This study is to measure your surrounding air pollution and air temperature level using a stationary air quality sensor and a temperature logger. Your data will be used to tell where and when the air you are breathing is healthy or not and how much heat you are suffering. Because the healthy/heat level of air changes from hour to hour and from street to street, and the air quality/temperature monitoring stations are not always close enough to measure our neighborhood, this research is aimed to give the answer on how to better monitor the air at the block level. The data collected from citizens will also provide valuable information to study how air pollution can affect our health. This study is funded by National Science Foundation and Lau Grant.
What do we measure?

PM2.5 are fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. It is harmful to our health as it gets deep into our lungs and some may even get into our bloodstream. Numerous scientific studies have linked particle pollution exposure to a variety of problems, including: premature death in people with heart or lung disease, asthma, increased respiratory symptoms. Here is an EPA article on PM2.5 facts.
Temperature is an informative indicator of heat. Extreme temperatures can set life-threatening heatwaves for citizens. As the top weather killer, excessive heat kills nearly twice as many populations than tornadoes and almost three times more populations than hurricanes in the US. Texans are no strangers to heat in the summertime and the temperatures are predicted to rise in the future.
Can I participate?
Can I participate?
We welcome all citizens! Your participation in this research study will involve installing an air quality sensor outside of your residential place for at least six months.
Any residence who
is an adult older than 18 who lives in Stockton and vicinity areas;
have access to power outside your residence and have a wifi connection.
will be in the same house for at least the next 6 months.
The participants will be given a free PurpleAir PA-II-SD air quality monitoring device and a HoBo temperature data logger. The participants will be asked to connect the PurpleAir device to their personal Wi-Fi connection and then attach the device outside of their home using zip ties or a crew and screwdriver and then plug the device into a power outlet. The device will collect data for at least 6 months. The research team will visit the residential place every month to collect data from the HoBo data logger via bluetooth .
Sites w/o power and wifi:
Sites w/o power and wifi:
We realize that many sites may not have power and wifi access but would be crucial in making the monitoring network more representative. To facilitate the deployment of sensors in those areas, we have a limited number of solar-powered boxes that use the cellular signal to transmit data. To ensure security, we prefer sites that are fenced or can be locked.
CONFIDENTIALITY
CONFIDENTIALITY
Efforts will be made by the research team to keep your personal information private, and disclosure will be limited to people who have a need to review this information. All paper and electronic data collected from this study will be stored in a password protected computer in PI’s campus office on the UCB campus and/or a secure UCB server. Research records will be labeled with a code and the master key linking names with codes will be maintained in a separate and secure location.
