Acute effects of particulate matter on respiratory diseases, symptoms and functions:: epidemiological results of the Austrian Project on Health Effects of Particulate Matter (AUPHEP)
M. Neuberger,Michael G. Schimek,Friedrich Horak,Hanns Moshammer,Michael Kundi,Thomas Frischer,Boštjan Gomišček,H. Puxbaum,H. Hauck +8 more
TL;DR: Time series studies applying semiparametric generalized additive models showed significant increases of respiratory hospital admissions at age 65 and older and in repeated oscillometric measurements of respiratory resistance in 164 healthy elementary school children not only immediate responses to fine particulate matter but also latent ones, possibly indicating inflammatory changes in airways.

Lean Burn Natural Gas Operation vs. Stoichiometric Operation with EGR and a Three Way Catalyst
TL;DR: In this article, the authors compared lean burn operation with operation at stoichiometric conditions diluted with EGR, and using a three-way catalyst, and showed that the results showed that NOdx and HC emissions were several orders of magnitude lower than at lean operation.
