Description Research the air quality conditions, current and historically throughout the year, for a particular city. Post a summary of what you find as it relates to the air quality and pollutants discussed in Chapter 2 of the textbook. Two websites that you may find helpful are given below, but you are welcome to use other sources. http://www.airnow.gov/ https://www.epa.gov/outdoor-air-quality-data Peer 1: In the city of Paris, France, the air quality as of 3/9/2020 is good.1-Low pollution index forecast for today.Parisian agglomeration index: 48,due to pollutants: Nitrogen dioxide.2- Concentration of pollutants:The maximum levels on the stations measuring the ambient pollution of the agglomeration include between:* 90 µg / m³ and 120 µg / m³ for ozone (O3)* 90 µg / m³ and 120 µg / m³ for nitrogen dioxide (NO2)* 20 µg / m³ and 30 µg / m³ for particles (PM10)3- Forecaster’s comment:A hot but cloudy day is expected over the region today. An increase in ozone levels is expected, but the pollution index will remain low.2019 ASSESSMENT OF AIR QUALITY IN PARIS:In 2019, chronic pollution levels continue to decline, with the exception of ozone which continues to rise.The Parisians exhibition:With the exception of ozone, the downward trend in chronic pollution levels continues and the intensity of exceeding standards is decreasing year by year. The WHO recommendations are nevertheless largely exceeded, in particular for PM2.5, for which there is a significant difference with the regulatory thresholds.For nitrogen dioxide (NO2), the busiest axes (ring road, A1 motorway, etc.) have average levels which are still close to double the annual limit value (set at 40 µg / m3).
