Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

The scientists showed that there are a number of organic molecules from diverse sources present in modern concrete structures and asphalt pavements: phthalates, diesel exhaust particulates, surfactants, and windshield washer fluids. Organic matter in water accelerates deterioration of asphalt pavements. Akihiro Moriyoshi, et al.

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

Diesel-powered commuter trains may expose their passengers to elevated levels of certain black carbon and ultrafine particles, especially in the coach directly behind the locomotive, according to a new study from researchers at the University of Toronto. A paper on the study is published in the journal Atmospheric Environment.

ARB study compares in-use NOx emissions from diesel, hydraulic hybrid diesel and LNG refuse trucks

Green Car Congress

A team from the California Air Resources Board (ARB), in partnership with the City of Sacramento, has characterized the in-use emissions from model year (MY) 2010 or newer diesel, liquefied natural gas (LNG) and hydraulic hybrid diesel engines during real-world refuse truck operation. Diesel 1, which was certified at 0.18

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A European study lead by scientists at the University of Edinburgh (UK) has found that the combustion-derived ultrafine particles from diesel fuel are the predominant mediators of the adverse effects—harming blood vessels and increasing the chances of blood clots forming in arteries, leading to a heart attack or stroke.

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.
