Answer Wiki. It turns out that sulfur hexafluoride, SF6, is the most potent greenhouse gas ever measured. Greenhouse gas potency is measured with an unit called the GWP or global warming potential, and it takes in account the molecule's ability to absorb infrared radiation and survival in the atmosphere. SF6 is an octahedral molecule, with six S-F bonds, each capable of absorbing infrared radiation very well.
The most harmful of the gases and pollutants that emitted are particulate matter, carbon dioxide, polycyclic organic matter, and formaldehyde. (b) On plants. Photochemical smog has a deleterious effect on plants. Chronic exposure to ozone may weaken plants and make them susceptible to disease and reduce crop yield.
