The hidden challenges of detecting nanoplastics in our food supply
In short: A review of nanotoxicology literature found that while microplastics are a major environmental concern, our ability to track even smaller nanoplastics in the food chain is severely limited. Researchers identified three potential pathways for toxicity: the particles themselves, the pollutants they carry, and the chemicals that leach from them.
The review notes that current analytical techniques are biased because they can only detect particles significantly larger than the nanorange. This makes it difficult to assess the true presence of nanoplastics in food.
While current data on microplastics in food does not yet predict adverse health effects, the authors suggest that the potential toxicity of nanoplastics remains poorly studied and requires urgent investigation.
Why it matters: Our current tools may be blind to the smallest, potentially most impactful plastic particles in our food.
