What is air_quality_no2.csv and why is it important for air quality?
air_quality_no2.csv is a comma-separated values (CSV) file that contains data on NO2 levels in the air from May 7, 2019 to June 21, 2019. The data was collected by the Ozone Monitoring Instrument (OMI), a satellite-based sensor that measures atmospheric gases. The file has four columns: datetime, station_antwerp, station_paris, and station_london. Each row represents an hourly average of NO2 concentration in micrograms per cubic meter (µg/m) at each station. Some values are missing due to cloud cover or other factors.
What is NO2 and how does it get in the air?
NO2 is a highly reactive gas that is part of a group of nitrogen oxides (NOx). It is one of six widespread air pollutants that have national air quality standards to limit them in the outdoor air. NO2 primarily gets in the air from the burning of fuel. NO2 and other nitrogen oxides in the outdoor air contribute to particle pollution and to the chemical reactions that make ozone. NO2 can also form indoors when fossil fuels like wood or natural gas are burned.
What are the harmful effects of NO2?
Breathing air with a high concentration of NO2 can irritate airways in the human respiratory system. Such exposures over short periods can aggravate respiratory diseases, particularly asthma, leading to respiratory symptoms (such as coughing, wheezing or difficulty breathing), hospital admissions and visits to emergency rooms. Longer exposures to elevated concentrations of NO2 may contribute to the development of asthma and potentially increase susceptibility to respiratory infections. People with asthma, as well as children and the elderly are generally at greater risk for the health effects of NO2.

NO2 along with other NOx reacts with water, oxygen and other chemicals in the atmosphere to form acid rain. Acid rain harms sensitive ecosystems such as lakes and forests. The nitrate particles that result from NOx make the air hazy and difficult to see through. This affects the many national parks that we visit for the view. NOx in the atmosphere contributes to nutrient pollution in coastal waters.
What is being done to reduce NO2. What is being done to reduce NO2 pollution?
To reduce NO2 pollution, various measures can be taken at different levels. At the source, the burning of fossil fuels can be reduced by switching to cleaner and renewable energy sources, such as solar, wind, and hydro power. The use of low-emission vehicles, such as electric cars and buses, can also help lower NO2 emissions from transportation. At the end-user level, the efficiency and maintenance of combustion appliances, such as stoves, heaters, and boilers, can be improved to reduce NO2 emissions indoors. Ventilation systems can also be designed to provide sufficient fresh air and filter out pollutants.
In addition to reducing NO2 emissions, some methods can also help remove NO2 from the air. For example, potted plants can act as natural filters that absorb NO2 and other gases through their leaves and roots. Some studies have shown that certain plants, such as peace lily, spider plant, and snake plant, are more effective than others in removing NO2 indoors. Another way to remove NO2 from the air is by using flue gas denitrification, a process that converts NOx into harmless nitrogen and water using catalysts or biological agents. This technique is often used in power plants and industrial facilities to reduce their NOx emissions.
