Shanghai - Post Report Question and Answers
Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Very unhealthy. Better than Beijing, worse than anywhere in the U.S. or Europe. Expect difficulties with athsma if you've got it, and the Shanghai cough during winter months. Don't even think about swimming in local rivers or lakes - though walking on them might be an option. The impact of pollution on food sources is a constant worry. - Feb 2009
Unhealthy to very unhealthy depending on weather/season. - Jun 2008
