Invisible Plastic Clouds Detected in China: What the New Particles Threaten.

According to ТСН: Invisible 'plastic clouds' have been detected over major cities in China. A recent study showed that there are significantly more micro and nanoplastic particles in the air over Guangzhou and Xi'an than previously thought.

Scientists point out that over the past 20 years, microplastics have become a global pollution problem — they are found in soil, water systems, living organisms, and even in the atmosphere of polar regions. Various studies link these particles to hormonal disruptions, cardiovascular and oncological diseases, as well as reproductive function disorders and neurological issues.

Research and Results

However, key questions remained unresolved: how many particles are actually in the atmosphere, how they move, and what role they play in climatic processes. Chinese researchers employed new technologies to detect particles sized from 200 nanometers and analyzed plastics in aerosols, precipitation, and lifted dust.

Measurements revealed that concentrations of micro and nanoplastics can vary by 100–100,000 times depending on conditions. A major part of this pollution is formed by road dust and precipitation after rain.

Impact on Ecosystems and Health

Researchers note that tiny particles can remain airborne for a long time and also contribute to cloud formation. Eventually, they may fall to the ground with precipitation, sometimes at considerable distances from the emission sources.

The authors of the study emphasize: these are the most detailed estimates to date of plastic content in the atmosphere — a segment of the global plastic cycle that has until now been considered the least studied. Although the impact of these particles on the climate is not yet measurable with precision, the study indicates that they play an important role in the cloud formation process and may pose risks to ecosystems and human health.

Microplastics continue to be an important topic for scientific research, as their impact on the environment and human health is not yet fully understood. The results of this study highlight the need for further research on atmospheric pollution by microplastics to understand their long-term effects on nature and health.
