Description of key information
Summary table
| Key value | Comments |
Phototransformation in air | DT50 = 2.29 h | Calculation (AOPWIN v. 1.85) |
Hydrolysis | Hydrolytically stable | OECD TG 111, EPA 161-1 |
Phototransformation in water | DT50 = 60 – 64 days (summer sunlight latitudes of 30°N - 50°N), pH 7, 25°C DT50 = 82 - 84 days (summer sunlight latitudes of 30°N - 50°N), Quantum yield of 1.01 E-5 molecules degraded/photon
| EPA 161-2, draft OECD TG Phototransformation of Chemicals in Water- Direct and Indirect Photolysis, JMAFF-12 Nohsan No 8147
|
Phototransformation in soil | DT50 = 68 - 72 (pyrazole labelled ) or 65 – 68 (phenyl labelled) days of summer sunlight (latitudes of 30 - 50°N). | EPA 161-3, draft OECD TG Phototransformation of Chemicals on Soil Surfaces |
Biodegradation in water: screening tests | not readily biodegradable | EU Commission Directive 92/69 EEC, C.4-D and OECD TG 301 F |
Biodegradation in water and sediment: simulation tests | DT50 freshwater-sediment >> 1 year (n = 2); 20 ˚C | OECD TG 308, EPA 162 -3, EPA 162 -4 |
Biodegradation in soil | DT50 in soil aerobic condition = 227 days (geomean; n=12); 20 ˚C | OECD TG 307 and EPA 162 -1 |
Bioaccumulation: aquatic / sediment | BCFk (calculated)= 406 L/kg BCFk (After 5% lipid content normalization) = 360 L/kg, whole fish | OECD TG 305 and OPPTS 850.1730 |
Adsorption / desorption | Koc = 2485 mL/g (arithmetic mean; n = 9); 20 ˚C | OECD TG 106, EPA guideline 163.1 and Canada PMRA guideline T-1 -255 |
Henry’s law constant | 1.9E-04 Pa.m³/mol for syn-isomer; 3.7E-05 Pa.m³/mol for anti-isomer | Calculation |
Other distribution data: Column Leaching | 3 Brazilian soils, 200 mm rainfall, 48 hours: Radioactivity in leachates at or below LOQ (0.08% AR). In all soils, majority of radioactivity in 0 - 5 cm layer. In the lower layers, radioactivity < 0.5% AR for 2 soils. The third soil showed 1.4% AR in 5 -10 cm layer and < 0.5% AR for the remaining soil (> 10 cm). Only parent compound was found in soil extracts. The relative mobility factor for soil I, soil II and soil III were 0.12 (immobile), 0.24 (slightly mobile), and 0.09 (immobile), respectively. | OECD TG 312 |
Additional information
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.
