Bioher is a research project coordinated by KTL. The duration is 2008-2011. Project includes five subprojects with 1) measurement of PM and greenhouse gas emissions, 2) chemical characterization and assessment of atmospheric thermal impact of emitted PM, 3) toxicological characterization of emitted PM, 4) assessment of exposure to and health effects of current residential wood combustion, 5) assessment of health risks. This assessment page includes scope, definition, and result of health risk assessment of fine particles of four residential heating scenarios (more detailed later).

Scope
Purpose
The purpose is to evaluate PM2.5 and green house gas (GHG) emissions of detached houses and small heating power plant, to assess exposure and health effects due to evaluated emissions and to define emission, heating and health effect costs. Assessment is going to compare four alternative ways to arrange decentralised energy production in communities with 2000 - 10000 inhabitants: light oil and pellets as fuel of detached houses and heavy oil and wood chips as fuel of small heating plants. In addition, environmental effects i.e. climate change (CC) of PM2.5 and GHG emissions is assessed with this model.
Questions:
- What would be the health effects of PM2.5 emissions of small power plant and individual houses in small living area (2000- 10000 inh.)?
- What are GHG emissions of individual houses and small power plant and how emissions effect on CC?
- What are the costs of different alternatives?
- What is the optimal decision to produce energy and heat to houses?
