They found that the <a href=\"https:\/\/scientificult.it\/en\/category\/natural-sciences\/environmental-science\/\">environmental<\/a> pollution resulting from copper production was minimal and spatially restricted, posing no danger to the region&#8217;s inhabitants either in the past or today. Additionally, TAU&#8217;s <a href=\"https:\/\/www.classicult.it\/en\/category\/antiquities\/archaeology\/\">archaeologists<\/a> reviewed previous studies and found no evidence that the ancient copper industry polluted the planet.<\/p>\n<p>The study was led by Prof. Erez Ben-Yosef, Dr. Omri Yagel, Willy Ondricek, and Dr. Aaron Greener from the Jacob M. Alkow Department of Archaeology and Ancient Near Eastern Cultures, Chaim Rosenberg School of Jewish Studies and Archaeology, Tel Aviv University. The paper was published in the prestigious journal\u00a0<em><a href=\"https:\/\/www.nature.com\/articles\/s41598-024-80939-5\">Scientific Reports<\/a><\/em>\u00a0by\u00a0<em>Nature<\/em>.<\/p>\n<blockquote><p>\u201cWe inspected two major copper production sites in the Timna Valley, one from the Iron Age and King Solomon\u2019s era and another nearby that is about 1,500 years older,\u201d says Prof. Erez Ben-Yosef. \u201cOur study was very extensive.\u00a0 We took hundreds of soil samples from both sites for chemical analyses, creating high-resolution maps of heavy metal presence in the region. We found that pollution levels at the Timna copper mining sites are extremely low and confined to the locations of the ancient smelting furnaces. For instance, the concentration of lead \u2014 the primary pollutant in metal industries \u2014 drops to less than 200 parts per million just a few meters from the furnace. By comparison, the U.S. Environmental Protection Agency defines industrial areas as safe for workers at 1,200 parts per million and residential areas as safe for children at 200 parts per million.\u201d<\/p><\/blockquote>\n<figure id=\"attachment_213280\" aria-describedby=\"caption-attachment-213280\" style=\"width: 770px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-213280\" src=\"https:\/\/www.classicult.it\/wp-content\/uploads\/2023\/07\/Hula-Valley-handaxes-4-1024x938.jpeg\" alt=\"Prof. Erez Ben-Yosef.

Courtesy of Tel Aviv University, CC BY<\/figcaption><\/figure>\n<p>The new study contradicts a series of papers published since the 1990s about pollution caused allegedly by the ancient copper industry.<\/p>\n<blockquote><p>\u201cWe demonstrate that this is not true. Pollution in Timna is very restricted spatially, and it\u2019s likely that only those working directly at the furnace suffered from inhaling toxic fumes, while just a short distance away, the soil is entirely safe. Moreover, the match we found between the spatial distribution of copper and lead concentrations in the soil further indicates that the metals are \u2018trapped\u2019 in slag and other industrial waste &#8211; which keeps them from leaching into the soil and affecting plants or humans. Our findings align with several recent studies from the Wadi Faynan region in Jordan, which also point to very low levels of pollution. Timna and Faynan are ideal sites for this type of research because they have not been disturbed by modern mining, as happened in Cyprus for example, and thanks to their dry climates the metals in the soil are not washed away. In Faynan, a team led by Prof. Yigal Erel of the Hebrew University examined 36 skeletons of people who lived at the mining site during the Iron Age, and only three showed any trace of pollution in their teeth. The rest were completely clean. We now present a similar picture for Timna.\u201d<\/p><\/blockquote>\n<p>In addition to the geochemical survey, the TAU archaeologists also conducted a comprehensive review of existing literature, pointing out that hypotheses about global pollution during the pre-Roman period lack solid evidence.<\/p>\n<blockquote><p>\u201cThere was a trend in the 1990s, which presented ancient copper production as the first instance of industrial pollution,\u201d explains Dr. Omri Yagel, a leading researcher in the current study. \u201cSuch statements grab headlines and attract research grants, but they unnecessarily project modern pollution problems onto the past. Moreover, the research literature tends to use the term \u2018pollution\u2019 to describe any trace of ancient metallurgical activity, and this has led to the mistaken assumption that metal industries were harmful to humans from their earliest beginnings \u2014 which is patently untrue. Even when metal production was large-scale, becoming integral to human civilization, it was the toxic lead industry that caused global pollution, not necessarily other metals. A 1990s study argued that traces of copper found in Greenland ice cores had traveled through the atmosphere from sites like Timna. This claim, however, has not been corroborated by any subsequent study. As researchers confronting the severe environmental challenges of our time, such as climate change, we often tend to search for similar problems in the past or assume that environmental harm has been an inevitable consequence of human activity since the agricultural revolution. However, we must be cautious. While we might label a few pieces of slag on the ground as &#8216;pollution,&#8217; we should not confuse this localized waste with regional or global environmental pollution.\u201d<\/p><\/blockquote>\n<figure id=\"attachment_289891\" aria-describedby=\"caption-attachment-289891\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-289891\" src=\"https:\/\/www.classicult.it\/wp-content\/uploads\/2025\/12\/Low-Res_1.-Dr.-Omri-Yagel-recording-the-precise-sampling-location.jpeg\" alt=\"Dr. Omri Yagel recording the precise sampling location.
