Study links air pollution exposure to Alzheimer’s


A potential link between exposure to air pollution and Alzheimer’s disease has been proposed by scientists in newly published medical research, according to Reuters
 
Scientists from the United Kingdom and Mexico examined the brain tissue of 37 people that have lived in highly air polluted cities, including Manchester and Mexico. The study found evidence of tiny spherical magnetite particles within brain tissue.
 
Due to the size and shape of the particles, scientists believe that the particles were created at high temperatures, suggesting the air pollution link. These particles are extremely similar to the magnetite particles that have been found in air pollution near busy streets caused from vehicle engines. Industrial sources and opening burning are also linked to the creation of magnetite particles. These particles have been linked to neurological diseases such as Alzheimer’s.
 
Air pollution can negatively impact the body in many other ways, including exacerbating respiratory ailments such as asthma.  When breathing in smog, affected people most commonly experience chest pain, coughing, throat irritation and congestion.  It can also cause premature death in individuals that have heart or lung disease, have suffered from a heart attack, or have irregular heartbeats and decreased lung function.

District hiring for 2 positions


The Yolo-Solano AQMD is currently recruiting for two vacancies.
 
The District is looking for an Engineering Manager to oversee our Engineering Division. The Engineering Division is responsible for air quality permit processing and rule development.
 
The District is also recruiting for an Air Quality Specialist within our Compliance Division. Specialists investigate potential air quality violations and inspect permitted sources.
 
Information on both openings and the District application are available at http://www.ysaqmd.org/announcements.php. The deadline to apply is 4 p.m. on October 12.

Davis wayfinding project begins


The City of Davis is developing a way to help bikers and pedestrians navigate more easily on local paths through its wayfinding project.
 
Davis is filled with bikeways and off-road pedestrian paths, all of which help promote active transportation. But navigating these paths can get confusing for both frequent users and visitors. 
 
The city will hold a public workshop on the wayfinding project from 6:30 to 8 p.m. on October 19 at Veteran’s Memorial Center.  Participants are asked to bring an 8.5–by-11-inch printed photo of what helps them navigate throughout Davis. These images will be on display throughout the meeting to help the project team come up with new and improved ways to navigate the city.
 
More information on the project can be found at http://cityofdavis.org/city-hall/public-works/davis-pathfinder-3672.

New federal truck standards to help clean our air


The federal government has set stricter standards for heavy duty vehicles that will help cut air pollution and improve fuel efficiency. 
 
The vehicles impacted by this range from pick-up trucks to 18-wheelers. The standards, adopted by the U.S. Environmental Protection Agency and the National Highway Traffic Safety Administration, are expected to lower carbon emissions by 1.1 billion metric tons and reduce fuel consumption by 2 billion barrels of oil over the life of vehicles produce under the new standards.
 
Improved fuel economy and reduced carbon emissions have the effect of also reducing air pollution. Emissions from cars and trucks cause approximately 70 percent of the Sacramento region’s summer smog. The Sacramento region, which includes Yolo-Solano AQMD, is currently in severe nonattainment for the nation’s smog standard.
