Environmental and health effects caused by fires - Estimating the contribution of accidental fires to the overall environmental impact in the county of Västerbotten

The purpose of this study was to examine the extent of emissions of volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and dioxins, caused by fires, and the relative environmental impact of fires compared with other sources to the county of Västerbotten, Sweden. Estimated levels of fire impact in Västerbotten were based on previously estimated emission levels of VOCs, PAHs and dioxins from fires occurring in 1999 in Sweden. An average of the number of fires and levels of VOCs, PAHs and dioxins generated by other emission sources into the air in the county of Västerbotten was also taken into account. By comparing emission levels of fires and the emission levels of other sources in the county of Västerbotten, the results showed that among other things, dioxin levels from fires were estimated to be as large as emissions from the transport sector. PAH levels in fires are equal to emissions from the energy supply in Västerbotten, such as thermal power stations etc. However, fire emissions of VOC are only 10% of compared to the international air- and sea traffic emissions. Overall, emissions of VOC, PAH and dioxins caused by fires are negligible in comparison to the total environmental impact in the county of Västerbotten.
