You don’t need to know exactly what it is. You need a mass emission rate. Granted there’s some guess work. You know the mass leaked. You can guess % burned. But you still have to know % combined with oxygen. Still whatever compounds produced by burning are going to be really nasty. The were some fixed site monitors upwind that measured pretty high polycyclic aromatic hydrocarbons (PAHs). I beg there were some chlorinated ones too. The just like regular PAHs, chlorinated PAHs are going to be around for a long time but longer. And Cl-PAHs are going to more toxic and there’s not a lot of good data to derive health benchmarks. We’re going to have to see what diseases pop up for people and ecosystems.
