HC Plastics News: The ocean is open, and the city of Xiamen is also open. This is evident in the management of marine debris in Xiamen.
In order to improve the local governance system, Xiamen can break out of Xiamen Bay, focus on the future, focus on cooperation and exchanges at home and abroad, and launch many powerful initiatives leading the country.
In this issue of the "No. Reader", we went to the "Ecotoxic Toxicology Aquarium Hall" of the Ocean III to learn about a small fish with great ability - Qinglan.
Many people in Xiamen may not know that there is a very inconspicuous small bungalow next to the three whale dolphins on the university road, which has thousands of small and inconspicuous transparent fish.
It is called barley, the individual is small, the body length of the adult fish is generally only 3-4 cm, less than a bean sprout size.
Researchers at Ocean III said that it carries the burden of exploring global marine microplastic waste management research.
Known as "the white mouse in the water"
How do these inconspicuous little fishes relate to the global marine ecology problem?
“They are actually 'white mice in the water'. We hope to find out the effects of micro-plastics on marine life through experiments with these fishes, and look forward to establishing corresponding standards.†Chen Yizhe, Marine Science and Environmental Monitoring Technology Laboratory, Oceanic Institute The doctor explained.
On the wall of the humble little cottage, there is a sign: "Ecological Toxicology Aquarium". Although it is called the Aquarium, more accurately, it is actually a laboratory. The research on the influence of micro-plastics on fish has been carried out here for more than a year.
Microplastics, usually plastic particles with a particle size of less than 5 mm, are also visually compared to "PM2.5" in the ocean, and are currently a hot topic in marine ecological protection. In 2015, micro-plastic pollution was listed as the second-largest scientific issue in the field of environmental and ecological science research, and it is considered to be a major hidden danger affecting the marine ecological environment and even harming human health in the future.
It is understood that Xiamen is currently conducting research on the impact standards of micro-plastics on marine organisms, as well as monitoring standards for the characteristics of Xiamen Bay.
“Xiamen considers not only its own future problems.†Chen said that in the management of micro-plastic waste, Xiamen is first in China, and their research results will be monitored in the future for micro-plastics in other Gulf cities at home and abroad. Great reference.
Observing data through microplastics
According to reports, this humble little fish is rarely asked on weekdays. Unlike the coral restoration museum, which is home to tropical fish and is often visited by citizens, it feels very quiet and peaceful.
The Morning News reporter saw at the scene that the room here was emitting green and green light. Dozens of glass fish tanks were stacked on the wall layer by layer. The room temperature was maintained at around 25 °C throughout the year. The LED lights provided more than ten hours of illumination. .
The fish that swim in the glass jar are small and transparent. They don't look closely, and they can't even see that there are fish swimming inside. The only difference that can be seen in these dozens of fish tanks is the label attached to it, showing the different hatching times of the various batches of fish, as well as the micro-plastics of different density and particle size in seawater. “All other environmental factors are the same and the same,†the researchers said, in order to ensure that the observed data is due to changes in microplastics.
According to reports, this experiment needs more data, and the fish will stay here for a long time.
Although there is no colorful appearance, but the contribution is huge and the significance is extraordinary, these little fish should be thanked. The next time the citizens visit the three whale dolphins in the ocean, they may also visit the Ecotoxicology Aquarium.

Xiamen marine waste management results are fruitful
Xiamen has been committed to the management of sea drifting waste. After years of continuous efforts, it has achieved many successful experiences.
This year, Xiamen has also established a long-term mechanism for the prevention and control of sea drifting garbage. To this end, the Municipal Sea Drift Garbage Emergency Disposal Coordination Group was established to formulate the “Xiamen Bay Sea Drift Garbage Emergency Disposal Plan†to deal with extreme weather such as typhoon and heavy rain. The problem of emergency disposal of sea drifting garbage in the case. As a reinforcement, the troops stationed in Xiamen are also included in the sea drift garbage emergency disposal system.
Next, Xiamen will continue to improve the sea drift garbage control system, considering that Xiamen Bay sea drift garbage mainly comes from Jiulong River, and Xiamen next plans to be in front of three dams such as Beixi, Xixi and Nanxi in Longhai section of Jiulong River. Carry out garbage interception, transshipment and disposal, and hope to solve the problem of drifting garbage in Xiamen Bay from the source.
Under the leadership of the Municipal Ocean and Fisheries Bureau and the support of the central government, Xiamen also carried out research on the project “Human Waste Monitoring, Assessment and Prevention Technology Operational Research and Demonstration and Applicationâ€, among which many studies are in the forefront of the country.
Sea drifting garbage is not only a problem in Xiamen, but also a problem in China, but a problem in the world.
In the treatment of sea drift garbage, Xiamen pays attention to cooperation with other cities at home and abroad. In 2016, Xiamen established a “partner city†relationship with the city of San Francisco in the United States. Based on the actual situation of Xiamen, the “China-US Marine Waste Prevention and Control Xiamen-San Francisco “Partner City†Cooperation Implementation Plan was formulated.
Just this weekend (November 4th), the "APEC Marine Waste Management International Symposium", one of the 2017 Xiamen International Ocean Week events, will be held in Xiamen. Through the seminar, Xiamen will exchange marine waste management best practices with coastal cities in Asia and the Pacific to provide advice on the solution of marine debris in the APEC region.
Xiamen takes the lead in realizing the forecast of seaborne garbage
What is the trajectory of sea drifting garbage today? Which sea areas will have more garbage? In July this year, Xiamen implemented the first forecast of the trajectory of the inflow of seawater into the sea in China.
It is understood that the project is supported by Xiamen Ocean and Earth Institute of Xiamen University, based on the “Landscape Monitoring, Assessment and Prevention Technology Business Research†project in Xiamen, based on the existing wind field in the Taiwan Strait, based on the three-dimensional temperature, salt and flow models. The multi-grid nesting technology establishes a refined forecasting system in Xiamen Bay, and then develops a sea drift garbage trail prediction system.
Since the release of the forecast, the research unit has been comparing with the actual situation, constantly correcting the forecasting parameters and improving the accuracy of the forecasting. Subsequent repeated verifications, as well as feedback from marine salvage units, indicate that the prediction of sea drift garbage trajectory can basically accurately reflect the trend of sea drift garbage, provide accurate guidance for the cleanup work of marine sanitation units, and provide for the treatment of Xiamen sea drift garbage.
