UC Davis study: traffic-related air pollution impacts early brain development

Green Car Congress

Researchers at the University of California, Davis, have found a link between traffic-related air pollution and an increased risk for changes in brain development relevant to neurodevelopmental disorders. The researchers compared the brains of rat pups exposed to traffic-related air pollution with those exposed to ?ltered

Study first to quantify amount of US pollution resulting from Chinese manufacturing for exports

Green Car Congress

Average annual percentage of black carbon pollution related to Chinese exports. China is responsible for only a small percentage of the annual pollution in the US, but powerful global winds known as “westerlies” can push airborne chemicals across the ocean in days, particularly during the spring, causing dangerous spikes in contaminants.

Xcel Energy, INL to use nuclear energy for clean hydrogen production; HTSE

Green Car Congress

It offers a view of the energy structures of the future, which will integrate systems to maximize energy use, generator profitability and grid reliability all while minimizing carbon emissions. Industrial-grade hydrogen is commonly produced today by stripping it from natural gas molecules, emitting carbon monoxide in the process.
