On the Gap Grapevine, people are currently discussing The Brisbane City Council’s use of pesticides to eradicate possible crazy yellow ant nests in our suburb with the treatment zone ranging from Arkana to Romea streets. Many are concerned about the impact of such substances on the native wildlife and humans, but others point to the impact the crazy ants could have on wildlife and humans too. Similarly, in the scientific literature this week there was a new report published about common weedkillers and their impact on human health, with evidence that these substances are taken up by the body causing oxidative stress. Given our project of re-introducing the Platypus to The Gap, measuring both herbicide and pesticide burden in the waterways will be important. As residents of the Gap, consideration of the sensitive environment needs to be on the forefront of our minds when we plan to use such chemical substances to control weeds or pests.
