[Article Publication] A paper on titanium dioxide nanoparticles in ocean, in which JAMSTEC/Kochi Core Principal Researcher (Visiting Professor at Hiroshima University) Tomioka participated, was published in Frontiers in Marine Science.

Titanium dioxide nanoparticles negatively impact marine ecosystems and public health, and although Ammonia veneta possesses a detoxification mechanism to uptake and expel titanium dioxide nanoparticles, this function breaks down at concentrations exceeding 5 ppm, leading to inhibited growth. Given that current coastal environments exhibit titanium dioxide nanoparticle accumulation far exceeding the detoxification capacity, it is crucial to investigate the toxic mechanisms to prevent further disruption of marine ecosystems (Published paper url).
