I am puzzled by the 5mm definition of microplastic. A 5mm fragment is quite visible, and surely too large to pass through many filters or be eaten by fish, etc. I mean, you’d notice it in your pasta. I always assumed the problem was with really much smaller, hardly visible , particles , say under 0.5mm .

That did occur to me as well... but I guess the particles that are really relevant to most of the discussion (and fears) are the nano-sized ones.

Good listening thanks. If you could figure out where roads go to that would be awesome. Not in the A8 ending in Greenock sense, but where the surface ends up when it wears out. There must be zillions of tiny bits of tarmacadam out there, along with dust from tyre wear which gets talked about a little more but not much.

Barium swallows, and the use of (oral) contrast and PET scans are both good analogies in that instance but completely different things!

Stuart if you ever wondered who the strange person staring at you whilst running past with a double buggy with two kids on Greendale then it was me. Alternatively iI might have just been staring a completely different person. I resolved to say hello the next time I saw you, but then I didn't see you again, and now I've moved to Canada for a year.

Love the podcast. It's terrific

oh dammit you're right: we got our scans confused there. Not surprised you moved to Canada for a year if you learnt you live near Stuart – with any luck he'll have left the area by the time you get back and you'll be safe again.
