Cleaner than we were led to believe: Scientists uncover the truth about pollution in the mines of King Solomon.

In the 1990s, researchers claimed that ancient copper production was the first instance of industrial pollution. However, recent studies challenge this assertion.
Чистота, о которой мы не подозревали: ученые раскрыли правду о загрязнении Рудников царя Соломона.

Recent studies indicate that ancient mining operations were not a significant source of environmental harm. Research conducted by a team from Tel Aviv University revealed that copper mining at the King Solomon Mines had minimal environmental impact, writes IFLScience.

The debate regarding the ecological consequences of pre-industrial metallurgy has persisted since the 1990s. Scholars are divided: some suggest that metalworking in the Bronze and Iron Ages led to the emergence of pollutants detectable worldwide, while others argue that these industries were localized and environmentally safe.

Professor Erez Ben-Yosef and his colleagues examined copper mining sites in Israel's Timna Valley, dating back to the 10th century BCE. These mines are often linked to King Solomon, a prominent biblical figure.

By conducting geochemical analyses at two main sites—one from Solomon's time and the other approximately 1,500 years older—the researchers found that pollution was confined to areas surrounding ancient smelting furnaces.

Ben-Yosef explained: "We collected hundreds of soil samples and created high-resolution maps of heavy metal concentrations. The level of pollution was extremely low, limited to the immediate vicinity of the furnaces, and posed no significant threat to humans or the environment. The concentration of lead, for example, dropped to below 200 parts per million within a few meters of the furnace. In comparison, the U.S. Environmental Protection Agency considers areas with lead levels up to 1,200 parts per million safe for workers."

This localized pollution contrasts sharply with modern industrial contamination, where pollutants often spread over vast areas. The study showed that metals were effectively "trapped" in slag and other industrial waste, preventing leaching into the surrounding soil or vegetation.

Additional evidence from related studies in the Jordanian region of Wadi Faynan supports these findings: an analysis of 36 Iron Age skeletons revealed only minimal signs of pollutant exposure. The arid climate of Timna and Wadi Faynan, along with the absence of modern mining activities, has kept these sites untouched, allowing researchers to explore ancient practices with minimal interference.

Critics of previous studies point out a tendency to exaggerate the impact of early metallurgical activities on the environment. Dr. Omri Yagel, a co-author of the current study, noted: "In the 1990s, there was an attempt to portray ancient copper production as the first form of industrial pollution. While such narratives attract attention and funding, they often distort historical realities. For instance, claims that copper pollutants from Timna reached the glaciers of Greenland remain unfounded."

While ancient industries undoubtedly left localized marks, equating them with modern pollution risks distorts history. Understanding these differences is crucial for addressing contemporary environmental crises.
