Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities.

When ozone forms air pollution, it's also called smog. Some air pollutants are poisonous. Interior department vows to amend methane rule after setback. This post originally appeared on Climate Central.

Interior department vows to amend methane rule after setback

The Department of Interior plans to try to roll back rules limiting methane pollution and waste from fossil fuel drilling on federal lands, after a bid to repeal the regulations failed in the Senate. Senators voted 51-49 Wednesday against an effort to repeal the Obama-era rules, with three Republicans joining all Senate Democrats in voting to oppose it. Methane is a major component of natural gas, and it’s also a health hazard and a major contributor to global warming. Some escapes from gas and oil operations to the atmosphere by venting or through leaks, and some is burned off in a process called flaring.

Sen. While Interior Secretary Ryan Zinke told Bloomberg he has “never been very comfortable” with the waste of natural gas from public land, his department said after the vote it had “flagged the Waste Prevention rule as one we will suspend, revise or rescind.” Beach season is over. Be glad yours didn't feature giant clouds of DDT. As summer comes to a close, let's take a moment to remember the DDT beach parties of the past.

Beach season is over. Be glad yours didn't feature giant clouds of DDT.

Who wouldn't want to end a long day of paddleball and boogie boarding by being submerged in a thick cloud of dichlorodiphenyltrichloroethane? The DDT beach bash was a surprisingly common feature of the early 20th century. In 1945, the New York Times reported glowingly on testing of the "insect-killing fog" at Jones Beach in Long Island. "Early arrivals among the 60,000 visitors at Jones Beach State Park here today found themselves suddenly enveloped in billowing clouds of sweetish smelling fumes," the paper reported.

Your Nail Polish Could Be Disrupting Your Hormone System

She said that she knew I worked in environmental health and wouldn’t want her to get her nails painted. I cringed but simultaneously rejoiced. I had officially become “that mom”—the one whose kid passed on nail polish because it might be toxic. I was especially relieved when I saw the latest report from the Environmental Working Group (EWG), the nonprofit research and advocacy organization where I am executive director. California Sees a 76 Percent Decline in Cancer Risks, Thanks to Cleaner Air - Plugged In - Scientific American Blog Network. Rules that regulate air pollution in California have led to a dramatic drop in cancer risks since 1990.

California Sees a 76 Percent Decline in Cancer Risks, Thanks to Cleaner Air - Plugged In - Scientific American Blog Network

According to a new study published in the journal “Environmental Science and Technology,” California saw a significant drop in seven major toxic air pollutants between 1990 and 2012. New EPA Rule Limiting Ground-Level Ozone Draws Fire From All Sides. A new rule from the Obama Administration aims to further reduce the main ingredient in smog.

New EPA Rule Limiting Ground-Level Ozone Draws Fire From All Sides

That might sound like good news if you live in a city where smog is a problem. But after the rule was announced, there were plenty of complaints about it. Technically, the Environmental Protection Agency is reducing the National Ambient Air Quality Standards (NAAQS) for ground-level ozone limits from the current level of 75 parts per billion (ppb) down to 70 ppb. Ground-level ozone is linked to respiratory illnesses and it can worsen diseases like emphysema and asthma. U.N. lists air pollution as carcinogen. If you want to avoid lung cancer, the United Nation’s cancer-research body has some advice for you: Don’t breathe.

U.N. lists air pollution as carcinogen

The International Agency for Research on Cancer on Thursday added air pollution, and the particulate matter that it contains, to its list of carcinogens. The airborne poisons were classified as “Group 1″ carcinogens, meaning there is “sufficient evidence” that they cause cancer in humans. They are mostly produced through the burning of fossil fuels in vehicles, power plants, and stoves. Fatal Birth Defects Possible, Court Blocked EPA Air Pollution Rule. God forbid we want our children to breathe clean air!

Fatal Birth Defects Possible, Court Blocked EPA Air Pollution Rule

I know a young woman whose mother worked at a plant that used mercury before its dreadful effects were recognized. When the woman’s baby was born, the infant was missing her left arm from the elbow down. Image what that would be like. Severe To Fatal Birth Defects. Today the Supreme Court struck down one of the Obama administration’s most important environmental regulations.

After a decade of struggling, this April the Environmental Protection Agency’s (EPA) first-ever limits on mercury and other toxins started to take effect. The Supreme Court Just Delivered A Victory To Coal Plants That Want To Emit Unlimited Mercury. Power plants may continue to be able to emit unlimited mercury, arsenic, and other pollutants thanks to the Supreme Court, which on Monday took steps toward invalidating the first-ever U.S. regulations to limit toxic heavy metal pollution from coal and oil-fired plants.

The Supreme Court Just Delivered A Victory To Coal Plants That Want To Emit Unlimited Mercury

In a 5-4 ruling, the Supreme Court found fault with the Environmental Protection Agency’s Mercury and Air Toxic Standards, commonly referred to as MATS. The EPA had been trying to implement a rule that cut down on toxic mercury pollution for more than two decades. But the Supreme Court majority opinion, written by Justice Antonin Scalia, said the EPA acted unlawfully when it failed to consider how much the regulation would cost the power industry before deciding to craft the rule.

“EPA must consider cost — including cost of compliance — before deciding whether regulation is appropriate and necessary,” the opinion reads.
