Air Quality in Shanghai

When I arrived in Shanghai on Friday night, the air was crisp and clear. Saturday I hardly noticed. Sunday was a beautiful day in the low 70s/high 60s and walking around all day I didn’t notice a thing. Then came Monday. And Tuesday. And now Wednesday. The air smells like I imagine chalk would taste. It’s really quite a thing, after a full day of walking around my eyes start to sting and my throat starts to burn a bit. We theorized that it has to do with the fact that over the weekend there arn’t as many cars on the road so the air can clear out, but during the week the roads are jam packed with traffic and I’m sure factories in town are operating at full steam.
