Sinochem News On October 20, the basic science section of the National Natural Science Foundation of China launched the special project of "Environmental Chemical Behavior and Effects of Micro plastics". The duration of the project is 4 years, and the funding intensity is 3 million yuan for each project.

The project aims to carry out systematic research on detection methods, interface behavior, migration and transformation, etc. in response to the national major needs and key scientific issues of micro plastic pollution prevention and control, lead the frontier research of basic science in the field of micro plastics, and provide scientific basis and theoretical basis for protecting the ecological environment and human health.

The project supports four directions: first, new methods for detecting microplastics in the environment and pollution characteristics, including research on the separation and enrichment technology of microplastics in complex environments and biological matrices, development of identification, highly sensitive and rapid detection methods and traceability technology of microplastics, especially nanomaterials; The second is the interface chemical behavior of microplastics in the environment, including studying the formation mechanism and interface behavior of microplastics in the environment, revealing their physical, chemical, biological transformation processes and molecular mechanisms, and exploring the release process of toxic substances in microplastics under environmental conditions and the interaction mechanism with environmental media and co existing pollutants; Third, the toxicity and health effects of micro plastics in the environment; The fourth is the reduction and control principle of micro plastics in the environment.
