BOREAS TGB-07: Rainwater Pesticide Concentrations in a Boreal Forest

Seven herbicides, three herbicides, two insecticide groups, and several polychlorinated biphenyls were measured in rainwater samples collected during two summer field campaigns. Sampling occurred from June 16 to August 13, 1993 and May 4 to July 20, 1994 at a BOREAS site in Prince Albert National Park, Canada. The data supports research into the atmospheric transport and deposition of agricultural chemicals into boreal and arctic ecosystems.

Use Cases

• Estimating yearly deposition rates of agricultural pesticides based on measured rainwater concentration and flux.
• Tracking long-range atmospheric transport of specific herbicides like 2,4-D, atrazine, and trifluralin from agricultural regions.
• Assessing the presence of persistent organic pollutants like DDT and PCBs in remote boreal forest ecosystems.
• Modeling the potential for bioaccumulation of organochlorines in arctic food chains using concentration data.

Strengths

• Provides specific, named chemical analytes, including seven herbicides, three herbicides, two insecticide groups, and several PCBs.
• Covers two distinct summer sampling periods in 1993 and 1994, allowing for seasonal and interannual comparison.
• Collected at a well-defined research site (BOREAS site in Prince Albert National Park) within a protected area.

Limitations

• Key metadata conflicts: last updated date is reported as both 1994-07-20 and 2026-04-10, creating uncertainty about data currency.
• Column names and data structure are unknown, limiting immediate usability and requiring investigation of the actual files.
• The dataset's size, row count, and specific file formats within the listed union (ISO, BIN, TEXT, PDF, HTML, ZIP, PNG) are not detailed.
