Description of key information
Additional information
Stability
According to REACH Regulation (EC) 1907/2006 information about the phototransformation in air, water and soil is not mandatory for a registration of a chemical at a tonnage band of 100 - 1000 tons/year. However, the phototransformation in air was predicted by Chemservice S.A. (2011) with the computer program AOPWIN v1.92, resulting in an atmospheric half-life of 2.5 days (~ 30 hours, based on 12 h daily sunlight). No hydrolysis study was performed since the test substance is not expected to undergo hydrolysis due to the lack of functional groups that hydrolyse under environmental conditions. Furthermore, following REACH Annex VIII (section 9.2.2.1), a hydrolysis test is not required since the substance was found to be readily biodegradable (Kuhlmann, 1990).
Biodegradation
An experiment to investigate the biodegradation potential was conducted according to OECD Guideline 301E (Kuhlmann, 1990). After 28 days incubation period, 86 % degradation occurred, but not fulfilling the 10 -day window criteria (only 2 % degradation after 14 days and 19 % removal after 19 days incubation period). Based on these results 1-(3-sulphonatopropyl)pyridinium is assessed as readily biodegradable.
Bioaccumulation
The aquatic Bioconcentration factor (BCF) was determined by the computer program BCFBAFWIN v3.00 (Chemservice S.A., 2011). The regression-based estimate results in a BCF of 3.16 L/kg wet-wt. Using the Arnot-Gobas method, the BCF results in a value of 0.90 L/kg wet-wt. The result indicates a negligible bioaccumulation potential. For a registration of a substance in a tonnage band of 100 – 1000 tons/year, the assessment of terrestrial bioaccumulation potential is nevertheless not mandatory according to REACH Regulation (EC) 1907/2006.
Transport and distribution
No experimental data are available for adsorption/desorption of the substance to soil, therefore, a scientifically accepted calculation method was used (Chemservice S.A., 2011). With aid of the computer program KOCWIN v2.00 the organic-normalized sorption coefficient for soil, which is designated as Koc, was estimated. Applying the MCI method a Koc value of 28.87 L/kg is estimated indicating a low adsorption potential. The traditional method gives a value of 4.12 L/kg. Due to improved correction factors, the MCI method gives more reliable results. It is noted that these results represent a best-fit to the majority of experimental values. However, the Koc of the substance may be influenced by the surrounding pH.
Henry´s law states that the solubility of a gas in a liquid solution at a constant temperature will be proportional to the partial pressure of the gas which is above the solution (Henry, W., 1803). This information is not mandatory for a registration according to REACH Regulation (EC) 1907/2006 in a tonnage band of 100 - 1000 tons/year. However, Henry´s Law Constant can be predicted by using HENRYWIN v3.20 (Chemservice S.A., 2011). A constant of 4.59 E-6 Pa*m³/mol (at 25°C) was estimated for the test substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
