Using Indoor Air Filters Near Busy Highways Can Reduce Blood Pressure

The big idea For people living near busy highways, using air filters indoors results in short-term improvements to blood pressure, according to a new study I co-authored. Busy highways are large sources of air pollution. Larry D. Moore via Wikimedia Commons, CC BY-SA Next to busy highways and major roadways, there are high concentrations of air pollution – including exceptionally tiny, invisible and odorless ultrafine particles from burning fuel. My colleagues Neelakshi Hudda, Misha Eliasziw and I tested how using air filters indoors near a highway can reduce exposure to ultrafine and other particulate pollutants – and what effect that has on blood pressure. Our team tested 77 participants over three two-hour sessions in a room next to a busy highway. We manipulated the level of air pollu...

Ultraviolet light can make indoor spaces safer during the pandemic – if it’s used the right way

Ultraviolet light has a long history as a disinfectant and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight the spread of the virus and protect human health as people work, study, and shop indoors. The virus spreads in several ways.

But Washington was part of a dedicated group of community members who took matters into their own hands and improved what were long accepted conditions. She was enthusiastic about continuing that work, b...
