Air pollution and respiratory health in Los Angeles

Air pollution and respiratory health in Los Angeles

Reduce air pollution from stationary and mobile sources; protect human health and welfare and promote improved respiratory health: these are the major goals of the city of Los Angeles.

Air pollutants such as particulate matter, ozone, nitrogen oxides, and toxic air contaminants contribute to poor air quality and lead to health impacts such as lung cancer, cardiovascular disease, asthma, and other respiratory illnesses.

Studies have found that children, the elderly, low-income communities of color, and those living adjacent to transportation infrastructure with high traffic volumes are disproportionately affected by air pollution. Analysis of exposure to air toxins in Los Angeles showed that residents suffer from cancer risk in excess of the goals of the Clean Air Act, and low-income people of color tend to live in the areas of the city with the highest risk.

This policy supports efforts to reduce vehicle use through implementation of smart growth mixed land use patterns, expanding public transit and active transportation modes; limiting truck idling in residential neighborhoods and working with residents and relevant public agencies on regulations and complaint processes.

Emissions may be reduced further by reducing congestion, supporting conversion to lowand zero-emission vehicles, and retrofitting existing structures to lower pollution from power plants, refineries, and commercial and industrial businesses.
