I'd be interested to see it, that's not an obvious conclusion to me. The health difference of an EV is a percentage increase in tire particles but a complete absence of tailpipe emissions. I would not expect tire particles to be the more significant factor, especially when the impacts of microplastics are so unknown.

Tailpipe emissions are a significant problem (https://iopscience.iop.org/article/10.1088/1748-9326/ab35fc), and I know this is an extreme example but you can literally kill yourself by just leaving a car running in an enclosed space. EV tailpipe emissions are not fully replaced by electricity generation emissions, even if you get your power from 100% coal (and you don't). Power plants are much more efficient than internal combustion engines.
