The SacMetro AQMD is responsible for cleaning the air to meet state and federal health standards so we all breathe easier. The area's two biggest air pollutants are ground-level ozone and particulate matter 2.5. In Sacramento County, the majority of air pollution during the summer comes from mobile sources, which are the cars, trucks, buses, agriculture and construction equipment that are used every day. In the wintertime, the majority of air pollution comes from wood burning in residential fireplaces and wood stoves. Together we work to improve the health and quality of life for residents.

Many of us experience some kind of air pollution symptoms such as watery eyes, coughing or wheezing. Even for healthy people, polluted air can cause respiratory irritation or breathing difficulties during exercise or outdoor activities. An individual's actual risk depends on their current health status, the pollutant type and concentration, and the length of exposure to the polluted air.
People most susceptible to severe health problems are:
Ground-level ozone reaches its highest level during the afternoon and early evening hours. High levels occur most often during the summer months. It's a strong irritant that can cause constriction of the airways, forcing the respiratory system to work harder in order to provide oxygen. It can also cause other health problems:
Particulate matter is a complex mixture that may contain soot, smoke, metals, nitrates, sulfates, dust, water and tire rubber. It can be directly emitted, as in smoke from a fire, or it can form in the atmosphere from reactions of gases such as nitrogen oxides. The size of the particles is directly linked to their potential for causing health problems. Small particles, known as PM2.5, pose the greatest threat because they can get deep into the lungs and even enter the bloodstream affecting both the heart and lungs:
Many environmental risks have been made worse by climate change based on scientific studies, including flooding, drought and wildfires. The SacMetro AQMD works with the community to reduce those impacts in the Sacramento region.
