What do you think are the main challenges regarding environmental risk assessment of pesticides? by Ruth Cooper https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt en-us 2021-02-16 12:13:32 UTC 2026-01-17 03:53:10 UTC hello@padlet.com https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207276538 Industry push for unnecessary pesticide use (because money speaks louder); diverging scientific findings detracting attention from certain issues, confirmation bias... ]]> 2021-02-16 15:11:06 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207276538 https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207398586 Balancing the demands of the global population with the effects on ecosystems ]]> 2021-02-16 15:36:47 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207398586 https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207400478 The pressure of forming policies despite not knowing long term effects. ]]> 2021-02-16 15:37:11 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207400478 https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207491502 Pesticides maybe applied as non-toxic dose to crops, a dose which does not impact other other taxa (fish, mammals, birds). However, when the pesticide enters the environment it may interact with other chemicals/toxicants and result in sublethal endpoints. ]]> 2021-02-16 15:56:57 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1207491502 Issues of environmental risk assessments https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1210549663 - Long-term impacts not known 
- Interactive effects of different pesticides
- Different effects on different taxa 
- Cost-benefit analyses of the different chemicals - and maybe new chemicals being used before research has conclusively shown its safety 
- Sub-lethal endpoints which might not be easy to identify ]]> 2021-02-17 10:31:47 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1210549663 https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1210793913 Impossible for ERA to account for all factors in such a tightly integrated system as an ecosystem - and missing just one can lead on to knock on effects throughout the ecosystem. And the only way you will ever know for sure is once you've been applying this poison on an industrial scale, by which point it's too late to do anything about it.]]> 2021-02-17 12:10:29 UTC https://padlet.com/rcooper216/yvu7fdvi2wrm3eqt/wish/1210793913
