Effects of heavy elements (Pb, Cu, Zn) on algal food uptake by Elphidium excavatum (Foraminifera).

ABSTRACT: Foraminifera are unicellular organisms and play a pivotal role in the marine material cycles. Past observations have shown that the species Elphidium excavatum is the most common foraminifera in the Baltic Sea. Feeding experiments showed that the food uptake and thus the turnover of organic matter are influenced by changes of physical parameters (e.g., temperature, salinity). Since many areas of the Baltic Sea are strongly affected by anthropogenic activity and are strongly contaminated by heavy elements from shipping in the past, this study examined the effect of heavy elements pollution on the food uptake of the most common foraminiferal species of the Baltic Sea, E. excavatum which was a subject of several previous studies. Therefore, Baltic Sea seawater was enriched with
