Great Barrier Reef: scientists find high levels of pesticides and blast chemical regulator

Pesticides found in reef catchment include Atrazine, a herbicide banned in 60 countries

Leading marine scientists have detailed a litany of "serious deficiencies" by Australia's chemical regulator that have failed to prevent the ongoing pollution of the Great Barrier Reef catchment, where they found excessive levels of several pesticides banned by other countries.

A new paper, co-authored by reef water quality expert Jon Brodie and fisheries veterinarian Matt Landos, found that pesticide regulation and management in the reef catchment areas of Queensland had failed to prevent the exposure of ecosystems to the significant risk of agricultural chemicals.
