No we aren't.


Indeed.

That this is a myth has been explained many times before, but for
those whose religion appears to be opposing anything green
http://www.bbc.co.uk/dna/actionnetwork/A22400182 provides some
information on the subject.


The figures in there are a little out of date, and not for the EU.
We're better than that now with CFLs. Typical mercury contents
of new CFLs is now down to 3mg. Another 2.5mg is given off in the
electricty production, which is 5.5mg total. For an equivalent
filament lamp, 10mg is given off in the electricity production.

IIRC, the EU max permitted mercury in a CFL is 5mg, but that would
have been written some time ago, and advances have allowed less
to be used since then.
