What are the potential environmental risks associated with the use of nanopestcides? by Ruth Cooper https://padlet.com/rcooper216/er05nao8wne2bgr5 en-us 2021-02-15 14:24:50 UTC 2025-10-03 10:35:25 UTC hello@padlet.com https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207149030 Slow release of the pesticide from the capsule means exposure may be longer than a spray ?]]> 2021-02-16 14:42:17 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207149030 https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207252733 Increased solubility may increase risk of run off into aquatic environments]]> 2021-02-16 15:05:46 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207252733 https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207340380 Greater durability may mean the pesticide remains in the environment for longer before it is degraded. Potentially causing the pest population to be subjected to the selection pressure for longer, so the development of resistance may occur sooner than traditional pesticides. ]]> 2021-02-16 15:24:20 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207340380 Harder to detect bioaccumulation. Have seen other nanoparticles (plastics) build up over time - may not be at detectable level yet. https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207374533 2021-02-16 15:31:31 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207374533 How can we remove these from the environment. https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207377398 2021-02-16 15:32:09 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1207377398 Nano-pesticide risk https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210506386 If they are more durable, they may persist for longer in the environment. Also, if they have higher solubility, this may mean higher concentrations of the pesticides reach aquatic environments. ]]> 2021-02-17 10:16:12 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210506386 Issues around sourcing the inorganic materials for these nanopesticides mtarrant3 https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210655539 Use of metals - how will these be sourced? This could potentially increase pressure to conduct seabed mining to extract the metals for these pesticides. Their increased solubility could subsequently exacerbate these impacts on aquatic ecosystems, so would need to be carefully controlled. ]]> 2021-02-17 11:12:02 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210655539 70 years ago we thought the pesticides of the time were wonderful and now we realise they do enormous damage - so nano-particles seem to be a repeat of this, using pesticides that last longer (and though at lower does, we know low doses are still harmful) - once again we think we've found a shiny solution to our self-made problem, which in time will no doubt be as bad, if not worse, than the original. Such is human nature! https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210679540 2021-02-17 11:22:00 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1210679540 I think a big problem with nano pesticides is how they are likely to stay a long time in the environment and be difficult to detect. Although currently we are not aware of whether they are dangerous or not, if they are, the time, money, resources and research needed to remove them from the environment will be very high and it could even be completely impossible to remove them. https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1211757537 2021-02-17 16:12:12 UTC https://padlet.com/rcooper216/er05nao8wne2bgr5/wish/1211757537
