There are four methods to aggregate and summarise data, depending on the available data and endpoint. Data from all dossiers registered and the Classifications and Labelling Inventory (C&L) for the same substance are used to generate the Brief Profile. Hung., 51(4), 1967, 359-369. umn class: Semi-standard non-polar; Column length: 1 m; Column type: Packed; Start T: 100 C; CAS no: 10026047; Active phase: Apiezon L; Carrier gas: Ar; Data type: Kovats RI; Authors: Kreshkov, A.P. This section summarises the density values from all registered dossiers for the substance. Note: Results without a concentration value are not processed for the Brief Profile. S is the number of shared electrons. Values are generally displayed in milligram per litre. Log Koc provides substance information on the substance’s Koc adsorption at a temperature measured in °C and a percentage of organic carbon. When submitted by the lead of a joint submission, the classifications may also reveal agreement between companies. Regulatory process names gives the names under which the substance appears in ECHA's regulatory processes and lists. Khim., 27, 1972, 816-821. umn class: Standard non-polar; Column length: 2 m; Column type: Packed; Start T: 40 C; CAS no: 10026047; Active phase: SE-30; Carrier gas: N2; Substrate: Chromosorb W; Data type: Kovats RI; Authors: Garzo, G.; Fekete, J.; Blazso, M., Determination of the gas chromatographic retention indices of various organometallic compounds, Acta Chim. Thirdly the display of data is prioritised by units. Values are generally displayed in milligram per litre. No or insufficient data available at present, Hazard related to composition of atmosphere identified, No potential to cause toxic effects if accumulated (in higher organisms) via the food chain, bw/day (mg/kg bw/day; mg/kg bw/day; mg/kg bw/day), DMEL (Derived Minimum Effect Level) - not included for short–term effects, Insufficient data available (further information necessary), Hazard unknown (no further information necessary), Hazard unknown but no further hazard information necessary as no exposure expected, ‘No DNEL required: short term exposure controlled by conditions for long-term’ is added, Hamster (combine hamster, Armenian; hamster, Chinese and hamster, Syrian), No adverse effect observed (not irritating), Adverse effect observed (irreversible damage), mg/kg bw/day (nominal/actual dose received), See ‘Study results oral: Prioritization by test species’, mg/L air (combining mg/L air, mg/L air (nominal), mg/L air (analytical), mg/m³ air, mg/m³ air (nominal), mg/m³ air (analytical)), ppm (combine ppm, ppm (nominal), ppm (analytical), mg/kg bw/day (actual dose received), mg/kg bw/day (combining mg/kg bw/day (nominal), mg/kg bw/day (actual dose received) and mg/kg bw/day), mg/cm² per day (combining mg/cm² per day, mg/cm² per day (nominal), mg/cm² per day (analytical)), No study available / no study available (further information necessary). Molecular structure . This section summarises the values related to toxicity to mammals (other above-ground organisms) from all registered dossiers for the substance. Siridion(R) STC . Registrants can register their substance’s oxidising properties as: Note: Registrants can also select ‘other’ as the oxidising value for their substance. EC10 / LC10 or NOEC for freshwater invertebrates provides substance information on the substance’s effect concentration/lethal concentration for 10% of the tested freshwater invertebrates or the no observed effect concentration for freshwater invertebrates. For general information about any of the different regulations which currently fall under ECHA’s mandate please see the links below. Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)The REACH Regulation (1907/2006) entered into force on 1 June 2007. Surface tension provides substance information on the surface tension in (milli)Newton per metre in a concentration in (milli)gram per metre and at a temperature measured in °C. This section summarises the values related to biodegradation in soil from all registered dossiers for the substance. Bioaccumulation Factor (aquatic species) L/kg ww provides substance information on the substance’s bioaccumulative properties for aquatic species measured in litre per kilogram  (wet weight). This section provides toxicological information compiled from all automatically processable data from REACH registration dossiers that is available to ECHA at the time of generation. Authorisation list (Annex XIV) – indicates if the substance is included in the Authorisation List. Degradation rate constant (Ozone) provides substance information on the substance’s degradation rate constant with Ozone as a reaction type in cm3molecule-1s-1, cm3molecule-1d-1, m3molecule-1s-1 or m3molecule-1d-1. EC/LC50 for freshwater plants provides substance information on the substance’s effect concentration or lethal concentration for 50% of the freshwater plants in the test, generally displayed in milligram per litre. This section summarises the flammability values from all registered dossiers for the substance. Cl, group 7 or 17 has 7. Biocidal product authorisation – indicates if authorised biocidal products exist which use this substance as an active ingredient. LC50 for marine water algae provides substance information on the substance’s lethal concentration for 50% of the marine water algae in the test, generally displayed in milligram per litre.
