Is the high air pollution due to population density or emissions technology (ie Diesel vs Petrol?) For example, I look up the pollution numbers for 2015 in Cali

Is the high air pollution due to population density or emissions technology (ie Diesel vs Petrol?) For example, I look up the pollution numbers for 2015 in California Bay Area and the strict California PM10 limits were exceeded for only 2 days in the year.* And California is known for being car crazy and we have had hot dry weather for some time now.

- maelito 11y agoThe proximity of the sea might be one reason. Check www.airparif.asso.fr for the numbers !
- pkaye 11y agoThat would make sense. In California, there is the Central Valley which is far from the ocean but lower population density and the pollution is much worse.
- weddpros 11y agoyou can find current data at http://www.airparif.asso.fr/en/stations/index http://www.airparif.asso.fr/en/stations/index including pm10 measurements
