Who led the research group that conducted this study on transparent goldfish?

The research group was led by Professor Toshinobu Tokumoto of the Graduate School of Science and Technology, Shizuoka University.

What specific size and type of microplastics were used in the exposure experiment?

The researchers used fluorescently labeled microplastics with a diameter of 2 micrometers.

The results revealed that when fish are exposed to microplastics present in water, accumulation in the gills occurs first.

Long-term accumulation in the gills led to necrosis of gill tissue, which eventually resulted in the death of the fish.

The research results were published online on March 23, 2026, in the journal "Toxicology Mechanisms and Methods."
