http://news.bbc.co.uk/1/hi/world/europe/6725161.stm There is a mercury barometer, encased in what seems to be a cast iron housing, attached to a wall down by the water. One opens a wee hatch to read it and I have been known to sneak a peek from time to time. The above is the only mercury barometer I have ever seen (other than in pictures or museums) and I would say a 'traditional' barometer is an aneroid barometer, preferably in a brass housing. But I suppose time marches on. We used to have mercury barometers, steam trains, planes made from paper and string, and best of all, rickets. This is not to say I am a progressive type. -- Gianna http://www.buchan-meteo.org.uk * * * * * * * |

http://news.bbc.co.uk/1/hi/world/europe/6725161.stm Why is the picture that of an aneroid barometer? From a linked page: http://news.bbc.co.uk/1/hi/world/europe/4801434.stm Typical - ban the 'easy' targets leave the coal burning power stations etc.... Mercury is nasty, that's where the phrase "mad as a hatter" comes from and there was a serious case of mass poisoning in Japan from eating contaminated seafood but the exposure levels were rather high. I expect most of the population over about 35 have a fair amount of Hg in their mouths and have a far greater exposure to Hg from that source than the effectively sealed in glass mercury barometer. It's interesting that they are aiming to ban the sale of all products containing mercury. What about flourescent tubes? They all contain Mercury... I see the second article mentions schemes for the collection and recovery of the mercury from products containing it. So not only do we have a fridge mountain we'll shortly have a florescent light mountain as well. -- Cheers Dave. pam is missing e-mail |

This was mentioned on TWO a couple of months ago and (unusually for the BBC) it's little more than an anti EU rant. No, you won't (easily) be able to buy a new mercury barometer, but you will still be able to get old ones repaired. It's a mountain out of a molehill really.

" this and that when they patently haven't. Then we end up keeping the blatantly ridiculous pounds and ounces. Bring back pounds, shilling and pence, I say! Dave |

See Euromyths for more info: http://ec.europa.eu/unitedkingdom/pr...myth150_en.htm As I suspected. Thanks, Darren. Mercury (as the metal) is not really a hazard. Although pretty toxic its vapour pressure is very low. When I worked for BP I was using mercury as a hydraulic fluid and on one occasion the pipe burst, spraying fine droplets of mercury everywhere. The mercury detector in the lab just reached the 8-hour working exposure limit and it was situated close to the spill. I strongly suspect that if you had a mercury barometer and the tube broke and all the mercury fell on the floor and you left it there you would not be in any danger whatever. The mercury would get covered in dust and a film of household grease and dirt which would in effect reduce the vapour pressure even further. This effect is well-known among industrial chemists and perhaps the European Parliament, or least its advisors, know it as well. Mercury compounds, on the other hand, are very toxic if ingested. The Mad Hatters probably licked their fingers. It would not happen today or even 40 years ago. Staff would simply wear gloves and there'd be one or two other elementary safety precautions which people would take as normal even before we went safety-mad.

I visited a factory where they broke a mercury arc rectifer while I was on site - that prompted an emergency since these things don't contain just a few mgs! http://en.wikipedia.org/wiki/Image:M...-Rectifier.jpg (visiting the sub room was like visiting a b grade 50's horror film set!) |
