I noticed a similar thing describing a product on
(Not there today.)
I don't think landfill is the problem but other more eurofriendly methods of recycling. If these things are put in incinerators they all produce harmful toxins that might easily reach the atmosphere.
I rather think the general trend is a move away from landfill. And as for China, I think the move to more eco friendly ingredients would be a lifesaver there, as old computer parts are sent to China where illegal back street workshops maim (and even kill) hundreds if not thousands in the recovery of lead solder from pcb boards.
There was a Dispatches, or Horizon, or similar on this probably some 15 or more years ago. My recollection is that mercury release to the environment from crematoria chimneys is actually quite significant, at around 3g per person. There was some discussion about removing fillings, but that doesn't work, as after around 10 years, most of the mercury has left the filling amalgam and lodged somewhere else in the body (the brain seems to absorb mercury more than other body tissues).
You may be right, but equally there are lots of diseases which people get for which the cause is not yet understood.
The other large source of environmental mercury is from the flues of coal fired power stations, depending where in the world the coal was mined.
That's why the flue is fitted with an expensive "scrubber" (ooh-er!).
The free mercury, I'd go along with.
Mercury has a very low vapour pressure, therefore over a period of years it will eventually disappear as it evaporates.

Couldn't it be "re-bound" in some way, before landfill?
MM
Yes, your right
Yes and too long ago 1970-74. Left chemistry soon after as the pay was piss poor. Still is, thats why Chemistry depts are closing at all these Uni's, no one wants to take chemistry when they can get more driving a bin waggon.

It so makes me laugh, all this fuss about some things and not others. I have just watched the second half of Channel 4's food programme and we really must be the stupidest nation of shoppers on earth not to see through the supermarkets' ruses to get us to buy, at considerably inflated prices, "perfect" fruit and veg. The programme mentioned how more and more kids are becoming obese and suffering more from diabetes. In his School Meals series Jamie Oliver showed how kids fed a nutritious meal cooked from fresh ingredients lost a lot of their hyperactivity and became more teachable. We worry about lead leaching into groundwater, but pay little heed to the thousands of gallons of pesticide being sprayed on our food. Madness.

Same as the bags of nuts ' This product may contain nuts ' !!!

One of the problems with pcb boards is the plethora of connections that need soldering. We should have a lot more solid state devices that can be snapped together without solder. Modern motherboards look like they've been designed by that "Shakespeare" group of monkeys who have taken time off from their rows of typewriters. When will a "motherboard" be 1 inch square, consisting largely of take off points for network, modem, printer, VDU etc, all moulded into, not soldered onto, the package housing?

Apart from in Britain, of course...

It's good to find an explanation for one's stupidity. ;-(
So there are no strictures? Emission of mercury vapour (etc.) is legitimate? *I think not*.
? What is your answer to this?
I don't think that was the answer that the OP was looking for. Your answer was to a question that had not yet been asked. :-)
Dave In pedant mode. Sorry :-)
IIRC, the big problem at this time is not really lead in pcbs, but lead in the glass of CRTs (to stop X rays) in landfill. I seem to remember a figure of 250K tons/yr of lead being dumped from this source for the USA, so I guess we'll have about the same amount across Europe.

Ah well, atm, there are no regulations relating to the emissions of mercury from crematoria, but change is upon us...
The new regulations stipulate a maximum level of mercury emissions, which will necessitate the installation of specialist scrubbers, which cost lossa dosh - however, these scrubbers reduce the output levels to way below the required limits.
The newly "clean" crematoria can then sell their unused quota of allowable emissions to other crematoria, which have not installed the new scrubbers...
I'm sure that that must make sense to somebody :-)
And the allergy information on the milk bottle - "contains milk"
Not to be confused with the old scrubber going up the flue...
Wonder why? I thought it was health and safety issues at the point of manufacture, not use?
No, it's health and safety issues at the point of disposal.
