|Description = Intake fraction (iF) means the fraction of an emission that is finally inhaled or ingested by a target population. There are several studies about estimates of iF for primary fine particles. These are often in the order of one in a million; values are higher for traffic than for other sources. Tainio and coworkers have estimated iFs for Finnish emissions derived from different source categories, including energy production plants. | |||
Fine particles travel in the atmosphere for several days or weeks, and several hundred or thousand kilometres from the source. Therefore, most of the exposure occurs far from the source, unless the exposure very near (less than 100 m) is very intensive. In the case of a MSWI with a high stack, the exposure very near the source is negligible. This is especially true for secondary particles that only form in the atmosphere during several hours or days. | |||

|Description = Intake fraction (iF) means the fraction of an emission that is finally inhaled or ingested by a target population. The exposure to dioxins occur after a multistep process. First, dioxins are emitted into the atmosphere often due to a combustion process. Dioxins are persistent molecules and can transfer hundreds or thousands of kilometres before depositing to water, vegetation, or soil. It absorbs tightly onto surfaces, and therefore it is rather inert if adsorbed to soil. However, when dioxins deposit to water, they enter the aquatic food chain and end up to fish. When they deposit on grass fields or crop, they typically enter the cattle feed and then milk or meat. Because of this long process including accumulation in food chain, the dioxin exposure of a population is mostly derived from other than local sources. | |||
Margni and coworkers have estimated an iF for Western European sources. The iF is approximately 3.5.10(-3) for emissions of dioxin in Western Europe. This iF compares well to the traditional non-spatial multi-media/-pathway model predictions of 3.9.10(-3) for the same region and to 2.10(-3) for the USA. Approximately 95% of the intake from Western European emissions occurs within the same region, 5% being transferred out of the region in terms of food contaminants and atmospheric advective transport. (Margni et al., 2004) However, when the emission source is in the North-Eastern corner of Europe like Hämeenkyrö is, the population exposed is likely smaller than on average, especially because the predominant wind direction is from southwest and away from densely populated areas. Therefore, the published value is likely an overestimate. | |||

Revision as of 20:05, 21 September 2006
Risk assessment on Hämeenkyrö municipal solid waste incinerator contains a structured risk assessment of a plan to build a MSWI in Hämeenkyrö. There will be a public vote related to a city planning decision: whether the municipality should plan an area for the plant or not. The vote will be held in November 19, 2006.
Objective
RA of Hämeenkyrö MSWI
Empty variable template
General variables
Optimizing rules
- Precautionary principle (disagreement)
