- Conclusions:
- EPI Suite has estimated Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate), is expected to be found predominantly in soil and it’s persistence estimate is based on its transformation in this medium. Its half-life in soil is estimated to be 120 days (2880 hrs).
Therefore, Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate), is estimated to be persistent in the soil. environment. - Executive summary:
EPI Suite has estimated Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate), is expected to be found predominantly in soil and it’s persistence estimate is based on its transformation in this medium. Its half-life in soil is estimated to be 120 days (2880 hrs).
Therefore, Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate), is estimated to be persistent in the soil environment.
