The interaction of atmospheric sulphur (S) was investigated within the canopies of two boreal forests in Qu\u00e9bec, Canada. The net canopy exchange approach, i.e. the difference between S-SO4<\/sub> in throughfall and precipitation, suggests high proportion of dry deposition in winter (up to 53%o<\/sub>) as compared to summer (1-9%). However, a 3.5%o<\/sub> decrease in d18<\/sup>O-SO4<\/sub> throughfall in summer compared to incident precipitation points towards a much larger proportion of dry deposition during the warm season. We suggest that a significant fraction of dry deposition (about 1.2 kg ha-1<\/sup> yr-1<\/sup>, representing 30-40% of annual wet S deposition) which contributed to the decreased d18<\/sup>O-SO4<\/sub> in throughfall was taken up by the canopy. Overall, these results showed that, contrary to what is commonly considered, S interchanges in the canopy could be important in boreal forests with low absolute atmospheric S depositions.<\/p>\n","protected":false},"excerpt":{"rendered":"
