    Hong et al. (2016) investigated the mechanisms behind how particulate matter, which contains chemicals such as polycyclic aromatic hydrocarbons (PAHs), causes rhinitis. This was an in vitro experiment, but they found that in cells exposed to particulate matter, reactive oxygen species were increased, while superoxide dismutase, catalase, and glutathioneperoxidase were decreased. When the cells were…
