Caltech Researchers Measure a Major Chemical Contributing to Los Angeles Smog

By Lori Dajose, CALTECH

The Los Angeles region has some of the most polluted air in the United States, failing to meet standards set by the Environmental Protection Agency for the last decade. Now, Caltech researchers have quantified the levels of a component of smog called ammonium nitrate, a molecule that has been notoriously difficult to measure, and have found that there is much more of it than previously calculated, especially on the most polluted days.

The findings emphasize the need for the continued reduction of fossil fuel emissions from cars, trucks, and other industrial processes, which produce the precursor to ammonium nitrate, called nitric oxides or NOx.

The research was conducted in the Caltech laboratories of Paul Wennberg, the R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering, and Richard Flagan, the Irma and Ross McCollum-William H. Corcoran Professor of Chemical Engineering and Environmental Science and Engineering. A paper describing the study,

Pasadena Firefighters Face Lingering Health Effects from Eaton Fire Smoke Exposure

By ANDRÈ COLEMAN, Managing Editor

[UPDATED] Pasadena firefighters who responded to the devastating Eaton Fire earlier this year are now experiencing lingering health issues tied to smoke exposure, with blood tests revealing elevated levels of carcinogens, toxins, and metals, according to a report by KCAL News.

“Pasadena firefighters gave their all during the Eaton fire and were exposed to tons of lead, asbestos and other toxins. This wasn’t a wildfire,” Fire Chief Chad Agustin told Pasadena Now on Wednesday. “My role is to make sure they stay healthy. We are communicating with the best experts around the country on testing and frequency of testing.”

Firefighters from Station 38, who were among the first to arrive at the scene, reported a range of severe reactions following the fire, including burning sensations in their eyes and throats, persistent headaches, and overwhelming exhaustion.

According to Agustin, many firefighters had symptoms immediately after the fire, and although much of that has subsided,

LA County Supervisor Barger Leads Wildfire Recovery Roundtable In Washington

Local officials meet with federal lawmakers to address disaster recovery needs

Los Angeles County Board of Supervisors Chair Kathryn Barger led a bipartisan congressional roundtable discussion on wildfire disaster recovery in Washington, D.C. on Tuesday, May 20. The high-level meeting, hosted by Representatives Judy Chu and Brad Sherman and Senator Alex Padilla, brought together federal lawmakers, Los Angeles County leadership, and disaster recovery experts at the U.S. Capitol.

The roundtable aimed to spotlight the urgent need for federal support following devastating fires across California.

“Our communities are still reeling from the aftermath of recent wildfires, and it is our collective responsibility to ensure they are not left behind in the recovery process,” said Supervisor Barger. “We cannot afford to normalize disasters. We must strengthen our federal partnerships to better prepare, respond, and recover. Lives and livelihoods depend on that.”

The discussion, titled “Discussion on Fire Disaster Recovery,” addressed ongoing recovery efforts, housing displacement challenges, infrastructure rebuilding needs, and federal partnerships essential for mitigating future disasters.

USPS Designates Third Week of May As Mailbox Improvement Week

Annual initiative encourages customers to inspect and maintain mailboxes for safe and efficient mail delivery

The United States Postal Service has designated the third week of May (May 19–24) as Mailbox Improvement Week. This annual initiative encourages customers on both city and rural delivery routes to examine their mailboxes and, where necessary, “give their mailboxes a little love” to ensure safe, secure, and efficient mail delivery.

“Customers are encouraged to inspect, maintain, and upgrade their mailboxes to ensure safe, secure, and efficient mail delivery,” said the Postal Service in its announcement.

The United States Postal Service emphasizes that mailboxes should meet several key requirements to function properly. These include being approved by the Postmaster General, fully operational, designed to protect mail from weather, safe to use, conveniently located, neat in appearance, and large enough—within allowable size limits—to support daily mail and package volume (see United States Postal Service Delivery Growth Management).

Customers planning to replace their entire mailbox must consult with their local postmaster or station manager first.

Dodgers Foundation, Shoes That Fit, deliver sneakers and spirit to fire-impacted Webster Elementary students and staff

More than 500 brand-new pairs of sneakers landed at Webster Elementary School on Wednesday, part of a major donation effort led by the Los Angeles Dodgers Foundation and the nonprofit Shoes That Fit. The delivery was a show of solidarity for a campus that’s still healing from the emotional and logistical trauma of the Eaton Fire.

Webster Elementary and Cleveland Preschool were among the schools severely impacted when January’s blaze forced evacuations across Altadena and Pasadena. In all, more than 10,000 Pasadena Unified students had to evacuate, and nearly 1,000 students and staff reported losing their homes, said Pasadena Unified School District Board President Jennifer Hall Lee.

“I am here with people who are very special — the Webster Wolves,” said Hall Lee. “You are helping to restore joy and confidence in our students as they run around with friends or explore Webster’s garden and outdoor science classroom.”
