countries use gravel as a salt alternative. Pretty sure there are salt bans for private areas.
Trams, railways.
Example from Helsinki, little maintenance needed (like heated switches).

It’s usually automatically swept by the rain, and as a cyclist I don’t find gravel hazardous: I slow down before a bend and that’s pretty much it…
