Coal mining, transport and burning brings pollution problem to Hunter Valley

The recent studies of air pollution in the Hunter finally show us the constituents of pollution and points to the likely sources. We agree with the editorial comment (Newcastle Herald, April 30) that it is extraordinary that the EPA seems to have leapt to the defence of the coal industry, because a close look at the results shows that coal mining, transport and burning is a major contributor to pollution.

Air pollution is a complex mixture of components. The largest fraction shown from the Particle Characterisation Study in Newcastle was sea salt which is probably innocuous, however this is true wherever air pollution has been studied. The large health studies from Europe and North America showing air pollution to cause lung cancer and heart disease also included a salt fraction, so this is not an argument to ignore the high levels of fine particle pollution recorded here.
