摘要：20 fouling organisms were observed on plastic litter dredged from the Elbe estuary during July 1990; 60% of the species were typical sessile hard bottom organisms. Most individuals found on this artificial hard bottom were barnacles (Balanus crenatus, Elminius modestus), the musselMytilus edulis and the polychaeteLanice conchilega. All individuals were juveniles which had settled only recently on the plastics. The earliest settlers were not much older than 4–8 weeks.
