Air Quality

Outdoor air pollution, in the most extreme cases, can be immediately identified even without any special training. It casts a haze over cities, collects on streets and buildings, and provides dramatic fodder for the news. But while high drama is often a prerequisite for news about air quality to be reported, the real story is the health impacts that occur even when the air isn't thick enough to see.

According to the EPA, Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations. Most pollutants affecting indoor air quality come from sources inside buildings, although some originate outdoors. Typical pollutants of concern include combustion products such as carbon monoxide, particulate matter, and environmental tobacco smoke; substances of natural origin such as radon; biological agents such as molds; pesticides; lead; asbestos; ozone (from some air cleaners); and various volatile organic compounds from a variety of products and materials

This is even more striking when the health effects attributed to outdoor fine particulate matter (PM2.5) rank among the risk factors with the highest health impacts in the world, annually accounting for over 3.2 million premature deaths. In October 2013, the World Health Organization announced they are considering particulate matter, a major component of indoor and outdoor air pollution, as a Group 1 carcinogen along with tobacco smoke and asbestos.

Welcome to the PLOTS Air Quality Google Group

This is the link to the Public Laboratory mailing list devoted to air quality research and discussion. Several projects use this list, including hydrogen sulfide sensing near fracking sites, "DustDuino" by Matt Schroyer and Willie Shubert, the "balloon board" modification to Air Quality Egg that serves as an air column monitor, and others. In the past, this list served the Cypress Hills Air Quality (CHAQ) initiative. Now it hosts a wide variety of projects, so jump in!

Cypress Hills Air Quality (CHAQ) Initiative

This 8 week Air Quality Class was created for the Cypress Hills Air Quality (CHAQ) Initiative, with support from the United States Environmental Protection Agency's program "Citizen Science: Community Involvement Today and in the Future". This project was a collaboration with the Cypress Hills Local Development Corporation. Joe Saavedra and Liz Barry are the Public Laboratory facilitators. Georgia Bullen, Yael, and Jason Lipshin are involved from MIT.
