Scientists Have Detected Metal Pollution in the Human Brain

Detecting iron oxide particles in the human brain is apparently nothing new for scientists. Detecting iron oxide particles derived from traffic fumes in the human brain, however, is new—not to mention terrifying. Put simply, traffic fumes produced from cars may actually be polluting our brains. What's more, we may be breathing these harmful particles in through our noses when navigating foot traffic or even while driving our own cars. Having been linked to Alzheimer's disease, these magnetic particles are capable of inflicting serious damage on our nerve cells.

This unsettling news comes out of Lancaster University in the UK, as recently reported by New Scientist. Professor Barbara Maher and team looked specifically at the shape of these magnetic oxide particles found in the human brain, noticing that they are round in shape. This suggests that the particles are formed when fuel is burned, meaning they could be entering through the nerves in our noses when we inhale fumes. "These findings are sufficiently alarming for me to alter my behavior," Maher told New Scientist. "If I'm walking in a really busy street, I walk as far from the curbside as I can. The concentration of particulate matter drops even across the pavement's width."

Maher also recommends keeping a safe distance between your car and the car in front of you while driving, and to keep your air conditioning on recirculate. "Everybody deserves to have this information so they can take steps to reduce their own exposure level," she concludes. While Maher admits that these findings are in no way definitive, it's definitely worth bearing in mind when commuting to work or traveling on weekends.
