Study links exposure to diesel exhaust particles to pneumococcal disease susceptibility

Green Car Congress

Researchers from the University of Liverpool, Queen Mary University, London and Trinity College Dublin have linked exposure to diesel exhaust particles (DEPs) to susceptibility to pneumococcal disease. What we did not know however, was how pollution, such as diesel exhaust particles, actually causes airway disease.

London study finds taxi drivers face highest levels of black carbon compared to other professional drivers

Green Car Congress

The research also found that taxi drivers experience the highest exposures to black carbon, an indicator of diesel engine fumes, compared to couriers, truck drivers, waste removal and emergency service workers. The research was presented by Shanon Lim, a research assistant and PhD candidate at King’s College London, UK.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al. Dunmore et al.

London police trialing Suzuki Burgman fuel cell scooters; first trial outside of Japan

Green Car Congress

The London Metropolitan Police Service (MPS) has begun a trial to test Suzuki Burgman hydrogen-powered scooters. The 4kW stack from Intelligent Energy offers power for other applications, including range extension for battery-powered electric vehicles, four wheel vehicles and auxiliary power—especially for diesel replacement.

U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO.

Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel

Green Car Congress

Annual GHG emissions relative to BASE Scenario (BASE Scenario = 949 kt CO 2 e on a 100-year GWP basis) for differing London bus fleet technology options. Researchers from the University of Cambridge have conducted a comprehensive environmental cost–benefit analysis of near-term alternative bus technologies. Credit: ACS, Chong et al.
