Introduction
In-depth analysis of GB/T 34666.1—2017 Technical Specification for the Compilation of Water Quality Benchmark Data
| Standard Dimensions | Content Overview | Comparative Analysis |
|---|---|---|
| Scope and Applicability | The specification is applicable to the compilation of water quality benchmark data, and other medium environmental benchmark data can be used for reference. | Compared with HJ/T 91, the integration requirements for sediment and aquatic toxicity data are added. |
| Data Source and Collection | Including multi-channel data such as public literature and monitoring reports, emphasizing data integrity and consistency. | In terms of data integrity, it is more stringent than SL 249 and requires more watershed classifications. |
| Compilation process and quality control | From sampling point information to sample analysis, each step has detailed specifications and quality inspection mechanisms. | The data filling format is more standardized, and electronic spreadsheet templates and computer program control are introduced. |
Standard formulation background and technology evolution analysis
The formulation of technical specifications for the compilation of water quality benchmark data is mainly based on the country's demand for improving water environment quality. With the acceleration of industrialization, water pollution problems are becoming increasingly serious. Establishing a scientific data compilation system has become an important basis for formulating environmental policies.
From the perspective of technological evolution, GB/T 34666.1-2017 combines advanced domestic and foreign experience, especially in the diversification of data sources and the automation of quality control. For example, in the sample analysis stage, it is required to record the names of the main instruments (such as atomic absorption spectrometer) and their detection limits in detail to ensure the traceability of the data.
Implementation suggestions
1. Data collection and management:It is recommended to use a structured database to store pollutant content data, and at the same time establish a metadata tag system (such as the name of the first-level watershed, sampling time, etc.) to facilitate subsequent analysis and visual display.
2. Quality control measures:It is recommended to introduce automated data verification tools to detect the standardization and completeness of data filling online. In particular, in terms of concentration values and coordinate filling, strictly abide by the relevant provisions of GB/T15834 and GB/T3102.1.
3. Standard promotion and training: In view of the high degree of professionalism involved in this standard, it is recommended that environmental protection departments, monitoring agencies and scientific research institutions jointly carry out standard promotion activities to ensure that relevant personnel are familiar with the basic requirements and operating procedures for data compilation.
