The London Congestion Charging Scheme (CCS)—which charged for travel into central London and reduced traffic volume ( earlier post )—has shown little evidence that it improved air quality as well, according to Part I of a new study published by the Health Effects Institute (HEI). µg/m 3. in PM 10.
Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. and PM 10 , including of NTP and TP emissions, at key selected London trial sites.
New research by scientists at King’s College London suggests that air pollution from London’s roads is improving overall but more work may be needed to tackle some sources of traffic pollution, which continue to breach limits in many parts of the city. 15–45%·year −1 ). No data was available to compare trends in ΔPM 2.5
Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough.
The International Maritime Organization (IMO) Sub-Committee on Pollution Prevention and Response (PPR) has agreed to move forward with a prohibition on the carriage of high-sulfur fuel oil for use on board ships, when that fuel oil is not compliant with a new low-sulfur limit which comes into force from 2020. Black carbon.
Mayor of Paris and Chair of C40 Cities Anne Hidalgo and Mayor of London Sadiq Khan announced they are working together to create schemes to score new cars based on their real-world emissions and their impact on air quality and to provide that data in an accurate and accessible form to the public. Earlier post.).
Mayor Hidalgo described her anti-pollution plan, which will be considered by the Conseil de Paris (the assembly governing the city) on 9 February, to the weekly Le Journal du Dimanche (leJDD) on 6 December. European regulations reduced pollutant emissions from diesel vehicles to those of gasoline vehicles. London, Berlin.)
An open-access paper on their work is published in the journal Environment International While the World Health Organization has not yet set a guideline for safe levels of ultrafine particles, it recognizes that particulate pollution overall is associated with negative impacts on cardiovascular and respiratory health.
In a recently published whitepaper on hydrogen opposed-piston engines (H 2 -OPE), opposed-piston engine maker Achates Power explained that since there are no carbon molecules in hydrogen fuel, neither unburned hydrocarbons nor particulate matter is a concern for emission control from a hydrogen combustion engine. Shell plc, London, England.
study led by UCLA researchers has revealed that the smallest particles from vehicle emissions may be the most damaging components of air pollution in triggering plaque buildup in the arteries, which can lead to heart attack and stroke.Another study, published in the New England Journal of Medicine, linked exposure to diesel exhaust with asthma.
In 2018, the Government will publish a comprehensive Clean Air Strategy which will address other sources of air pollution. Air quality in the UK has been improving significantly in recent decades, with reductions in emissions of all of the key pollutants, and NO 2 levels down by half in the last 15 years. 89M – Green Bus Fund.
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. Their findings indicated that emission control strategy retrofits are the least costly near-term intervention to reduce urban air pollution. Credit: ACS, Chong et al.
Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in adults over 60, according to new research led by Imperial College London and Duke University. Our research suggests that we might advise older adults to walk in green spaces, away from built-up areas and pollution from traffic.
Air pollution, and fine dust in particular, is calculated to contribute to more than four million deaths each year. While the mechanisms by which air pollutants cause cardiovascular events is undergoing continual refinement, the preponderant evidence support rapid effects of a diversity of pollutants including all particulate pollutants (e.g.
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.
That was rather dramatic climate change, but presumably that had nothing to do with mankind’s carbon dioxide emissions.” Rolling coal is also illegal, of course, because it involves deliberately modifying a diesel engine to make it more polluting (while also increasing horsepower, so it’s not all bad).
Michael Leiters , who was Ferrari’s chief technology officer (he recently left the company), says there’s no denying that electrification in the car industry is largely being driven by the need to comply with strict emissions regulations, including for carbon dioxide. A jaw-dropping weight-to-power ratio of 1.57 And don’t forget sound.
