Air quality has been in decline in England for the past few years, but there’s been a notable improvement in recent weeks.
Here are the latest air quality data from England’s five boroughs.
How many days is average in a year?
In recent years, average air quality has remained about the same.
But with more people coming to live in London, the capital, there’s a greater chance for a more dramatic change in air quality.
The average air pollution levels in May are now around 30.5 micrograms per cubic metre, down from 36 in March.
What is ‘mild’ pollution?
‘Mild’ air pollution is the lowest level of air pollution that can be tolerated in the UK, at which point the level is no more than the average of the four other levels, including nitrogen dioxide, sulphur dioxide and sulphur monoxide.
This level is set at 10 microgram per cubic centimeter.
How often do the levels change?
The average daily level of daily pollution varies over time.
In May, average daily pollution levels rose slightly from 31.9 microgram to 33.9, although there were many days in which they were lower.
The latest data shows that pollution levels were still well below the ‘very moderate’ level of 32.4 microgram a cubic metre in May.
How can I help reduce pollution?
If you live in a high-rise building or apartment block, consider making sure your building has a ventilation system.
The World Health Organisation recommends that people stay indoors during daylight hours and take precautions such as avoiding outdoor activities such as outdoor cooking.
How does air quality compare to other countries?
In terms of air quality, the UK has a relatively healthy air quality record compared to other European countries, such as Denmark, Germany, France and Spain.
But there are some key differences, according to data from the Organisation for Economic Co-operation and Development.
The UK has higher levels of nitrogen dioxide pollution, which is the main pollutant associated with health problems such as heart disease and lung cancer.
A ‘moderate’ pollution level is the same as in some European countries but there are fewer people living in the country.
For example, people living near the capital are less likely to live within five kilometres of a high rise.
Is there a risk of health problems linked to air pollution?
Air pollution can cause health problems including heart disease, asthma and bronchitis.
There are no known health effects from chronic exposure to air pollutants, but people are more likely to get sick from a short-term or chronic exposure.
Is it safe to travel to London?
It’s recommended that all new construction in London should be completed in the summer, so it’s advisable to stay in a building that has ventilation systems.
London has been experiencing a series of events that have resulted in residents being forced to move to other areas, including Canary Wharf.
What are the symptoms of PM2.5 pollution?
PM2-PM10, or particles smaller than 2.5 micrometres, are a class of pollution that includes nitrogen dioxide and ozone.
These particles are caused by burning fossil fuels and are known to cause lung, skin and eye irritation.
They also can cause bronchial irritation, nose and throat irritation, and asthma.
PM10 is less toxic and is mainly caused by the burning of plastics and plastic products such as packaging, clothes and food.
