It’s raining microplastics in Arctic – Australia

“We found microplastics in every sample analysed,” she said. “We hypothesise that it’s coming from global background contamination, rather than a specific source point.”

Over time, plastic materials can erode into increasingly smaller pieces, allowing them to become transported through the atmosphere. The widespread detection of microplastics suggests that this movement could be contributing to plastic particles being deposited across both urban and remote environments.

However, the study also highlights the limitations of current analysis. Dr Jaeger said the testing could reliably identify particles down to 20 micrometres, but this did not mean microplastics stopped at that size.

“The smaller we go, the more particles we find,” she said. “Below that size, it becomes much more difficult to reliably analyse them, so there is still a lot that we don’t know.”
