Conny Waters – AncientPages.com – A latest research from Tel Aviv College challenges long-held scientific views concerning King Solomon’s Mines and their affect on well being. Opposite to earlier beliefs, the research reveals that the traditional copper trade didn’t hurt staff’ well being, nor did it pose dangers to fashionable residents dwelling close by.

Researchers performed geochemical surveys at copper manufacturing websites within the Timna Valley, courting again to the tenth century B.C. through the time of Biblical Kings David and Solomon. Their findings point out that environmental air pollution from copper manufacturing was minimal and confined to particular areas, making certain no menace to previous or current inhabitants of the area. Moreover, TAU archaeologists reviewed earlier research and located no proof suggesting that this historic trade contributed considerably to world air pollution ranges.
“We inspected two main copper manufacturing websites within the Timna Valley, one from the Iron Age and King Solomon’s period and one other close by that’s about 1,500 years older,” says Professor Erez Ben-Yosef from the Jacob M. Alkow Division of Archaeology and Historical Close to Japanese Cultures, Chaim Rosenberg College of Jewish Research and Archaeology, Tel Aviv College.
“Our research was very intensive. We took a whole bunch of soil samples from each websites for chemical analyses, creating high-resolution maps of heavy metallic presence within the area. We discovered that air pollution ranges on the Timna copper mining websites are extraordinarily low and confined to the areas of the traditional smelting furnaces.
“As an illustration, the focus of lead—the first pollutant in metallic industries—drops to lower than 200 components per million only a few meters from the furnace. By comparability, the U.S. Environmental Safety Company defines industrial areas as protected for staff at 1,200 components per million and residential areas as protected for youngsters at 200 components per million.”
The brand new research contradicts a collection of papers printed because the Nineties about air pollution induced allegedly by the traditional copper trade.

“We show that this isn’t true. Air pollution in Timna could be very restricted spatially, and it is seemingly that solely these working immediately on the furnace suffered from inhaling poisonous fumes, whereas only a brief distance away, the soil is totally protected. Furthermore, the match we discovered between the spatial distribution of copper and lead concentrations within the soil additional signifies that the metals are ‘trapped’ in slag and different industrial waste—which retains them from leaching into the soil and affecting vegetation or people.
“Our findings align with a number of latest research from the Wadi Faynan area in Jordan, which additionally level to very low ranges of air pollution. Timna and Faynan are very best websites for the sort of analysis as a result of they haven’t been disturbed by fashionable mining, as occurred in Cyprus, for instance, and due to their dry climates, the metals within the soil will not be washed away,” Professor Ben-Yosef defined.
“In Faynan, a crew led by Prof. Yigal Erel of the Hebrew College examined 36 skeletons of people that lived on the mining website through the Iron Age, and solely three confirmed any hint of air pollution of their enamel. The remaining have been fully clear. We now current an identical image for Timna.”
Along with the geochemical survey, the TAU archaeologists additionally performed a complete evaluation of present literature, declaring that hypotheses about world air pollution through the pre-Roman interval lack strong proof.
“There was a pattern within the Nineties, which introduced historic copper production as the primary occasion of commercial air pollution,” explains Dr. Yagel, a number one researcher within the present research.
“Such statements seize headlines and entice analysis grants, however they unnecessarily venture fashionable air pollution issues onto the previous. Furthermore, the analysis literature tends to make use of the time period ‘air pollution’ to explain any hint of historic metallurgical exercise, and this has led to the mistaken assumption that metallic industries have been dangerous to people from their earliest beginnings—which is patently unfaithful.
“Even when metallic manufacturing was large-scale, changing into integral to human civilization, it was the poisonous lead trade that induced world air pollution, not essentially different metals. A Nineties research argued that traces of copper present in Greenland ice cores had traveled by means of the environment from websites like Timna. This declare, nonetheless, has not been corroborated by any subsequent research.

“As researchers confront the extreme environmental challenges of our time, corresponding to local weather change, we regularly are likely to seek for related issues previously or assume that environmental hurt has been an inevitable consequence of human exercise because the agricultural revolution. Nevertheless, we have to be cautious. Whereas we would label a couple of items of slag on the bottom as ‘air pollution,’ we must always not confuse this localized waste with regional or world environmental air pollution.”
