Amid ongoing stay-at-home orders, L.A. has some of cleanest air of any major city

Dr. Yifang Zhu, a professor of environmental health sciences at UCLA’s Fielding School of Public Health, said that she and her colleagues identified a similar trend.

Zhu’s team also found a 40% drop in levels of PM 2.5, a class of microscopic air pollutants that have been linked to serious cardiovascular and respiratory problems, especially in children and the elderly. A study released Monday, by Xiao Wu and Rachel C. Nethery of Harvard University, also linked exposure to PM 2.5 to an increased risk of death from Covid-19.

PM 2.5 ends up in our air from many sources, but Zhu said vehicle traffic is a big contributor in Southern California.

Since California’s stay-at-home order went into effect, Zhu’s team has found that traffic across the state has fallen by around 80%.

1. I haven't been able to drive anywhere

without first assessing the time of day and which freeway would have the least amount of traffic since I moved here in 1984. I am actually finding that driving can be an enjoyable experience. A silver lining in this disaster.

2. Yes, if you're lucky enough to still have a job, your commute is heavenly.

There is no rush hour traffic. It is surreal.
