The Concentrations of C j,-C,,^ N -Paraffins and Di-Tri- Aromatic Hydrocarbons in 



the Test Oils and in Water-Soluble Fractions (WSFs) Prepared From Them. 



Hydrocarbon Concentrations in the Oils are Given as Percent (g/100 ml) 



and in the WSFs as Parts Per Billion (jig/L) in 20 %c Seawater.

the oysters were returned to oil-free sea water they released 90% of 

 the accumulated paraffins in 24 hours and naphthalenes in 28 days. 



Similar patterns of petroleum hydrocarbon accumulation and re- 

 lease were observed in several other species of invertebrates and fish. 

 Regardless of the animal or test oil utilized, the hydrocarbons accumu- 

 lated to the greatest degree and retained the longest were the naphtha- 

 lenes. The time required for complete depuration varied with the 

 species involved, the length of exposure and the concentration and 

 composition of the exposure mixture. In general shrimp and fish, when
