Use the ICA to determine how much time to spend outdoors. Local television and radio as well as digital sources will often publish the results online.ĭo not go out when there is a lot of pollution. Because of this, air quality has improved during the last two decades. The Environmental Protection Agency (EPA) regularly measures the air quality of cities and rural areas and reports on it. Can anything be done to protect yourself against the poor air quality in Raleigh?
In rural areas, outdoor air pollution is often caused by dust from tractors ploughing fields, trucks and cars driving on gravel roads, rock quarries, and smoke from wood fires and burning crop residue. Construction vehicles and tobacco smoke can also cause it. This combination traps pollution in the air.Īeroplanes also produce a considerable amount of air pollution. Tropospheric ozone increases in cities when the air is not moving, the temperature is warm, and the sun is shining. Ozone is a gas and accounts for a large part of air pollution. This is called ground-level ozone (or urban smog). For example, in a city, air pollution can be caused by emissions from vehicles. Regular exposure to it can harm our health when we breathe it. Outdoor air pollution can be a mixture of natural and man-made particles found in the air. The reason for this trouble with indoor air quality is that the insulation on buildings makes it harder for the contaminants that build-up inside to escape as fresh air replaces stale air. Indoor air can be three or four times worse than the air outside. This is in fact the exact opposite of the truth. People tend to think that the air inside a building is so much cleaner than the outdoor air. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal. Particle pollution often contains soot (BC) or tiny particles PM2.5 and PM10 that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. This is in keeping with a trend seen across the nation of higher ozone pollution levels. What is the source of air pollution in Raleigh?Ĭompared to the 2017 report, some North Carolina metro areas have seen an increase in ozone (O 3) pollution slightly.
In 2017 Raleigh attained the WHO target of 9.4 µg/m³, in 2018 it was 9.8 µg/m³ whereas in 2019 the slight decline revealed a figure of 11.3 µg/m³. Looking back over previous years, the quality is getting slightly worse. For the remaining 5 months, the air quality was “Good” with figures between 10 and 12 µg/m³. For May, July, September and November the readings showed a “Moderate” quality of air with measurements between 12.1 and 35.4 µg/m³. Looking back at figures from 2019, it can be seen that during the months of March, April and October, Raleigh, once again, achieved the WHO target figure. During July and December, the quality was slightly worse with figures between 12.1 and 35.4 µg/m³. In March, June, August, October and November, Raleigh enjoyed “Good” quality air with readings between 10 and 12 µg/m³. It achieved this number for 5 months of the year. In 2020, according to figures just released on the IQAir website, Raleigh recorded an average total of 9.8 µg/m³ which is less than the WHO target of 10 µg/m³. Does the air quality in Raleigh vary throughout the year? It is seen to be one of the fastest growing cities in the US. The 2019 census estimated the population as being slightly less than half a million people. It is informally known as the "City of Oaks" for its many oak trees, which line the streets in the heart of the city.
