Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

The present study was planned to assess the validity of Enteromorpha intestinalis for an active biomonitoring of heavy metals in the Weser estuary. Exposure of cultured algae (active biomonitoring) was carried out in 1987 and 1988, simultaneously Enteromorpha spp. was collected from the banks (passive monitoring) in the estuary. Cd, Pb, Ni, Zn and Cu contents of exposed algae were higher than the metal content of collected algae. Metal contents of both collected and field algae varied significantly over space and time. Bioconcentration factors and results of linear regression analysis indicate, that the bioavailability of Cu and Ni varies with regard to the sampling location but cannot be calculated from heavy metal concentration in the water. Due to the different metal and species specific bioavailability, we want to stress the need to monitor contamination of organisms directly. An active biomonitoring using E. intestinalis will establish a rationale to compare contamination of different estuaries.
