Persistence and degradability

no data available

Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for 1H-1,2,4-triazole(SRC), using a log Kow of -0.58(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1H-1,2,4-triazole can be estimated to be 5(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1H-1,2,4-triazole is expected to have very high mobility in soil.

Other adverse effects
