Electric school buses are a breath of fresh air for children | Nearly $1B in federal funding could help clean up the unequal health impacts of diesel pollution.::Nearly $1B in federal funding will help decarbonize transportation and clean up some of the unequal health impacts of diesel pollution
Enough to be harmful. Humans get exposed to dangerous things every single day, even if you don’t leave the house, it’s just in a quantity to not effect you during a human lifespan.
And you know it is not enough to affect children how? Have you done a study? Because the National Institute of Health here in the U.S. did.
It’s 2 decades old so I hope the US has gotten better busses in the meantime because modern busses don’t have this issue:
“The study showed that a child riding inside a diesel school bus may be exposed to as much as 4 times the level of diesel exhaust as someone riding in a car ahead of it.”
The level of harm in that study was around 30 potential extra cases of cancer per million kids, that is fairly low considering the harm added by just general exhaust fumes for those living near busy roads. Even the study itself shows that living near a road frequented by trucks is more harmful.
So my suggestion of just get public transit would be better remains mostly resolute, I would just add that use trains for cargo and not trucks.
