marine biomonitors?

	I am preparing a proposal for using the mussel (Mytilus edulis) 
as a biomonitor in estuarian waters. Many areas in Eastern N. America 
culture this species in estuaries, so the organism is built-in. I did a 
tox. study on oil effects on seabirds using assay of elevated MFO enzymes 
in their livers as indicator. My idea is to plate these enzymes (if they 
exist in the mussel) along with the bacterial mutants used in the Ames 
Salmonella Mutagenicity Test, using the number of revertant colonies as a 
background, then use these plates to test the relative toxicity of 
sediments and concentrated water samples in coastal and benthic areas. I 
hope to apply this as useful monitor data to determine toxicity of 
sediment runoff from agricultural coastal land, as well as impact of 
offshore construction, drilling, etc.

	Anyone with experience in any aspect of this, please contact me 
directly or through this group.  

	As well, I would like to correspond with anyone knowledgeable in 
the topic of benthic sedimentation and possible toxic effects on 
organisms such as flounder, crab, scallop, or lobster. I am especially 
interested in the effects of marine or benthic toxins on chitin 
production in marine invertibrates and plankton. I know that certain 
pesticides inhibit chitin production. Thanks in advance for your interest.
