PNEC STP, data displayed in milligram per litre. When more than one result is available per endpoint the ‘worst case’ or most conservative of all the data values provided are displayed, applying a precautionary principal. Values are presented in (nano/ micro/milli)gram per litre and/or (nano/ micro/milli)molar per litre. Values are generally displayed in milligram per litre. There is no overall agreement among data submitters, but a minority indicate they consider this substance as Skin sensitising (16.67% of REACH registrations). Brief Profiles are updated regularly and new information is added when available. Displayed are the RANGES of min – max of the PRIORITISED value(s) within the five highest priority groupings of provided data. Data is generally displayed in milligrams per kilogram bodyweight per day. While the Agency tries to aggregate the information on chemicals in the best possible way, ECHA cannot check whether all the information provided by industry is free of errors. However, substance notifications in the Brief Profile are aggregated independently of the impurities and additives. Water solubility provides substance information on the substance’s solubility in water in grams per litre at a temperature measured in °C. Processable data for study results is prioritised by test species (see list below) and subsequently further prioritised by the dose descriptor. Phototransformation in soil provides substance information on the substance’s phototransformation in soil in seconds/minutes/hours/days/weeks/months/years. Data generally displayed in milligrams per kilogram bodyweight per day. Phototransformation in water provides information on the substance’s phototransformation in water in seconds/minutes/hours/days/weeks/months/years. This Brief Profile is covered by the ECHA Legal Disclaimer. The % is based on count of values provided. Looking up values in one table and outputting it into another using join/awk. If so, the data provided is not processed for the Brief Profile. 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. Notification – indicates that notified C&L’s have been submitted to ECHA for a substance. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Sed elementum odio augue, eget iaculis lorem faucibus vel. Data from all dossiers registered for the same substance is used in the summarisation and aggregation process, as it is presumed that all data submitted by the registrants is relevant for the substance being registered. Values are presented in (nano/ micro/milli)gram per litre and/or (nano/ micro/milli)molar per litre. Otherwise data is displayed as provided by the registrant(s). The ‘Regulatory context’ section provides an overview of the regulatory activities that are related to the substance. Why does potassium dichromate always reacts in an acidic medium? Pre-registration allows companies to continue manufacturing and importing their. If impurities and/or additives have been identified, an informative sentence is displayed below the graphic. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. For example CLH index numbers, CN numbers, deleted CAS numbers, etc. This section summarises the values related to toxicity to birds from all registered dossiers for the substance. Half-life in air provides substance information on the substance’s dissipation half-life in air in seconds/minutes/hours/days/weeks/months/years. COD provides substance information on the substance’s COD values displayed in O2 (milli)gram per gram test material. Flash point provides substance information on the substance’s flash point at a temperature measured in °C at a pressure measured in Pascal. This section summarises the values related to Henry’s law constant (H) from all registered dossiers for the substance. Other release to the environment of this substance is likely to occur from: indoor use as reactive substance. 5. If so, the pressure data provided is not processed for the Brief Profile. The CAS number is the substance numerical identifier assigned by the Chemical Abstract Service, a division of the American Chemical Society, to substances registered in the CAS registry database. Pre-registration – indicated if the substance is included in the list of pre-registered substances. Data is generally displayed in milligram per kilo bodyweight. Koc provides substance information on the substance’s Koc adsorption at a temperature measured in °C and a percentage of organic carbon. 1 000 g will be displayed as 1 kg. How can I make the seasons change faster in order to shorten the length of a calendar year on it? 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. H dimensionless volumetric basis provides substance information on the substance’s Henry’s Law Constant in dimensionless volumetric basis at a temperature measured in °C and a pressure measured in Pascal. Officially recognised in the EU as Respiratory sensitising ( Harmonised C&L). This section displays the values related to irritation and corrosion from all registered dossiers for the substance. Other relevant information includes the following: To see the full list of notified classifications and have more information on impurities and additives relevant to classification, you can consult the C&L Inventory. Bulk density provides substance information on the bulk density in (kilo)grams per (centi)metre (cm/m) at a temperature measured in °C. Translated names gives the names in different EU languages, where available to ECHA. rev 2020.11.24.38066, The best answers are voted up and rise to the top, Chemistry Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us, $$\ce{Cr2O7^2- + 14 H+ + 6e- <=> 2 Cr^3+ + 7 H2O} \qquad E^{\circ} = \pu{1.36 V}$$, $$\ce{Cr2O7^2- + 14 H+ + 6 MnO4^2- -> 2 Cr^3+ + 6 MnO4^- + 7 H2O} \qquad E^{\circ}_{\text{Rxn}} = \pu{0.802 V}$$, Potassium Manganate and Acidified Potassium Dichromate colour changes [closed], MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…, “Question closed” notifications experiment results and graduation, Difference in the functioning of alkaline and acidified KMnO4.
