Which Contaminants of Ceiling Voids Might come Mainly from Coal Gas Emissions?
It would seem a reasonable hypothesis that for those elements for which the concentration in the flue dust is greater than the concentration in the ceiling cavity in general, that the flue pipe was probably a major contributor of that element to the dust in the cavity. To test this, a researcher would as a minimum, need to determine whether the particular element could have originated in the flue pipe but then escaped from the ceiling void due to being in a fine particulate or gaseous form etc. isotopic fingerprint research methods could be used on those elements with different isotopes which originate in different ore bodies, for example, lead. Such research as carried out by Prof Brian Gulson, a CSIRO researcher in Sydney, has in the past been used to determine for instance whether the lead in a person’s blood stream mainly came from petrol or from ore dust in Broken Hill. So the elements which are higher in the flue dust than in the cavity dust and therefore may have come mainly fro
