@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian I was on a webinar not long ago where someone estimated that 80% of PM2.5 at Heathrow was from outside the region.

@Graham21 @imperialcollege @CentreEnvHealth @uniofleicester @guardian Quite possibly. These ultra fine particles are really numerous but have very little mass. It means that they don't really show up in PM2.5 measurements and are therefore overlooked in PM2.5 regulations, limits and assessments. They are definitely there and maybe affecting health.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Great story, Gary. Separate issue but curious if your team has done work on air quality impacts of garbage incineration? Am sure you’ve seen news of N. London councils’ @connectNLWA deal on Edmonton incinerator.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Thanks Gary, any info about the chemical composition of those (airplane) ultrafines? I remember there was uncertainty about it years ago, but I presume we know more now (I really should start attending the aerosol conferences again🤔)

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian My experience with the local villages around Heathrow told me there is a hierarchy of environmental concerns beginning with aircraft noise; air pollution and then CO2 emissions which hardly gets mention but none the less it’s there.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Would be happy to just start with taking air pollution from wood burning stoves more seriously. Wood burning is a significant contributor to air pollution in cities all around the world.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Have you in visibility the air pollution in the metro?

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian @DrGaryFuller , do monitoring stations close to airports monitor PM0.1? I don't think they do. This may be a real problem, since there is no WHO standard for these particles, as you mention on your article.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Don't have to look that far here. When the engines start (A320) the smell can come into the cabin. I always carry 3M elastomeric respirator with P2/P3 and multigas cartridges.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian Yes, and I think we should go even further and stop flying entirely.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian The air was a lot cleaner during the lockdowns. Of course the wood stinkers made up for it 10-fold.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian And we live 60km from Frankfurt and can smell the planes too. It has been found out by the ETH Zürich that the fuel additives of kerosine contain so many heavy metals that the contrail is actually already a chemtrail by itself.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian And in October of 21 while I was making nightime photos of our chimney stinker fog, I took some long esposures shots at the moon. Not getting the moon right but I saw the flight activity over our valley. And you cen bet these particles settle somewhere. Sometimes they do smell.

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian We've been doing research on BTEX concentrations at airports in South Africa. Great to see greater depth and insights from your results...

@DrGaryFuller @imperialcollege @CentreEnvHealth @uniofleicester @guardian This must be the same Guardian that published a piece on electric car brake pollution using a so-called expert. Electric cars don't use conventional brakes, but their motor-kinetic energy. My EV brakes are new after 110k miles. Next time you might want to look at home appliances
