Toxicity of three oils to bivalve gametes and larvae. Mar. Pollut. Bull. 

 6(8): 125-128. 



Water soluble extracts of three crude oils, Kuwait, Nigerian, and Prudhoe 

 Bay, were tested on sperm and eggs of Mulinia lateralis and Crassostrea 

 virgin-Lea. Fertilization was depressed and developmental abnormalities 

 sometimes appeared after exposure to these toxins. Spermatozoa, in partic- 

 ular, were very sensitive to water-soluble fractions of these oils. Nigerian 

 crude is particularly toxic. Mercenaria mercenaria was not mentioned.

The kidney of the quahog (Mercenaria mercenaria) as a pollution indicator. 

 In Animals as Monitors of Environmental Pollutants. National Academy of 

 Sciences, Washington, D.C.: 119-129. 



Kidneys of quahogs collected from 10 variously polluted areas in Rhode 

 Island were analyzed histochemically , chemically, and histopathologically 

 with methods involving light, electron microscopy, and atomic absorption. 

 - The quantity, size, and color of kidney concretions in quahogs (Mercenaria 

 mercenaria) from high-pollution areas were different from those collected 

 in areas of low pollution. Analysis of concretions showed a predominance 

 of heavy metals. Interelemental ratios of trace metals depended on various 

 colors of concretions. Metals determined were Mn, Ca, Zn, Cu, Pb, Cd, and 

 Fe . Elemental analysis of concretions and other histopathological features 

 of molluscan kidney may be a convenient method of tagging various heavy 

 metal pollutants in the water sediment environment to which the benthic 

 community is exposed. Quahogs collected at Sabin Point had many more kidney 

 concretions than those collected at Charlestown Pond. - J.L.M.

Digestive processes in subtital Mercenaria mercenaria (Linn.). Amer. Zool. 

 19(776): 1006 (abstract). 



Digestive gland tubules were classified into one of four categories, indica- 

 tive of the state of intracellular digestion. Digestive processes did not 

 correlate with solar day, tidal cycle, salinity, or bottom water temp fluc- 

 tuations. Patterns of secretion or dissolution of the crystalline style 

 were discerned from either style length measurements, dry weight data, or 

 histological study of the style sac epithelium. Peak numbers of adsorptive 

 phase digestive tubules were found 3 hrs after peak levels of particulate
