This week, Paris recorded the worse air quality in 10 years with a spike in airborne pollution of particles measuring less than 10 microns (PM10) equal to 80 ɥg/m3 (Willshire, 2016 The Guardian)
French air quality norms are set to PM10 < 50 ɥg/m3 (daily mean) with an alert threshold of 80 ɥg/m3 (AirParif).
As a result, public transportation in Paris is operating free of charge, and an odd/even car use ban. similar to that which operates in New Delhi, was implemented to combat air pollution, under virtually windless conditions.
This means that only cars with odd license plates could operate on Wednesday, Dec. 7, 2016, whereas only cars with even license plates could operate on Thursday, Dec. 8, 2017. Today, the car use ban is still effective with only odd license plate vehicles allowed to operate (carpool, emergency vehicles, hybrids and EV excluded). (Sharman, 2016 The Independent). And the same sort of ban has been implemented in the city of Lyon.
The spike in Paris air pollution was determined due to a combination of factors: household heating, transportation exhaust and windless weather conditions.
According to The World Health Organization (WHO) :
Ambient (outdoor air pollution) in both cities and rural areas was estimated to cause 3 million premature deaths worldwide per year in 2012; this mortality is due to exposure to small particulate matter of 10 microns or less in diameter (PM10), which cause cardiovascular and respiratory disease, and cancers

I want you all to help me thank Dr Irosi for saving my life, i was diagnosed of HIV and at the same time i was 7 months pregnant, i was confused and i didn't know what to do until i meant a friend on the Internet who directed me to Dr Irosi, i did not believe it until i contacted the good man who was able to help me out of the situation with his herbs, it only cost me some little amount of money for me to cure my HIV through the help of Dr Irosi. So i will also advise anybody that needs help from him should contact him because i know you will also get cured of your disease. Thanks once again Dr Irosi.
