5.1 Overview
GB29919—2013
5.1.1 Environmentally hazardous substances include: liquids or solids that pollute the aquatic environment and solutions and mixtures of these substances (such as preparations and wastes).
2 The aquatic environment can be considered as aquatic organisms and aquatic ecosystems living in water. Therefore, the basis for identifying hazards is the aquatic toxicity of the substance 5.1.2
or mixture, although it may change due to degradation or bioaccumulation. 5.1.3 Although the following classification procedures are intended to apply to all substances and mixtures, in some cases, such as metals or poorly soluble inorganic compounds, special guidance is required. 5.2
Data requirements
5.2.1 Basic elements for the classification of substances for environmental hazards (aquatic environment): acute aquatic toxicity;
chronic aquatic toxicity;
actual or potential bioaccumulation; and
degradability of organic chemicals (biotic or abiotic). d)
Although data obtained from internationally harmonized test methods are preferred, in practice data obtained from domestic methods may also be used as long as they are considered equivalent. In general, toxicity data for freshwater and marine species can be considered equivalent data. Preferably, data obtained using OECD test guidelines or equivalent data obtained in accordance with the principles of Good Laboratory Practice (GLP) are used. Where such data are unavailable, classification should be based on the best available data. 5.2.3 Acute aquatic toxicity should be determined by the 96h LC5° test for fish (GB/T 21281 or equivalent test), the 48h EC5c test for crustaceans (GB/T 21830 or equivalent test), and/or the 72h or 96h ECsc test for algae (GB/T 21805 or equivalent test). These species may be considered as surrogate species for all aquatic organisms. Data on other species, such as duckweed, may also be considered if the test method is appropriate.
5.2.4 The available data for chronic toxicity are less than those for acute toxicity, and the complete test procedures are not standardized enough. Data obtained in accordance with GB/T 21854 or GB/T 21828 and GB/T 21805 may be accepted. Other valid and internationally accepted tests may also be used. "No Observed Effect Concentrations" (NOECs) or other equivalent ECs should be used. 5.2.5 The ability to bioaccumulate is usually determined by the octanol solution partition coefficient, usually reported as lgK derived in accordance with GB/T21853 or GB/T21852. Although it also reflects the ability to bioaccumulate, the "bioconcentration factor" (BCF) determined by the experiment is a better method and should be used preferentially when possible. The bioconcentration factor should be determined in accordance with GB/T21800. 5.2.6 Environmental degradation can be either biological or abiotic (such as hydrolysis), and the standards used reflect this fact. Rapid biodegradation is most simply defined using the OECD biodegradability tests (GB/T21801, GB/T21802, GB/T21803, GB/T21831, GB/T21856, GB/T21857). Passing levels in these tests are considered to be rapidly degradable in most aquatic environments. Since these are freshwater tests, the results of GB/T21815.1 are also included, which is more suitable for marine environments. In the absence of such data, BOD(5d)/CO)D≥0.5 is also considered to indicate rapid degradation. Abiotic degradation, such as hydrolysis, primary degradation (abiotic and biotic), degradation in non-aquatic media, and proven rapid degradation in the environment can all be considered in determining rapid degradability. 5.2.7 A substance can be considered to be rapidly degradable in the environment if it meets the following criteria: a) In a 28-day rapid biodegradation study, the following degradation levels are achieved: 1) Based on tests on dissolved organic carbon: 70% 2) Based on tests measuring oxygen consumption or carbon dioxide production: 60% Theoretical peak: The above biodegradation levels should be achieved within 10 days after the start of degradation. The start of degradation is when 10% of the substance has been degraded; unless the substance is a mixture with multiple structurally similar components. In this case, the 10-day window condition can be waived and the pass level applied at 28 days.
b) In cases where only B(D) and CO(D) data are available, B(D) (5d) / C(D) is ≥ 0.5; or
If other credible scientific evidence is available that the substance or mixture can be degraded by more than 70% in the aquatic environment (by biotic and) or abiotic pathways within 28 days. 5.3 Classification types and standards of substances
According to Table 1, substances that meet the classification criteria of acute 1, chronic 1 or chronic 2 should be classified as "environmentally hazardous substances (aquatic environment)". Table 1 specifies the classification. Table 2 explains the classification scheme for substances that are hazardous to the aquatic environment.

Provide equivalent substances and test endpoints that they represent. bWhen classifying a substance as Acute 1 and/or Chronic 1, it is necessary to indicate at the same time the appropriate M factor to obtain the summed means. When the reduction in algal toxicity ErCs [ECs (growth rate)] is greater than 100 times that of the next most sensitive species and classification is based solely on this result, it should be considered whether the toxicity data can be replaced by equivalent plant toxicity data. If it can be demonstrated that this is not the case, professional judgement should be used. Classification should be based on ErCn data. In the absence of ECsn data, classification should be based on the lowest available ECse. Lack of rapid degradation data refers to the lack of biodegradability and other rapid degradation data. When no degradation data, other empirical or predictive data are available, the substance should be considered as non-rapidly degradable. Bioaccumulation potential, based on experimentally derived BCF ≥ 500. Or. Lack of IgK ≥ 4 data. IgK data are better than the estimated value. BCF data are better than the IgK value.

Fish, crustaceans and algae are tested as alternatives, covering all trophic levels and taxa, and the test methods are highly standardized. Data from other organisms can also be considered, but. Provide equivalent substances and test endpoints that they represent. bWhen classifying a substance as Acute 1 and/or Chronic 1, it is necessary to indicate at the same time the appropriate M factor to obtain the summed means. When the reduction in algal toxicity ErCs [ECs (growth rate)] is greater than 100 times that of the next most sensitive species, and classification is based solely on this result, it should be considered whether the toxicity data can be replaced by equivalent plant toxicity data. If it can be demonstrated that this is not the case, professional judgement should be used. Classification should be based on ErCn data. In the absence of ECsn data, classification should be based on the lowest available ECse. Lack of rapid degradation data refers to the lack of biodegradability and other rapid degradation data. When no degradation data, other empirical or predictive data are available, the substance should be considered as non-rapidly degradable. Bioaccumulation potential, based on experimentally derived BCF ≥ 500. Or. Lack of IgK ≥ 4 data. IgK data are better than the estimated value. BCF data are better than IgK values.
