【Chemical machinery and equipment network Industry dynamics】Plastic is an important material in modern society, its plasticity is strong and wide range of applications, so it is widely used in product production, and even in the "plastic restriction order" and "plastic ban order" fully carried out today, plastic products are still everywhere in our lives and occupy an important position
.
The society we live in is therefore a society
wrapped in plastic.

The society we live in is therefore a society
wrapped in plastic.
Of course, the demand and usage have always been in a high state, and the abandonment situation cannot be underestimated
.
The Organization for Economic Cooperation and Development has released data that in 2019, the amount of plastic products used in the country reached 460 million tons, and the amount of plastic waste generated as a result exceeded 350 million tons, and worse, less than 10% of this plastic waste can be recycled
.
Therefore, the public's dependence on plastic products, in fact, is also in the development of history, and gradually become a threat
to us in the posture of plastic waste.
Nowadays, plastic pollution has also become one of the
major problems plaguing environmental and ecological construction.

Therefore, the public's dependence on plastic products, in fact, is also in the development of history, and gradually become a threat
to us in the posture of plastic waste.
Nowadays, plastic pollution has also become one of the
major problems plaguing environmental and ecological construction.
Among the plastic waste, there is a very troublesome type of garbage - microplastics
.
Microplastics are the main carrier of plastic pollution, generally plastic particles below 5 mm formed after the deterioration of plastic waste
.
The main problem with this plastic waste is its small size (particle size ranges from a few microns to a few millimeters), irregular shape, so it has a large specific surface area and is difficult to distinguish with the naked eye, and is an important carrier
of viruses and bacteria.
In addition, because the production of microplastics is closely related to the use and abandonment of plastic products in our daily lives, they are very easy to be discharged into lakes and oceans, and once they flow, these microplastics become difficult to recycle
.
Eventually, microplastics will affect the entire ecosystem of nature through the marine life chain, including us
.
Because of this, microplastics also have a "name" - PM2.

in the sea.
So how many microplastics are discharged into the sea in a year? This data is difficult to come up with an accurate answer, but the Japanese team has given the answer
to the amount of microplastic pollution in the Arctic Ocean in a year.
A team led by Takashi Ikegami, deputy director of the Japan Maritime Research and Development Agency, recently published observation-based speculations, which mentioned that about 18 billion microplastics flow from the Pacific Ocean to the Arctic Ocean a year, equivalent to 420 tons of plastics flowing into the sea
in the form of microplastics every year.
It is reported that the data was calculated by the team between 2020 and 2021 by investigating plastic in seawater collected in the Bering Strait between Russia and Alaska, which is the entrance to the Arctic Ocean from the Pacific Ocean, so the accuracy and reference value of the data are guaranteed

Conclusion: Microplastic pollution is a long-term pollution, and the harm it can cause is immeasurable
because it cannot be recycled well.
Fortunately, countries are beginning to pay attention to this problem and have introduced relevant restrictive policies, such as Canada, Ireland, the Netherlands and the United Kingdom have enacted legislation to ban the production
of cosmetics and personal care products containing microbeads.
But a more important question is how to deal with existing marine microplastic pollution
.
From the perspective of technological development, the detection of these microplastics generally relies on near-infrared spectroscopy
.
Thanks to the development of satellite technology, the detection of marine near-infrared microplastic pollution with the help of satellites in the future may be a breakthrough to alleviate the problem of marine microplastics, but all this requires waiting time and technology to give us an answer
