What dense sensor networks can teach us about air pollution

Maria Harris is an Environmental Epidemiologist.

It all started with a challenge in 2013: how to engineer pollution-sensing balloons. Thomas Kirchstetter, Adjunct Professor at the University of California, Berkeley and the Director of the Energy Analysis and Environmental Impacts Division at Lawrence Berkeley National Lab, wanted to attach pollution sensors to high altitude weather balloons to measure how black carbon moves throughout the atmosphere.

Black carbon “soot” is emitted from diesel engines on trucks, locomotives, and ships, as well as from wildfires and the combustion of solid fuels for cooking and heating. But available technology to measure this air pollutant wasn’t well suited to handle the changes in temperature and humidity experienced during its ascent through the atmosphere or affordable enough to scale. So, he and Berkeley graduate students Danny Wilson and Julien Caubel researched what it would take to create their own.

Meanwhile, Kirchstetter had been in touch with Joshua Apte, assistant professor at the University of Texas at Austin, about his work leading Environmental Defense Fund’s mobile pollution monitoring study using Google Street View cars to measure air quality in Oakland. Apte asked Kirchstetter to support the team’s analysis as they examined how pollution concentrations varied from block to block—including black carbon. That’s when a lightbulb went off for Kirchstetter.

Sensors and electronic health records reveal block-by-block traffic air pollution health disparities among the elderly in Oakland

Dr. Ananya Roy is a Health Scientist

Many public heath efforts, thankfully, focus on the youngest among us. We fight for a clean environment and healthy future for our kids. However, it is easy to forget that pollution affects us in every stage of life and its insidious health effects accumulate over time and can result in disease and disability.

Older people already have higher rates of disease and are highly vulnerable to air pollution, because they have been breathing for 70, 80, or 90 years. The effects of air pollution among the elderly provide insights that help us solve problems that can benefit the whole population.

Senior citizens have become the largest and fastest-growing segment of the population. By 2030 one in five Americans will be 65 and older, a demographic shift that influences everything from consumer behavior to health-care costs. Further, grandparents play a critical role in the success of families and the next generation – both emotionally and physically. It is estimated that for approximately 4.9 million families with children, the grandparent is the main breadwinner.
