Substances potentially subject to further regulatory management. On the other hand, an increased of mortality after 28 days was observed (37.5% and 85.0% at the concentrations of 606 and 1000 mg test item/kg soil (dw) equiv. This substance is used in the following areas: agriculture, forestry and fishing. The amount of N has to be adapted to the requirement of the crop. Table 2: Number of dead earthworms after 28 days (n = 80 for control; n = 40 for concentrations). Please contact the manufacturer to enquire about the appropriate settings on the fertilizer spreader. [5] Fritz Rothe, a colleague of Frank and Caro, succeeded in 1898 in overcoming problems with the use of calcium carbide and clarified that at around 1,100 °C not calcium cyanide but calcium cyanamide is formed in the reaction. The per substance REACH registration status will be made available as soon as possible thereafter. It crystallizes in hexagonal crystal system with space group R3m and lattice constants a = 3.67 Å, c = 14.85 Å.[11][12]. This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. While the harmonized list covers many hazardous substances, other ones not listed may also meet the classification criteria in accordance with the CLP. Premium Membership is now 50% off! Acute toxicity of PERLKA to earthworms, Eisenia foetida Michaelsen, was determined in a 14-day soil exposure laboratory study conducted similar to OECD Guideline 207. Calcium cyanamide is also used as a wire-fed alloy in steelmaking, in order to introduce nitrogen into the steel. It is a fertilizer used in conventional agriculture with a high content of nitrogen , with gradual release. Table 1: Effects on Mortality (28d), Biomass (28d) and Reproduction (56d) of Eisenia fetida. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. The examples provided are generic examples and may not apply to the specific substance you are viewing. Mortality results and sublethal effects were not reported for each concentration. Reproduction (given as mean number of juveniles ± standard deviation and as % of the control) in the treated test vessels. 0000007844 00000 n When information is available in all sources, the first two are displayed as a priority. The sample tested contains 40-45 % calcium cyanamide. 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, C&L Inventory, Pre-Registration process, CAD - Chemical Agents Directive, Art.

It applies the European Agreements on the international transport of dangerous goods by road (ADR) and inland waterways (ADN), and the Regulations concerning the international carriage of dangerous goods by rail (RID). This substance is used in the following products: fertilisers. It was first synthesized in 1898 by Adolph Frank and Nikodem Caro (Frank-Caro process). 0000002549 00000 n For more precise details please refer to the recommendations for use with particular crops. The calcium cyanamide is found in granules or in powder form and is used only as a background fertilizer, so during the preparation of the soil . to 976.3 mg and 1611 mg Calcium Cyanamide, respectively). On the other hand, an increased of mortality after 28 days was observed (37.5% and 85.0% at the concentrations of 606 and 1000 mg test item/kg soil (dw) equiv. This information is supplemented by acute toxicity studies: Acute toxicity of calcium cyanamide to earthworms, Eisenia foetida and Lumbricus terrestris, was determined in a 14-day soil exposure laboratory study conducted similar to OECD Guideline 207 (Heimbach, 1984). Worms were assessed for mortality and sublethal effects after 7 and 14 days of exposure and earthworm body weights were assessed at day 0 and day 14. The NOECof 533 mg/kg soil dw obtained for the test material was re-calculated to 100 % calcium cyanamide. Release to the environment of this substance can occur from industrial use: as an intermediate step in further manufacturing of another substance (use of intermediates) and as processing aid. When the plants are stressed (drought, heat, frost, etc.) The precautionary measures and guidance on safe use are as submitted to ECHA by registrants under the REACH Regulation. Scheffczyk (2016) conducted a second study according to OECD guideline 222 (Earthworm Reproduction Test (Eisenia fetida/ Eisenia andrei)) with a 50% aqueous solution of cyanamide. 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Inland Transport of Dangerous Goods Directive, Annex III - ADN, Inland Transport of Dangerous Goods Directive, Annex I - ADR, Inland Transport of Dangerous Goods Directive, Annex II - RID, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, La communication au sein de la chaîne d’approvisionnement, Liste de substances candidates dans des articles, Publication des informations contenues dans les dossiers, Statistiques relatives aux enregistrements, Identification des substances extrêmement préoccupantes, Recommandation d’inclusion dans la liste d’autorisations, Activités de l’ECHA en matière de restrictions, Élaboration d’une proposition de restriction, Informations sur les substances faisant l’objet d’une restriction, Introduction à la législation de l’UE sur les produits chimiques, Substitution par des produits chimiques plus sûrs, Classification des substances et des mélanges, Classification et étiquetage harmonisés (CLH), Nom chimique de remplacement dans des mélanges.

Substances intended to be restricted and entered in Annex XVII to REACH. The purpose of this study was to determine a NOEC/LOEC and if possible, an EC10, EC20 and EC50 value for reproduction (56 days after application) and a NOEC/LOEC value for mortality and the biomass development (28 days after application) of the earthworm Eisenia fetida (Lumbricidae) using a standard LUFA 2.2 soil. No significant sublethal behavioural effects were observed up to a rate of 500 mg SKW Cyanamid L500 + AHL/kg dry soil weight. to 976.3 mg and 1611 mg Calcium Cyanamide, respectively). However, such a bounded NOEC value is currently not available and could only be determined by repeat testing. This directive requires employers to ensure proper signage is posted in areas where hazards cannot be avoided or reduced. 0000002578 00000 n Three replicates of 6 or 10 clitellated adult earthworms were each exposed to doses in a geometric series, in order to determine a LC50 value. The LC50 of PERLKA was determined to be 261.4 mg product/kg dry soil, with a confidence interval of 251.3 to 272.0 mg product/kg dry soil, and a slope of 95%. This section provides links to the list of precautions (precautionary statements) and to the guidance on safe use, if they have been provided in REACH registration dossiers. L’ECHA organise des consultations afin de recevoir un retour d’information de la part de toutes les parties intéressées et de rassembler l’éventail le plus large possible d’informations scientifiques pour les processus réglementaires.
