I know I've written it before, but we're really witnessing the endgame for endosulfan in Geneva this week. I'm here, once again, for negotiations under the Stockholm Convention, otherwise known as the POPS treaty. The global agreement bans the worst of the worst chemicals — Persistent Organic Pollutants like dioxins and PCBs. As I've been chronicling in this blog, endosulfan has been winding its way through the Convention's evaluation process for several years now. If the stars align, it'll finally be added to the Convention this week, triggering a global phaseout.
