Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Description of key information


The calculated logKoc value of 2.49 (Bayer Industry Service, 2006, QSAR with limited documentation) as well as the findings by Haas and Loew, 1986 point at a slight adsorption potential of 3-nitrotoluene (cited in the BUA report: indications for a high degree of adsorption and/or elimination of nitrotoluenes as they pass horizontally through the soil. The elimination may result from the degradation of the nitrotoluenes, e.g. by soil organisms and/or from the volatility of the mononitrotoluenes).


Henry's Law constant

Several experimentally determined measured values were reported: 0.94 Pa*m3/mol at 25 °C (Altschuh, 1999) and 14 M atm-1 at 25 °C (reported by Deno and Berkheimer (1960) and cited in Betterton, 1992). The Henry's law constant's value was calculated with the software EPI Suite (HENRYWIN v. 3.10). The QSAR calculation resulted in the following value (bond method): 2.38 Pa*m³/mol at 25°C (QSAR calculation, Bayer Industry Services, 2006).


Distribution modelling

Based on the model calculations (Mackay level I, v.2.11, Bayer Industry Services, 2006), the target compartment for the environmental distribution of 3-nitrotoluene is air (75%).
Water: 24%
Soil: 0.5%
Sediment: 0.5%
Susp. Sediment:<0.01 %
Biota (fish): <0.01 %
Aerosol: <0.01 %
