Air Quality Data Suggests that for Some Bay Area Residents It's Not Safe to Inhale

By Hallie Gardner
Special to the Neighborhood Newswire

Data recently released by the Bay Area Air Quality Management District (BAAQMD) reaffirms what many low-income Bay Area residents have observed first hand:  growing up poor means that you’re far more likely to be raised in an unhealthy environment.  Toxic air contaminants, which pose a number of severe health ramifications, have high concentrations in the region’s low-income communities. 
According to BAAQMD, air toxins which cause the most adverse health impacts are concentrated near heavy industrial activity, freeways and airports – the same neighborhoods in which low-income communities tend to be located.  Diesel particulate matter, largely from heavy duty trucks and construction equipment, accounts for 80 percent of the elevated cancer risk associated with airborne toxins in the Bay Area.  The largest contributor to non-cancer related health risks is acrolein, a chemical produced by fossil fuel combustion from automobiles and airplanes.
A wide array of health problems have been linked to exposure to these air toxins, including lung cancer, asthma, premature birth, infant mortality and increased cardiovascular hospitalizations.  Children and the elderly are the most susceptible to air pollution’s effects. 
Many of the conditions that BAAQMD identified as being conducive to serious health problems are concentrated in Bayview-Hunters Point – as well as the adjacent Dogpatch and Potrero Hill neighborhoods – a predominantly low-income and minority neighborhood located in the southeast corner of San Francisco.  Bayview-Hunters Point, Dogpatch and Potrero Hill have been burdened with an abundance of air pollution sources, including San Francisco’s largest wastewater treatment facility, federal and state Superfund sites, a major power plant, hazardous waste storage facilities and hundreds of toxic sites.  The communities are also transected by two major freeways: 101 and 280.


Bayview-Hunters Point has the highest rate of asthma-related hospitalizations in San Francisco, with one in six children in the community suffering from the disease.  Residents’ hospitalization rates for emphysema, congestive heart failure and hypertension are three times the statewide average.  And infant mortality rates are the highest in California
Marie Harrison, a long-time Bayview-Hunters Point resident, has two grandsons who have been chronically ill as a result of respiratory ailments.  “Sometimes my grandson would come home from school and could barely breathe,” Harrison said.  After numerous nights at the hospital for her grandsons’ asthma attacks and mornings changing nosebleed-soaked pillows, she noticed that she wasn’t alone.  Many of her neighbors were suffering from serious respiratory ailments too. 
Harrison believes that poor air quality in Bayview-Hunters Point is an example of environmental racism.  She has found that many City officials are condescending about the illnesses residents face, often pushing the problem back on them, as if it were a result of residents’ personal decisions.  “San Francisco is a racist city,” said Harrison.  “What makes it that way is that people don’t recognize it within themselves.  People here think that they wouldn’t dare be prejudiced against any group of people.  But when I attend these meetings and bring up the problems we are facing I always hear, ‘Well, that’s their problem, that’s on their side of town.’”
BAAQMD is taking steps to address localized air quality problems.  In 2004 the District established the Community Air Risk Evaluation (CARE) program, the goal of which is to identify Bay Area communities that are subject to high levels of toxic air emissions.  The first program phase, which was completed in October, was to develop a preliminary emissions inventory of toxic air contaminants, as well as demographic and health data.  Over the next three years BAAQMD will work to further refine this information and use it as the basis to develop policies to reduce toxic air contaminant emissions in areas with high exposures and sensitive populations.
James Fine, a professor of environmental science at the University of San Francisco, believes that BAAQMD is moving in the right direction.  “This is a very ambitious and admirable effort that they’re undertaking, because what it’s doing is assessing the emissions burden with regards to toxic air contaminants at the community scale.  And this presumably will give them the technical evidence they need to focus emissions reduction programs on the communities where the emissions burden is greatest.” 
Despite the adversity she’s faced, Harrison remains optimistic about the City’s future.  “I still think San Franciscans are the most beautiful, progressive people in the world.  Because once you talk to people here and they acknowledge that these problems exist, they become powerful forces for change.
