Few pesticides in Tasmanian water
Water monitoring in the Australian state of Tasmania shows that streams and rivers are free from unsafe levels of pesticides, the industry association, CropLife Australia, points out. Testing for 18 pesticides at 55 sites last month showed that only two samples contained measurable levels of pesticides. One contained the fungicide, metalaxyl, at 0.42 µg/litre and the herbicide, metribuzin, at 0.18 µg/litre. Another contained metalaxyl at 0.5 µg/litre. The quarterly monitoring programme has been running since 2005 and the vast majority of samples have had no pesticide residues.
