Recent research has uncovered microplastic contamination in archaeological sediment samples, raising concerns about the long-term preservation of buried heritage assets. This discovery challenges current preservation strategies As a result, the argument for keeping long-term archaeological deposits untouched is being called into question..
Researchers found various types of MP polymers, including those used in food packaging and automotive parts, in significant quantities within the archeological samples. Moving forward, decision-makers will need to weigh the potential risks of MP contamination against the benefits of in situ preservation. As we grapple with this unexpected intersection of modern pollution and ancient history, finding the right balance between preserving our past and building our future has become more crucial – and more complicated – than ever.
