For the purpose of this document, the terms and definitions defined in the Recommendations on the Transport of Dangerous Goods Model Regulations and the following apply. 3.1
acute aquatic toxicity
Acute aquatic toxicity
The inherent property of a substance to cause harm to organisms exposed to it in the short term. 3.2
chronic aquatic toxicityThe potential or actual property of a substance to produce harmful effects on aquatic organisms during exposure periods relevant to the life cycle of the organism. 3.3
bioaccumulation
The net result of the uptake, transformation and elimination of a substance by an organism through all exposure pathways (air, water, sediment/soil and food, etc.). SN/T1828.17—2013
degradation
The decomposition of organic molecules into smaller molecules and finally into carbon dioxide, water and salts. 3.5
no observed effect concentration
no observed effect concentration; NOECThe test concentration is just below the lowest measured concentration that produces a statistically significant adverse effect. 3.6
Median lethal dose 50%, LDso is the dose that causes 50% (half) death of a group of test organisms. 3.7
Median lethal concentration, LCso is the concentration that causes 50% (half) death of a group of test organisms. 3.8
The concentration that causes % of organisms in a group of test organisms to show a certain observed effect. 3.9
Marine pollutantsmarinepollutant
Includes liquid or solid substances that pollute the aquatic environment, as well as mixtures of such substances. The basic elements for the classification of marine pollutants include acute aquatic toxicity, chronic aquatic toxicity, actual or potential bioaccumulation capacity, and organic chemicals (biological or abiotic) degradation capacity. 3.10
Biochemical oxygen demand, BOD. It is 5d biochemical oxygen demand. 3.11
Chemical oxygen demand.
4 General requirements
Warning—Due to their inherent hazards, testing laboratories should pay special attention to the health and safety requirements required by regulations. 4.1 Laboratory requirements
In general, toxicity data for freshwater and marine species can be considered as equivalent data, preferably data obtained using OECD test guidelines or equivalent data obtained according to the principles of Good Laboratory Practice (GLP). In the event that such data are not available, classification should be based on the most reliable data available.
4.2 Data requirements
4.2.1 Acute aquatic toxicity data
Acute aquatic toxicity data should meet the following requirements: a) 96h LCsa for fish (GB/T 21281 or equivalent test); b) 48h ECso test for crustaceans (GB/T 21830 or equivalent test), and/or; ce) 72h or 96h ECso test for seaweed (GB/T 21805 or equivalent test). These species can be considered as surrogate species for all aquatic organisms. Data on other species, such as duckweed, may also be considered if the test methods are appropriate.
4.2.2 Chronic toxicity Aquatic toxicity data
Chronic toxicity Aquatic toxicity data should meet the following requirements: data obtained from early life stages of fish GB/T 21854a)
b) data obtained from reproduction of Daphnia GB/T 21828, and; c) data obtained from inhibition of algal growth GB/T 21805. SN/T 1828.17—2013
Other valid and internationally accepted tests may also be used. "No Observed Effect Concentrations" (NOECs) or other equivalent EC4.2.3 Bioaccumulation Capacity
The bioaccumulation capacity is usually determined by the octanol partition coefficient, usually reported as logK according to GB/T21853 or GB/T21852. Although it also reflects the bioaccumulation capacity, the "bioconcentration factor" (BCF) determined by experiment is a better method and should be used in preference when possible. The bioconcentration factor should be determined in accordance with GB/T21800. 4.2.4 Environmental Degradation
Environmental degradation can be biological or abiotic (such as hydrolysis). Biodegradability tests (GB/T21801, GB/T21802, GB/T21803, GB/T21831. GB/T21856, GB/T21857) can be used to determine whether it is readily biodegradable. A pass level in the test can be considered to be rapidly degradable in most environments. Since this is a freshwater test, the results of GB/T21815.1 are also included, which is more suitable for marine environments. In the absence of such data, BOD (5d) / COD ≥ 0.5 is also considered to indicate rapid degradation.
4.2.5 Rapid environmental degradation
, reaching the following degradation levels!
4.2.5.1 In a 28-day rapid biodegradation study a) Based on tests on dissolved organic carbon: 70%: b) Based on tests measuring oxygen consumption or carbon dioxide production: 60% Theoretical peak: The above biodegradation level should be reached within 10 days after the start of degradation, when the start of degradation is when 10% of the substance has been degraded; unless the substance is a mixture with multiple components of similar structure. In this case, the 10-day window condition can be abandoned and the pass level can be applied at 28 days.
4.2.5.2 Where only BOD and COD data are available, BODs/COD ≥ 0.54.2.5.3 Where other credible scientific evidence is available to show that the substance or mixture can be degraded by more than 70% in the aquatic environment (through biotic and/or abiotic pathways) within 28 days. 5 Classification categories and standards
Categories and standards for substance classification
Substances meet the acute, chronic, or class II categories based on their aquatic toxicity hazards. 5.1.2 Acute (short-term) aquatic hazards shall meet the following requirements: a) 96h, LCsa (fish) ≤ 1mg/L; and/or b) 48h, ECso (crustacea) ≤ 1mg/L; and/or c) 72 or 96h, ECso (algae or other aquatic plants) ≤ 1mg/L. 5.1.3 Long-term aquatic hazards should meet the following requirements:
a) Non-rapidly degradable substances with sufficient chronic toxicity data 1) Chronic Category I:
SN/T1828.17—2013
Chronic NOEC or EC. (fish) ≤0.1mg/L: and/or chronic NOEC or EC. (crustacea) ≤0.1mg/L: and/or chronic NOEC or EC, (algae or other aquatic plants) ≤0.1mg/L 2) Chronic Category II:
-Chronic NOEC or EC (fish) ≤1mg/L: and/or chronic NOEC or EC (crustacea) ≤1mg/L; and/or chronic NOEC or EC. (algae or other aquatic plants) ≤1mg/L. b) Rapidly degradable substances with sufficient chronic toxicity data 1) Chronic Category I:
Chronic NOEC or EC (fish) ≤ 0.01 mg/L; and/or Chronic NOEC or EC, (crustacea) ≤ 0.01 mg/L: and/or Chronic NOEC or EC. (algae or other aquatic plants) ≤ 0.01 mg/L. 2) Chronic Category II:

-96h, LCso (fish)>1 but ≤10mg/L and/or -48h, ECso (crustacea)>1 but ≤10mg/L; and/or -72h or 96h, ECso (algae or other aquatic plants)>1 but ≤10mg/L and/or -72h or 96h, ECso (algae or other aquatic plants)>1 but ≤10mg/L and/or a non-rapidly degradable substance and/or experimentally determined BCF≥500 (or lack of data for logKw≥4). NOTE 1: 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 may also be considered, however, they should be provided as equivalent substances and test endpoints. NOTE 2: When classifying a substance as acute I and/or chronic I, also indicate the appropriate M factor to obtain the sum. NOTE 3: When the reduction in algal toxicity ErC[=ECa (growth rate) is greater than 100 times that of the next most sensitive species, and classification is based solely on this result, consider whether this toxicity data can be replaced by equivalent plant toxicity data. If it can be demonstrated that this is not the case, professional judgement is used. Classification is based on ErCso data. In the absence of ECse data, classification is based on the lowest available ECso NOTE 4: 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 is considered to be non-rapidly degradable. NOTE 5: Bioaccumulation potential is based on an experimentally derived BCF ≥ 500, or, in the absence of data on logKw ≥ 4. logKw data is better than the estimated value, and BCF data is better than logK value.
