Mercury and its Future in the Czech Republic
Navrátil, Tomáš ; Vytopilová, M. ; Vlčková, Š. ; Mrázová, K. ; Zakharov, S. ; Honsová, Š. ; Pelclová, D.
Toxicity of mercury has been discussed for many years by specialists as well as by laymen. Legislative tools connected with measures and conditions concerning the trade, manufacture, use and interim storage of mercury, mercury compounds, mixtures, mercury-added products and the management of mercury waste are currently being prepared. Some suggestions and prepared measurements are mentioned and discussed in this contribution. Of course, it is necessary to differentiate among various forms of it, i.e., metallic form, vapors, amalgams, soluble and insoluble inorganic and organic compounds.

Information on Several Interesting Case Reports of Liquid Mercury Intoxication
Navrátil, Tomáš ; Vlčková, Š. ; Mrázová, K. ; Nováková, Kateřina ; Zakharov, S. ; Honsová, Š. ; Pelclová, D.
This contribution reports on several mercury non-professional intoxications. It can be summarized that it is very important to differentiate among forms of mercury which can (acute or chronic) endanger human health. Contrarily to the wide spread fears, liquid mercury represents low danger for men and for environment. Solid amalgams are probably the less toxic forms of mercury compounds. On the other hand, widely spread daily consumer goods can be very dangerous and toxic (saving balls, fluorescent tubes, etc.). Moreover, these goods are not marked as “toxic mercury containing”. The article discusses the instruction for removing mercury from our environment. Most of the reported data are based on database of the Czech Toxicological Information Centre (TIC) (from the years 1995 – 2015).

Continuous Glucose Monitoring by Real Time Sensor in Interstitial Fluid
Honsová, Š. ; Navrátil, Tomáš
The aim of this contribution is to compare the differences between accuracy claimed by the manufacturer in continuous glucose monitoring using the MiniMed Paradigm REAL-Time system with the results obtained in a patient during physical activity. Electrochemical glucose sensor measures the glucose oxidase reaction products. Measurement accuracy was determined using Clarke Error Grid analysis. It can be concluded that in the normal glucose range (4.4 to 10.0 mmol/ l) was more accurate than the measurements given by the manufacturer, in the opposite case; hyperglycemia is less precise than declared.

Evaluating the accuracy of continuous glucose monitoring by the patient through continuous glucose error grid analysis
Honsová, Š. ; Navrátil, Tomáš
The aim of the study is to compare the difference between the accuracy declared by the producer of continuous glucose determination using the MiniMed Paradigm REAL-Time system with the results achieved by patients in real life. The glucose sensor evaluates the catalytic transformation of glucose (enzyme glucose dehydrogenase) to hydrogen peroxide, the concentration of which is electrochemically evaluated. The accuracy of measurements was determined by Clarke Error Grid Analysis. It can be concluded that in normal glyceamia (4.4 to 10.0 mmol/l) the measurements realized by the parients are more accurate that it is supposed by the producer, opposite to the cases of hypoglycaemia or hyperglycaemia.
