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.

CNN —A small stone vial discovered in southeastern Iran contained a red cosmetic that was likely used as a lip coloring nearly 4,000 years ago, according to archaeologists. More than 80% of the analyzed sample was made up of minerals that produce a deep red color — primarily hematite. The substance found in the stone vial was made from different minerals — including hematite, shown in red. Whether the vial from Iran was the earliest lipstick, “all comes down to what this new discovery was actually used for,” she said. The rest is slowly emerging from new excavations.”It’s not clear who would have worn the lipstick — or in what context.
