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.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Earlier post.)

Researchers develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. —Nie et al.

Texas Clean Energy Project signs long-term CO2 offtake agreement with Whiting Petroleum for enhanced oil recovery; 90% CO2 capture from IGCC coal polygen plant

Green Car Congress

Its high carbon-capture rate reduces the total amount of CO 2 emitted to the atmosphere to less than 10% of the emissions for power from a conventional coal plant, and less than 25% of those for power from a highly efficient, natural gas-fired plant, according to Summit. Earlier post.). The project is supported by H.B.

First results from HEI/ACES murine study find few biologic effects from exposure to exhaust from new technology diesel engines

Green Car Congress

The study—a component of the Advanced Collaborative Engine Study (ACES)—is exposing rats and mice for 16 hours a day to emissions from a heavy duty diesel engine meeting 2007 US EPA standards that reduce emissions of fine particles and other pollutants by more than 90% from levels emitted by older engines.
