Late Bronze Age. It seems very likely that, at least in the Late Bronze Age, the Minoans were involved in a substantial metal trade, if for no other reason than that metal deposits on Crete are rare, but Late Minoan bronze objects are plentiful. The nature and organization of the copper trade in the Late Bronze Age is particularly intriguing.

They also noticed that many of the European metal pieces were chemically identical, leading to the idea that chemical groups, rather than individual metal pieces, could be used to assess the minimum number of metal trade vessels. The metal in European trade items was often more valuable as the metal itself instead of as an item such as a kettle. They surmised that as few as two to four copper pots and three brass kettles could have provided all the 39 pieces of European copper and brass.

Tin is not mentioned by name in Holy Writ before the Flood, circa 4000 b.c. The word occurs five times afterwards in the Old Testament and is mentioned along with silver, iron and lead as one of the metals traded in the fairs of Tarshish, the modern Andalusia of Spain (Ezek. xxvii. 12). As already stated, however, (p. 9) the so-called tin was an alloy of copper and tin, but containing a higher percentage of the latter metal than the ancient brass or bronze. 

Once the factors to be included in the plan are chosen, scales reflecting the different degrees within each factor are constructed. Each degree may also be anchored by the typical skills, tasks, and behaviors taken from benchmark jobs that illustrate each factor degree. Table 4 shows the National Metal Trade Association s scaling for the factor of knowledge.

Lead was amongst the metals traded by the Phoenicians of Tarshish (probably in Spain) who obtained it from the Kassiterides (usually believed to be the British Isles) and from the Andalusian mines in Spain (Partington, 1934).

The demand for metals as commodities is determined by the international trade cycle. Supply and demand are rarely in equilibrium, and for this reason there is a need for an international terminal market as a gathering of traders to purchase and sell metal, establishing a net supply-demand balance and setting prices accordingly. The bulk of metal traded on world markets is contracted directly between producer and consumer, but is priced on the basis of the international terminal market quotation. 

Industrial hygiene began life in the metals trade. Mining and smelting of metals were the backbone of technological and industrial growth. Indeed, whole eras of human development are associated with the increasing sophistication with which humankind has worked with metals the copper age was succeeded by the bronze age that was in turn succeeded by the iron age. We are embarked on a new age characterized by new materials that define our civilization it may eventually be known as the silicon age. 

Metal fume fever is an old syndrome that is quite well known, not so much by doctors, but by those who are especially at risk of suffering from it, such as welders or other workers in metal trades (Blanc 1993). The most frequent and best documented cause of metal fume fever is that caused by heating zinc. Zinc fumes, which oxidize to fine particles of zinc oxide (ZnO), are produced, for instance, when zinc is smelted to make alloys, when zinc-containing scrap metal is molten, when metal surfaces are sprayed with zinc or when galvanized steel is welded or cut. Metal fume fever occurs when the fumes are not properly exhausted, which is often the case when these jobs are done in enclosed spaces. Both freshly formed zinc fumes and fine zinc oxide dust have the ability to cause metal fume fever. 

Refined lead trade statistics do not separately identify flows of primary and secondary metal, and from the buyer s point of view this is clearly not a serious omission. They also do not distinguish between different qualities of metal traded, and this may be more problematic. However, it seems likely that the vast proportion of refined lead traded is high quality (99-99 per...
