Hello everyone My name is João Pedro Garcês and I'm working with polychaetes. I'm also very interested in studies related with pollution of aquatic ecosystems. I'm doing a Post Graduation Master in Ecological Modelling, and one of the studies that I have to do is develop a model. With this goal, I would like to develop a bio-accumulation model for metals and organic compounds like PCB'S with polychaetes. For that I initiate a search but didn't have great success. I would appreciate any help you can give me in this matter Thank you in advance for your responses Best regards João Garcês <joaogarces at mail.telepac.pt> -- ANNELIDA LIST Discuss = <annelida at net.bio.net> = talk to all members Server = <biosci-server at net.bio.net> = un/subscribes Archives = http://www.bio.net/hypermail/annelida/ Resources = http://www.annelida.net/ --
