Energy saving light bulbs 'contain cancer causing chemicals'
Fears have been reignited about the safety of energy saving light bulbs
after a group of scientists warned that they contain cancer causing
chemicals

Their report advises that the bulbs should not be left on for extended
periods, particularly near someone's head, as they emit poisonous materials
when switched on.
Peter Braun, who carried out the tests at the Berlin's Alab Laboratory,
said: "For such carcinogenic substances it is important they are kept as far
away as possible from the human environment."
The bulbs are already widely used in the UK following EU direction to phase
out traditional incandescent lighting by the end of this year.
But the German scientists claimed that several carcinogenic chemicals and
toxins were released when the environmentally-friendly compact fluorescent
lamps (CFLs) were switched on, including phenol, naphthalene and styrene.
Andreas Kirchner, of the Federation of German Engineers, said: "Electrical
smog develops around these lamps.
"I, therefore, use them only very economically. They should not be used in
unventilated areas and definitely not in the proximity of the head."
British experts insisted that more research was needed and urged consumers
not to panic.
Dr Michelle Bloor, senior lecturer in Environmental Science at Portsmouth
University, told the Daily Express: "Further independent studies would need
to be undertaken to back up the presented German research."
The Department for the Environment insists the bulbs are safe, despite the
fact that they contain small amounts of mercury which would leak out if the
glass was broken.
Advice on its website states: "Energy efficient light bulbs are not a danger
to the public.
"Although they contain mercury, limited at 5mg per lamp, it cannot escape
from a lamp that is intact.
"In any case, the very small amount contained in an energy efficient bulb is
unlikely to cause harm even if the lamp should be broken."
The latest report follows claims by Abraham Haim, a professor of biology at
Haifa University in Israel, that the bulbs could result in higher breast
cancer rates if used late at night.
He said that the bluer light that CFLs emitted closely mimicked daylight,
disrupting the body's production of the hormone melatonin more than
older-style filament bulbs, which cast a yellower light.
The Migraine Action Association has warned that they could trigger migraines
and skin care specialists have claimed that their intense light could
exacerbate a range of existing skin problems.

Specifically, what chemicals are emitted when the bulbs are on?

Then don't eat them, FOOL!
