Despite controls implemented over the years to lower emissions of air pollutants, Lake Michigan communities near the shoreline still experience elevated ozone levels that exceed federal ozone standards set by the Clean Air Act. Contaminants such as nitrogen oxides and volatile organic compounds interact with sunlight and hot temperature to form ozone.
To help these communities and other states near bodies of water with similar air quality challenges, EPA scientists are collaborating with multiple agencies for the Lake Michigan Ozone Study–a field study aimed at better understanding ozone chemistry and meteorology along the Wisconsin-Illinois Lake Michigan shoreline using a combination of aircraft, ground-based, and ship-based measurements.

The Trump administration says the current Environmental Protection Agency (EPA) standard for nitrogen dioxide pollution concentrations should stay in place.
The agency said it has completed a scientific review of the nitrogen dioxide standard from 2010 and determined that it is sufficiently protective of public health.

Concerned about what they saw as deficiencies in official monitoring, German citizen scientists developed a tool for measuring airborne particulates that anyone can build.

The EPA Sustainable and Healthy Communities (SHC) Seminar Series presents the Tribal Science Webinar Series, co-hosted by the National Center for Environmental Research (NCER) and the Office of Science Policy (OSP). The webinar series provides a forum for discussion of the complex environmental issues facing many tribal and indigenous communities, and features a wide variety of expert guest speakers from government, academic institutions and other organizations. This month’s webinar focuses on air pollution monitoring research collaborations with Native American and Hawaiian Native Partners. Presenters will discuss the development and nature of their partnerships, current research activities, and strategies for community engagement. These grants were funded by the Science to Achieve Results (STAR) 2014 Request for Application (RFA) on Air Pollution Monitoring for Communities.

A new study of 60 million Americans — about 97 percent of people age 65 and older in the United States — shows that long-term exposure to airborne fine particulate matter (PM2.5) and ozone increases the risk of premature death, even when that exposure is at levels below the National Ambient Air Quality Standards.

If you stand next to an experimental Google StreetView car in Oakland, you’ll hear whirring. On top of the vehicle–below the usual cameras taking photos of the street–a mechanical system with pumps is pulling in the outdoor air, feeding it through a set of tubes to air-pollution monitoring equipment in the trunk, and then pumping the exhaust back outside again.
The car is one of two from Google Earth Outreach that Aclima, a San Francisco-based company, equipped with a mobile air-quality platform. Over the last year–as each car drove six to eight hours a day around Oakland, repeatedly sampling every street in one section of the city–researchers collected the largest-ever set of urban air pollution data, and studied how the system could be used to better understand city air quality. The project was convened by the nonprofit EDF.
