This project will investigate pesticide concentrations and trends across 11 sites of the Great Barrier Reef Marine Park Authority (GBRMPA) over the 2022-2023 wet season to determine pesticide impacts on the Great Barrier Reef.
The project will include:
- Time-weighted average water concentrations and spatial distribution of photosystem II herbicides entering the reef catchment areas at sites identified as high-risk areas.
- Provide temporal sampling of the Marine Monitoring Program (MMP) pesticide monitoring that is consistent with previous monitoring data established over the last 2 decades at a subset of the sites for ongoing load estimations.
It is expected this project will provide data to inform pesticide regulation in the Great Barrier Reef catchment areas and assist in developing an ongoing program for assessment of long-term risks from pesticide use.
