I didn't go and look up the others but this argument by similarity, at least when applied to asbestos says the exact opposite to the claim you're trying to make. It's generally considered that industry/government was aware of the issues relating to asbestos in the '30s (and _started_ doing things about it then) but it wasn't until the 70's/80's (depending on the country) that its use was mostly stopped (and in places like Australia it wasn't outright banned until 2003).
