I am not sure did my message pass earlier, we had problems with news. If did, sorry for nuisance. Does anybody know anything about ecotoxicological bioindicators in running water. My problem deals with a papermill putting its waste waters to a small river in Finland. I am also interested in experimenting in natural conditons. All references and contact addresses are welcome.
