New analysis finds Asia produces twice as much mercury emissions as previously thought

Green Car Congress

New analysis by an international team led by MIT researchers shows that Asia now releases a surprisingly large amount of anthropogenic mercury. The new analysis provides more accurate estimates of sources of mercury emissions around the world. Noelle Selin, the Esther and Harold E.

Exposure to airborne metal pollution associated with increased risk of mortality

Green Car Congress

Although there is ample evidence that air pollution—specifically airborne. A European study has used wild moss samples to estimate human exposure to airborne metal particles in order to analyze the relationship between atmospheric metal pollution and risk of mortality. —Bénédicte Jacquemin.

Aggregated damage costs by pollutant. The EEA quantified the damage costs arising from CO 2 emissions based on estimated marginal abatement cost. There are differences between the selected pollutants in terms of the extent of current knowledge about how to evaluate their impacts. Source: EEA. Click to enlarge. Click to enlarge.

Study from Thuringia shows 50% of harmful soot comes from local sources, 50% from long-distance transport

Green Car Congress

Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. Black carbon is associated with primary emissions from combustion processes from anthropogenic sources (car, domestic heating and industry) or biogenic sources (e.g. forest fires).

EPA report shows progress in reducing urban air toxics across US; 50% reduction from mobile sources since 1990

Green Car Congress

The US Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress—the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics (also referred to as hazardous air pollutants or HAPs).
