Air quality analysis

Case study

We observed the pollution levels in Lombardia (Italy) from 2006 to 2018. We decided to study 2 different relations:

• Relation between pollution and weather conditions
• Relation between pollution and deseases

We made a dashboard using plotly, a powerful Python module. Here is the list of the pollutants we analyzed:

• PM 10
• PM 2.5
• NO2
• O3
• SO2
• CO 8h
• C6h6

Weather conditions

We checked if different weather conditions affected the pollution levels in Lombardia. Using the dashboard, a user can choose the pollutant and a weather condition between:

• Humidity
• Temperature
• Wind speed
• Global radiation
• Precipitation

The dashboard will show the "scatter plot" between the chosen elements.

Deseases

We checked if a specified pollutant affected the number of deaths for a given desease in Lombardia. Using the dashboard, a user can choose the pollutant and a desease. The dashboard will show the scatter plot between that elements.

Other tabs of the dashboard

• General Tab

Here we displayed a "choropleth map" that clearly shows which province is the most polluted, a "line chart" that shows the pollution trend among the years and a "donut chart" that shows the most prevalent pollutant.

• Specific Tab

Here we displayed an "interactive choropleth map" that permits the user to click to a specific province and analyze the pollution levels for that province in the specified year. Based on the user's click the dashboard shows also a "spider graph" that highlights the pollutant level among the months of the selected year, a "donut chart" like the one explained above that shows the most prevalent pollutant in the selected year and finally a "box plot" and a "area chart" that show the distribution of the pollutant level and if the pollutant exceeded the legally admitted limits.

Datasets used

We took the datasets about the deseases from ISTAT:

• (https://www.istat.it/).

We took the datasets about the weather conditions and the pollution levels from Open Data Lombardia:

• (https://www.dati.lombardia.it/)
