Air Pollution and Health in Southall, London
March 2020
With special thanks to Angela Fonso & Jo Griffin.
Before reading this report please note that we are a non-profit grant and citizen supported lab, we use our funding to create free scientific reports, which provide foundational knowledge about health, health inequities, and health justice. We prioritise the hiring of scientists and researchers from marginalised communities to ensure that the lived experience is covered in an ethical, inclusive, and accurate manner.
Our goal is to be an open lab that is “for the people by the people” and your support helps make that happen.
Centric Lab has done a three month study on the phenomena of the Southall community. We were instructed pro-bono to investigate if Southall Waterside, a real estate development led by St. Williams Homes LLP, had a role to play in the self reported spikes in health issues in the residents near the site.
Public Health England (PHE) has reported that the site poses no health risk to the community at Southall due to air pollution levels being below the recommended guidelines and dissipation rate of the air pollutants. However, Centric Lab is putting forward a new perspective, which takes into consideration the biological make-up and susceptibility of the Southall community. Not every community has the same level of susceptibility to air pollution. This is due to each community’s unique physical and psychosocial stressor exposures. Physical stressors refer to tangible external stimuli e.g. chemical/biological agents, while psychosocial stressors refer to external demands that exceed an individual's perceived abilities and resources to adequately respond.
In the following report, we put gathering evidence to highlight the susceptibility of the Southall community and the need for stricter air pollution guidelines. Our research will explain why in our analysis the air pollution guidelines used by Public Health England (PHE) to advise the Southall Waterside development did not take into consideration the susceptibility of the Southall community. In turn, these guidelines could still cause a health risk despite abiding by World Health Organisation (WHO) air quality suggestions. Additionally, we will delineate how using population level data like the ones used by PHE is not granular enough to give a reliable health risk indication. This would mean the Southall Waterside development consortium will need to take stricter measures as the current levels of air pollution are a health risk, especially as clean air should always be a priority.
Finally, we will also suggest PHE to conduct a more rigorous cross-sectional study to understand how the air pollution from the site is affecting the health of Southall at an individual level.
