Not that this should be any great surprise, but maybe now that scientists are able to measure the adverse effects of combustion-engine vehicle pollution, legislators will take action. One can dream, anyway. From the Wall Street Journal:
Congested cities are fast becoming test tubes for scientists studying the impact of traffic fumes on the brain.
As roadways choke on traffic, researchers suspect that the tailpipe exhaust from cars and trucks—especially tiny carbon particles already implicated in heart disease, cancer and respiratory ailments—may also injure brain cells and synapses key to learning and memory.
New public-health studies and laboratory experiments suggest that, at every stage of life, traffic fumes exact a measurable toll on mental capacity, intelligence and emotional stability…
