Conny Waters – AncientPages.com – A latest examine 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 examine reveals that the traditional copper trade didn’t hurt staff’ well being, nor did it pose dangers to fashionable residents residing close by.

Researchers performed geochemical surveys at copper manufacturing websites within the Timna Valley, courting again to the tenth century B.C. in the course of 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, guaranteeing no risk to previous or current inhabitants of the area. Moreover, TAU archaeologists reviewed earlier research and located no proof suggesting that this historical 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 Historic Close to Jap Cultures, Chaim Rosenberg College of Jewish Research and Archaeology, Tel Aviv College.
“Our examine was very intensive. We took a whole lot of soil samples from each websites for chemical analyses, creating high-resolution maps of heavy steel 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 example, the focus of lead—the first pollutant in steel industries—drops to lower than 200 components per million just some meters from the furnace. By comparability, the U.S. Environmental Safety Company defines industrial areas as secure for staff at 1,200 components per million and residential areas as secure for kids at 200 components per million.”
The brand new examine contradicts a collection of papers revealed for the reason that Nineties about air pollution triggered allegedly by the traditional copper trade.

“We display 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 quick distance away, the soil is completely secure. 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 excellent websites for this kind of analysis as a result of they haven’t been disturbed by fashionable mining, as occurred in Cyprus, for instance, and because of their dry climates, the metals within the soil will not be washed away,” Professor Ben-Yosef defined.
“In Faynan, a staff led by Prof. Yigal Erel of the Hebrew College examined 36 skeletons of people that lived on the mining web site in the course of the Iron Age, and solely three confirmed any hint of air pollution of their enamel. The remainder had been fully clear. We now current the same image for Timna.”
Along with the geochemical survey, the TAU archaeologists additionally performed a complete evaluate of present literature, stating that hypotheses about world air pollution in the course of the pre-Roman interval lack strong proof.
“There was a development within the Nineties, which offered historical copper production as the primary occasion of commercial air pollution,” explains Dr. Yagel, a number one researcher within the present examine.
“Such statements seize headlines and appeal to analysis grants, however they unnecessarily mission 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 historical metallurgical exercise, and this has led to the mistaken assumption that steel industries had been dangerous to people from their earliest beginnings—which is patently unfaithful.
“Even when steel manufacturing was large-scale, changing into integral to human civilization, it was the poisonous lead trade that triggered world air pollution, not essentially different metals. A Nineties examine argued that traces of copper present in Greenland ice cores had traveled via the ambiance from websites like Timna. This declare, nonetheless, has not been corroborated by any subsequent examine.

“As researchers confront the extreme environmental challenges of our time, equivalent 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 for the reason that agricultural revolution. Nevertheless, we have to be cautious. Whereas we would label just a few items of slag on the bottom as ‘air pollution,’ we must always not confuse this localized waste with regional or world environmental air pollution.”
The examine was revealed within the journal Scientific Reports
