Understanding Public Views about Air Quality and Air Pollution Sources in the San Joaquin Valley, California

ABSTRACT

The San Joaquin Valley of California has poor air quality and high rates of asthma. Surveys were collected from 744 residents of the San Joaquin Valley from November 2014 to January 2015 to examine the public's views about air quality. The results of this study suggest that participants exposed to high PM2.5 (particulate matter less than 2.5 microns in size) concentrations perceived air pollution to be of the worst quality. Air quality in the San Joaquin Valley was primarily perceived as either moderate or unhealthy for sensitive groups. Females perceived air pollution to be of worse quality compared to males. Participants perceived unemployment, crime, and obesity to be the top three most serious community problems in the San Joaquin Valley. Participants viewed cars and trucks, windblown dust, and factories as the principle contributors to air pollution in the area. There is a need to continue studying public perceptions of air quality in the San Joaquin Valley with a more robust survey with more participants over several years and seasons.

No MeSH data available.


Air quality (PM2.5) in 6 locations (Modesto: Mo, Merced: Me, Madera: Ma, Fresno: Fr, Visalia: Vi, and Bakersfield: Ba) in the San Joaquin Valley from September 2014 to January 2015 ordered north to south. The survey was conducted November 2014–January 2015. Not all locations where the subjects resided are included in this figure. This is included to give the reader a view of air quality experienced by residents. The air in the SJV decreases in quality as you move south.

Mentions: The participant demographics as well as outdoor air pollution exposure levels (PM2.5 level: high, medium, or low) are presented in Table 1. The majority of the participants (63%) were female. Close to half of the participants (51%) were over 40 years old. The general overall pattern is that PM2.5 concentrations, during the implementation of the survey, decrease as one moves south in the San Joaquin Valley (Figure 2). Only small percentage (7%) of our sample experienced low PM2.5 concentrations. The majority of our participants were exposed to medium levels (75%) and high levels (19%). The participants surveyed in Merced and Modesto experienced medium and low air pollution levels only. Very few (2%) of participants who responded via Internet experienced low air pollution levels and the majority (59%) experienced high air pollution exposure.
