@DrGaryFuller @ucl @guardian I definitely did not see this coming... It is pretty interesting though, and another reason for more organic farming and greenhouses. Agrivoltaics may help.

@DrGaryFuller @ucl @guardian Thanks for putting this article together, knowing how eating cheese and milk products contributes heavily to air and river pollution is a very important addition to awareness of what needs to change. But, my god… doesn’t the Guardian need to find alternative funding streams?!

@DrGaryFuller @ucl @guardian You couldn’t make this 💩up. Oh, you just did.

@DrGaryFuller @ucl @guardian 😂

@DrGaryFuller @ucl @guardian So agricultural ammonia is the next big thing in #AirPollution ?

@DrGaryFuller @ucl @guardian Weird comments on here. Sound like the issue of particle pollution is more complcated that we first realised. Sounds like every other problem we are facing.

@DrGaryFuller @ucl @guardian Note one abandoned solution proposed in 1919 following the use of trench light railways in WWI: Light rail for agriculture. This from @BNArchive . #LostCambridge @tcmurray @CambridgeGreens @NatalieBen

@DrGaryFuller @ucl @guardian Now who financed that study? 🤔

@DrGaryFuller @ucl @guardian All particles are undesirable but I guess that this is mostly above 10 μm

@DrGaryFuller @ucl @guardian Why is it farmers ge t the blame for this. Ad blue in all new diesel cars is basically pumping urea straight into the atmosphere and yet rising levels of nitrates ate from farmers despite falling levels of nitrogen fertiliser use.

@DrGaryFuller @ucl @guardian Where is your research for dust and particulates from tyres and brake pads, caused by people driving erratically?

@DrGaryFuller @ucl @guardian How many City Farms are there polluting the air? Last Farm I saw was in the countryside miles away from a city. I call Bull💩 on this survey!

@DrGaryFuller @ucl @guardian We HAVE to up our game. Most particles harmless (think sea spray). Some are the most carcinogenic non-radioactive substances known to science.

@DrGaryFuller @ucl @guardian What are these farm origin particulates- ammonia compounds? How does data inform your modelling? Incinerators use ammonia to reduce NOX emissions, and NH3 emissions are not regulated.

@DrGaryFuller @ucl @guardian Our company fixes this problem at the farm. RO Membrane tech to dewater slurry, dry the concentrate & make fertiliser pellets plus capture the ammonia as liquid fertiliser. Costs £££s. Can be done now
