If such measurements are variable in time, the time dependency must be determined by calculation or measurement. EC10 / LC10 or NOEC for freshwater plants provides substance information on the substance’s effect concentration/lethal concentration for 10% of the tested freshwater plants or the no observed effect concentration for freshwater plants. Non-standard AR coatings are used when coating LiF material. With this transition, an amount of light is emitted that is proportional to the amount of radiation dose. Melting/freezing point at 101 325 Pa provides information on the substance melting/freezing point in °C at a pressure of 101 325 Pa. Radiation interacts with the atoms in the film to expose the film. This substance is used in the following products: welding & soldering products, metals, adsorbents, metal surface treatment products and heat transfer fluids. Substance evaluation – indicated if the substance is or was included in the Community rolling action plan (CoRAP). 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. Results without measurement conditions (pressure) are not processed for the Brief Profile. 6-30A). The Candidate List includes substances that are subject to additional protocols and reporting obligations and which may eventually be included in the Authorisation list, further limiting their use. It does not represent a new labelling, classification or hazard statement. PNEC STP, data displayed in milligram per litre. Please be aware there may be intermittent unavailability while work in ongoing. Data is generally displayed in milligram per kilo bodyweight. BOD5*100/ThOD provides substance information on the substance’s BOD5*100/ThOD values displayed in O2 (milli)gram per gram test material. The % is based on count of values provided. Data is generally displayed in milligrams per kilogram in the case of soil (dry/wet weight), or gram per hectare. Registrants can choose from the following picklist endpoint conclusions/effect levels: Eye irritation provides substance information on the substance’s irritation effect on the eye. If the substance is classified under more than one CLH entry (e.g. Lithium has two stable isotopes, lithium-6 (7.4 %) and lithium-7 (92.6 %). Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. Registrant can provide information on eye exposure as mentioned above for ‘Data for workers – eye exposure.’. Note: Registrants can also select ‘BMD’, ‘BMC’, ‘dose level’ and ‘conc. More info. Note: Registrants can also select ‘other’ as the type of Henry’s law constant. Bioaccumulation Factor (terrestrial species) L/kg ww provides substance information on the substance’s terrestrial bioaccumulative properties measured in litre per kilogram (wet weight). Within each of these categories, data is prioritised further by duration (in hours), with longer prioritised over shorter. Candidate List – indicates if the substance is included in the candidate list of substances of very high concern (SVHCs). For the crystallographic analysis of lithium fluoride we used the Nickel filter to have monochromatic emission in … This substance is used in the following areas: building & construction work. cutlery, pots, toys, jewellery) and metal used for furniture & furnishings (e.g. Do you have a question you'd like to ask regarding this article? Additionally, the wide difference between apparent deficient intakes (based on rat experiments) and typical daily intakes inhibits the suggestion that lithium could be of practical nutritional importance. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): Welcome to the ECHA website. For example, substance impurities can constitute a valid reason for a different classification of the substance. It may, for example, originate from the starting materials or be the result of secondary or incomplete reactions during the production process. Data is generally displayed in milligrams per kilogram in the case of soil (dry/wet weight), or gram per hectare. REACH regulation aims to improve the protection of human health and the environment from the risks that can be posed by chemicals. They are worn on the outer clothing and are used to measure gamma, x-ray, and high-energy beta radiation. If additional information derived from classification and labelling (C&L) notifications to ECHA under the CLP Regulation exists, this will be displayed below the information derived from harmonised classification and labelling and REACH registrations. Henry’s Law Constant provides substance information on the substance’s Henry’s Law Constant measured in in Pa.m3.mol-1 at a temperature measured in °C. Note: Registrants can also select ‘other’ as the test species. Substances which have been registered and can be placed on the EEA market by those companies with a valid registration. These fibers yielded a pattern of 26 smeared diffraction spots that were symmetrically positioned in groups of four around two mirrors planes.54 Similar albeit less clear, patterns of X-ray diffraction in cellulose were also produced in the same year by Scherrer. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. The NaI crystal is coupled to a photomultiplier tube that amplifies the detection signal coming from the crystal (Fig. COD provides substance information on the substance’s COD values displayed in O2 (milli)gram per gram test material. the electronic edition of the Official Journal of the European Union. Processable data is prioritised by the toxicity descriptor type (see list below) and subsequently further prioritised by duration (longer prioritised over shorter). Registrants can report substance information on viscosity as: Static viscosity at 20°C provides substance information on the substance’s (static) viscosity per square millimetre per second at a temperature of 20°C. It is possible that the harmonisation is introduced through an amendment to the CLP Regulation. As the charge is lost, the fiber moves to some new position on the scale that indicates the amount of radiation exposure.
