Indoor Air Quality
More people are now spending more time indoors due to COVID-19 and new working from home arrangements, it is important to be aware of internal air pollution sources in order to reduce exposure where possible. Internal pollution can come from a variety of sources such as heating, cooking, damp, cleaning products and furnishings.
What is air pollution?
Air pollution is the presence of harmful chemicals or compounds in the air that at high enough levels can cause harm. In the case of internal air pollution, these pollutants can come from external and internal sources that build up and negatively impact on human health.
Children, elderly, pregnant woman and those with pre-existing conditions such as asthma, chronic obstructive pulmonary disease (COPD), and cardiovascular illnesses are most vulnerable to air pollution.
The main pollutants of concern include:
Nitrogen dioxide (NO2) – a gas produced from the burning of fuel and transport. Indoor sources of NO2 include:
- Gas, coal or wood fuelled cooking and heating appliances
- Open fireplaces
- Smoking
- External sources such as vehicle emissions that may enter the building
Particulate matter (PM) – a mixture of tiny solid and liquid particles suspended in the air. Indoor sources of internal PM include:
- Cooking activities such as frying
- Cleaning activities
- Open fires
- Smoking
- Aerosols
- External sources such as vehicle emissions that may enter the building
Volatile organic compounds (VOCs) – organic chemical compounds whose composition makes it possible for them to easily evaporate to air. Indoor sources include:
- Cleaning products
- Air fresheners
- Perfumes
- Paints & Paint strippers
- Varnishes
- Glues
- Smoking
- New furnishings such as carpets, furniture, cabinets and flooring.
Carbon Monoxide (CO) – a colourless, odourless gas produced by the incomplete combustion of fuels. Indoor sources include:
- Gas and solid fuel appliances if not ventilated properly or working efficiently
- Smoking
- Candles
- Vehicle emissions that may enter the building
Mould – a fungus caused by moisture, condensation and damp
What are the impacts of these pollutants on my health?
Poor air quality can have short-term and long-term impacts on our health. Some impacts may not be felt until later in life.
Short-term impacts of air pollution exposure can cause Inflammation of the airways leading to:
- Coughs
- Respiratory infections
- Reduced lung function
- Shortness of breath
Elderly and young and those with pre-existing conditions are the most vulnerable whilst healthy individuals may not experience any symptoms.
Long-term impacts of air pollution exposure can result in:
- Coronary heart disease
- Stroke
- Lung cancer
- Reduced lung function in children
- Childhood asthma
- Chronic obstructive pulmonary disease (COPD)
- Diabetes
- Low birth weight
- Lung cancer
- Dementia
Things you can do to reduce internal air pollution
- Use your central heating or electric heaters for warmth. Consider an electric fireplace that provides the aesthetics and warmth of a fireplace without the harmful emissions.
- Avoid smoking indoors. If you must smoke, ensure you do it outside with the door and windows of your home shut.
- Use passive aroma options such as essential oil sticks, freshly cut flowers or dried lavender/potpourri instead of burning candles, incense or using mechanical scent diffusers.
- Ensure your boiler is well maintained and serviced per the manufacturer’s recommendations.
- Make sure your kitchen extractor is on when cooking and is kept on for at least 30min after cooking has finished.
- Make sure your kitchen is well ventilated when cooking.
- Ensure pan and pot lids are used when cooking or boiling.
- Consider eco-friendly cleaning products with no or low VOC content.
- When installing new furnishings or carpets, painting or renovating, keep the room well ventilated for as long as possible. Weeks/months is preferable as the chemicals may take some time to escape.
- If you live near a busy road, avoid opening windows fronting the main road during peak congestion times.
- Consider investing in a vacuum with a HEPA filter and vacuum regularly.
- Remove black mould with bleach or an appropriate fungicidal spray. Please note that the chemicals to kill black mould will likely have VOC’s so make sure the room is properly ventilated.
