法国马赛艾克斯大学Alain Véron小组研究发现，吉萨金字塔的建造导致了人为铜污染。这一研究成果于2024年7月22日发表在国际顶尖学术期刊《地质学》上。

据了解，吉萨金字塔的建设需要创造大量的金属工具，但这些早期冶金实例的重要性及其留下的污染被忽视了。

研究人员使用地球化学的方法，分析了埃及吉萨尼罗河洪泛平原上胡夫港的沉积物核芯，以追踪墓地的建设，特别关注冶金活动产生的铜污染。研究发现，在Khufu、Khafre和Menkaure国王在位期间，当地发生了严重的局部污染，这与准备和建造这些建筑期间的金属加工相一致。虽然金字塔建筑群为人类创造了一项杰出的文化遗产，但它也标志着吉萨出现了严重的人为金属污染。

Abstract: Although the construction of the Giza necropolis necessitated the creation of an extensive array of metal tools, the significance of these early instances of metallurgy, and the contamination they left, has been overlooked in favor of understanding pyramid building techniques. We geochemically analyzed a sediment core from the Khufu harbor, on the Nile floodplain at Giza, Egypt, to track the construction of the necropolis, with a particular focus on copper contamination deriving from metallurgical activities. We found that significant local contamination occurred during the regnal years of Kings Khufu, Khafre, and Menkaure, consistent with metalworking during the preparation and construction of the edifices. While the pyramid complex led to the creation of an outstanding cultural legacy for humanity, it also marked the onset of significant human-caused metal contamination at Giza.
