Two recent problems in oil pollution research. Internat. Council Expl . Sea, 

 Fish. Improvement Comm. , Copenhagen, 9 p. 



Mercenaria mercenaria collected from an area of chronic oil and organic 

 waste pollution and transferred to an unpolluted area showed the following 

 amounts of contamination: as collected 16.0 ug/kg benzo (a) pyrene content; 

 7 weeks after transfer to an unpolluted area 8.2 ug/kg; 16 weeks after 

 transfer 0.9 ug/kg, and >60 weeks after transfer 1.1 ug/kg. These results 

 show that BP is not retained indefinitely, but is either metabolized or lost 

 by solution in the water. Present results show that from the fisheries 

 point of view sinking is not an ideal way of dealing with floating oil.

The lutein content of corb shell, Corbioula japonioa, is 10 to 20 times more 

 than hard clam. - from authors' English summary - (Abstracter's note: The 

 text is in Japanese, and nowhere does the scientific name of the hard clam 

 appear. The reference may be to a Japanese species.) - J.L.M.

On the occurrence of Venus mercenaria (Linn.) in the estuary of the Dee. Proc. 

 Chester Soc. Nat. Sci. 3: 111-112. 



Heppell (1961) reported that Shrubsole found on the beach more than 100 single 

 or double valves of Venus mercenaria. The shells were so fresh that the 

 ligaments were perfect. It was estimated that they had not been dead more 

 than a week or so. This finding in 1882 confirmed survival of clams stored in 

 the area in 1879. From the size of some shells it was estimated that they 

 were only a few months old. However, Heppell cited a letter from Shrubsole to 

 Marrat (1883) which stated that the shells were 1 to 3 inches, and over. Thus, 

 they did not prove that successful spawning had occurred. Shrubsole described 

 the growing areas in the Mersey as sandbanks. - J.L.M.
