In the following, the online help texts for all data entry fields provided with any Endpoint summary record for this IUCLID section are listed. As to whether and to what extent endpoint summaries should be prepared, refer to the relevant guidance for the respective chemical programme, e.g., the Technical Guidance Document (TGD) on preparing the Chemical Safety Report under REACH in its most recent version.
For technical guidance on how to manage Endpoint summary records, see How to manage Endpoint summary records in sections 4 - 10, respectively. For details on data types, see What data types are available for input fields and how are they used?.
Enter a full short description of the most relevant endpoint data. This includes in principle the summary information that is compiled e.g. in the OECD Full SIDS Summary format or other endpoint summary formats. Provide only the most relevant details, which could be, depending on the cases, the test guideline used, test organism and exposure duration. Normally no reliability score needs to be indicated as it can be assumed that the studies identified are valid (reliability score 1 or 2). If this is not the case (for instance if the reliability of a published study cannot be assigned or if several less valid studies are used for a weight of evidence analysis), the reliability indicators should be specified.
Also several key studies can be referenced as applicable. However, the characterisation of the endpoint data should be kept as concise as possible. Examples of what could be entered here are as follows:
- Melting point: 54.6-55.8 °C at 1,013 hPa
- Water solubility: completely miscible
- pH: 6.9 (80 mg/l water) at 20°C (OECD TG105)
- Oxidation reduction potential: no data available
- Phototransformation in air: T1/2 = 9.32 x 10-2 yr (sensitizer: OH radical) (AOP Win v 1.86)
- Biodegradation in water: screening tests: Not readily biodegradable: 0 - 8% (BOD) in 28 days, 0 - 1% (HPLC) in 28 days (OECD TG 301C)
- Short-term toxicity to fish:
LC50 (96h) < 100 mg/l for Pimephales promelas (OECD TG 203)
LC50 (48h) = 3.2 mg/l for Oryzias latipes (OECD TG 203)
- Acute toxicity:
Dermal: LD50: > 2,000 mg/kg for rat (limit test)
- Genetic toxicity:
In vitro:
Gene mutation (Bacterial reverse mutation assay / Ames test): S. typhimurium TA 100: positive with and without metabolic activation; TA 1535: positive without metabolic activation (equivalent to OECD TG 471)
The field(s) under this heading (if provided) can be optionally completed in order to specify the key parameter(s) that may subsequently be used in the chemical safety assessment, classification and labelling or other. In order to enable the use of any specific software, only a minimum number of structured and hence, searchable fields are provided, in many cases only one.
Key parameters are intended to condense the data summarised in field "Full short description of relevant endpoint data" to one single numeric value or concluding remark (e.g. negative / positive) chosen from a drop-down list. Where a numeric field is provided, only a clear value can be entered, that is, no range and no less than or greater than qualifiers. Conversion to a predefined unit as indicated in the field label (e.g. mg/L) may be required.
If the key value is no clear number, but a range or preceded by <, <=, >, or >=, you may either leave this field empty or make up a value you consider most appropriate for the intended subsequent purpose. The rationale for any user-derived values should be described in field "Discussion" for the sake of transparency. Some non-exhaustive examples of user-derived parameters are as follows:
- Aquatic short-term L(E)C50 >100 mg/L (e.g. because only tested up to water solubility of the substance): it may be appropriate to assume 100 mg/L as worst case value.
- Aquatic long-term LOEC 1 mg/L (>10 and <20% effect): calculate NOEC as LOEC/2 and enter 0.5 mg/L in the field for NOEC.
- Acute oral LD50 >2000 mg/kg b.w. (because no LD50 was achieved in a limit test): enter 2000 mg/kg b.w.
In this rich text field, describe the assessment you have made for the given endpoint. Provide the rationale for the choice of the key study(ies) and the choice of the key parameter that, according to your judgement, characterise the endpoint. This includes a discussion of the key information identified and in some instances of studies which are considered to be unreliable, but give critical results. A discussion as to why they were discarded in favour of other studies should then be included. Vice versa, a weight of evidence analysis based on less reliable data or use of published data, the reliability of which cannot be judged because of limited reporting, should be justified.
If several studies were identified to be relevant for the assessment, discuss possible reasons for differing results if any, e.g. differences in purity / impurities of the test substance used, differences in the methods and test conditions, etc.
In the following, the online help texts for all data entry fields provided with any Endpoint study record for this IUCLID section are listed. For sections 4 to 10, these guidance notes are completely based on the so-called OECD Harmonised Templates (see Rationale behind IUCLID Endpoint Study Records - OECD harmonised templates in chapter chapter D.4.7.1 What is an Endpoint study record?)
IUCLID per se does not prescribe how detailed the study summaries should be recorded. Refer to the relevant guidance for the respective chemical regulatory programme thereof.
For technical guidance on how to manage Endpoint study records, see chapter D.4.7 How to manage Endpoint study records in sections 4 - 13. For details on data types, see chapter D.4.5 What data types are available for input fields and how are they used?
Under this main heading, fields are subsumed for identifying the purpose of the record (e.g., "key study"), the type of result (e.g., "experimental study"), data waiving indication (if any), reliability indication, and flags for indicating the regulatory purpose envisaged and/or any confidentiality restrictions. This kind of data characterise the relevance of a study summary and are therefore displayed on top of each Endpoint Study Record. For detailed guidance, refer to chapter D.4.7.7.1 Administrative data.
Indicate the bibliographic reference of the study report or publication the study summary is based on. Always enter the primary reference in the first block of fields (i.e. Sort no. = 1), if there are more than one reference to be cited. Copy this block of fields for specifying any other references related to this record (e.g. report of a preliminary study or other documentation). If results of a study report have been published, indicate the full citation of that publication(s) in addition to the reference of the original study.
Table E.80. Field Descriptions
| Reference type | Indicate the type of reference, e.g. "Study report" or "Publication". Select "Other company data" to characterise any unpublished information from a company other than a study report. Select "Grey literature" for any other unpublished information or "other:" and specify. |
| Author(s) (or transferred reference) (Author) | For ease of sorting and searchability use following convention: Surname, Initial (Example 1: White D, Ruehl KJ, Borman SA & Little J. Example 2: Hartley M & Murray W (avoid unnecessary full-stops, commas)). If no individuals are cited as authors, enter name of company or organisation or "Anon." as appropriate. Note that the complete bibliographic reference may appear in this field after migration of unstructured data from existing databases. |
| Year | Enter year of study report or publication. For a study report this field should be completed to include it in any searches, regardless of whether the complete date is given in field "Report date". |
| Title | Include the title of the report. For publications, include the title of the article of a journal or article/chapter of a book (e.g. handbook). |
| Bibliographic source | Not relevant for any study report. For publications or any other literature source (grey literature) specify the following type of information: (i) Title of scientific journal or book (e.g. if handbook); (ii) Volume of journal; (iii) Editor, publisher, place of publication for books or articles in books; (iv) Pagination. Example 1 (journal): J. Agric. Food Chem. 38: 215-227 Example 2 (handbook): In: Lyman WJ (ed.) Handbook of chemical property estimation methods. Environmental behavior of organic compounds. McGraw-Hill Book Company 15.1-15.34, New York. |
| Testing laboratory | Either manually enter the name of the testing laboratory or select it from the picklist. In either case, editing is possible. |
| Report no. | Specify the report number allocated by the testing laboratory. Note that any company-specific study number should be included in the respective field. |
| Owner company | Either manually enter the identity of the company who owns the data or select it from the picklist. In either case, editing is possible. |
| Company study no. | Specify any company study no. if there is such a number and if it is different from the report no. of the testing laboratory. Otherwise leave field empty. |
| Report date | Specify the complete date of the study report, e.g. "2005-05-12" for 12 May 2005. Note that subfield "Year" should be completed in any case for sorting and searching purposes. |
Select appropriate indication for data access. Enter "Not applicable" if the summary consists of information that is commonly accessible such as guidance on safe use.
Indicate as appropriate. Note: "yes" should be selected only if "Data submitter is data owner" or "Data submitter has Letter of Access". Options "yes, but willing to share" or "yes, but not willing to share" may be relevant for specific regulatory programmes where the submitter is requested to indicate whether he is willing to share studies (e.g. with vertebrates).
In the supplementary remarks field, include an explanation as appropriate, i.e. justification for denial of sharing the corresponding study or refer to a document attached that provides justification (e.g. "for justification see attached document X")
A cross-reference can be included to indicate that the same study is recorded in another record. Indicate the respective chapter and record ID and enter relevant explanatory text. This may be useful if specific endpoints of a given study are described in another chapter (e.g. results on reproduction toxicity in case of a combined repeated dose / reproduction toxicity study) or if more than one experiment is described by the same study report, but included in separate records.
Check with the relevant guidance document whether all the methodology details must be repeated or whether a cross-reference to the same study in another chapter may suffice.
Note that any such cross-reference may become useless if a record is either printed or exchanged on its own.
Indicate according to which test guideline the study was conducted. If no test guideline was explicitly followed, but the methodology used is equivalent or similar to a specific guideline, you can indicate so in the "Qualifier" subfield preceding the field "Guideline".
Copy this block of fields for specifying more than one guideline (e.g. US EPA in addition to OECD guideline).
Table E.81. Field Descriptions
| Qualifier | Select appropriate qualifier, i.e. - "according to" (if a given test guideline was followed); - "equivalent or similar to" (if no test guideline was explicitly followed, but the methodology is equivalent or similar to a specific guideline); - "no guideline followed" (if none of above qualifiers apply. If so, fill in field "Principles of method if other than guideline"); - "no guideline available" (if so, fill in field "Principles of method if other than guideline"). - "no guideline required" (if so, fill in field "Principles of method if other than guideline"). |
| Guideline | Select the applicable test guideline, e.g. "OECD Guideline xxx". If the test guideline used is not listed, choose "other guideline:" and specify the test guideline in the related text field. In this text field, you can also enter any remarks as applicable, particularly: - To include any other title of the test guideline draft used, a subtitle, another version or update number and the year of update (For instance, different titles and/or numbers may exist for a given EU test guideline.); - To indicate if a the study was performed prior to the adoption of the test guideline specified; - To indicate if the methodology used was based on an extension of the test guideline specified. |
| Deviations from guideline (Deviations) | For robust study summaries or as requested by the regulatory programme, indicate if there are any deviations from the test guideline specified. If "yes" is selected, only briefly state relevant deviations in the supplementary remarks field (e.g. "other species used"); details should be described in the respective fields of the section MATERIALS AND METHODS. |
If no guideline was followed, include a description of the principles of the test protocol or estimated method used in the study. Details should be entered in appropriate distinct fields of section MATERIALS AND METHODS if available. Also provide a justification for using this method if appropriate.
If an estimation method was used (to be indicated in field "Test result type") state the equation(s) and/or computer software or other methods applied to calculate the value(s).
Indicate whether the study was conducted following Good Laboratory Practice or not. Select "yes (incl. certificate)" if a GLP certificate of a test facility is available. Select "yes" if a GLP compliance statement is available, but no information on a GLP certificate. You can give an explanation in the supplementary remarks field, e.g. for explaining why GLP was not complied with or for specifying which (national) GLP was followed.
Indicate if the test material used in the study is equivalent to the submission substance identity. If "yes" is selected, the corresponding identity is automatically entered in the subsequent block of fields "Test material identity".
If "no" is selected, identify the test material in the subsequent block of fields "Test material identity". In this case, also make sure that the information entered in field "Study result type" is consistent, i.e. "read-across from supporting substance (structural analogue or surrogate)".
NOTE: If a completed record is used for another submission, you may have to update both fields "Study result type" and "Test material equivalent to submission substance identity".
If the identity of the test material used for this study is not included in this block of fields automatically, indicate the identity for one or more appropriate identifiers, e.g. CAS number, CAS name, IUPAC name. Copy this block of fields as appropriate.
If another than the submission substance identity was selected erraneously, go back to field "Test material equivalent to submission substance identity" and select "yes". This will prompt automatic entry of the respective identifiers.
Table E.82. Field Descriptions
| Identifier | Select an appropriate identifier from drop-down list, e.g. "CAS number". Use "Other:" and specify, if identity according to a standard identifier is not known or if an additional chemical name or number is provided. |
| Identity | Select the corresponding substance identity from drop-down list or enter manually if the identity is not available from the list or if no list is provided for the type of identifier selected. |
