Reference, please.

It may cost $10k to clean up a major mercury spill (eg in the old HVDC
valve houses at Haywards and Benmore), but surely not for the
miniscule amount used in modern fluorescent tubes or bulbs.

How much mercury is released by burning coal to generate electricity?

Mercury is a metal that is liquid at room temperature. Coal is solid
carbonized organic matter made over many tens of thousands of years under
high geological pressures.

There is probably lower quantities of mercury in coal than there is gold
in coal.

"Natural sources such as volcanoes are responsible for approximately

"Natural sources such as volcanoes are responsible for approximately
half of atmospheric mercury emissions. The human-generated half can be
divided into the following estimated percentages:

* 65% from stationary combustion, of which coal-fired power plants are
the largest aggregate source (40% of U.S. mercury emissions in 1999).
This includes power plants fueled with gas where the mercury has not
been removed. Emissions from coal combustion are between one and two
orders of magnitude higher than emissions from oil combustion, depending
on the country.
* 11% from gold production. The three largest point sources for mercury
emissions in the U.S. are the three largest gold mines"

http://en.wikipedia.org/wiki/Mercury_(element)

"Smokestack emissions from coal-fired power plants are the primary
source of mercury pollution in the U.S.

Every year, coal-fired power plants release 48 tons of mercury
nationwide. "

The Hg content of coal appears to be measurable in 10s of mg per kg of
coal. Gold at that level would be revovered.

How does that relate to usage here in NZ?

There's a lot of mercury in coal. There's more happened to those dead
weeds of long ago that just getting squeezed.

There's also a boatload of uranium in coal. If you want to be safe from
radioactivity, build nukes.

Usage of what in NZ?

You were stating there wasn't any Hg in coal. I (and several others)
pointed out that you were wrong. But as is your usual fashion you will
completly side step that won't you?
