Study Reveals Indoor Air Pollution Risks from Cooking and Wood Burning in UK Homes
A recent series of studies conducted across the UK have highlighted significant sources of indoor air pollution, particularly from cooking and wood burning.
In Bradford, 310 homes were monitored and cooking, especially frying, was identified as the primary cause of indoor particle pollution. A separate investigation in Nottingham involving 20 homes equipped with Defra-approved wood stoves over four weeks found that wood burning led to sharp increases in indoor pollution levels. These spikes occurred during lighting of the stove, when opening or refueling the stove, and during fire tending.
Parallel findings were reported by Imperial College London and the University of Surrey for homes in south-east England and Cornwall, reinforcing the impact of these activities on indoor air quality.
To reduce exposure to such pollutants, recommendations include refueling wood stoves less frequently, opening stove doors slowly and briefly, and ensuring adequate ventilation. It is advised not to light stoves on days with poor air quality or low wind and to avoid lighting them in the presence of vulnerable individuals. For cooking-related pollution, consistent use of hood fans is encouraged, summarized by the slogan “pan on, fan on.” Reminders mounted on cooker hoods help promote this practice. Ventilation is also key when using cleaning products or scented sprays, with extractor fans and window opening advised.
Wood and coal burning can also affect neighbors. Freedom of Information data cited by Mums for Lungs indicate that local councils receive approximately 15,000 complaints annually related to fires in neighbors' homes, underlining the wider impact of indoor burning on community air quality.
