Antioxidant in tire dust kills coho salmon

Permeable Cinder block style roadways are a thing, not sure they would work for primary roads though

 

We do add them to food as preservatives, and rubber is a plant product.

Problematic synthetic compounds could be phased out, but research on replacements won't find all the potential problems once they go out into the world. The OT one isn't directly killing the fish, for example, but what in degrades into.

Just more catch basins in the storm drains can help. Adding a basic filtering system with the material in those run off socks around construction sites could neutralize the problem compound in the OP.

 

Interesting chart


But notice this is microplastics. Bottles and what not you see in marine garbage patches are not initially 'micro'. How rapidly they get made smaller is not yet clear.

Tire dust is already small. It's the 1 kg or less that goes away as one gets down to the 'wear bars' and then buys new tire.

Originally cited article says tires are 1 to 3% anti-oxidants. That's actually a lot over a billion tires.

In the 'beetle larvae eat rubber' publication, it is not clear if they started with material containing anti-oxidants. Gotta ring them up.

 

city dust is an interesting one

 

Synthetic textiles are what washing machines erode from clothes, and send down the pipe.

 

I'd say lint is bigger than the micro range.
This is the stuff that went down the drain from the washer, and manages to get past any water treatment before being released into a water way.
