Methane consumption was measured in Forest soils of Poland in areas of high
regional air pollution (SO2 loads) and compared to the activity in areas o
f low air pollution loads. The areas include the regions with the highest i
nput of SO2 found in Europe acid cover a range of average acid deposition u
p to a factor of 10. No distinct pattern of methane oxidation activities wa
s identified that could be related to present or previous SO2 loads. Methan
e consumption activity ranged between 16 and 110 mug CH4 m(-2)h(-1) similar
to the activity encountered in previous studies of forested areas. (C) 200
