Effects of oil on marine organisms: a critical assessment of published data. 

 Water Research 8: 819-827. 



Oil has been reported as lethal to Mereenaria mereenaria. This should not be 

 taken to imply that extensive, valid data have been reported, but only that 

 some data may exist. Toxicity to bivalves generally is at the level of about 

 5 to 50 ppm of soluble aromatic fractions. Effects of several specific spills 

 on marine organisms generally are discussed. Significant levels of un- 

 certainty exist in all aspects of oil spill effects, but it is useful to 

 classify effects as lethal, sublethal, coating, habitat alteration, and 

 incorporation. Larval stages are more sensitive than adults. Additional 

 toxicity data, and more experimental and field studies of oil degradation 

 processes and ecological interactions are needed. Continuous discharges of 

 low concentrations of hydrocarbons should be regulated according to soluble 

 aromatic content, not total hydrocarbons. - J.L.M.

Note on a further local attempt to naturalize the American clam (Venus 

 mereenaria) . Proc. Lit. Phil. Soc . Liverpool 38: xc. 



According to Heppell (1961) Moore received a barrel of live hard clams from 

 New York. They were planted in several areas in the Humber estuary and the 

 River Dee and elsewhere. No evidence of survival was found later, but the 

 clams apparently were in good condition, for a few held in the Liverpool 

 Museum were alive at least 16 months later. - J.L.M.

Note on the possible naturalization of the American clam Venus mereenaria 

 on the coasts of Lancashire and Cheshire. 1st Rept. on fauna of Liverpool 

 Bay (Appendix to Proc. Lit. Phil. Soc. Liverpool 40): 368-370. 



According to Heppell (1961) an attempt was made by Moore in 1869 to 

 naturalize the hard clam. The only result was the rumored finding later 

 of a doubtful valve. - J.L.M.

Dopaminergic neurons: Activation of tyrosine hydroxylase by a calcium 

 chelator. Molec. Pharmacol. 12(1): 41-48. 



Addition of the calcium-chelating agent ethylene glycol bis ( B-aminoethyl 

 ether) -N,N ' -tetraacetic acid (EGTA) to a high-speed supernatant preparation 

 from rat striatum produced a dramatic increase in activity of tyrosine 

 hydroxylase assayed in presence of subsaturating concentrations of tyrosine 

 and reduced pterin cof actor. This activation appeared to be mediated by 

 changes in kinetic properties of tyrosine hydroxylase. This and other 

 kinetic alterations could be reversed by adding calcium to the assay medium, 

 but magnesium, even in high concentrations, was ineffective. Similar acti- 

 vation was observed with tyrosine hydroxylase isolated from the dopamine- 

 rich pedal ganglion of Mereenaria mereenaria. - J.L.M.
