Values are displayed in milligram per litre. How to sustain this sedentary hunter-gatherer society? Dynamic viscosity at 20°C provides substance information on the substance’s (dynamic) viscosity per millipascal second at a temperature of 20°C. Add details and clarify the problem by editing this post. This section summarises the values related to Henry’s law constant (H) from all registered dossiers for the substance. REACH registration dossiers notifications. For example, an update in a section of a dossier that is not displayed in the Brief Profile will not result in an update of the Brief Profile. Log Koc at 20°C provides substance information on the substance’s log Koc adsorption at a temperature 20 °C. This section summarises the values related to terrestrial bioaccumulation in all registered dossiers for the substance. Substances may have impurities and additives that lead to different classifications. Displayed are the RANGES of min – max of the PRIORITISED value(s) within the five highest priority groupings of provided data. Data is generally standardised and displayed in in milligram per kilo of food. Vapour pressure provides substance information on the vapour pressure in Pa at a temperature measured in °C. For sections such as substance use, chemical properties and the classification and labelling of substances, the quantity and quality of the information is the responsibility of manufacturers and importers. Bioaccumulation factor (terrestrial species) provides substance information on the substance’s terrestrial bioaccumulative properties not taking account the dimensions. This substance is used in the following areas: scientific research and development. For substance’s physical state at 20°C and 1 013 hPa, registrants can classify their substance as: For substance’s form, registrants can classify their substance as: For substance’s odour, registrants can classify their substance as: For substance’s type, registrants can classify their substance as: Summary data is collected from the endpoint summary(ies) provided by registrants of REACH dossiers. Data is generally displayed in milligrams per kilogram in the case of soil (dry/wet weight) or gram per hectare. 5. Short-term EC50 or LC50 for mammals provides substance information on the substance’s effect concentration or lethal concentration (short term) for 50% of mammals in the test, generally displayed in milligram per kilo food. This section provides physicochemical information compiled from all automatically processable data from REACH registration dossiers that is available to ECHA at the time of generation. It may, for example, originate from the starting materials or be the result of secondary or incomplete reactions during the production process. This section provides an overview of the type of study records behind the presented results and – if applicable - data waving justifications. This section summarises the values related to phototransformation in air from all registered dossiers for the substance. What is the charge of potassium dichromate? Data is generally displayed in milligram per litre air. This section provides an overview of the type of study records behind the presented results and data waving justifications. Processable data is prioritised by the toxicity descriptor type (see list below) and subsequently further prioritised by duration (in hours, longer prioritised over shorter). I would be obliged if somebody could explain the colour changes for the reduction of potassium manganate and acidified potassium dichromate. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. This section summarises the values related to aquatic/sediment bioaccumulation in all registered dossiers for the substance. Thirdly the display of data is prioritised by units. Trade names gives all public trade names submitted to ECHA in REACH registrations. Classifications under REACH have to be supported by data (support studies). More detailed information is available in the dossiers. Information in the ‘Scientific properties’ section is structured by substance properties, further broken down into endpoints. The IUPAC nomenclature is a systematic way of naming chemical substances, both organic and inorganic. This section provides an overview of the type of study records behind the presented results and – if applicable - data waving justifications. Other identifiers gives any other non-name identifiers available for ths substance. Do other planets and moons share Earth’s mineral diversity? Short-term EC50 or LC50 for birds provides substance information on the substance’s effect concentration or lethal concentration (short term) for 50% of birds in the test, generally displayed in milligram per kilo food. An IUPAC name is based on the international standard chemical nomenclature set by the International Union of Pure and Applied Chemistry (IUPAC). If more than one type of substance is registered, both types will be displayed. If more than one picklist value is available per endpoint, results are displayed as concatenated distinct values, ordered by most to least commonly provided, with the % of provided values appended. If so, the data provided is not processed for the Brief Profile. Displayed is the most conservative of the prioritised value(s). Use of the information without obtaining the permission from the owner(s) of the respective information might violate the rights of the owner. Note: If the measurement condition (percentage of organic carbon) is not provided by the registrant for adsorption coefficient Kd, the data provided is not processed for the Brief Profile. Potassium dichromate(VI) Other . test not applicable because organic peroxide. In IUPAC nomenclature, prefixes, suffixes and infixes are used to describe the type and position of functional groups in the substance. Short–term toxicity to aquatic invertebrates, Long–term toxicity to aquatic invertebrates, Toxicity to aquatic algae and cyanobacteria, Toxicity to aquatic plants other than algae, Endocrine disruptor testing in aquatic vertebrates - in vivo, Toxicity to terrestrial macroorganisms except arthropods. Within the context of REACH, impurities are unintended constituents present in a substance as manufactured. This section summarises the vapour pressure values from all registered dossiers for the substance. The goal of CLP is to make sure that hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through a system of classifying and labelling of chemicals. The aim is to display the lowest values reported as causing the most adverse effects, and hence the broadest possible safety margins for the substance.
