So, don’t design your suspension with excessive toe and stop drifting and doing burnouts. Those two things will go a ways to reduce this. Real solution is to reduce the amount of rubber on the road entirely (less cars and trucks), but we can at least lower the effect with better alignments and driving discipline.

Article says more natural rubber tires with fewer modifier chemicals (this means all season and winter tires will be usless in winter), better drainage designs by roads to filter out contaminants (article mentions as well only 2% of contaminants reach the ocean), and better driving skills will help.
