The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

1,2,4 triazole is not readily biodegradable and is expected to be stable in water according to the results of the hydrolysis study (half-life > 30 days).

Nevertheless, results of simulation of degradation in soil (Tarara, 2004) indicated that 1,2,4 -triazole is degraded under the investigated conditions in northern and southern Europe. Half-life were determined between 6.8 to 28.1d.

1,2,4 triazole has a low octanol/water partition coefficient (Log Kow <1) and is very soluble in water. Based on these physico-chemical properties, triazole when released in the environment is expected to mainly partition in water phase. This is also supported by its Koc of 202 indicating that the substance is mobile in soil. In addition, it is not expected to bioaccumulate in organism tissues.
