If a chemical behaves in this way, say it’s persistent, it’s bio-cumulative, it’s found in human tissues, and it’s demonstrated to be hormonally active, that that’s it. It’s out of the marketplace. That’s a prohibitive policy.
Once you decide not to employ a prohibitive policy, once you decide not to ban, you basically require the regulatory agency to figure out exactly which uses would be allowed and which would not for UPVC Windows. It creates a very expensive and difficult, time consuming, monitoring and enforcement problem for an agency. So, the regulation chemical by chemical, use by use, is not likely to have much effect in solving a problem such as this.
California is requiring the listing of DEHP under it’s Proposition 65 for UPVC Windows. This was required in 2008. What it’s done is it’s limited the concentration of DEHP in products to less than .01%. Now, what would that do?
