The WHO states that most health-damaging particles are those with a diameter of 10 microns or less. This is due to ability of smaller particles to travel deeper into the lungs and pass into blood stream. Sources of PM 10 particles, or coarse particles, can be dirt and dust stirred up on roads by vehicles, or crushing and grinding operations. Mould, dust and pollen are examples of the particles which are between 2.5 an 10 micrometers in size, or about 25 to 100 times thinner than a human hair. With so much suffering, from so much air pollution, in so many other cities in India, what sense does it make to even consider that Australia should supply them with even more coal, to support delusions with big centralised power stations and massive poles and wires?
