Scientists track super-small pollutants that are inhaled into the brain

Brown clouds made up of noxious gases, dust, soot and even finer particles hang over buildings and hug the ground of polluted cities. When people are outside they can’t help but breathe in. In Mexico City there is air pollutants that can hurt your lungs but, can also damage the brain. This kind of air pollutant can lead to serious health problems like gasping and wheezing. The contaminated air goes to the respiratory tract that helps supply air to the lungs. Also, nanoparticles can sneak into the lungs and can enter the bloodstream. From there, these materials travel throughout the body. Some share of them will end up polluting the brain.
