In the analyses of sediment and intertidal seagrass samples from along the Queensland coast in 1997 and 1998, Haynes et al (2000a) found atrazine between 0.1 and 0.3ug/kg, and diuron from 0.2 to 10.1ug/kg (up to 1.7ug/kg in seagrass). The highest levels were mainly in samples collected along the high rainfall, tropical coast between Townsville and Port Douglas and in Moreton Bay.
