June 2017 We might not all have the luxury of a front garden but adding greenery to the front of our houses and flats, even in a window box, is one way of helping to combat air pollution. Continue reading
22 March 2017 That was the question posed by Caroline Russell last night at a content-packed meeting of over 80 representatives from every London borough. There were informed mini-presentations from Simon Birkett @CleanAirLondon, Prof Frank Kelly (Kings College), Alice Monroe (Doctors Against Diesel) @DieselDrs, Louise Francis @Mapping4Change, Andrea Lee @Client Earth, Prof Andrea Seller @Sellerthechemist, Lara Houston and Dr Jennifer Gabrys @citizensense.
All the participants lived outside the proposed ULEZ extension zone of the North and South Circular and were fully aware of very high measurements of NO2 and Particulate Matter polluting their air quality. ‘We want to breathe clean air too’ and this won’t happen without change. Last night we investigated ways that we can encourage more people to sign the petition to extend the ULEZ to the whole of Greater London: https://you.38degrees.org.uk/petitions/extend-the-ultra-low-emission-zone-to-the-whole-of-london Continue reading
Air Quality Brentford are taking a closer look at the results from the air quality recorded at the A4/Glenhurst Road monitor. The results are available for all to see at http://www.airqualityengland.co.uk, select LB Hounslow and create graph. We think it’s important for more local residents to be aware of the high peaks in NO2 and PM10 emitted by diesel vehicles throughout the day. To help raise awareness we are making our own screengrabs of the results and publishing these on twitter every day @agreenerlondon
Air quality is measured as an annual average and the legal annual average for Nitrogen Dioxide (NO2) is 40 ugm and hourly there should be no more than 18 exceedances of 200 ugm per year. The legal annual average for Particulate Matter (PM10) is 40 ugm-3 and over a 24 hour period no more than 35 exceedances in a year over 50 µg m-3.
The example above shows the results for 9 March, a beautifully sunny day but the levels of NO2 only dipped below 40ugm at 4am and midnight – this is however still legal as the limit hasn’t gone over 200ugm. This toxic gas is invisible but you can probably smell or taste it in the air. Both Nitrogen Dioxide and Particulate Matter are harmful to humans, these very small particles are breathed in to the lungs and even enter the bloodstream affecting our immune system, and we need to start taking a little more notice of these very high levels of pollution. The levels of Particulate Matter on this day were illegal as they were over 50ugm.
Green Dragon Primary School received their free packs of Woodland Trust trees and hedges last week, the little saplings arriving just in time to plant during their Science Week. We went along to see how they got on. Each class was given the responsibility of planting one tree each throughout the week, labelling them with their class name and watching over them as they grow. Trees and plants take in Carbon Dioxide (CO2) and in return create Oxygen (O2) which we all need to live. They also help to absorb the toxic emissions of Nitrogen Dioxide (NO2) and Particulate Matter (PM10) which are made in particular by diesel vehicles driving along our busy roads, so we are encouraging the planting of trees, plants and flowers everywhere in Brentford.
27 October 2017: We met with Phil Hurst, the Arboriculturist for TfL, and councillors Guy Lambert and Myra Savin to walk from Boston Manor Road along the A4 to the M4 slip road, identifying locations that new trees could be planted and which trees would be suitable. 30 trees were already to be planted between Gillette Corner and Boston Manor Road, and it was agreed to plant a total of 64 new trees along the A4 through Brentford.
