Automotive/Transportation
I personally have to use a wheelchair to get around. While that is fine in and around the apartment I live in but can become very arduous when traveling 8 or 10 blocks or more. Note that I am 69 years old.
Have you ever noticed how dirty the front wheels of vehicles are? Do you know why? Brake dust!
The wear of brake pads and disks is a ubiquitous source of secondary emissions in all urban centers around the world!
