    Abstract

    In recent years, it has been shown that fine particle concentrations in the atmosphere are strongly correlated with increased mortality rates and respiratory disease. One of the major anthropogenic sources of fine particles is coal-fired power generation. This study has been initiated to determine the contribution of coal fired power stations (CFPS) to the levels of atmospheric dust. Sampling has been conducted in the Upper Hunter Valley, Australia, at an existing monitoring site 7km SE of two large CFPS. Time resolved samples have been collected on carbon tape using a Burkard spore sampler. SO₂ at the site has been shown to be predominantly from the CFPS. This has been used as an indicator of when power station impacts are likely to be greatest; sections of the tape have been selectively analysed by Scanning Electron Microscopy to estimate the mass concentration of particles emitted by CFPS. This paper reviews the methodology and presents preliminary results indicating that the maximum contribution due to CFPS is two orders of magnitude less than annual PM₁₀ measured at the site.
