Influence of Precipitation on the Spatial Distribution of 210Pb, 7Be, 40K and 137Cs in Moss
Autor: Kayla Wilkins, Hazel Cathcart, Padraig Hickey, Olwyn Hanley, Luis León Vintró, Julian Aherne
Publikováno v: Pollutants, Vol 3, Iss 1, Pp 102-113 (2023)
Mosses have been widely used as biomonitors of a variety of atmospheric pollutants, including radionuclides. Here we determine the radionuclide activity concentration of 210Pb, 137Cs, 7Be, and 40K in moss tissue (Hylocomium splendens) collected from

Long-term declines in atmospheric nitrogen and sulfur deposition reduce critical loads exceedances at multiple Canadian rural sites, 2000–2018
Autor: Irene Cheng, Leiming Zhang, Zhuanshi He, Hazel Cathcart, Daniel Houle, Amanda Cole, Jian Feng, Jason O'Brien, Anne Marie Macdonald, Julian Aherne, Jeffrey Brook
Daily air concentrations of inorganic nitrogen (N) species, including gaseous HNO3 and particulate-bound (p)NH4+ and pNO3-, and sulfur (S) species, including SO2 and pSO42-, and precipitation concentrations of NO3-, NH4+, and SO42-, have been routine

Makar, Isaac Wong, Philip Cheung, Hazel Cathcart, Pegah Baratzedah, Ken Scott, Ayodeji Akingunola, Qiong Zheng, Balbir Pabla, Yayne-abeba Aklilu, Amanda Cole, Alain Robichaud, Junhua Zhang
Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 9897-9927 (2018)
Estimates of potential harmful effects on ecosystems in the Canadian provinces of Alberta and Saskatchewan due to acidifying deposition were calculated, using a 1-year simulation of a high-resolution implementation of the Global Environmental Multisc

Critical loads of acidity for 90,000 lakes in northern Saskatchewan: A novel approach for mapping regional sensitivity to acidic deposition
Autor: Julian Aherne, Dean S. Jeffries, Hazel Cathcart, Kenneth A. Scott
Publikováno v: Atmospheric Environment. :290-299
Atmospheric emissions of sulphur dioxide (SO2) from large point sources are the primary concern for acidic deposition in western Canada, particularly in the Athabasca Oil Sands Region (AOSR) where prevailing winds may potentially carry SO2 over acid-
