Imagine, one half acid (+H) and one half base (-OH)... what could be
more corrosive.

Don't water it down; tell us how you really feel about it.

Hello, Tim
Yes, indeed, copper is a dangerous substance, especially beryllium
copper, and it should not be ingested or smoked. I am sure the EU
weenies are well-meaning, probably having inhaled some through a copper
pipe in their earlier days of experimenting with alternative lifestyles
and they know how harmful it can be. I am sure they simply don't want
anyone else to experience the brain-rotting that they inadvertently
experienced.
But copper is not nearly so dangerous as Dihydrogen Monoxide, which is
one of the best cleaning solvents known, especially when heated. I hope
the EU weenies and the self-appointed California environmental experts
never find out about Dihydrogen Monoxide; if they took a look at the
MSDS I think they would choke when they see how much of this dangerous
cleaning solvent is present in their bodies. It has been known to kill
in both its liquid and solid forms. People die from it every day. I was
just reading that at least 25,000 people were killed either directly by
it or as an indirect result of coming into contact with it just in the
last couple of weeks.
Yet, as dangerous as it is, it is a chemical we cannot do without in the
electronics industry. I am almost afraid to post this, as I am sure it
will quickly be added to the list of banned chemicals in the upcoming
REACH legislation.
Just last night on TV I saw several big tough guys fall down on top of a
sheet of hardened Dihydrogen Monoxide. There were several injuries
reported. It is definitely not something to fool around with, and should
be controlled so idiots don't kill themselves due to overexposure, or
hurt someone by playfully throwing it at friends while it is in its
plastic range between liquidus and solidus.

I have been in conferences where speakers recommended that copper metal
be banned from use in products. When I asked one California
environmentalist how he determined copper was hazardous, he said he read
an MSDS. It is true that an MSDS for copper metal will state that
copper is hazardous. For
example:
WARNING! HARMFUL IF SWALLOWED OR INHALED. CAUSES IRRITATION TO SKIN,
EYES AND RESPIRATORY TRACT. AFFECTS THE LIVER AND KIDNEYS. CHRONIC
EXPOSURE MAY CAUSE TISSUE DAMAGE.
SAF-T-DATA(tm) Ratings (Provided here for your convenience)
Health Rating: 3 - Severe (Life)
Flammability Rating: 1 - Slight
Reactivity Rating: 2 - Moderate
Contact Rating: 1 - Slight
Lab Protective Equip: GOGGLES & SHIELD; LAB COAT & APRON; VENT HOOD;
PROPER GLOVES Storage Color Code: Green (General Storage)
But the key here is to look at the qualification of the hazard: "Harmful
if swallowed or inhaled". That means only if swallowed or inhaled. But
the Precautionary Principle allows the EU to ignore such trivial facts.
In the US, all electronics manufacturers will now probably have to label
their products as follows: "Contains copper metal. Harmful if swallowed
or inhaled. Do not swallow or inhale this product." But that will not
be enough for the environmentalists - they will want to ban copper, just
so no one could possibly inhale or swallow it.
No more lead, PVC or copper pipes. What are we going to use for
plumbing?

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.
