【Chemical machinery and equipment network hot attention ] Recently, the United Nations Environment Programme (UNEP) released the report "From Pollution to Solution: Global Marine Garbage and Plastic Pollution Assessment"
.
The report points out that 85% of marine garbage is plastic; it is estimated that by 2040, the volume of plastic garbage flowing into the ocean will be close to three times the current volume, and 23 million to 37 million tons of plastic garbage will be discharged into the ocean every year

The report points out that 85% of marine garbage is plastic; it is estimated that by 2040, the volume of plastic garbage flowing into the ocean will be close to three times the current volume, and 23 million to 37 million tons of plastic garbage will be discharged into the ocean every year
.
The report also pointed out that plastic waste will have a severe impact on human health, the global economy, biodiversity and climate
.
For example, plastic waste in water bodies can enter the human body through seafood, drinking water or even salt, while plastic suspended in the air may penetrate the skin or be inhaled into the body
.
These plastics may change the body's hormone levels, disrupt development, harm reproductive function and cause cancer
.
Marine organisms may be poisoned by plastic waste, have behavioral disorders, starve, suffocate, or cannot receive sunlight
.
In addition, in 2015, the global greenhouse gas emissions brought by plastics were equivalent to 1.
7 billion tons of carbon dioxide, and by 2050 it is expected to reach 6.
5 billion tons, which is equivalent to 15% of the global carbon budget at that time
.
The report calls on people to immediately reduce the use of plastics, transform the "plastic economy" model, and establish a soundThe whole-process monitoring system for the circulation of plastic products

Monitoring equipment to solve the problem of marine garbage pollution

At present, all localities are promoting the treatment of marine garbage through environmental awareness propaganda, and at the same time monitoring and predicting marine garbage pollution through various methods
.
In the "Marine Garbage Monitoring, Evaluation and Control Technology Commercialization Research Project" completed by the Xiamen Municipal Bureau of Oceans and Fisheries, it not only monitors and analyzes the current status of marine garbage and microplastic pollution in Xiamen Bay, but also establishes a method for monitoring marine garbage in Gulf cities.
The system has carried out the research on the prediction and prediction of the drift trajectory of the Jiulong River into the sea, and developed the Xiamen marine garbage GIS auxiliary decision-making system to predict the drift time, drift path, drift location and distribution area of the Jiulong River into the sea, realizing daily Prediction and forecast of the drift trajectory and distribution area of garbage entering the sea in the basin

.
The improvement of monitoring work has made ocean governance even more powerful.
However, in order to further improve the prevention and control of marine plastic waste in China and actively respond to changes in the international ocean governance situation, further breakthroughs are needed in marine monitoring
.
The National Marine Monitoring Center pointed out that at present, there are still three problems in marine monitoring

.
To this end, China is studying the establishment of marine garbage and microplastics monitoring technology methods that are in line with international standards, strengthening the monitoring of marine plastic garbage, and providing scientific data support for the country's marine plastic garbage management and response work
.
At the same time, some people in the industry pointed out that by estimating the flux of imported plastic waste in rivers, sewage outlets, marine aquaculture and fishing, and offshore exploration and development activities, we can gain in-depth understanding of the sources of marine waste and microplastics generated by different coastal and marine activities.
The formulation of marine plastic waste and microplastics control measures supports the simulation and analysis of the migration path and spread range of marine plastic waste to promote the treatment of marine waste

The complexity, variety and hazards of marine debris determine that this is not a task that can be completed in a short period of time.
For the monitoring instrument industry, which is an important data support for marine debris management, it must also actively assume its own responsibilities.
Play an important guiding role in the garbage management work to help the marine environment management work

"Smog" in the ocean, scientific instruments identify micro-plastic pollution
"Smog" in the ocean, scientific instruments identify micro-plastic pollution Regarding plastics seen in the deep sea, one good way to effectively control the plastics is to develop related garbage recycling technologies.
But when it comes to plastics in the ocean, it is not just about recycling
.
At present, among the marine plastic pollution problems that plague us, there is a type of microplastic pollution, which is called the "haze" in the ocean
.
As the "micro" in the name describes, one of the characteristics of this type of plastic is the extremely small particle size, which is not easy to be directly observed, difficult to recycle, and the huge specific surface area will attach more viruses
.
And more importantly, this feature makes it easier for him to destroy the living conditions of creatures in the marine ecology, threaten biological life, destroy the marine biological chain, and then bring harm to humans

.
According to incomplete statistics, currently known sources of microplastic pollution include cosmetics, detergents, microscopes, agricultural tools, paints, etc.
, most of which flow to the sea through sewers
.
Of course, in the face of the actual situation of microplastics pollution, humans will naturally not wait to die.
On the one hand, as an important part of marine environmental governance, marine water quality monitoring has included microplastics pollution as a regular indicator.
With the help of infrared spectroscopy, microplastics in the ocean The plastic will have nowhere to hide, exposed to the golden eyes of the instrument
