Cleaner Air in California as a Result of the Stay-at-home Order

In a KCRA 3 article, the UC Davis Air Quality research Center's Director, Anthony Wexler, explains why we have been experiencing much better air quality currently. 

“There’s very little traffic compared to what there normally is, and so there’s much less emissions from cars and trucks than there normally are,” Wexler said. “That gives us this blessing at this time where we need as many blessings as we can get. It gives us the blessing of wonderful air quality.”

English Scientists Link Coronavirus Deaths to Exposure to toxic Air

How Toxic Air Leads to Higher Coronavirus Cases and Deaths

Comparing annual daily averages of NOx and NO2 levels to total coronavirus cases and deaths, researchers at the University of Cambridge have found that higher levels of pollution have lead to higher coronavirus cases and deaths. This research suggests a correlation and further research is required to confirm the link between toxic air pollution and coronavirus cases and deaths. 

Air Pollution and Brain Health

April 10, 2020

What is Air Pollution? What is the evidence linking air pollution to adverse effects on the brain? How does air pollution alter brain development and brain function? These are just a few of the questions answered in the publication "Air Pollution and Brain Health" by Professor of Neurotoxicology Dr. Pamela Lein and Distinguished Professor Dr. Anthony Wexler of UC Davis.

COVID-19 death rates increase due to long-term exposure to PM2.5

April 07, 2020

More and more we are seeing results from recent studies showing a correlation between higher COVID-19 death rates and people who live in air pollution riddled areas. Both in Italy and the United States, people that reside in areas with higher concentrations of PM2.5 in the atmosphere are at least 12% more likely to not survive a bout with COVID-19. These findings are consistent with the findings from the 2002-2003 SARS outbreak that claimed 349 lives in China. 

Aerosols within the coronavirus pandemic

Does COVID-19 transmit via expiratory particles?

UC Davis Air Quality Research Director, Dr. Tony Wexler, looked into what role aerosols play in the transmission of coronavirus particles with colleagues William Ristenpart (UC Davis), Nicole Bouvier (Icahn School of Medicine at Mount Sinai), and Sima Asadi (UC Davis).

Reviewing the brief knowns on aerosol transmission of particles and earlier research on other coronavirus', they argue

that speech plausibly serves as an important and under-recognized transmission mechanism for COVID-19.

How would the air quality change if electric cars were the norm?

March 31, 2020

With the coronavirus spreading and stay-at-home orders becoming more prevalent we are seeing a drop in emissions resulting in better air quality. People around the US and the World are reporting being able to see further across cities and to hills or mountains. 

Coronavirus pandemic leading to huge drop in air pollution

March 25, 2020

COVID-19 was declared a pandemic earlier this month causing industries across the world to shutdown and workers to stay home to avoid further contamination and spreading of the virus. This emergency shutdown has lead to lower air pollution levels around the world. 

Experts are saying that this societal shutdown is creating one of the largest experiments in industrial emission reduction. NO2 levels over cities and industrial areas have decreased significantly in comparison to this same time in 2019. 

University of Leicester air pollution professor, Paul Monks, stated

Map of U.S. Auto Emissions

January 28, 2020

More than 60% of transportation emissions come from passenger vehicles in the U.S. This makes personal transportation the largest source of greenhouse gases.  "Boston University’s emissions database, first published in 2015 and updated this month with an additional five years of data, reveals that much of the increase in driving-related CO2 has occurred in and around cities."

Take a look at your cities emissions and how they have changed over the years. 

"The bigger story is climate change"

December 12, 2019

Air Quality Research Center Director, Tony Wexler, spoke with Mark Kaufman of Mashable about the smoke and poor air quality in Sydney from the Australia fires. Sydney's pollution levels were more than 11 times the hazardous level. 

In his article, Sydney, engulfed in smoke, has a ghastly air quality problem, Kaufman shares:
