London CNN —Microplastics have been found in historic soil samples for the first time, according to a new study, potentially upending the way archaeological remains are preserved. In total, the study identified 16 different microplastic polymer types in contemporary and archived soil samples, the statement adds. While preserving archaeological remains in situ has been the favored approach in recent years, the new findings could trigger a change in approach, as microplastic contamination could compromise the remains’ scientific value. “The presence of microplastics can and will change the chemistry of the soil, potentially introducing elements which will cause the organic remains to decay. If that is the case, preserving archaeology in situ may no longer be appropriate.”The study was published in Science of the Total Environment.
