On the 19th, it was learned from the China Ocean Association that the exploratory work on the fourth segment of the 49th cruise of China Ocean recently ended. The scientific expedition team carried out surveys on marine microplastics at five stations in this segment, which is also the first time in China. The southwest Indian Ocean conducts surveys of marine micro-plastics.
Focusing on international concerns about micro-plastic pollution and other marine environmental issues, China's first investigation in the Indian Ocean will help promote the integration of marine micro-plastics monitoring and marine environmental governance into global marine environmental monitoring and international governance. Ni Jianyu, chief scientist of the four-segment segment said.
Marine microplastics is called 'PM2.5 in the ocean'. As microplastics can adsorb persistent organic pollutants and heavy metals, and can be eaten by marine organisms such as birds and fish, benthic animals, microplastics have become international Marine ecology and environmental science research hotspots.
In 2016, the State Oceanic Administration initiated the monitoring of offshore micro-plastics, and later expanded the scope to ocean and polar regions. The micro-plastic survey will help our scientists understand the distribution of marine micro-plastics in the southwest Indian Ocean and assess micro-plastic contamination in the region. To provide important data.
As a responsible big country, the scope of China’s oceanic research is constantly deepening, especially in the close tracking of global hotspots and cutting-edge issues in different sea areas, and made due contributions. ' Ni Jianyu said.
