A recent study has revealed that microplastics have been discovered in historic soil samples for the first time. This discovery could potentially change the way archaeological remains are preserved.
Researchers from the University of York in the United Kingdom discovered microplastics in soil deposits over seven meters (23 feet) deep. These deposits were originally laid down in the first or second century CE and were unearthed during excavations in the 1980s.
A recent study found a total of 16 different types of microplastic polymers in both modern and historical soil samples.

Microplastics are small plastic particles that are less than five millimeters in size, similar to the size of a sesame seed. They are created when larger pieces of plastic break down, either through chemical degradation or physical wear and tear.
Researchers have noted that microplastics were frequently used in certain beauty products until approximately 2020. In recent years, discussions about the increasing presence of microplastics in our environment have become more prevalent.
There are growing concerns about the effects of microplastics on the environment and human health. However, a new study has revealed that they may also have a significant impact on the field of archaeology.
In recent years, the preferred method has been to preserve archaeological remains in their original location. Yet, the discovery of microplastic contamination could lead to a shift in this approach. This is because such contamination has the potential to diminish the scientific value of these important historical artifacts.
John Schofield, a professor and director of studies in the University of York’s Department of Archaeology, expressed that the recent discovery of plastics in archaeological deposits is a significant revelation. He noted that deposits believed to be untouched for investigation are actually contaminated with plastics, including those sampled and stored in the late 1980s.

Plastics in the oceans and rivers are common, but now we are discovering toxic elements in our historic heritage. We will explore how this contamination affects the value and significance of these deposits.
David Jennings, the CEO of York Archaeology, shared why the presence of microplastics is a major worry.
"Our best-preserved remains, like the Viking artifacts found at Coppergate in York, were in waterlogged conditions without oxygen for more than 1000 years. This helped preserve organic materials exceptionally well," he explained.
"The introduction of microplastics into the soil can alter its chemistry, leading to potential decay of the organic remains. In such cases, keeping archaeology in its original location may no longer be the best option."
The study was published in Science of the Total Environment.
Editor's P/S:
The discovery of microplastics in historic soil samples is a sobering reminder of the pervasive nature of plastic pollution. It not only raises concerns about the preservation of archaeological remains but also highlights the urgent need to address the issue of microplastic contamination. The potential impact on the scientific value of these artifacts is significant, as microplastics can alter the chemistry of the soil and lead to the decay of organic materials. This could force archaeologists to reconsider their preferred method of preserving remains in their original location.
The study's findings underscore the importance of raising awareness about the long-term effects of plastic pollution. It is crucial to implement measures to reduce plastic consumption, promote recycling, and develop innovative solutions for microplastic removal. By working together, we can protect our historic heritage and ensure that future generations can appreciate the richness of our past.
