Simple solution is for commuters not to lick metal parts of the Tube on their journeys

[stuCameraman]

This isn't new news, ask the commuters who clean the black dirt from their nose when traveling on the tube every day....ive smelt the metal in the air since the 1990s, I commuted on the tube all through the 1990s and early 2000s and got laughed at when I wore a bike pollution mask around 1997 as I used the northern line most of the time. I think I have old video footage from the late 1990s of the cloudy northern line platforms.... As I was going to do an amateur documentary about underground pollution. I also noticed in the last 3 years the victoria line has got worse in terms of cloudy never used to be that bad.... Now its on par with the northern line in terms of cloudyness. Someone suggested big magnets around the tube to trap the metal particles, just like a car oil plug has a magnetic tip to catch tiny metal shavings from engine friction.... What a good idea👍🏼
