A recent study shows that large piles of coal produce measurable quantities of fine particulate air pollution within a 25-mile radius. Covering coal trains and storage piles could reduce the problem.
As the latest controversy about tunnel exhaust stacks and respiratory health plays out in the media, some community members are proposing solutions that just don’t make sense.
Australia needs stronger policy aimed at curbing air pollution, but the options currently on the table fall short. For now, we could all aim to drive less and turn off the engine when the car is idle.

Tiny particles of a mineral known as magnetite may be causing havoc with our health.
