We'd like to find out about air pollution around the world. How does it affect your daily life? Share your views and experiences

Air pollution has risen by 8% in in five years with fast-growing cities in the developing world worst affected, according to the WHO. We want to explore its impact on the daily lives of people around the world. If you live in a city that is affected by toxic air or you work in air quality control, we'd like to hear from you.

Two weeks ago, India's capital city, New Delhi, was effectively shut down because of air pollution. The threat to citizens from smog in Delhi was judged so great that traffic was rationed, coal-fired power stations closed and diesel generators suspended. This week schools were closed in Iran's capital, Tehran after a blanket of smog was blamed for a string of deaths and in Beijing, students have been told to stay indoors. Air quality in London is among the worst in Europe, and is illegally in breach of EU limits.
