It refers to the contamination of the atmosphere by harmful chemicals or biological materials. The fact that it is such a large health risk is backed by the high number of metrics pointing toward air pollution as the primary cause of distress in terms of disease (most deadly of which include cancer) and death. That is to say that the health effects can be both short term and long term. For example, it is estimated that 7 million people died prematurely across the world due to air population. In fact, in the European Union, 400,000 people suffered a premature death. |

It is now a major concern in Bulgaria as to how clean the air you’re breathing right now is. Measurements show that citizens all over the country breathe air that is considered harmful to health. The Organization for Economic Cooperation and Development (OECD) predicts that in 2050 outdoor air pollution will be the top cause of environmentally related deaths worldwide. | It is now a major concern in Bulgaria as to how clean the air you’re breathing right now is.

Problem and Motivation
Dataset Analysis and Transformation Process
Task 1: Spatio-temporal Analysis of Official Air Quality
Task 2: Spatio-temporal Analysis of Citizen Science Air Quality Measurements
Task 3
Urban air pollution is a complex issue. There are many factors affecting the air quality of a city. Some of the possible causes are:
- Local energy sources. For example, according to Unmask My City, a global initiative by doctors, nurses, public health practitioners, and allied health professionals dedicated to improving air quality and reducing emissions in our cities, Bulgaria’s main sources of PM10, and fine particle pollution PM2.5 (particles 2.5 microns or smaller) are household burning of fossil fuels or biomass, and transport.
- Local meteorology such as temperature, pressure, rainfall, humidity, wind etc
- Local topography
- Complex interactions between local topography and meteorological characteristics.
- Transboundary pollution, for example, the haze that intruded into Singapore from our neighbours.
In this third task, you are required to reveal the relationships between the factors mentioned above and the air quality measure detected in Task 1 and Task 2. Limit your response to no more than 5 images and 600 words.
Software
- Tableau - for visualization of the various tasks
- Python - for geocoding
