Los residentes del Valle de San Joaquin respiran el aire MÁS PELIGROSO del País

The San Joaquin Valley faces severe air quality issues, with Bakersfield and Merced identified as the most ozone-polluted cities in the US in 2003. The region failed to meet federal health standards for fine particulate matter by 2004, with agriculture and heavy transport identified as primary emission sources.

• In 2003, the EPA identified Bakersfield (a medium-sized city) and Merced (a small city) as the most ozone-polluted cities in the United States.
• By 2004, the entire San Joaquin Valley failed to meet federal health standards for fine particulate matter, a type of pollution linked to pulmonary and cardiac diseases and deaths.
• Agricultural operations and heavy-duty vehicles (trucks and buses) are the primary sources of ozone precursor emissions and direct particulate matter emissions in the region.
