为了更全面地了解高酸度对星星卡尔中石器时代遗址骨的影响，已使用一套分析技术来评估在不同强度的硫酸溶液中处理一系列骨类型对无机和有机部分的影响。这些方法包括质量损失分析、扫描电子显微镜、手性氨基酸分析和粉末X射线衍射。骨矿物质的损失显示在低pH下严重加速，这最终导致骨胶原的分解增加。考古样本比现代样本面临的风险更大。通过诸如此类的研究，了解酸度增加对有机人工制品的影响，不仅在确定星星卡尔的未来管理方面，而且在确定具有类似化学环境的其他地点方面，都具有重要的应用价值。
In order to more fully understand the effects of high acidity on bone at the Mesolithic site of Star Carr, a suite of analytical techniques has been used to assess the effects on the inorganic and organic fractions of treating a range of bone types in different strength sulfuric acid solutions. These include mass loss analysis, scanning electron microscopy, chiral amino acid analysis, and powder X-ray diffraction. Loss of bone mineral is shown to be severely accelerated at low pH and this ultimately leads to increased breakdown of the bone collagen. Archaeological samples are significantly more at risk than modern samples. Reaching an understanding of the effects of increased acidity on organic artefacts through studies such as this has important applications in determining the future management not only of Star Carr, but other sites with similar chemical environments.
