The Pima County Department of Environment Quality anticipates that the ground-level ozone air pollution will be high on Friday and Saturday.

The PDEQ anticipates that the ground-level ozone air pollution will also be high on Saturday, a news release said. Those who are especially sensitive to air pollution may experience shortness of breath, coughing, throat irritation, wheezing and breathing discomfort.

For those who are especially sensitive to ozone, the PDEQ advises to limit the level of exertion outside between noon and 6 p.m. when elevated levels of ozone pollution are more likely to occur. Intense physical outdoor activity causes faster and deeper breathing, allowing ozone to penetrate into the parts of the lungs that are more likely to be injured.

Declines in Air Pollution Have Made Hurricanes StrongerAir pollution also has a significant influence on hurricane formation, according to a new study. I learned that back in the 90's in highschool, might be a new study, but it's old knowledge that before the industrial age, wheather was much more violent in nautre than it is now, snowstroms, droped more snow, rains flooded more rivers, droughts where drier and more widespread.

Those who are especially sensitive to air pollution may experience shortness of breath, coughing, throat irritation, wheezing and breathing discomfort. For those who are especially sensitive to ozone, the PDEQ advises to limit the level of exertion outside between noon and 6 p. In the Atlantic, aerosol pollution peaked around 1980 and has been dropping steadily since.m. when elevated levels of ozone pollution are more likely to occur. On top of that the lack of cooling aerosols has helped push the jet stream — the river of air that moves weather from west to east on a roller-coaster like path — further north, reducing the shear that had been dampening hurricane formation.

Intense physical outdoor activity causes faster and deeper breathing, allowing ozone to penetrate into the parts of the lungs that are more likely to be injured. Ad “That’s why the Atlantic has gone pretty much crazy since the mid-90s and why it was so quiet in the 70s and 80s,” said climate and hurricane scientist Jim Kossin of the risk firm The Climate Service. Those who are most likely to be sensitive to ozone include children, adults who are active outdoors, people with respiratory diseases and certain individuals who have an unusual sensitivity to this particular pollutant. Motor vehicle exhaust, industrial and power plant emissions, gasoline vapors, chemical solvents and natural sources that emit oxides of nitrogen and volatile organic compounds that form ozone in the presence of intense sunlight and heat are all types of emissions that contribute to the creation on ground-level ozone.

Ad While aerosol cooling is maybe half to one-third smaller than the warming from greenhouse gases, it is about twice as effective in reducing tropical cyclone intensity compared to warming increasing it, said Columbia University climate scientist Adam Sobel, who wasn’t part of the study.
