About Air Pollution in the Community

Everyone deserves to breathe clean, healthy air, no matter where they live. In Los Angeles County nearly all of us live in areas that are affected by air pollution, with poor communities and people of color being most affected. Breathing polluted air can have serious health consequences, from eye irritation to asthma attacks and even premature death. Most pollutants in our air come from cars, trucks, and other vehicles, but air can also be contaminated by factories, other businesses, and even the furniture inside our homes. Air quality also worsens with climate change through hotter weather, drought, and wildfires. Federal and state laws are in place to protect the air we breathe. You can help protect the air in your community by reporting air-related problems to local agencies.
