Air quality, optimal health and community growth are major concerns for residents of Contra Costa County. Equally important is the fact that business and industry are vital to economic development and sustainability. However, from time to time, communities are adversely affected by industrialized companies. For example, in East County, asthma prevalence has risen above the state average. In fact, in the State of California, this upward trend of asthma prevalence has risen steadily since 2004. About 1 in 8 Californians report they have been diagnosed with asthma.

Air pollution has been linked to an increase in the exacerbation of asthmatics conditions which vary often require additional medical care including emergency room visits and hospitalizations. In addition, asthma complications incur medical and economic cost. Severe asthma conditions can be life-threatening.

According to the Center for Disease Control (CDC), long term exposure to particular matter in the air increased the risk of lung cancer even at levels lower than the government agency recommended limit values. Consequently, residents living near polluting industrial facilities have the greatest risk exposure; thereby resulting in a localized pattern of disease such as lung cancer. But the question remains: What’s the connection between air toxins from industrialized facilities in East County and asthma and lung cancer among residents of East County?

In order to answer the preceding question, a group of interns from Los Medanos Community Healthcare District and I undertook a descriptive epidemiology and methodological process. Our hopes were to identify the link between air pollutants from industrial facilities located near Pittsburg and Antioch, California and the increase in asthma exacerbations and lung cancer mortality among residents in East County. An extensive online search of journals, government reports, community health publications, public health data, empirical evidence from peer-reviewed studies and an onsite random sample survey and interviews were all researched, analyzed and evaluated to meet our litmus test.

A large amount of evidence clearly showed the link between an increased in the number of asthma hospitalization and medical emergency visits in Contra Costa County and the quantity and types of air pollutants emitted from industrial facilities located in or near Antioch or Pittsburg. In addition to the four known air toxins which trigger asthma exacerbations, we identified four known carcinogenic air toxins which have been known to cause lung cancer. In fact, five industrial chemical facilities located near Pittsburg, California have a long history (since 2002) of releasing large quantities of these toxins.

During our random sampling and on-site interviews, we found that 82 percent of respondents reported that they have someone in their household who has a breathing problem. Moreover, 57 percent believe that industrial facilities are the greatest contributor to air pollution. An overwhelming 86 percent were very concerned about the health consequences of poor air quality.

In regards to health disparity that exist among people of ethnic diversity and lower socioeconomic communities, it’s a matter of geographical locations. And, unfortunately, incidence, prevalence and mortality are all affected by geographic. Consequently, residents who reside in San Pablo, Pittsburg, Antioch and Oakley have a greater exposure rate and therefore are more susceptible to asthma exacerbations and incidence of lung cancer than any other cities in Contra Costa County. Of course, physical, pre-existing health, socio-economic and environmental determinants are important factors as well.

As the interns coined the theme of our research, “The Battle to Breathe”; I’m perplexed with the thought of residents in East County having to battle to breathe, meanwhile industrialized facilities battle for business. All in all, I hear the sound of a bitter sweet symphony.
