Abstract
At three different peat fuelled plants in Finland, environmental studies have been carried out with the aim of obtaining part of the background data necessary for the formulation of environmental guidelines in relation to the future use of peat for energy and heat production in Sweden. The present project was comprised of (a) field studies of the composition pattern of polyaromatic hydrocarbons (PAH) and of heavy metals in the surroundings of some existing peat fuelled power plants, and (b) laboratory tests with a few aquatic organisms to check the possible biological effects induced by emitted particles. The results of these studies indicate that the deposition of (PAH) in the surroundings of three power plants (measured by snow sampling and by analysis of kale grown in the area) did not exceed the background level, whereas the deposition of heavy metals emitted from one power plant resulted in increased concentrations of Fe, Mn, Pb, Zn and possibly of Hg, compared to the assumed background level. Biological tests with particles originating from two different peat fuelled power plants showed that only weak, but obvious, effects could be detected at concentrations corresponding to realistic deposition levels. These effects are supposed to be due to

When evaluating the lab results, it should be considered that a certain fixation of metals dissolved in the snow melting water may take place in the soil surface. Therefore, the biological effect studies, carried out so far, do not indicate that peat combustion at the investigated power plants, using efficient flue gas cleaning systems, cause any considerable biological effects in the surroundings of the plants. However, it is evident that the present set of data does not allow a general evaluation of the over-all environmental impact of peat combustion.}
