Hi Matthew,

Over the more than 20 years that I have been pawing through mesopsammic
meiofauna it is my subjective assessment that at least some Saccocirrus
are very tolerant of environments highly enriched in organics (some might
say polluted), but I don't know if any of the places I have worked would
have had heavy metal pollution. I haven't noticed any obvious differences
among specimens of different neighboring sites. You might want to contact
Eric McEvoy <e.g.mcevoy at livjm.ac.uk> at Liverpool John Moores University
about testing for metals in the specimens. He has been looking at heavy
metal accumulation in nemerteans. 

Cheers, --Jon
