According to Nikkei Asia magazine, Japanese researchers have discovered microplastic particles in clouds for the first time, raising concerns about the impact on ocean ecosystems.

Many believe that microplastics are introduced into the atmosphere when seawater condenses into clouds.

The research team, led by Professor Hiroshi Okochi of Waseda University, tested 44 water samples taken from clouds at the summit and foot of Mount Fuji as well as the peak of Mount Tanzawa-Oyama, west of Yokohama in Kanagawa Prefecture.

Analyzing the samples, the research team found a total of 70 microplastic particles, which could be classified into nine types. The size of the particles measured 7.1-94.6 micrometers and with an average concentration of 6.7-13.9 particles/liter.

Researchers say microplastic particles in clouds fall to the ground as rainwater, and can then enter the human body through agricultural products and livestock, negatively impacting health.
