About 20 years ago, Kent Anger and Barry Johnson came up with 750 chemicals that could harm the brain during development. Nobody has since dared to update that number. It's just a guess today. There has to be more than a thousand if there was 750 twenty years ago. But the problem is also that we have put too little emphasis on this type of research.
For example, it has taken so far the OECD 10 years to devise a battery of tests that they could recommend for systematic testing of chemicals for developmental neurotoxicity. That panel, that battery, has not yet been completed and authorised by the OECD, so it's taking way, way, way too long because it is complicated. But there is so much at stake.
Children are just losing IQ points and losing their concentration span, memory or motor functions.
Compare the note example
20y ago 750 chems → dev brain harm
now >1,000?
testing slow OECD 10y → unfinished
so children lose IQ + focus + memory + movement
