Measuring air pollution
along Columbus Avenue and other projects in SF

Street Air was founded by three San Francisco students who are interested in science and engineering.

Our first project examined how bus, truck, motorcycle, and car traffic affected air pollution levels near outdoor eating areas on Columbus Avenue. After finding there were air impacts at outdoor eating places, we concluded the study with ideas of how to reduce air pollution near street-edge cafes and restaurants.

​We are currently expanding our air pollution research to include new areas of interest, such as measuring particulate matter (PM 1 and PM 2.5) levels in underground transit facilities. We are also engaged in multiple-exposure studies where we measure both noise and particulate matter levels at locations throughout San Francisco.  Finally, we are monitoring a cement batching plant in Bayview to determine the plants effect on air pollution levels in the Bayview community.

Our motto: "Every problem deserves a solution."

​News
Google Street View Air Pollution Data  is being evaluated by Street Air 

Google recently authorized Street Air to view and evaluate its Street View air pollution data. Street Air is identifying PM 1, PM 2.5 and NOx hot spots for further research and study. Street Air’s goal is to identify the reason for the hot spot; identify possible mitigations, and; quantify the hot spot boundaries. See    http://streetair.org/maps-and-data.html

The Green Screen
The Green Screen is a new Street Air program that identifies neighborhood environmental issues, then brings the issue to the public's attention through the use of film. We call it a persistent film festival as the site will add new content as it is created. Neighborhoods can't wait a year or more for a film festival to show a film about a particular cause or issue because neighborhood health issues need to be brought to the public's immediate attention. This "film festival" will be always open and available for viewing. We welcome interested person's  to join us and and submit their films for use in this  this project: www.thegreenscreen.org.

 STREET AIR  receives "Outstanding Achievement" award from the United States Environmental Protection Agency.   On April 9, 2019  The US Environmental Protection Agency awarded  Zelda Zivny, Charlie Millenbah and Milo Wetherall   "Outstanding Achievement" awards as a part of the agency's Presidential Environmental Youth Awards program. The award was for   founding Street Air and completing Street Air's Airgregates  project and other long-term environmental science projects.

"Airgregates"   New Film Released by STREET AIR
Street Air completes its newest film, "Airgregates",   about the effects of  Pier 92 concrete mixing plants on the Bayview Community. November 11, 2018.   See film here:   https://youtu.be/yqCoSgbyhyw        A note on   dispersal   of particulates at this concrete   mixing site;   We have found that wind direction changes to the east at night and in the early mornings,  as well as during the winter months. The facility is often open on weekends, night and very early mornings. Local residents have reported sand on their cars in the morning or that they have to close their windows at night. The film was recently awarded "Finalist" in the 2019 Clear the Air Film Festival in San Francisco.

Los Angeles has found that siting apartments near freeways has caused problems for residents due to the diurnal shifts in wind direction and patterns. The LA studies have also found that particulates travel much further at night than during the day. "Postpone outdoor exercise to later in the morning to dodge the spike in traffic pollution in the pre-sunrise hours. That’s when stagnant weather conditions, caused by nighttime cooling, trap freeway pollution near the ground. That slows down the dispersal of emissions, allowing them to drift more than a mile downwind, compared to no more than 1,000 feet during the day".   Source:

Air Pollution Linked to Neurological Disorders
Air pollution was significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementias, in a long-term study of more than 63 million older U.S. adults, led by researchers at Harvard T.H. Chan School of Public Health.

The study, conducted with colleagues at Emory University’s Rollins School of Public Health and Columbia University’s Mailman School of Public Health, is the first nationwide analysis of the link between fine particulate (PM2.5) pollution and neurodegenerative diseases in the U.S. The researchers leveraged an unparalleled amount of data compared to any previous study of air pollution and neurological disorders.

The study was published  by   The Lancet Planetary Health, online October 19, 2020,   https://doi.org/10.1016/S2542-5196(20)30227-8

Massive  study reported by The Lancet shows that PM 2.5 causes diabetes.   "Interpretation: The global toll of diabetes attributable to PM2·5    air pollution is significant. Reduction in exposure will yield substantial health benefits". The study is titled, "The 2016 global and national burden of diabetes mellitus attributable to PM2·5  air pollution" and can  be found here:

Air Pollution Might be the New Lead. Research   on the effects of air pollution on cognitive function is getting more sophisticated.  Recent studies have shown that the long term effects of air pollution  on human brain development may be significant.   Read the Popular Science article here.:     https://www.popsci.com/air-pollution-lead-poisoning-brain-development

​STREET AIR receives   new custom   PM1 monitors from Dylos.  (4/12/18).    http://streetair.org/pm-1-research.html​

STREET AIR begins PM 1 study along Columbus   Ave. and in nearby restaurants on January  2018. The PM 1 study will be enlarged to   other areas of San Francisco    as PM 1 data is generally  missing in urban pollution data (especially specific location data).  Additionally, the Journal of the American Medical Association has recently published data on how certain levels of  PM 1  concentrations can cause premature births, and;  ".... findings suggest that most of the emergency hospital visits attributed to PM2·5 are due to PM1."                    http://streetair.org/pm-1-research.html​

​ABOUT STREET AIR
​
Zelda Zivny, Charlie Millenbah and Milo Wetherall,   who are her North Beach neighbors and schoolmates,   were walking along Columbus Ave and noticed a large increase in vehicle traffic along the street, especially commercial traffic. We also noticed a new city parklet that put eating places further into the street and closer to the traffic. “Is this safe”? “Is this a good place to eat”? We wondered.  The three of us decided to study Columbus Avenue's  design and also to take pollution measurements along the street where people walk, ride their bikes, and where they eat. We eventually called this project Street Air.   Now in its third year, we have expanded our inquiry and we are now interested in the effects of street-level air pollution on nearby restaurants and on the people who work there  ( http://streetair.org/particle-dispersal-study.html).

 We eventually won awards at the Clear the Air Film Festival (sponsored by the Bay Area Air Quality District and Breathe California) for our film "Columbus Discovers Air Pollution" that documented our early discovery of particulate pollution along Columbus Avenue. We won the "Best Film" award, and we were also awarded the "Audience Favorite" award for the entire festival. Based on the success of the film at the Clear the Air Film Festival, our group was invited to show  Zelda and Charlie's film "Climate Change" at the San Francisco Green Film Festival .   We were also selected to show our film "Columbus Discovers Air Pollution" at the San Francisco Urban Film Festival  at SPUR headquarters in downtown San Francisco. After this screening, our group  agreed to appear in a panel discussion with City of San Francisco planning staff to discuss our recommended design changes to the street and city 'parklets." (Please see the  "Project Description," "Recommendations," and the "Particle Dispersal  Study" pages on this web site for more information on  the project methodology and research results).  Note, we studied both 'parklets' and regular outdoor street-side eating areas for this study.

​ San Francisco Urban Film Festival      (City of San Francisco  Staff Present)
After our film was screened at SPUR headquarters in downtown San Francisco,  we  moved to the front of the theater to engage in a panel discussion and to answer audience questions. Besides the three of us, also present was  Robin Abad  Ocubillo, Urban Designer and Planner with the City Design Group of the City of San Francisco Planning Department. Mr. Ocubillo was involved with the first designs of the  city parklets including the Columbus Avenue parklet that we  monitored in our study of Columbus Ave.  The result of our screening and the panel conversations with Mr. Ocubillo was that the city was  working on making changes in  street design standards and  the city supported  the recommendations we made in the film. Mr. Ocubillo  StreetAir should get involved with the educating the community, and to work with city staff in developing a new design of  Columbus Avenue that  makes more room for pedestrians. City staff and the three of us believe that if local businesses and residents knew of the environmental health dangers  of  poorly designed outdoor eating places, that the community would then  be more open to reducing  street parking and  vehicle traffic on Columbus Ave (see the article on our process: https://www.newamerica.org/ca/blogs/film-catalyst-innovation-urban-planning/ ). 

As a group we are interested in environmental science and using science in an applied way. That is, we want to use science to find  solutions to local environmental policy issues and to develop urban designs that will help mitigate human exposure to street-edge air pollution. We are also interested in helping build a body of knowledge of local street-edge air pollution in terms of  what types of pollution  exist , in what quantities, and its composition. We are also interested in how this pollution disperses and how it impacts various  local  residents and people who engage in various activities along the street.
