Metallföroreningar i Landskrona - miljöövervakning med blåmussla
(2014) MVEK02 20141Studies in Environmental Science
- Abstract
- Environmental monitoring using bioindicators is a valuable tool in quantifying and assessing metal pollution in the aquatic environment. In this study, I have analyzed monitoring data on metals in blue mussels (Mytilus Edulis) from the Öresund in Landskrona, Sweden. Comparisons with previous monitoring studies from the area show elevated concentrations of several metals, including copper (Cu), lead (Pb) and zinc (Zn), suggesting a local source of pollution in Landskrona. Deviations from guideline values calculated by the swedish EPA, representing baseline values, are shown to be Large or Very Large for copper, lead, nickel (Ni) and tin (Sn). In addition, lead and cadmium (Cd) concentrations in mussels exceed limit values for foodstuff... (More)
- Environmental monitoring using bioindicators is a valuable tool in quantifying and assessing metal pollution in the aquatic environment.

Deviations from guideline values calculated by the swedish EPA, representing baseline values, are shown to be Large or Very Large for copper, lead, nickel (Ni) and tin (Sn). In addition, lead and cadmium (Cd) concentrations in mussels exceed limit values for foodstuff determined by the European Commission, rendering the mussels unsuitable for human consumption.
Multivariate principal component analysis (PCA) of the data show covariance between copper, lead, zinc and tin, suggesting a common source of pollution. GIS-analysis of the data show that the highest concentrations of copper, lead, zinc and tin are found in the area of Varvsudden, an industrial area with several metal industries, a large shipyard and a marina for recreational boating. Combined, these analyses suggest multiple pollution sources including industrial effluents and anti-fouling paint.
With the approach used in this study, continued environmental monitoring expanded with the quantification of abiotic factors can give more detailed insight on the metal pollution sources, providing a solid knowledge base for remediation and prevention of future pollution. (Less)
