Microplastics in Clouds: How New Research Changes Our Understanding of Pollution.

According to ТСН: Humanity has long known about the presence of plastic in soil, water, and even in the Arctic, but recently researchers have discovered it in places where we would prefer not to see it - in the clouds above us.

This alarming research was conducted by scientists who analyzed the air over two Chinese megacities - Guangzhou and Xi'an. Using innovative methods capable of detecting particles smaller than 200 nanometers (significantly smaller than the thickness of human hair), they obtained shocking results.

Large concentrations of microplastics and nanoplastics were found in the atmosphere. The scientists concluded that previous studies had significantly underestimated the scale of the problem - the amount of plastic in the sky turned out to be much greater.

Dangerous 'Plastic Rain'

The worst part of this situation is that these particles become part of the natural water cycle:

1. Suspension: the particles are light enough to remain airborne for a long time.

2. Cloud Formation: plastic acts as a condensation nucleus, aiding in cloud formation.

3. Precipitation: then these particles return to the ground in the form of rain, often far from the place where they entered the air.

The main sources of this pollution are considered to be road dust and evaporation after rain.

Threat to Health

Microplastics are already considered an increasingly common form of pollution associated with dangerous conditions in people:

• hormonal disruptions;

• cancer diseases;

• heart diseases;

• neurological damage;

• reproductive function issues.

“These results... offer critical insight into their transformation, fate, and potential consequences for climate, ecosystems, and human health.”

Although the study does not yet confirm that plastic is globally changing the climate, it shows that it already plays a significant role in the processes of cloud formation over cities.

Scientists have also found that the highest concentration of microplastics is in hot beverages such as tea and coffee.

Therefore, the results of this research raise new questions about the impact of plastic on the environment and human health. It is crucial to further study this problem, as we may find that we are surrounded by more dangerous particles than we previously thought.
