Here on earth, snails as well as lobsters, crabs and many (all?) of their  
land based arachnid brethren all employ copper in their blood as  oxygen getter 
but the blood is blue tinted.

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.
