I was actually inspired to ask this question in certain circumstances. In the outskirts of my city, there happened to be a styrene gas leak early morning today which killed thirteen and hospitalized many people.
Since styrene is an aromatic compound, it is suspected to be carcinogenic in nature but I think it is inert towards other atmospheric gases as well as many compounds in non-laboratory conditions. The temperature here is 31 °C, so it can stay for a large time unaffected at the same area without much spreading. I think so because it has a high molecular weight(104 g/mol).
My question is: "is there a way to treat this styrene in the atmosphere without causing much more toxicity in that area?" (For information regarding its toxicity, refer to this safety data sheet). Of course, I understand that styrene is broken down within 1-2 days in the atmosphere naturally but is there any other way to do it quicker?
