The team then bred the mice and checked their offspring for DNA mutations.The mice born to males that breathed unfiltered
air had up to 2.8 times more mutations in
particular stretches of noncoding DNA than did mice with fathers that breathed
filtered air, or clean
air at a rural site.
As far as I can tell, the
filters — manufactured by MANN+HUMMEL — don't exactly capture all the brake dust and tires from one
particular vehicle, but rather they
filter air as the vehicle drives along, and are designed to
filter as much particulate matter as the vehicle itself is likely to produce.
