State of the Air

The American Lung Association's 2017 "State of the Air" report found 7 out of 8 reporting counties have earned overall failing grades for ozone, one of the most common forms of hazardous air pollution.

California's soaring population, weather and topography are all factors that contribute to its air pollution, in a state where many people commute and live in valleys and basins where pollution tends to settle.

Janice Nolen, the lead author of the ALA report, told Business Insider that local problems like auto traffic can make cities' ozone or particle problems worse, but that the overall issue is a national one.

You look at some very local air pollution sources - for example the bridge crossings, we know have very high levels of air pollution. Salinas landed a spot on two lists of the cleanest cities in the US thanks to zero unhealthy ozone days and one of the lowest year-round particle pollution levels.

That was despite the fact that Hartford County's weighted average number of high ozone days ticked down in the 2013-2015 period compared to the 2012-2014 period.

The American Lung Association report revealed approximately 125 million Americans across the country or 40 percent of the nationwide population, are now living amid unhealthy air pollution levels, National Geographic reports.

When it comes to federal health guidelines, Barrett says annual particle pollution should be below 12.0 micrograms per cubic meter of monitored air.

Days with excessive ozone, which can trigger asthma attacks and worsen other lung problems, were down over past year.

Almost four in 10 Americans now live in counties that have unhealthful levels of ozone, particle pollution or both.

National findings saw improvement in ozone levels and year-round levels of fine particle pollution, but also saw a continued trend of extreme short-term spikes in particle pollution. "These leaders must support steps to improve the air we breathe so that it does not cause or worsen lung disease".

Six of the 10 cities with the worst air pollution are in California, according to a new report.

Trump's budget proposal contains a 31 percent cut to the Environmental Protection Agency (EPA), including weakening and eliminating the Clean Air Act. The Lung Association takes complex information about air pollution and translates it into a simpler, easier to understand "report card" to help people better protect themselves and their families.

DEEP said 95% of the ozone pollution comes from outside the state of CT.

California cities top the list of those most polluted by short-term particle pollution, among them Bakersfield, Fresno, San Jose, and San Francisco. The American Lung Association says particle pollution can affect the lungs and bloodstream, leading to asthma and heart attacks, lung cancer and even premature death. (American Lung Association) Annual particle pollution, from polluters like coal-fired power plants or wildfires, in the Baltimore-Washington region continues to drop, according to American Lung Association figures released in its 2017 State of the Air report.
