Microplastics are already there in the rain

Micro-plastic was found by an American researcher in rainwater samples collected in the Rocky Mountains, the Guardian writes. This has virtually closed the circle: there is hardly any corner of the Earth where no plastic can be found. “I was expecting soil particles and mineral particles, but instead I found multicolored, microscopic-sized plastic fibers,” said Gregory Wetherbee, a scientist at the US Geological Survey (USGS).

“I think the most important lesson we can share with the American public is that much more plastic is polluting the world than can be seen. It’s in the rain, it’s in the snow. It is now part of our environment, “said Wetherbee, who published his study”…

Originally, Wetherbee wanted to investigate nitrogen pollution from rainwater samples collected in the Rocky Mountains of Colorado, but when he examined them with a microscope, he found plastic fibers, fragments, and particles in every color of the rainbow.

“My results are by accident,” he said, adding that the data he collected unfortunately rhymes well with a recent study that concluded from the microplastic contamination found in the Pyrenees that plastic particles on the wings of the wind were hardly visible or visible. they can reach hundreds and thousands of kilometers. (Other studies have reported that microparticle particles have reached the deepest points of the oceans, and have been found in many places in lakes, rivers, and even groundwater.

The main source of microplastics is simply untreated waste. Due to the weather, non-recycled, discarded, recycled plastics slowly but surely disintegrate into small fragments and fibers and enter the soil and waters. But not only rubbish, but also household activities thought to be harmless, abundantly enter the environment: for example, when washing synthetic fibers, a mass of microscopic plastic fibers get into the water, and some of them pass through finer filters when treating sewage.

For just over a decade, scientists have been regularly examining the plastic pollution of the seas, oceans and fresh waters, and know little about exactly where and how much of the micro-plastics get into the environment. They do not dare to estimate how much it is at present, nor do they have any idea of ​​how long it would take to decay if mankind would immediately stop the unbridled production of plastic trash.
