Abstract: [Extract] This component of the Marine Monitoring Program provides an understanding of nearshore pesticide profiles and the exposure risk to marine organisms, as a part of water quality condition on the Great Barrier Reef. Data are collected from eleven fixed monitoring sites located in four Natural Resource Management regions — the Wet Tropics (five sites: Low Isles, High Island, Normanby Island, Dunk Island and Lucinda), Burdekin (one site: Barratta Creek), Mackay-Whitsundays (four sites: Repulse Bay, Flat Top Island, Sandy Creek and Sarina Inlet) and Fitzroy (one site: North Keppel Island). The suite of pesticides monitored includes photosystem II (PSII) inhibiting herbicides (such as diuron, atrazine (and its metabolites), ametryn, hexazinone, tebuthiuron), which all affect photosynthesis, and are commonly detected due to their high usage in adjacent catchments, and their high solubility. Other pesticides monitored include those that have non-photosynthetic effects (such as imidacloprid and metolachlor) and knockdown herbicides (such as 2,4-D).
