What's Working

  • Garden Mosaics projects promote science education while connecting young and old people as they work together in local gardens.
  • Hope Meadows is a planned inter-generational community containing foster and adoptive parents, children, and senior citizens
  • In August 2002, the Los Angeles Unified School District (LAUSD) Board voted to ban soft drinks from all of the district’s schools

Air Pollution and Brain Damage

Publication Date:

May 31, 2002

Abstract:

This study of 200 dogs reared in Mexico City reveals, early in life, brain damage similar to that seen in the onset of Alzheimer's disease -- brain damage attributable to very fine particles in Mexico City's polluted air....

Size-Dependent Proinflammatory Effects of Ultrafine Polystyrene Particles...

Publication Date:

September 15, 2001

Abstract:

Study revealed that polystyrene ultrafine particles (without metals or other pollutants attached) can cause inflammation in the rat lung. Size alone can make ultrafine particles a health hazard....

Inhalation of Fine Particulate Air Pollution and Ozone Causes Acute Arterial Vasoconstruction in Healthy Adults

Publication Date:

April 1, 2002

Abstract:

Airborne particles less than 2.5 micrometers in diameter, together with 120 parts per billion ozone, cause the blood vessels to constrict in healthy adults....

Acute Effects of Inhaled Urban Particles and Ozone

Publication Date:

December 1, 1998

Abstract:

Study showing that fine particulate matter from urban air (4 to 5 micrometers in diameter) causes cardiovascular effects in exposed rats....

Ultrafine Particulate Pollutants Induce Oxidative Stress and Mitochondrial Damage

Authors:

Li, Ning; and others

Publication Date:

April 1, 2003

Abstract:

This study of cells showed that ultrafine particles (those with a diameter of 0.1 micrometers or less) are 10 to 50 times as potent at causing tissue damage, compared to fine particles with diameters in the range of 2.5 to 10 micrometers. Tiny particles can cause big lung damage....

Metal Composition of Ambient PM 2.5 Influences Severity of Allergic Airways Disease in Mice

Publication Date:

September 1, 2003

Abstract:

Children in two German cities have greatly different responses to airborne allergens, the differences correlating well with the varying levels of fine particles in the air of the two cities. This study was intended to see if the human results could be matched in mice exposed to fine particles and f...

Inhalation of Concentrated Ambient Air Particles Exacerbates Myocardial Ischemia in Conscious Dogs

Publication Date:

April 1, 2003

Abstract:

This laboratory study of dogs revealed that breathing fine particles greatly increased the effects of a simulated heart attack. This may explain why people who have heart attacks are more likely to die from them on bad-air days and more likely to survive them when the air is cleaner....

Chronic Exposure to High Levels of Particulate Air Pollution and Small Airway Remodeling

Publication Date:

May 1, 2003

Abstract:

Describes lung damage among non-smoking women who live in Mexico City, compared to healthier lungs of women living in Vancouver, British Columbia...

Airborne Particles of the California Central Valley Alter the Lungs of Healthy Adult Rats

Publication Date:

June 1, 2003

Abstract:

Rats exposed to fine and ultrafine particles in the air (comparable to the air on a bad day in Fresno, Calif.) suffered lung damage. Fine particles have a diameter less than 2.5 micrometers and ultrifine particles have a diameter less than 0.1 micrometers....

Distribution of Particulate Matter and Tissue Remodeling in the Human Lung

Publication Date:

November 1, 2000

Abstract:

Describes the destructive effects of fine and ultrafine particles on the lungs of humans in Fresno, California....
