Metal burdens in two species of fiddleheads growing near the ore smelters at Sudbury, Ontario, Canada
- Laurentian Univ., Sudbury, Ontario (Canada)
The usefulness of selected plant species as potential bioindicators of environmental metal pollution has been clearly demonstrated. High levels of contamination within soils of the Sudbury, Ontario region are characteristically reflected in elevated plant burdens reported for the area. Previous studies investigating plant uptake of metals from Sudbury-area soils have been complicated, however, by the contribution of direct atmospheric deposition onto the foliage. The present study examines metal burdens in two fern species, Interrupted fern and Ostrich fern, resulting solely via root uptake from the soil, thus seeking to assess the indirect influences of the Sudbury-area smelters. The above condition was ensured by collecting the ferns immediately after appearance in the spring while they were still tightly curled and protected from aerial contamination of by the external wooly pubescence.
