Yes, pollution is bad for health. It's bad for the lungs, it could cause cancer and may be associated with cardiovascular disease. How about a child's brain?
This study, conducted by researchers from the University of Montana compared serum and spinal fluid from children living in Mexico City to those living in a low-pollution city. They found that kids living in Mexico city had higher levels of autoantibodies that could contribute to neuroinflammation and ultimately to disease such as Alzheimer's or Parkinson's.
