NZ EPA consultation on a brand new toxic, endocrine disrupting herbicide ends next Wednesday. Strangely, the EPA drew from European info but then deviated to contradict the EU position. psgr.org.nz/pub-res/nzep...

We’re familiar with the commercial and in confidence nature of chemical formulations from personal care products to pharmaceuticals and pesticides, the formulation for AI LLMs are also confidential in nature, enshrined in silico.

It is not your saviour. It is a tool. The black box of AI.

Discernment and critical thinking are key when interacting with an addictive platform that can hallucinate, reflect the bias of management, and which is error-prone.

In 2020 the NZEPA stated that they were looking to reassess the neurotoxic fumigant chlorpyrifos-methyl, but they discretely separated that out in the recent review of chlorpyrifos. 😟https://www.epa.govt.nz/news-and-alerts/latest-news/first-step-towards-reassessing-controversial-insecticide/

www.epa.govt.nz

PSGRNZ @psgrnz.bsky.social · Sep 9

Is chlorpyrifos-methyl a risk to infants & children? The evidence suggests this. But NZ & Australian regulators have steered away from frankly assessing the individual & combined toxic risk of the insecticide & the fumigant. Families are let down by the 'safety' agencies psgr.org.nz/component/jd...

PSGRNZ @psgrnz.bsky.social · Sep 9

NZ EPA only looked at chlorpyrifos - chlorpyrifos-methyl ignored. They could have elected to look at both as a risk class (like they often do when weakening and extending restrictions for other substance classes) but chose not to. It was a political choice. psgr.org.nz/reports-pape...
