Showing results in Truck brake dust filters clean air


Although reducing vehicle tailpipe exhaust emissions remains a high priority in improving air quality, non-tailpipe emissions, such as those from brake wear, are likely to form an increasing proportion of total particulate emissions from road traffic, and may have specific health impacts associated with them. Therefore technology to reduce these emissions will also be required into the future, alongside exhaust emission reduction methods.


Evidence that carbonaceous particles may be translocated into the placenta during pregnancy has been reported by researchers from Queen Mary University of London at the European Respiratory Society congress. The study, undertaken with permission of five women who gave birth to healthy babies, isolated and screened 3500 placental macrophages and observed 60 cells which contained 72 particles.


The atmosphere of Saturn’s moon Titan appears as a thick orange haze, as a result of large hydrocarbons and organic aerosols. In the upper atmosphere, bombardment by extreme ultraviolet (EUV) radiation (wavelength 10-124 nm) and energetic particles produces large hydrocarbons via ion reactions. In the middle atmosphere (150-700 km altitude) these gaseous hydrocarbons are converted into particulates, but the exact details of this process are still subject to a deal of uncertainty.


Researchers at the Massachusetts Institute of Technology have developed an aerosolisable spray containing 2-D circuits, which could be used in a number of environmental and health applications where limited access and space prevents larger sensors being used. The polymer circuit, which contains a sensor element, a photodiode to supply power and a memory element to store recorded information, is fabricated on a 100 µm-square, 1 µm thick substrate of SU-8 photoepoxy, and then dispersed in suspension and atomised.


A recent Society member led event, represents the first step towards the co-creation of training and research programmes with academia that are considered essential by our public sector & industry partners.
The final report is now available regarding the Society’s role in building a UK research and innovation pipeline in aerosol science.


A 3 metre ‘diesel soot particle’ was installed in Bristol’s Millennium Square as part of the city’s Festival of Nature. The sculpture aimed to visualise what city-dwellers may be breathing in and to provoke conversations about air quality and health in cities by ‘making invisible air pollution visible’.
