Soil Neonicotinoid Concentrations Across 38 Sites in Southern Ontario

The Ministry of the Environment, Conservation and Parks initiated the Multi-Media Monitoring Study in 2015 to measure changes in neonicotinoid insecticide concentrations following restrictions on treated seeds. This dataset characterizes neonicotinoid concentrations in soil at 38 study sites across five southern Ontario watersheds. The data is part of Ontario's Pollinator Health Action Plan and is available in CSV, HTML, and PDF formats.

Use Cases

• Analyze trends in soil pesticide concentrations based on data from 38 sites over time
• Assess the environmental impact of agricultural seed-use restrictions based on measured neonicotinoid levels
• Correlate soil contamination with watershed characteristics based on the five specified southern Ontario watersheds
• Support policy evaluation for pollinator health initiatives based on longitudinal monitoring data

Strengths

• Data collection began in 2015, providing a longitudinal record
• Samples from 38 distinct study sites across five watersheds
• Part of a coordinated Multi-Media Monitoring Study with related datasets for water and invertebrates

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to its focus on southern Ontario
