Are Legally Acceptable Levels of Pollution Harming Children’s Brain Development?
Between 1955 and 1970, the United States passed five laws to monitor and regulate the country’s air pollution. Each act built upon the last and, in 1970, Congress passed the Clean Air Act, which established guidelines for “safe” levels of ambient air pollution, some of which are still used today. But a new study suggests those standards -
Study shows traffic-related air pollution in Irvine weakens brain function
Anna Aldrich, University of California, Irvine The brains of wild type (WT) and Alzheimer’s (APP) mouse models were analyzed after exposure to purified air (Con) and ultrafine particulate matter (PM) for the presence of astrocyte cells. These were visualized by staining them green (left column), with potentially harmful and activated astrocytes appearing in red (middle -
California becomes the first state to adopt emission rules for trains
April 27, 2023 SACRAMENTO, Calif. — California approved Thursday a first-in-the-nation, ambitious rule limiting rail pollution to aggressively cut greenhouse gas emissions in the state’s latest move to establish itself as a global leader in the fight against climate change. The rule will ban locomotive engines more than 23 years old by 2030 and increase -
EPA proposal takes on health risks near US chemical plants
By MICHAEL PHILLIS The Associated Press In what could prove a significant move for communities facing air pollution, the Environmental Protection Agency proposed on Thursday that chemical plants nationwide measure certain hazardous compounds that cross beyond their property lines and reduce them when they are too high. The proposed rules would reduce cancer risk and -

2023-01-01Impact of roadside conifers vegetation growth on air pollution mitigation
This study examines how the growth of conifer trees planted alongside roads affects their ability to reduce traffic-related air pollution over time. Researchers found that as conifers grow taller, they become less dense, and the ideal tree height for maximum pollution reduction is between 4 and 6 meters. The findings suggest that regular pruning is essential to maintain roadside vegetation barriers at their most effective size for improving air quality in nearby communities. -
