Environment Bill

My noble friend raises an incredibly important point and I have to be honest and say that I cannot give him an authoritative answer. He is right that the synergistic effect of mixing chemicals creates entirely new qualities, and two relatively harmless chemicals, or not particularly dangerous chemicals, mixed together can create something that is lethal. A decent, proper and thorough regulatory system absolutely would test new chemicals as they enter the market on the basis of how they are likely to interact with chemicals that they are likely to meet. I am afraid this is not an area I have any expertise in, but I will look into it as a matter of urgency, and I will write to him and place my answer in the Library.
