Microplastics Found in Clouds Raise Alarming Concerns

In a groundbreaking discovery, Japanese researchers have identified microplastics within clouds, shedding light on a disconcerting environmental issue. The implications of this finding extend to potential repercussions for ocean ecosystems, climate change, and human health.

Led by Waseda University professor Hiroshi Okochi and a dedicated research team, the study involved the examination of 44 water samples collected from cloud formations. The analysis unveiled that these cloud waters contained no fewer than 70 microplastic particles, marking a significant milestone in environmental research.


The water samples were obtained from various locations, including the summits and foothills of Mount Fuji and the summit of Mount Tanzawa-Oyama, located west of Yokohama in Kanagawa prefecture.

As the researchers say, “To the best of our knowledge, this is the first report on airborne microplastics in cloud water.” Microplastics, minuscule plastic particles, have typically been discovered in industrial discharges or have resulted from the breakdown of larger plastic waste. Their presence is not confined to the environment but extends to human and animal bodies, found in organs such as the lungs, heart, blood, placenta, and feces.

A staggering 10 million tons of these plastic fragments find their way into the ocean, where they are propelled into the atmosphere as ocean spray, effectively infiltrating the air we breathe and the water we consume.

This revelation underscores that microplastics have become an integral component of clouds, raising concerns about pervasive “plastic rainfall” that contaminates our food and water supplies.


 The presence of microplastics in clouds carries significant implications for climate change. If not addressed proactively, it can lead to irreversible environmental damage and ecological risks.

Okochi has sounded a cautionary note, stating, “If the issue of ‘plastic air pollution‘ is not addressed proactively, climate change and ecological risks may become a reality, causing irreversible and serious environmental damage in the future.” Furthermore, when exposed to sunlight and ultraviolet radiation at cloud altitudes, microplastics can contribute to the generation of greenhouse gases.

This revelation underscores the pressing need for coordinated efforts to mitigate the presence of microplastics in our atmosphere and highlights the urgency of addressing this multifaceted environmental challenge.
