PM2.5 emissions in Hämeenkyrö

| Argumentation:
←--It is important to be able to compare different risks. Seeing emission values for each sector makes this easier. The new emissions from the plants can then be put into perspective with variables people can perceive: they may have previous experience or a feeling about the amount of smoke coming from homes, or factories.: . --Jouni 06:05, 22 September 2006 (EEST) {{{3}}} (type: truth; paradigms: science: defence)

Dioxin variables
Dioxin emissions in Hämeenkyrö

Landfills should be included in the list of dioxin sources
| Fact discussion: . |
|---|
| Opening statement:
Closing statement: Resolution not yet found. (A closing statement, when resolved, should be updated to the main page.) |
| Argumentation:
←--Dioxins are formed in all combustion in small amounts. Especially when there is chlorine available and the burning temperature is low, the formation of dioxins is high. Even at high burning temperatures, dioxins form when the gases cool down. Uncontrolled burning of landfills is an optimal process for dioxin formation: low temperatures, lack of oxygen which creates large amounts of unoxidised gases and polyaromatic compounds, and abundance of chlorine from salt in food waste. Therefore, landfill fires should be added to the list of dioxin emission sources, and these emissions should be estimated.: . --Jouni 06:30, 22 September 2006 (EEST) {{{3}}} (type: truth; paradigms: science: defence)

PCBs should be excluded
| Fact discussion: . |
|---|
| Opening statement:
Closing statement: Resolution not yet found. (A closing statement, when resolved, should be updated to the main page.) |
| Argumentation:
←--PCBs were a group of oily products that were used in sevaral places until 1980's but that were banned due to their persistence and toxicity. Although PCBs are formed in a poorly controlled burning processes in the same way as dioxins, they are much less toxic compared with dioxins. Therefore, the major concern with PCBs is not the formation in burning but the existing PCBs in building materials, transformers, and other places. PCBs do not bring any significant new understanding to the emissions of the different alternatives, and therefore it should be excluded from the risk assessment.: . --Jouni 06:47, 22 September 2006 (EEST) {{{3}}} (type: truth; paradigms: science: defence)

| Argumentation:
If the decision model will be used to analyse alternative scenarios, we have to include both modelled variables and feedback variables here or alternatively define these own variable for the Pyrkilö -model.

MSWI and dumping site alternatives have diffent total noise and smell effects for people living near the emission source. Both should be analysed before final solution.

Probably it could be possible to use also ash produced by MSWI? In Elimäki new factory was started where they produce forest fertilizer from the ash, which means that ash is not waste any longer but can be used (in case it is clear enough to be spread on the ground). -Sanna

Closing statement: Resolution not yet found. (A closing statement, when resolved, should be updated to the main page.) |
| Argumentation:
←--Short term effects of dioxins only occur when the acute doses exceed the current background exposures by several orders of magnitude. This kind of exposures are not possible in the case of MSWI, and they can be excluded.: . --Jouni 10:33, 21 September 2006 (EEST), Anu {{{3}}} (type: truth; paradigms: science: defence)
