Camden Household Air Monitoring Project

This study will observe the scale of indoor air pollution in homes throughout Camden and examine possible strategies to reduce exposure and improve the health and well-being of Camden residents

The adverse impacts of (outdoor) air pollution have received substantial academic and policy attention over the last few decades. However, indoor air pollution is often overlooked in academic research and policy discussions. This is somewhat surprising given that the western population spends approximately 90 percent of their time indoors and that indoor concentrations can often be much higher than outdoors. 

Through a partnership between Camden Council, the London School of Economics (LSE), and the University of Southern California, this study will observe the scale of indoor air pollution in homes throughout Camden and examine possible strategies to reduce exposure and improve the health and wellbeing of Camden residents. 

We are looking for Camden residents to take part in this project. The project will take place over a four-week period in which you will be given a small device to monitor the levels of air pollution in your home. It is very straightforward and quick to place the monitor in your home and we will provide technical support if needed. 

If you have received a letter from Camden Council asking you to participate in this study, please click here to register your interest and complete a short survey.

Why take part and what will you get out of it?

  • We will provide you with a report of the levels of pollution within your home throughout the duration of the study and information on ways to lower such pollution in the future. 
  • You will be involved in the production of scientific knowledge and will contribute to our understanding of air pollution in London and its implications for policy makers. 
  • You will be rewarded with a guaranteed £20 Amazon voucher
