The waste was combinated with 1.7 per cent lead, other heavy metals and polycyclic aromatic hydrocarbons.

says we have 219 toxic pollutants in our bodies, and this includes preservatives, pesticides and heavy metals like lead and mercury.

(f) polymetallic sulphides means hydrothermally formed deposits of sulphide minerals which contain concentrations of metals including, inter alia, copper, lead, zinc, gold and silver

Heavy Metal

Heavy as lead.

'Heavy as lead.

Several metals such as lead, zinc and copper, with limited known reserves, are extensively used as building materials in construction.

Some of the declines, especially those of the prices of copper, nickel, zinc and lead, were particularly large (see table 1) as the depressed demand for those commodities has been compounded by problems of oversupply.

The reason for poor quality has been overly high pesticide and heavy metals quantities cadmium, lead and arsenic, coupled with incomplete and unharmonized declarations on the original packing of food.

The reasons for less than satisfactory quality of food were the increased levels of pesticides or heavy metals cadmium, lead and arsenic, while at the same time, the declarations on the original packing of the food were incomplete or non harmonized.

You don't buy. You sell. You sell lead in exchange for gold.

In addition, some countries specify as air pollutants heavy metals (such as lead and mercury), volatile organic compounds (such as benzene and formaldehyde) and a broad array of other chemical compounds classified as air toxics.

Iran claims that because of the pollutants from the oil well fires in Kuwait, its agriculture could suffer long term losses as a result of damage to the soil from the deposition of heavy metals (such as vanadium, cadmium and lead), soot and hydrocarbons.

I draw with a simple pencil, and at first, the Parkinson's was really upsetting, because I couldn't get the pencil to stand still.

MMCs have been shown to possess the following advantages over unreinforced metal alloys lighter weight, greater resistance to wear and impact, lower coefficient of thermal expansion and greater strength and stiffness.

It's lead!

Sell pencils.

Manufacturers and assemblers in developing countries have to substitute heavy metals such as mercury, lead and cadmium, as well as to respond to requirements of importers and customers downstream in the supply chain with regard to design for recycling and associated material selection.

Among the metals, copper prices declined by 36 per cent between June 1997 and February 1998, nickel by 24 per cent, zinc 22 per cent, and lead 16 per cent, while among the agricultural materials sawnwood prices fell by 34 per cent, rubber 29 per cent, wool 27 per cent, and jute 25 per cent.

And a pencil falls from the desk down to the floor, and I reach down to pick up the pencil.

Everything you see in this picture is commercial grade copper, lead, silver, zinc and gold.

Four years later, the lead recycling companies were held responsible for lead poisoning.

Have you got a pencil?

The point of the pencil has become dull.
