| Abstract: | This study is concerned with an acidic deposition episode which occurred at Dorset in the ecologically sensitive Muskoka-Haliburton area of Ontario during the period 28 August–4 September 1981 when 12 % of the total 1981 precipitation fell. The wet deposition of both the sulfate and free hydrogen ions during this 8-day period accounted for 28% of the total 1981 wet deposition. The wet deposition of nitrate accounted for 16% of the 1981 total wet deposition.A trajectory study implicates pollution sources south and southwest of the study region. |
