[Research and application progresses on rice water quality (RICEWQ)model.]

Area of Science:

• Environmental Science
• Agricultural Science
• Ecotoxicology

Background:

• Rice cultivation frequently uses pesticides, posing pollution risks to surrounding water bodies.
• Rising costs of pesticide monitoring necessitate reliable mathematical models for registration.
• The RICEWQ model is a key tool for pesticide exposure assessment in European paddy fields.

Purpose of the Study:

• To review the RICEWQ model's structure, processes, and application in pesticide exposure assessment.
• To summarize global and domestic research progress on the RICEWQ model.
• To promote the adoption and provide reference for the RICEWQ model in China.

Main Methods:

• Review of existing literature on the RICEWQ model.
• Analysis of the model's system structure, pesticide fate processes, and data inputs/outputs.
• Summary of research on RICEWQ model application in China and internationally.

Main Results:

• The RICEWQ model effectively predicts pesticide concentrations in paddy fields and water.
• The model has been preliminarily applied and shows potential for wider use in China.
• A comprehensive understanding of the model's components and research landscape is provided.

Conclusions:

• The RICEWQ model is valuable for assessing pesticide environmental risks in rice production.
• Further application of the RICEWQ model in China can enhance pesticide registration and environmental management.
• This review serves as a foundational reference for future research and implementation.
