摘要:
Precipitation samples in Alberta were collected and analyzed monthly from six Alberta Environment stations. Samples were collected with Sangamo samplers and analyzed for the major ions, pH and acidity. The data were tabulated and analyzed for spatial distribution, seasonal variation, temporal trends, ionic character and wet sulfate deposition. The major ionic species in Alberta precipitation are Ca**2** plus , SO//4**2** minus , NH//4** plus and NO//3** minus . The spatial distribution shows a slight decrease in pH from southern Alberta (pH 6. 0) to northern Alberta (pH 5. 4). The seasonal variation shows higher hydrogen ion content in the summer months (pH 5. 4 in summer and pH 5. 8 in winter).
