Oh, CO2 is toxic at the cellular level although generally death is caused by asphyxiation rather than "poisoning". There is some research that suggests that long term exposure to high levels (3-10%) of CO2 causes long term damage to the cells in the lungs, for example, although this was from animal studies not specifically humans.Andres125sx wrote: ↑02 Jul 2021, 08:01
Second because ICE emit a lot of toxic substances wich are harmful for humans and any living organism (CO2 is not toxic)
But agreed that for CO2 coming from cars, it's not really an issue unless sat in a closed garage with the engine running.
