Ready biodegradation:

The biodegradation of N-(2-nitrophenyl)phosphoric triamide was investigated in a study according to EU Method C.4-B (Determination of the "Ready" Biodegradability - Modified OECD Screening Test). N-(2-nitrophenyl)phosphoric triamide was not readily biodegradable under the conditions of the test performed. No biodegradation was observed.

Aerobic soil degradation:

N-(2-nitrophenyl)phosphoricacid triamide was tested in aerobic soil on the basis of OECD/OCDE Guideline no.307 for the testing of chemicals, adopted April 24, 2002. The study was performed in the laboratory using analytical grade N-(2-nitrophenyl)phosphoricacid triamide (purity of 99 % minimum). The DT-50 values of N-(2-nitrophenyl)phosphoricacid triamide in the LUFA 2.1, LUFA 2.2 and LUFA 2.3 were 5.3, 3.9 and 8.6 days. The DT-90 values of N-(2-mtrophenyl)-phosphoricacid triamide in the LUFA 2.1, LUFA 2.2 and LUFA 2.3 were 17.7, 13.0 and 28.6 days.
