[Atmos_enviro_health] Dioxine emissions from wood fires

[Tord Kjellstrom]

Hi all,
 
A recent study by Neil Pearce, Massey Univ, NZ, of workers in the 2,4,5-T plant in New Plymouth, NZ, showed an increase of cancer, which may be due to dioxin exposure by inhalation.  I am sure both food and air play a role in health related exposrue.
 
Regards
 
Tord

	Dear Constance,
	                that was probably my presentation. 
	I would suggest that you have a look at the NDP Technical Report no 12: Human Health Risk Assessment of Dioxins in Australia (2004) from DEH.  In section 3.7 (P121) there are a couple of summary tables (T3-32 and T3-33) of expected exposure for Australians in general, and children, that show the importance of different exposure pathways.  Of course there is still a remaining issue of just what are the actual sources that are responsible for the dioxin in our food.
	
	Cheers
	John

	Hi All,
	
	I recently attended a seminar on dioxins at which it was stated that there
	was a rise in dioxin levels in the ambient air in winter due to wood fire
	(open fire places and wood heaters) use. However, there were some views that
	the rise in dioxin levels in the ambient air did not present a health risk
	to the population as it was only ingestion of dioxins that was a problem.
	Any views on this?
	
	Regards,
	
	Constance Dewan.
