적용 범위

This standard applies to both marine and freshwater fishery water areas, including spawning grounds, foraging areas, wintering grounds, migration channels, and aquaculture zones. It is specifically designed to prevent and control water pollution to ensure the normal growth, reproduction, and quality of aquatic products. It is mandatory for all enterprises and operators discharging wastewater into or near these sensitive aquatic environments.

기술 요구 사항

The standard specifies comprehensive physical, chemical, and biological requirements for fishery water quality. It mandates that water must not cause abnormal color, odor, or taste in aquatic organisms, and strictly prohibits the presence of visible oil films or excessive floating matter. Key parameters regulated include pH value, dissolved oxygen, and biochemical oxygen demand (BOD5), with specific considerations for ice-covered periods. The standard establishes strict maximum allowable concentration limits for a wide range of toxic substances. This includes heavy metals such as mercury, cadmium, lead, and chromium, as well as hazardous chemicals like cyanides, sulfides, and volatile phenols. Any single parameter exceeding its specified limit indicates that the water cannot safely support normal aquatic life. Additionally, the standard sets stringent limits for various pesticides and organic pollutants, including DDT, malathion, and pentachlorophenol sodium. It also regulates non-ionic ammonia and total coliform bacteria, with stricter limits applied specifically to shellfish aquaculture waters. Supplementary appendices are provided for the conversion of total ammonia to non-ionic ammonia concentrations based on temperature and pH.

시험 방법

The standard outlines specific analytical methods for monitoring water quality, extensively referencing other national standards (e.g., GB 5750, GB 7468). Testing procedures include the glass electrode method for pH, the iodometric method for dissolved oxygen, and atomic absorption spectrophotometry for heavy metals like copper, zinc, lead, and cadmium. Monitoring must be conducted by fishery environmental monitoring stations organized by local fishery supervision departments.

자주 묻는 질문

What types of water bodies are regulated under GB 11607-89?

The standard applies to both marine and freshwater fisheries waters, including spawning grounds, foraging areas, wintering grounds, migration channels, and aquaculture zones for fish, shrimp, shellfish, and algae.

Is GB 11607-89 a mandatory standard for wastewater discharge?

Yes, the standard is mandatory. It is enforced by fishery supervision and management departments. Local governments can even establish stricter local pollutant discharge standards if national requirements are insufficient to protect local fisheries.

Does GB 11607-89 specify limits for heavy metals and pesticides?

The standard sets specific limits for heavy metals (such as mercury, cadmium, lead, and chromium), pesticides (like DDT and malathion), volatile phenols, and petroleum. It also regulates physical parameters like pH value and dissolved oxygen.

The summary above provides a high-level overview of GB 11607-89.
