Ontario's Experimental Lakes Area (ELA) is a sensitive region for heavy metal contamination due to long-range atmospheric deposition from industrial sources. This dataset reconstructs historic mercury and heavy metal deposition from lake sediment cores, likely collected by Environment and Climate Change Canada. The data was last updated on March 16, 2026.
Use Cases
- Analyze trends in historic mercury deposition based on lake sediment core data
- Model long-range atmospheric transport of heavy metals based on the region's downwind location from industrial sources
- Assess the impact of historical gold mining activities on local contamination
- Support regulatory actions and policy development for air pollution based on the Climate Change and Air Pollution program's objectives
Strengths
- Focuses on a remote, sensitive region ideal for studying atmospheric deposition
- Data is associated with the Climate Change and Air Pollution (CCAP) program established in 2016
- Last updated on March 16, 2026
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
