The resistance of edible oils to oxidative degradation, leading to rancidification, is an important parameter for assessing the quality of oil. This paper presents a new promising method to diagnose the volatile compounds which are products of oil oxidation reactions. Our experiment was carried out using a combined method of UV irradiation as an oxidation acceleration technique, headspace solid-phase...
Growing public concern over protecting our environment obligates chemists, including analytical chemists, to change chemical activity in such a way that it will be conducted in an environmentally friendly manner. The article provides an overview of green chemistry issues relating to sample preparation techniques, concentrating especially on the green advantages of so-called solventless sample preparation...
This paper presents the tasks, procedures and instrumental trends in analytics and monitoring of air pollution. The classification of methods and analytical techniques used for atmospheric air studies are also discussed.
The paper presents the examples of application of plants for assessing the pollution degree of different elements of environment. First, the definition of bioindicators and biomonitors, the criteria for their selection for different purposes and advantages and disadvantages of this method of monitoring are given. The second part reviews the application of typical plants (algea, mosses, lichens, grasses,...
In this review the most well-known examples of secondary effects and pollutants which occur in the particular elements of the environment (atmosphere, hydrosphere, soil and food products) are described. Very often pollution of the environment is characterized only by quantities of primary pollutants emitted to the particular elements of the environment. However, it is much more difficult to find any...
