I was afraid of that... I better go study up before I have my "geek
credentials" revoked..... Especially now that its finally "cool" to be a
geek....

You're not a big enough geek. :)

That "fact" was brought up as an aside to the plot on CSI (las vegas) this
week... I watched a lot of star trek but I don't remember that being brought
up specifically. Do you need a secret decoder ring to know this or am I just
not a big enough geek? :-) Dharma

Dewey,

Actually, Spock himself would likely be banned since Vulcan blood chemistry
is based on Cu, instead of Fe, like ours ... hence the green color.

Try as hard as I may, I can not come up with a suitable Deweyism this early
in the day.

I think that's just spoculation on your part and I think they would allow
them based on their warped views of reality.

The StarTrek test.  If it doesn't look like something they'd use on
StarTrek, it's banned. 

Of course, the guys on the Enterprise had their own issues - those pesky
warp drives...  I don't think the EU would allow them.

I will be curious to see how products are tested for illegal substances once
all the known metals are effectively banned.

Some fresh news from the EU Commission  below
 
There is no argument that "uncontrolled  recycling" can be hazardous just as
drunk driving can be  hazardous. And how can one be against the protection
of children. 
 
The key is education and education is thus  vital. The parents are working
to feed their families. With the knowledge  of the potential for harm them
might cause by poor work habits,  they will make as many of the right
decisions as they are  capable of.  
 
What is a bit alarming is that the  author(s?) following sentence: 
 
"Of these metals, high levels of lead and  copper were the greatest cause
for concern" 
 
then going on to talk about lead issues  leaving apparent guilt by
association for copper. 
 
The there are a number of other troubling  aspects to the article such as
the use if "could be"  rather  than something more definite and the citing
sweeping transdermal  metal toxicity which is the first time I have seen
that in print.  

The item might well have been  sub-titled: "Be afraid... be very afraid"

targeted not only at the  recycler but also at the electronics manufacturer.
 
And so it goes...

Uncontrolled electronic waste  recycling threat to children's health

Current EU policy on Waste Electrical and Electronic Equipment (WEEE)
highlights the need for greater recycling of electrical and electronic
equipment to limit the total quantity of waste going to landfill.
However,  research carried out in China suggests that if recycling is not
carried  out safely then there is a significant risk to human health and the
environment. The researchers from Hong Kong studied Guiyu, a village in
southeast China which has a significant electronic circuit board recycling
industry.  
Villagers melt solder from the circuit boards and sort electrical
components, which they sell to electrical appliance factories. Circuit
boards contain many toxic metals. The researchers tested dust from the
recycling workshops, and also from the nearby road, food market and
schoolyard. They found high levels of dangerous heavy metals which would
have an impact on the health of the recycling workers and would pose a high
risk to children. 
The researchers tested for the metals cadmium, cobalt, chromium, copper,
nickel, lead and zinc. These metals can cause both acute and long-term
toxicity. 
Of these metals, high levels of lead and copper were  the greatest cause for
concern. High lead levels are associated with lower  IQ in children.
Other research has shown that both workers and children in  Guiyu have a
high incidence of bone disease, as well as digestive,  neurological and
respiratory problems, which may be linked to metal  toxicity. 
A risk assessment indicated that recycling workers could be exposed to 50
times the safe oral lead dose. Workers transport the metals into their homes
from the workshop as dust, transferring the dust to their children.
In a separate study, children of circuit board workers were found to have
higher levels of lead in their blood than those whose parents recycled
plastics. The metals get into the body through the skin or when dust is
inadvertently eaten or breathed in. The health risk to children at all
locations around the village was around eight times greater than that to
adults. 
Few studies to date have determined the extent of the problems caused by
uncontrolled electronic waste recycling. Similar waste is commonly recycled
in African countries as well as India and Vietnam. Awareness of the
consequences of uncontrolled recycling could prevent some of the same
mistakes being repeated in these countries. The amount of WEEE generated  in
the European Community is growing rapidly and Policy makers would like  to
see more WEEE recycling. 
The EU WEEE directive seeks to encourage safe  recycling, addressing issues
such as managing the risks of handling  hazardous components, which as this
case study shows, can cause concerns  if recycling is not carried out
safely.
