The Environment Arizona Research & Policy Center released a new report showing the health risks posed by air pollution across the state.
In Tucson, people experienced 86 unhealthy air pollution days in 2015.
Unhealthy air pollution days increase the risk of premature death and asthma attacks.
Pima County officials issued several air quality advisories in June because the smoke from the wildfires blew into Tucson.
Congress introduced legislation to roll back federal Clean Car Standards which would result in 350 million barrels of additional oil being burned, 155 million metric tons of global warming pollution, and an additional $34 billion in fuel costs for Americans.
The center says this would lead to 3,600 additional premature deaths, 90,000 more asthma attacks in children, and 300,000 more missed work and school days by 2030.
Environment Arizona gathered more than 100 petition signatures, 800 photos from constituents, and a letter signed by 90 Arizona businesses in support of Clean Car Standards.
They delivered the messages to Senator John McCain's office in Tucson.
