An ecological risk assessment framework using the analytic hierarchy process was applied to microplastics in the Yangtze River Estuary, combining pressure, status, and response indicators to produce a composite risk index that identified moderate to high ecological risk in the estuary and adjacent marine areas.

Environmental
Microplastic (MP) pollution is ubiquitous in the terrestrial and marine environments, even in the air. However, ecological risk assessment studies of microplastics are scarce. In the present study, an ecological risk assessment model was built to evaluate the risks of microplastics in the Yangtze River Estuary and adjacent marine areas. A basic index database of the impacts of MP pollution on the ecosystem was constructed around three types of indices, namely, the pressure, status, and response indices. While the expert scoring method was used to determine the weights of these indices, in view of the complexity of the ecosystem in the Yangtze River Estuary, the fuzzy comprehensive evaluation method was used to evaluate its ecological risk. According to the model, microplastic pollution in the Yangtze River Estuary and adjacent marine areas was within a lower risk state, indicating that its risks for the marine ecosystem were still within a controllable range.
