This part applies to the compilation of water quality criteria data. The compilation of environmental criteria data for other media may refer to this standard. 2 Normative references The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) is applicable to this standard. GB/T 3102.11 Mathematical signs and symbols for use in the physical sciences and technology GB/T 15834 General rules for punctuation GB/T 15835 General rules for writing numerals in publications GB/T 19378 Nomenclature and codes for pesticide for formulations GB/T 21605 Test method of acute inhalation toxicity for chemicals GB/T 21800 Testing of chemicals Bioconcentration - Flow-through fish test GB/T 21804 Chemicals - Test method of acute oral toxicity-fixed dosed procedure GB/T 21805 Chemicals - Alga growth inhibition test GB/T 21808 Testing of chemicals - Fish prolonged toxicity: 14-day study test GB/T 21813 Chemicals - Honeybees acute contact toxicity test 5 Principles of data compilation 5.1 Completeness All the toxicity data of aquatic organisms in the data shall be collected completely, without redundancy or omission. The required information marked shall be filled in completely. 5.2 Consistency The compiled data and corresponding description information are consistent with the content of the original data. It meets the consistency of concept, format value range. 5.3 Standardization Carry out standardized data compilation and processing, in strict accordance with the basic requirements and content of data compilation. 6 Data compilation content 6.1 Basic requirements for data compilation The basic requirements for data compilation include: a) Each aquatic toxicity data contains six aspects of information: chemical substance information, experimental biological information, experimental condition information, experimental result information, experimental matrix information, data source information. b) The main reference [6] collects the following data: the toxicity test data of living organisms; the toxic effect test data of organisms at the individual level (not a certain part of the organ, tissue or cell of the organism); the toxicity test data that has adverse effects on organisms; the toxicity test data that has beneficial effects on organisms (e.g., nutritional effects); the toxicity test data that describes the concentration, dose, or dosage of chemical poisons in the experimental environment; the toxicity test data of sediment that describes the concentration of the toxicant in water (overlying water or interstitial water); the toxicity test data that describes the exposure time of the toxic substance that produces a biological effect; 6.2 Contents of data compilation of chemical substance information The data items of chemical substance information and their filling requirements are as shown in Table 1. The required data items include: identification code, chemical substance name, chemical reagent purity, purity value, CAS number. Table 1 -- Data items of chemical substance information and their filling requirements Data item Filling requirements Identification code * Fill in the identification code of a piece of data. The specific requirements are as follows: a) It may, according to different chemical substance types, experimental biological classifications, compilation time, data sources, set the identification code of each piece of data; b) Each piece of data corresponds to a unique identification code Chemical substance name * Chinese name Fill in the Chinese and English names of the chemical substances, respectively. The specific requirements are as follows: a) If the experimental chemical substance is not directly added, BUT the experimental chemical substance is changed by the neutralization reaction or the addition of a salt, it shall carry out necessary processing, THEN, fill in the information of the chemical substance actually exposed by the experimental organism; b) If the chemical substance does not have a CAS number, OR the chemical substance has more than one CAS number, it shall check its molecular formula to get the chemical name; c) If the hydrate of a chemical substance is used in the data, fill in the hydrate name of the chemical substance in this data item; fill the information of its hydrate in the following data item English name CAS number * Fill in the CAS number of the chemical substance Classification of chemical substances Fill in the classification of the chemical substance, such as aluminum, chromium, DDT and its metabolites, polybrominated diphenyl ethers (PBDEs), etc. If a chemical substance belongs to multiple classifications, fill in all the classification names in the data items of chemical substance classification; separate them with commas Chemical reagent purity * Fill in the purity of the chemical reagent in the data. For example, analytical pure, chromatographic pure, etc. Purity value * Fill in the purity value of the experimental chemical reagent OR the percentage value of its active ingredient Chemical substance dosage form Fill in the chemical substance dosage form, such as oil, solution, particulate, powder, etc. Solvent Chinese name of solvent d) The usage of punctuation marks, in the data item of remarks, shall meet the requirements of GB/T 15834. Use a comma (,) to connect the comment content of the same information; use a semicolon (;) to separate the information which is listed item by item; use a colon (:) to connect the remark information of the corresponding data item; e) In the data item to fill the data value, fill in the average value, minimum value, maximum value, which are given in the data. The format of the expression method is: the average value (minimum value ~ maximum value); meanwhile in the corresponding remarks data item, it may supplement the confidence interval, confidence limit and range of the data value in the data. When the average value of the data does not fall within the range of the maximum and minimum values, OR within the confidence limit or the confidence interval described in the data, in the data item to fill the data value, it stills fills in the “average value (minimum value ~ maximum value)”; meanwhile in the remark data item, fill in "the confidence interval (or the confidence limit) is 'XX ~ XX' " or "the range is 'XX ~ XX' "; f) When filling in the endpoint data item, it shall pay attention to the endpoints LTxx, BMDxx, BMRSxx, ECxx, EDxx, ERxx, ETxx, ICxx, IDxx, LCxx, LDxx, LRxx, LTxx, with numerical values. Use the following form to represent the single digit: 0X (e.g., LC01, LC05); g) For the use of index, refer to the expression method of GB/T1.1, such as 3.02 × 10-8; f) The method of expressing the numerical range shall comply with the provisions of GB/T 3102.11, using the symbol "~" instead of "-". 7.3 Standardization of enumerated data items Except for some data item of remarks and numerical values, other data items can refer to the encoding table of ECOTOX (https://cfpub.epa.gov/ecotox/blackbox/help/codelist.pdf), to set the enumeration value of the corresponding data item, through the software. If the enumeration value of some data item is missing, during the data compilation process, the enumeration value of the corresponding data item can be added, after verification by relevant personnel. 7.4 Automation of data verification When the data compiler fills in relevant data items, computer programs are used to control the field width, data type, simple threshold check (see Table 7), AND ......
