“…The CR Armed Forces (AF) are systematically and in the long term prepared not only for the fulfilment of tasks in military operations conducted outside the territory of the CR, but also for non-military operations taking place within the state [1]. The declared commitments of the CR AF in relation with assistance operations in support of the Integrated Rescue System (IRS) may be carried out for rescue work in disasters or in other serious situations endangering lives, health, property values or the environment if administrative authorities, local authorities and the basic components of the IRS cannot provide rescue work by their own forces [2][3][4][5][6][7]. It follows that all soldiers, without distinction of a branch and membership to a unit (formation, brigade level formation or facility), can be used in cases of disturbance of industrial infrastructure objectives [8][9][10][11].…”

The Czech Armed Forces' soldiers of all specializations and mainly the chemical corps'specialist are prepared for task fulfillment in military and non-military operations within those a real threat of weapons of mass destruction employment and, occasionally, the real danger of toxic industrial materials leakage is present. They can solve problems caused by acids leakage in contaminated areas mainly during task fulfillment in non-military operations on the Czech Republic territory in cooperation with Fire Rescue Brigades' chemical specialists. Individual protective equipment which is established in the Czech Armed Forces were neither design for this purpose and, moreover, nor tested and thus there is no real data concerning their chemical resistivity. In recent time, some methods have been introduced into the Czech Armed Forces environment. They are useful for determination of chemical resistivity of barrier materials against toxic compounds detectable with acid-basic (colorimetric) methods and conductometric ones. The paper deals with the possibility of using the presented methods and compares the suitability of their application in relation to the protective garments designated for the Czech Armed Forces members' body surface.

“…Studies on the cosmetics or on their components stability usually include and focus on different accelerated storage conditions under which the samples are kept, in elevated temperature (37, 40 or 45 °C), during different periods of time (1 to 3 months), depending on the product type [24][25][26][27][28][29]. In this study, the aspect, color, fragrance, pH and density were monitored in conditions of temperature variation from 5 to 40 °C, during a period of 2 months.…”

The products used in cosmetic formulations are continuously diversifying as a result of researches in the field, which combine the healing and prevention of many skin conditions with the use of natural products such as vegetable extracts and essential oils. Testing the stability and compatibility of new or modified cosmetics is required to ensure that quality standards are met when stored in proper conditions for functionality and aesthetics, to preserve their chemical, microbiological and physical properties. In this study, the stability and compatibility of a new cosmetic product containing lavender essential oil in plastic container-plastic jar 100 mL PPH Polypropylene homopolymer (Moplen HP648T) is tested against the glass receptacle used as a control. The monitored parameters were organoleptic characteristics (appearance, color, fragrance), physicochemical (pH, density), under controlled temperature conditions, and the microbiological ones. The results of this study showed that the tested cosmetic product is compatible with the plastic container; data obtained were comparable with the organoleptic and physicochemical test results obtained in the case of the control sample stored at room conditions.

“…From the results showed above is deducted that by the two types of electrochemical methods using screenprinted carbon electrodes (DPV and CV) and Jenco microelectrodes (for iodide detection), iodide can be easily determined qualitatively and quantitatively. Both methods are safe and easy to use, and can be thought of as a portable system with a wide range of applicability [34][35][36][37][38][39][40] (screen electrodes are already used to detect toxic and bioactive compounds in the life sciences), alongside other validated methods for the same purpose [41][42][43][44][45][46][47]. Redox microelectrodes correlate in a good manner the redox status of the solution with KI concentration.…”

Iodine is a micronutrient of high importance for the health and good development of individuals. It is contained in many foods, but it is also part of the chemical component of oceans and soil. Its deficiency is still a problem of humanity, which has a serious repercussion on our health. It is therefore important to have specific, fast and cost effective methods of iodine detection from different samples. This work aims to identify optimal parameters for potassium iodide (KI) detection from different media, to be further applied to real samples: plant extracts, water, biological fluids. Results showed a significant difference in electrochemical results, depending on the pH values of the mixture and also on the time which influences the compounds stability. Differential pulse voltammetry and cyclic voltammetry using carbon printed sensors, as well as microsensors for redox status or direct iodide detection are important analytical tools which have a wide range of applications in the food, medicine, toxicology and other domains.
