Abstract | Short necked clams (Venerupis Amygdala japonica) were maintained in a controlled laboratry environment in sea water containing suspension of crude oil and then transferred to clean sea water. Transfering and disappearance of n-paraffins in the soft body of short necked clams were examined by gaschromatography. n-Hexane solution after clean up treatment was treated by distribution method with n-hexane and acetonitrile and were separated n-paraffins and aromatic hydrocarbons. Short necked clams were reared in oil disperser or supplement with C(20), C(22), C(24) of n-paraffins and n-paraffins in soft body of short necked clams were analyzed by gaschromatography. The following reasults were obtained. 1) C(13)-C(2O) of n-paraffins in crude oil were transfered in the soft body of short necked clams. The concentration of n-paraffins increasd with rearing time in crude oil suspension and decreased with crean sea water. The rate of disappearance of C(10)-C(15) in n-paraffin were decreased faster than C(16)-C(20) of n-paraffins. 2) Short necked clams were reared in the crude oil suspension (1,000 ppm) for 3 days. n-Hexane solution after clean up was treated by distribution method. n-Paraffins remains in n-hexane and di-, tri-cyclic aromatic hydrocarbons transfered from n-hexane solution to acetonitrile solution. 3) Short necked clams were reared in oil disperser solution (100 ppm). Gaschromatograms of soft body of short necked clams showed the presence of C(12)-C(16) of n-paraffins. Short necked clams were reared in oil diperser solution supplemented with C(20), C(22), C(24) of n-paraffins. Gaschromatograrm of soft body of short necked clams showed the presence of C(20), C(22), C(24) of n-paraffins except C(12)-C(16) of n-paraffins of oil disperser.
