Adsorption:

Key study: The soil adsorption coefficient (Koc) of Camphene is 1204 (log Koc= 3.081). Estimated by EPI Suite (EPA, US).

Henry's Law constant:

Key study: The estimated Henry's Law constant for Camphene is 0.161 atm.m3/mole at 25 ºC. Estimated by EPI Suite (EPA, US).

Distribution modelling:

Using the Fugacity_LEVEL3NT model of EPI Suite, EPA (US) v3.20, the following results were obtained:

Percent distribution in media:

Air: 2.79%; Water: 40.9%; Soil: 40.1%; Sediment: 16.1%

Persistence time: 190 h = 8 d.

Half-Lifes; Air: 4.74 h; Water: 900 h = 38 d; Soil: 1,800 h = 75 d; Sediment: 8100 h = 338 d Volatilization from Water, Half life from model river: 1.195 hours; from model Lake: 110.9 hours, 4.621 days.
