We typically spend 80% of our time indoors, where the quality of the air we breathe depends on the age and type of building we occupy, as well as indoor pollution and outdoor pollution sources.

The comprehensive research examined air quality in Reno, Nevada during 106 wildfires to illuminate the atmospheric and public health impacts of smoke.

Fragrances and lotions don't just change the way people smell, they actively alter the indoor air chemistry around the wearer, disrupting a critical natural process the body uses to protect itself from pollution, according to an international research team that includes scientists from Penn State.

The 120-mile Tijuana River flows from Baja California into the United States and discharges millions of gallons of wastewater — including sewage, industrial waste and runoff — into the Pacific Ocean every day, making it the dominant source of coastal pollution in the region.

While concentrations of older “forever” chemicals appear to have decreased in many foods over the last two decades, a new study found that drinking water, along with seafood, eggs, and brown rice, still contribute to PFAS exposure in adults. 

Global warming is already very tough for animals in the wild, but it may be toughest for creatures like fish, whose body temperatures are controlled by the water temperatures around them.
