_________________
n-Heptane:
Toxicity:
LC50 Daphnia magna (Water flea) >10 mg/L/24 hr
LC50 Mysidopsis bahia (Opossum shrimp) 0.1 mg/L/96 hr
LC50 Carassius auratus (Goldfish) 4mg/L/24 hr
Persistance and Degradability: Expected to biodegrade in soil based on 100% degradation after 4 and 25 days in
screening tests using gasoline contaminated soil and activated sewage sludge inocula, respectively.
Bioaccumulative Potential: An estimated BCF of 2,000 suggests the potential for bioconcentration in aquatic
organisms is very high. If released into water, n-heptane is expected to adsorb to suspended solids and sediment
based upon the estimated Koc.
Mobility in Soil: Expected to have no mobility based upon an estimated Koc of 8,200.

Ethylbenzene:
Toxicity:
LC50 Lepomis macrochirus 32 mg/l/96 hr
LC50 Carassius auratus 94.44 mg/l/96 hr
LC50 Pimephales promelas (fathead minnow) 12.1 mg/l/96 hr
Persistance and Degradability: Volatilization from moist soil surfaces is expected to be an important fate process
based upon a Henry's Law constant of 7.88X10-3 atm-cu m/mole. Ethylbenzene may volatilize from dry soil
surfaces based upon its vapor pressure. Biodegradation in soil takes place via nitrate-reducing processes. If
released into water, ethylbenzene may adsorb to suspended solids and sediment in water based upon the estimated
Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's
Henry's Law constant.
Bioaccumulative Potential: Measured BCFs of 0.67 to 15 suggest the potential for bioconcentration in aquatic
organisms is low.
Mobility in Soil: Expected to have moderate mobility based upon an estimated Koc of 520.
