Persistence and Degradability:
Hydro sulfurized Kerosene: 58.6 % in 28 days
Petroleum distillates hydro desulfurized light catalytic cracked: 66.8 % in 28 days
Hydro treated middle distillates: 60 % in 28 days
Petroleum distillates, hydro desulfurized middle: 60 % in 28 days
Petroleum distillates light hydrocracked: 60 % in 28 days
Naphthalene: Reached 2% of its theoretical BOD in 4 weeks
Methylcyclopentadienyl manganese tricarbonyl:
Less than 25% degradation occurred within 14 days.
Xylene: Readily biodegradable
Toluene: Readily biodegradable
Ethylbenzene: After a period of inocula adaptation, ethylbenzene is biodegraded fairly rapidly by
sewage or activated sludge inoculua.
Cumene: Not readily biodegradable
Benzene: Benzene present at 100 mg/L, reached 40% of its theoretical BOD in 2 weeks
using an activated sludge Inoculum.
Bio accumulative Potential:
Naphthalene: BCF 23 to 146, these BCF values suggest the potential for bio concentration in
aquatic organisms is low to high.
Xylene: BCF of 6 – 23.4
Toluene: BCF 90
Ethylbenzene: BCF 15
Cumene: Not likely to bio accumulate in aquatic organisms
Benzene: The potential for bio-concentration in aquatic organisms is low.
Mobility in Soil:
Naphthalene: Is expected to have moderate to low mobility in soil.
Xylene: Low mobility in soil.
Cumene: Low mobility in soil.
Benzene: Expected to have high mobility in soil.
