[ Focus on Chemical Machinery and Equipment Network ] Plastic pollution is increasingly becoming an environmental issue that needs urgent attenti.
Previously, studies on wild animals have shown that exposure to microplastics and nanoplastics is related to infertility, inflammation and cancer, but the current health effects on humans are uncle.
Now, a new study by researchers has found that human organs and tissues can absorb tiny amounts of nanoplastic and microplasti.

The research team tested 47 samples from the lungs, liver, spleen, and kidneys-these four organs may come into contact with, filter or collect microplastics-these samples come from brain and body tissue storage banks, these storage banks are for research Neurodegenerative diseases such as Alzheimer's disease are establish.
After exposing the tissue samples to a series of microplastics, through a mass spectrometer, they found that each sample contained traces of plastic, including polycarbonate (PC), polyethylene terephthalate (PET) and polycarbona.
Ethylene (P.

Another new study reveals how serious plastic pollution has reach.
Studies have shown that the content of plastic in the Atlantic Ocean is 10 times as much as people had previously realiz.

In addition, the relevant researcher said: “If we assume that the concentration of microplastics we measured at a depth of about 200 meters represents the concentration of microplastics in the submarine water at an average depth of about 3000 meters, then the Atlantic Ocean may contain about 200 milli.

In response to plastic pollution and other issues, my country has taken a series of measures, * and * issued the "National Development and Reform Commission * on further strengthening the management of plastic pollution", which pointed out that the mechanism and monitoring of plastic waste and microplastic pollution in rivers, lakes and seas should be strengthen.
, Research on prevention and control technology and policies, and carry out ecological environment impact and human health risk assessme.

In addition, the editor learned that at present, the commonly used microplastics identification techniques are Fourier transform infrared spectroscopy and Raman spectrosco.
However, the two can only analyze individual particles during the inspection process, and it is necessary to visually identify suspicious microplastic particles before performing spectral analys.
The study of microplastics in environmental samples requires the analysis of a large number of particles, which leads to a lot of time-consuming detecti.

Hyperspectral imaging technology combines the traditional two-dimensional RGB image with spectroscopy, and determines the chemical properties of the substance represented by each pixel by linking the spectral characteristics of each spatial pixel on the image with the corresponding spatial informati.

Compared with Fourier transform infrared spectroscopy and Raman spectroscopy, hyperspectral imaging technology can perform spectral analysis on a large number of samples at the same time, which* improves the detection efficiency, and can obtain other information such as the size, shape and abundance of microplasti.

With the development of science and technology, high-tech products are also used to monitor plastic environmental pollution, such as: researcher Lauren Bierman from the Plymouth Marine Laboratory in the United Kingdom and his colleagues according to the different wavelengths of visible light and infrared light absorbed and reflected by floating objects Using the data provided by the European Space Agency’s “Sentinel 2” satellite, a machine learning algorithm was trained to distinguish plastics from natural materials such as seaweed, wood, and fo.
Tests have shown that the average accuracy of this technology is 86%, and the local area is 10
The researchers said that this method is expected to be used in conjunction with drones or high-resolution satellites to monitor marine plastic debr.

Later, the editor would like to say that it is because of the wanton use of plastic by each of us that more and more "white garbage" are creat.
The idea of "recruiting and leaving" plastics is not realist.
To solve the white pollution problem, only combining science and technology with the joint efforts of people is a feasible w.
