1. New single particle methods for detection and characterization of nanoparticles in environmental samples
Abstract : Nanoparticles (NP) are being used in rapidly increasing quantities which has resulted in concerns about possible harmful effects for health and environment. NP are already undergoing similar risk assessment programs as conventional chemicals, and due to their enhanced surface reactivities it has been proposed that the use of NP should be regulated by specific legislation based on particle size.

2. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins
Abstract : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. READ MORE

3. Analysis, metabolism, effects and biological monitoring of N-methyl-2-pyrrolidone
Abstract : N-methyl-2-pyrrolidone (NMP) is an organic solvent widely used in the industry. Irritation of the eyes and in the respiratory system has been reported after occupational exposure to low air levels of NMP. The EU has also classified it as a developmental toxicant. NMP is easily absorbed in the gastrointestinal tract and airways and through skin. READ MORE

4. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems
Abstract : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. READ MORE

5. Electrochemical detection of trace metals: from traditional techniques to new ultrathin membrane electrodes
Abstract : Accurate detection of trace metals in environmental waters is an analytical challenge that is still open for the time being. The current state of the field reveals the predominance of the so-called hanging mercury drop electrode (HMDE) for multi-metal detection by means of anodic stripping voltammetry (ASV) readout.
