Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

Accompanying the lower noise levels from bus traffic was a reduction of fatigue, day time sleepiness and low mood, a study at the University of Gothenburg shows. Previous noise-level measurements had indicated that disturbance from low-frequency noise in indoor environments was present in the residential area. Applied Sciences.

Study shows renewable diesel from crude tall oil is a high quality drop-in fuel for off-road engines

Green Car Congress

A team from the University of Vaasa (Finland) and UPM-Kymmene Corporation has examined how the blends of fossil and renewable diesel produced from crude tall oil (CTO) affect the performance and exhaust emissions of the modern common-rail off-road diesel engine. As the baseline fossil fuel, regular low-sulfur Finnish DF was used.

Imaging study: air pollution impairs function of blood vessels in lungs

Green Car Congress

Air pollution impairs the function of blood vessels in the lungs, according to a study of more than 16,000 patients presented at EuroEcho-Imaging 2016. The volunteers were exposed to ambient air or dilute diesel exhaust with a PM 2.5 EuroEcho-Imaging 2016. Patients with obstructive sleep apnea were at greater risk.

Team finds high concentrations of combustion- and friction-derived magnetic air pollution nanoparticles in human hearts in Mexico City

Green Car Congress

A 2016 study by Professor Maher and colleagues found abundant magnetite nanoparticles in brain tissue; magnetite is toxic and has been implicated in the production of reactive oxygen species (free radicals) in the human brain, which are associated with neurodegenerative diseases including Alzheimer’s disease.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

In four campaigns over the year-long study, the team from the University of Toronto measured emissions 15 meters from the roadway, then converted the measurements to fuel-based emission factors (EFs). Some projections expect the 2016 market share of new LDVs with GDI engines to exceed 50%. —Zimmerman et al. Wallace, and Greg J.
