This review describes the features, importance and current state of analytical techniques used for the determination of antimony based on separation, optical, static and dynamic electrochemical principles. Antimony is an environmentally important element coming from industrial activities as well as from eroded deposits of metal ores. It may enter food chain and have toxic effects on human; hence its monitoring is necessary today. The most common analytical technique for the detection is atomic absorption spectrometry, which is however quite expensive. Therefore, novel techniques based on electrochemistry are being developed, because they are cheap, fast, and do not involve any complicated sample pretreatments.
Fluorides may enter into human body with drinking water, food and also with fluoridized salt. Fluorides play a crucial role in osteoporosis treatment. They are essential in normal development of teeth and bones. However, at high concentrations fluorides are toxic causing fluorosis, osteosclerosis and failure of kidneys. This is why more sophisticated methods for their monitoring are developed. This review describes the features, importance and current state of analytical techniques used for determination of fluorides by optical and electrochemical methods.

The review deals with osmium tetroxide, a very toxic volatile substance. It can be misused as a chemical weapon intoxicating by inhalation in closed space with limited air circulation (airports, shopping centres). In contrast, osmium tetroxide is very important compound in analytical chemistry especially in electron microscopy and DNA labelling in biophysical chemistry. Some analytical techniques for its detection are discussed with an emphasis on voltammetric methods.
