The median sulphate reduction rate is —0.89 peq yr The decrease of sulphate concentrations started at the beginning of the 1980s, quickly after the beginning of the improvement of the air sulphur oxide concentrations, suggesting a fast chemical response of the lakes. The thin soil and the relatively small sulphur storage, typical for high altitudes, surely contributed to the rapid response in most of the studied lakes.

Air-dry samples thoroughly at room temperature, which should not exceed 40°C (loss of Hg ) place the sample on the bag and turn over as necessary. Use gloves Any residual humidity will promote anaerobic reactions, including sulphate reduction, and must be avoided. When samples are properly dried, transfer to a new bag, if necessary (field bag may still be wet), seal and send to LAB IV.
