Exposure to Soot Particles May Increase Premature Death Rates


LA Testing provides soot, carbon black and combustible by-product analysis to ensure safe breathing environments.

An extended epidemiological analysis was recently released by the nonprofit Health Effects Institute. The analysis was conducted by scientists at the University of Ottawa for the institute which was created by the Environmental Protection Agency and the industries it regulates to create unbiased studies.

The scientists reviewed existing studies with links between soot particles and premature deaths related to cardiovascular diseases. The findings showed that the mortality rate for those people exposed to the tiny soot particles was double the rate previously believed.

The analysis covered 116 American cities and compiled data from 500,000 people. Some areas with the highest soot levels included the eastern suburbs of Los Angeles and California’s Central Valley. A review of the data found that the risks of having conditions that are a precursor to fatal heart attacks for people in areas with high levels of soot increases by 24% as particle concentrations increase.

Soot is a general term that refers to impure carbon particles that result from the incomplete combustion of hydrocarbons. It is produced by a number of sources including coal fired power plants, oil refineries, diesel engines, waste incinerators, forest fires and furnaces to name a few sources.

LA Testing, an affiliate of EMSL Analytical, is a leading provider of soot, carbon black and combustible by-product laboratory analysis. “The number of Americans that live in urban areas or near industrial areas with elevated soot levels is enormous,” reported Ben Sublasky, National Director of Client Services for LA Testing and EMSL Analytical. “LA Testing provides expert analysis for soot to ensure those most at risk in our society can have the air they breathe tested to ensure they are not subjecting themselves to unnecessary risks,” Sublasky concluded.
