INGENIOUS: Understanding the sources, transformations and fates of indoor air pollutants

Many of the activities we do in our own homes produce airborne pollutants, including particles and chemicals that can be harmful to our health. We don’t know exactly where all of these pollutants come from, how they interact with each other or where they end up. The INGENIOUS project will investigate these unknowns and deliver useful interventions to limit exposure. It focuses on homes in the city of Bradford, UK.

Why do we need to understand indoor air pollution?

UK residents spend around 90% of their time indoors, yet regulations to address air pollution focus almost solely on outdoor exposure. Indoor air pollution takes many forms, from particulate matter such as dust and soot from wood burners to gases like carbon monoxide from gas stoves. Breathing in these particles and gases are bad for our health and poor indoor air quality has been linked to lung diseases including asthma, cancer and chronic obstructive pulmonary disease.

About the project

SEI is taking part in a £2.9 million UK Research and Innovation (UKRI) project to better understand how the composition and concentration of indoor air pollutants vary and how this exposure affects people in their homes.

The project will focus on homes in the city of Bradford, which, like many other parts of the UK, is affected by poor air quality. Bradford has a multi-ethnic population and high levels of deprivation, with some of the highest childhood illness rates in the UK.

This animation introduces the project and explains what is involved for participants. Production: Digifish.

A team of scientists from four universities, including SEI York based at the University of York, will work with the Bradford Teaching Hospital NHS Foundation Trust and Born In Bradford study – a long-term research programme following children born in the city – to better understand the potential impacts of poor indoor air quality on ill health.

The team will quantify and identify:

  • the composition and concentrations of air pollutants within indoor spaces, such as those from cooking and cleaning;
  • how air pollutants react chemically and transform over time, including when different air pollutants mix;
  • how air pollutants from indoor air sources affect outdoor air quality and vice versa;
  • how different household behaviours affect the production of and exposure to air pollutants and how this affects health outcomes and inequalities;
  • which behaviour change interventions are most effective at reducing exposure to indoor air pollution; and
  • which recommendations to take forward as policy solutions.

SEI York’s contribution will focus on the co-production and evaluation of behaviour change interventions and the development of policy recommendations. To do this, SEI will communicate with homeowners, tenants and communities about the risks associated with indoor air pollution exposure and the actions they can take to reduce their exposure.

SEI will also work with local authorities, planners and developers to identify suitable policy recommendations for addressing this issue in homes across the city and provide a blueprint for applying these measures in homes and businesses across the UK.

“This study is the first of its kind to look in such detail at the pollution inside people’s homes in the UK, particularly focusing on poorer households. At SEI, we will be using our strengths in policy engagement and citizen science to work with decision-makers and local residents to identify how householders and local authorities can reduce exposure to air pollution in the home.

Once we have examined the different behaviours that influence a person’s exposure to indoor air pollution, for example, using fans whilst cooking or opening windows to increase ventilation, we will then provide advice to householders and local authorities on the changes they can make to improve air quality in the home.”
