Water -The atmospheric oxidation half life of methyl 5-nitrohydrogen.isophthalate was estimated using the level III multimedia model. The half life of methyl 5-nitrohydrogen.isophthalate in water is found to be 15 days therebu indicating that the substance is non persistent in the aquatic medium. The percentage of methyl 5-nitrohydrogen.isophthalate in the water medium was found to be only 29.6%.

Soil - The atmospheric oxidation half life of methyl 5-nitrohydrogen.isophthalate was estimated using the level III multimedia model. The overall persistence for methyl 5-nitrohydrogen.isophthalate is 30 days using the default emission scenarios of the level III multimedia model.

methyl 5-nitrohydrogen.isophthalate is expected to be found predominantly in soil and its persistence estimate is based upon its transformation in soil. Its half life in soil is 30 days which does not exceed the EPA criteria and thus it can be concluded that

methyl 5-nitrohydrogen.isophthalate is not very persistent in soil.

Since methyl 5-nitrohydrogen.isophthalate was found to be biodegradable in water and sediment as well as in soil (though the time taken for complete biodegradation is more), a study of its hydrolysis is not very crucial. Under the environmental conditions, hydrolysis is unlikely to make a significant contribution to the dissipation of methyl 5-nitrohydrogen.isophthalate compared to the rate of its removal by biodegradation.
