According to a Mackay Level I model calculation the main target compartment for 1,2,3,4-tetrahydronaphthalene will be the atmosphere (94.6 %) followed by the hydrosphere (2.7 %), sediment and soil (1.3 % each). The experimental Henry’s Law constant of 138 Pa m3/mol at 20 °C indicates high volatility of 1,2,3,4-tetrahydronaphthalene from surface waters. With an experimental Koc of 501 l/kg, the sorption potential of 1,2,3,4-tetrahydronaphthalene to soil or sediment organic matter is expected to be moderate (Blume scale).
