Last week was a very bad week to be in Shanghai. We had the worst pollution here, ever, as far as I can gather. There are lots of different numbers thrown around, but pretty much everyone agrees that the PM2.5 count went above 500 last Friday (December 6, 2013). Just to put that “500″ in perspective:
WHO guidelines say average concentrations of the tiniest pollution particles – called PM2.5 – should be no more than 25 microgrammes per cubic metre. Air is unhealthy above 100 microgrammes and at 300, all children and elderly people should remain indoors.
My favorite tool for following pollution levels is the Graphing Air Pollution in China page at kopf.github.io/chineseair/. Here’s a screenshot highlighting the peak last Friday (Shanghai in red, Beijing in blue):
By coincidence, I went outside on Friday night (close to the peak) to pick up some milk at the store. It’s a 5-minute walk to the nearest Family Mart. As soon as I stepped outside into the haze, I noticed that the air smelled faintly burnt. I say “faintly,” but it’s the kind of “faintly” that gets incredibly obvious the more you smell it. Meanwhile, the air just felt grimy. Beijing has had some terrific pollution in its day, but Beijing air tends to stay quite dry. Shanghai, meanwhile, is incredibly humid. It makes summers super sweltering, winters bone-chilling, and smoggy days absolutely disgusting.
I’m actually not very sensitive to the pollution, and when people ask me how bad it is, I don’t have a lot to say. It just doesn’t bother me that much. This latest uber-smog, though, got to me. In the 5-minute walk to the store, I started to feel a little queasy. In the 5-minute walk back home, I was feeling sick to my stomach.
So yeah, it was really bad. If it was like this every day, or even routinely, I wouldn’t want to live here anymore. I seriously hope China can take effective measures against this horrific pollution. Right now I’m seriously looking forward to my Christmas trip to Florida. Besides the precious family time, I could also use a little lung detox.
