In North Queensland, Russell et al. (1996) reported that diedrin, DDE, 2,4-D and atrazine were detected in between 9 and 27% of samples from the Johnstone and Daintree Rivers…Some herbicide residues were found in only 13% of aquatic fauna samples from Northern Queensland rivers between 1990 and 1993 (Hunter et al. 1996); atrazine and low levels of 2,4,5-T were found in a few samples from the Johnstone River, and 2,4-D was found in both Johnstone and Daintree Rivers (Hunter et al 1996)
