Alcance y aplicabilidad

This standard specifies the terms, definitions, classification criteria, decision logic, and labeling for chemicals hazardous to the aquatic environment. It is applicable to the classification and labeling of such chemicals according to the UN GHS (4th revised edition). This standard is mandatory for chemical manufacturers and importers dealing with aquatic environmental hazards. It replaces the previous standard GB 20602-2006.

Requisitos técnicos

The standard establishes the basic elements for classifying chemicals hazardous to the aquatic environment, including acute aquatic toxicity, chronic aquatic toxicity, bioaccumulation potential, and degradation of organic compounds. It emphasizes the use of data derived from internationally recognized test methods or equivalent national standards. Manufacturers must prioritize high-quality data for accurate hazard classification. For substance classification, the standard defines three acute categories and four chronic categories. The acute classification is based solely on acute toxicity data, while chronic classification uses a tiered approach, considering chronic toxicity data, or a combination of acute toxicity and environmental fate data (degradability and bioaccumulation). A "safety net" classification (Chronic Category 4) is provided for substances that do not meet formal criteria but still raise concerns. For mixtures, the standard outlines a tiered classification approach. This includes using data from tested mixtures, applying bridging principles, or utilizing the summation method and additivity formulas based on the classified components' concentrations. Highly toxic components require the application of multiplying factors (M-factors) to ensure accurate mixture classification. Labeling requirements mandate the use of specific pictograms, signal words, and hazard statements corresponding to the assigned hazard categories. The standard aligns its labeling elements with the UN Recommendations on the Transport of Dangerous Goods. It also details precautionary statements to minimize environmental exposure.

Métodos de ensayo

Acute aquatic toxicity tests: Fish 96h LC50, Crustacean 48h EC50, Algae 72/96h ErC50. Chronic aquatic toxicity tests: Fish early life stage, Daphnia reproduction, Algae growth inhibition. Bioaccumulation tests: Determined via Bioconcentration Factor (BCF) or octanol-water partition coefficient (log Kow). Degradability tests: Ready biodegradability tests (e.g., DOC die-away, CO2 evolution) and BOD/COD ratio.

Preguntas frecuentes

What products are regulated under GB 30000.28-2013?

It applies to all chemicals and mixtures that pose a hazard to the aquatic environment, requiring them to be classified and labeled according to GHS principles before entering the Chinese market.

Are there any updates from the previous version of this standard?

Yes, it replaces GB 20602-2006. Key updates include modified terminology (e.g., "bioconcentration" instead of "bioaccumulation" in specific contexts), the addition of chronic toxicity additivity formulas for mixtures, and updated decision logic flowcharts.

How does GB 30000.28-2013 align with international standards?

The technical content is consistent with the 4th revised edition of the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
