Biosorption of heavy metals by microalgae: Hazardous side effects for marine organisms.

Biosorption is nowadays recommended as an ecological and environmentally friendly alternative to remove metals from contaminated regions. Even in situ incubations of algae on the seabed are conducted to investigate potential future ways of reducing metal contamination. Our study investigated the negative effects on microorganisms when metal-enriched algae are released into the marine environment.

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

Foraminifera are unicellular organisms and play a pivotal role in the marine material cycles. Past observations have shown that the species 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.
