GB/T 45196-2025 in English

1. Background and significance of standard formulation

GB/T 45196-2025 "Technical Guidelines for Environmental Quality Surveys in Agricultural Product Origin" is intended to standardize the environmental quality surveys in agricultural product origins in my country and ensure the quality and safety of agricultural products and the protection of the ecological environment. With the scale and industrialization of agricultural production, environmental pollution problems are becoming increasingly prominent, especially in agricultural product origins. The quality of environmental factors such as soil, irrigation water and atmospheric deposition directly affects the safety and quality of agricultural products.

2. Comparison of standard frameworks

3. Implementation suggestions

Case study: In a certain agricultural demonstration area, an environmental quality survey was conducted in accordance with the GB/T 45196-2025 standard. First, climate, soil and water quality data for the past ten years were collected, and then the irrigation water pollution type and air pollution type survey units were divided, and more than 3 monitoring points were deployed in each unit. Samples were collected and tested using the HJ/T 166 method, and it was finally found that the cadmium content in the irrigation water exceeded the standard. It is recommended to reduce the use of fertilizers and introduce purification technology.

4. Analysis of Technological Evolution

From the initial soil monitoring to the comprehensive investigation of irrigation water and atmospheric deposition, GB/T 45196-2025 reflects the technological progress of environmental quality assessment. In recent years, with the increasing attention to the quality and safety of agricultural products, the standard has introduced more advanced testing methods and data management technologies to ensure the scientificity and reliability of the survey results.
