Aquatic ecosystems marinated in a mixture of toxic chemicals?

"Menindee fish kills: inconsistent pesticide levels sparks calls for review of water testing methods. Experts call for review after two sets of water samples from the Darling-Baaka River reported by the state’s top scientific bodies contained different results"

“Atrazine, simazine, tebuthiuron and metolachlor are no longer approved for use in the European Union and have been classified by the European Chemicals Agency as being “very toxic to aquatic life with long lasting effects”, but they are still approved for use in Australia."

"Vincent Pettigrove, a professor of aquatic pollution at RMIT, said while the guideline values provided an indication of whether the chemicals of interest were at concentrations which may cause environmental harm, there were no national guidelines for “the majority of pesticides registered for use in Australia ...The guideline values are for one chemical and were therefore “unable to consider the total effects of a mixture of chemicals”.
