Parents Fear Kids at Risk From Dangerous Dust at Silicon Valley School

July 18, 2019

A new school next to a concrete plant in Silicon Valley poses a serious health risk to the children and adults there. 

The National Institutes of Health and several other federal agencies, including OSHA, CDC and the EPA have reported on the health hazards of dust from concrete manufacturing facilities. Ultra-fine particles in the dust can lodge into the lungs, ultimately traveling to the heart. As a result, exposure can cause respiratory problems and even lead to cardiac arrest.

Regional Deposition of Tobacco Smoke in the Lung

Description: The toxicity of tobacco smoke depends on the local dose of the smoke in the lung, yet mapping of the regional and local deposition are not available. Mathematical modeling techniques such as the Multi-Path Particle Dosimetry (MPPD) model can predicted the distribution of deposition, but these predictions have not been validated due to lack of experimental data.

Air Pollution in National Parks

May 13, 2019

Recently the National Parks Conservation Association (NPCA) published a report stating that 85% of parks deal with unhealthy air due to ozone. While ozone is thought of typically resulting from vehicle and industrial emissions, park plants also emit compounds that react with NOx gasses to make ozone.

May 02, 2019

"Thomas Cahill, professor emeritus of physics and atmospheric sciences, died from complications of cancer on April 30, 2019, in Davis. He was 82.

"During his five decades in research, Cahill delighted in applying his physics expertise to problems in the public sphere, especially those in environmental science. He engaged in battles to save Mono Lake, remove lead from gasoline, protect air quality in national parks, and safeguard first responders following the 2001 World Trade Center disaster."

Weaknesses in Benicia's Air Monitoring System discovered after Valero's march Pollution Release

April 11, 2019

In March, Valero's Benicial refinery spit out pollution which caused city officials to warn residents to stay indoors. The Bay Area Air Quality Monitoring District sent a van to monitor the situation because currently there is no stationary air quality monitoring device in the residential areas despite the fact that it's home to one of the largest refineries in California. 

As explained in the article "Valer's March Pollution Release Exposes Weaknesses in Benicia's Air Monitoring System" by Ted Goldberg: 

KQED: Valero's Benicia Refinery Now Target of Several Probes Into Pollution Releases

March 26, 2019

An article by Ted Goldberg of KQED News has looked into the release of a large unexpected plume of petroleum coke dust by Valero's Benicia refinery. The release had local fire officials encouraging people with respiratory problems to avoid activity outdoors. 

A partial shutdown of the facility resulted from this incident. This is considered the worst breakdown since a 2017 power outage.
