Diatoms play a key role in the functioning of streams, and their sensitivity to many
environmental factors has led to the development of numerous diatom-based indices used …

The persistence of silver nanoparticles in aquatic environments and their subsequent impact
on organisms depends on key transformation processes, which include aggregation …

Background Microalgae play a key role in ecosystems and are widely used in ecological
status assessment. Research focusing on such organisms is then well developed and …

Extracellular polymeric substances (EPS) form an interface between microalgae and the
surrounding water environment. Copper (Cu) and zinc (Zn) are essential micronutrients but …

Although it has been well established that different species of marine algae have different
sensitivities to metals, our understanding of the physiological and biochemical basis for …

Cysteine (Cys) plays numerous key roles in the biogeochemistry of natural waters. Despite
its importance, a full assessment of Cys abiotic transformation kinetics, products and …

The uptake of mercury by microorganisms is a key step in the production of methylmercury, a
biomagnifiable toxin. Mercury complexation by low-molecular-weight (LMW) thiols can affect …

Various biomonitoring approaches were tested in the field to assess the response of natural
periphythic algal communities to chronic metal contamination downstream from an …

With the increasing use of nanotechnologies, it is expected that nanomaterials end up in
natural aquatic systems, from freshwater to the sea. In this work we studied the chemical …

Cell suspension cultures of red spruce (Picea rubens Sarg.) were selected to study the
effects of cadmium (Cd) and zinc (Zn) on phytochelatins (PCs) and related metabolites after …
