Opis:: The aim of this study has been to make an analysis and evaluation of iodine content in running surface waters in protected landscape areas (PLA) in the Czech Republic. Water samples were taken in 2009-2011 in Jeseníky PLA (Rapotín locality) and in Šumava PLA (Arnoštov and Lipno localities), and in 2009-2010 in the upper course of the Blanice River and its tributaries in and outside of Šumava PLA. Iodine was determined by the ICP-MS method. The average iodine content was 1.55±0.33 μg dm-3 (n = 41) in Jeseníky PLA and 2.58±0.33 μg dm-3 (n = 24) and 2.29±0.84 μg dm-3 (n = 30) in Šumava PLA. The average iodine content in water samples of the Blanice River and its tributaries localized in Šumava PLA was 2.27±0.65 and 2.38±0.66 μg dm-3 and outside of Šumava PLA it equalled 2.90±0.68 and 3.26±1.51 μg dm-3. The lowest concentration of 1.43 μg dm-3 was found out in a sample from the Spálenecký brook (Šumava PLA), and the highest one, 7.63 μg dm-3, was determined in a sample from the Živný brook, which flows below the town Prachatice. Higher concentrations were measured in the summer season: 3.05±0.35 (Blanice) and 3.63±1.24 μg dm-3 (tributaries), while lower ones were determined in the spring season: 1.48±0.30 (Blanice) and 2.37±1.12 μg dm-3 (tributaries). The results confirm the low iodine content in the environment of Jeseníky and Šumava Mts., and the self-purification capacity of the Blanice River even when it is stressed with anthropogenic iodine.

Opis:: Iodine is an essential trace element for animals. The major sources of iodine for animals are contained in feed and water, in which the iodine content depends on its amount in the given environment. The aim of this study was to analyse and evaluate the iodine content in soil, soil water, grass mass, and also to assess the effect of grassland exploitation on the iodine content in the Šumava and Jeseníky Protected Landscape Areas (PLAs) in the Czech Republic. The soil type in both PLAs was Modal Cambisol. Soil samples were collected from two different depths (up to 15 cm, 16-30 cm). Soil water samples were extracted from a depth of 40 cm and grass mass samples were collected from an area of 1 x 1 m. The areas according to exploitation intensity were as follows: EA1 – a meadow mowed twice a year, EA2 – a meadow mowed once a year, EA3 – a meadow was not mowed for 5 years. Iodine in soil and grass mass was determined by a spectrometric method (the Sandell-Kolthoff reaction). Iodine in water was measured by the ICP-MS method. The average iodine content in the Jeseníky PLA was 0.91±0.18 mg kg−1 in soil, 1.16±0.79 µg dm-3 in soil water and 0.16±0.07 mg kg-1 of 100% DM of grass and in the Šumava PLA was 4.69±0.70 mg kg-1 in soil, 3.12±0.91 µg dm-3 in soil water and 0.31±0.13 mg kg-1 of 100% DM of grass. A significantly (p<0.01) higher iodine content in soil (5.14±0.55 mg kg−1) was recorded in the most exploited EA1 area. The iodine content in soil water was significantly higher (p<0.05) in the EA2 area. The iodine content in grass mass was not affected by the exploitation of grassland. Significant differences in the iodine content extracted from the two soil depths mentioned above were not observed. The results demonstrated a low iodine content in both PLAs in the Czech Republic (especially in the PLA Jeseníky) and demonstrate complex relationships among individual components of the soil ecosystem affecting iodine bioavailability. The findings also indicated that exploitation may be another factor that can influence the iodine content in soil.

Opis:: Artykuł dotyczy występowania czynów niedozwolonych oraz innych form przestępczości przeciwko środowisku na uczelniach publicznych odnoszących się do funkcjonowania obiektów tego rodzaju. Artykuł koncentruje się również na zastosowaniu wybranych metod analizy ryzyka i oceny wpływu błędu ludzkiego jako czynnika ryzyka w procesie ochrony fizycznej osób i mienia w środowisku uczelni publicznych.
The article deals with the occurrence of illegal acts and other forms of crime in the environment of public universities (referred to as PU) relating to the operation of objects of this nature. The paper is also focused on the application of selected methods of risk analysis and the evaluation of the impact of human error as a risk factor in the complex process of physical protection of persons and property in the environment of public universities.
