A study conducted in Wales has revealed that the primary source of daily pollution exposure for children is not from outdoor activities but rather from their home environments.
Significant Pollution Levels in Homes with Wood Burners
Children residing in homes equipped with wood burners are subjected to more than three times the air pollution compared to those living in homes without wood burners. This finding is based on a study targeting air pollution exposure among primary school children in Wales.
Researchers equipped fifty-three children from two primary schools in Anglesey with backpacks carrying air pollution sensors. These children carried the backpacks to and from school and kept them at home, enabling the collection of continuous pollution data.
Dr. Hanbin Zhang of the University of Exeter, a member of the research team, highlighted that the main source of particle pollution exposure in children was their home environments, surpassing exposure levels at school and during commutes. He noted that indoor activities such as wood burning and indoor smoking were significant contributors to this pollution.
Short-term spikes in pollution levels were often linked to cooking and exposure to secondhand tobacco smoke at home. The use of stoves or fires for heating contributed to more prolonged pollution exposure, often lingering overnight in the children’s bedrooms due to ongoing burning or smoldering combined with poor ventilation.
Prof. Zhiwen Luo of Cardiff University, who led the study, pointed out that in homes with wood burners but no tobacco smoke, the average particle pollution level reached about 13 micrograms per cubic meter. This is considerably higher compared to just 3.5 micrograms per cubic meter in similar homes without wood burners.
Although the study was relatively small, the consistent results across different homes underscore the significant impact of wood burning on increasing indoor pollution levels.
Rural Versus Urban Pollution Exposure
The research also compared pollution exposure between children in urban and rural settings. Interestingly, children in urban areas experienced lower levels of particle pollution than those attending a rural school. The study, conducted during winter, attributed these differences to varying rates of wood burning, which was more prevalent in rural homes.
Additional studies, including recent research in New Zealand and an earlier study of 50,000 US women, have linked wood burning at home to health risks such as increased asthma incidences and lung cancer, respectively. The US study highlighted a significant 43% increased lung cancer risk among women who used wood stoves or fireplaces, with this risk evident among both smokers and non-smokers.
Engagement and Insights from Children
Engagement with children was a crucial component of the Anglesey study. Dr. Shuangyu Wei of Cardiff University noted that helping children understand their personal exposure data led to increased awareness and discussions about indoor pollution sources, sometimes prompting behavioral changes. Schools reported that parents began to discuss the findings and explore potential sources of indoor pollution based on the study’s data.
Cooking activities were identified as additional contributors to measured air pollution, particularly when backpacks were left near kitchens. Brief spikes in pollution were also recorded when children passed by bakeries and restaurants.
Interestingly, the study found that pollution levels inside the schools were much lower than those recorded during travel or at home. Additionally, children who walked to school were exposed to less pollution compared to those who were driven, especially when parents smoked during the drive, which resulted in the highest pollution levels measured in the study.
The UK government is currently considering health warnings for new stoves and solid fuels to address these concerns.
