The problems of soil hygiene and contents of the following heavy metals: cadmium, cobalt and nickel in the productive parts of plants in the location of Agricultural Cooperative Štrba in Poprad County were discussed in the presented work. Above-mentioned location is found in the neighbourhood with a chemical factory Chemosvit Svit. The achieved results show that the soil hygiene in this region is mainly affected by the activity of this chemical factory. This factory is producing many risky substances and their results can be seen in the condition of soil hygiene and in the quality of farmed plants. The results of monitored heavy metals (Cd, Co, Ni) prove that the content of cadmium and nickel is the main polluting factor of soil in this region. The increased contents of these elements in soil produce a high risk of the uptake to plants. This further affects the technological quality along with the quality of hygiene of farmed products and finally the food itself as well. A higher attention needs to be paid to cobalt too, because it proved quite high cumulation ability in soil.

The results of studies of three sites of agrocenoses are presented: wheat (seed cereals), soybeans (legumes) and legume-cereal (rumpgoatskin) perennial grass mixtures to identify the peculiarities of the transition of stable and radioactive pollutants (including substances of hazard classes 1 and 2 and 137Cs) in the system "agro-chernozems – agricultural plants" with soil testing and quality control of aerial and underground plant phytomass. In this radioactively contaminated area, the elemental composition of wheat, soybean, rump and goatskin does not differ from the composition of the corresponding species in the background. Legumes have an increased need for alkaline earth metals (Ca, Mg, Sr) and also contain more Ni and Mn, cereals – in Si. Within the studied part of Plavsky radioactive spot, the quality of agricultural products meets the relevant standards for the content of heavy metals and 137Cs.

Abstract Background: Fish farming in Cameroon is growing very rapidly and fish available in the markets is mostly coming from fish farms, but domestic fish production is still low to meet demand. Intensification of production could lead to the occurrence of various types of contaminants that can affect the sanitary quality of farmed fish and consumer health. This study aimed to assess the quality of farmed fish collected in fish farms located in four regions of Cameroon (Center, South, West, Littoral).Results: Concentrations of arsenic, cadmium, lead, chromium, cobalt, and nickel were determined in pond water and muscles of Oreochromis niloticus and Clarias gariepinus raised in concrete and earthen ponds to evaluate health risk for consumers. Trace elements were determined using Inductively Coupled Plasma Optical Emission spectrometry (ICP-OES). Heavy metals in water for concrete and earthen ponds shows there are no significant differences (p<0.05) between the rearing systems except for cobalt and nickel. Heavy metals concentrations in water were lower when compared to the WHO recommended limits except for cadmium in all the ponds. For concrete ponds, heavy metal concentrations decreased in water in the sequence of Cd > As > Co > Ni > Cr > Pb. For earthen ponds the concentrations decreased as Cd > Co > As > Ni > Cr > Pb.Conclusion: Concentrations recorded in the muscles of the 2 species were above the safety limits recommended by FAO/WHO. The target hazard quotient of As was highest compared to other metals and higher than the acceptable limits according to US Environmental Protection Agency guidelines in all fish species. the level of each investigated metal, highlighted a very low health risk for consumers.

Background: We surveyed the quality of risk stratification politics and monitored the rate of entries to our company-wide protocol for venous thrombembolism (VTE) prophylaxis in order to identify safety concerns. Patients and methods: Audit in 464 medical and surgical patients to evaluate quality of VTE prophylaxis. Results: Patients were classified as low 146 (31 %), medium 101 (22 %), and high risk cases 217 (47 %). Of these 262 (56.5 %) were treated according to their risk status and in accordance with our protocol, while 9 more patients were treated according to their risk status but off-protocol. Overtreatment was identified in 73 (15.7 %), undertreatment in 120 (25,9 %) of all patients. The rate of incorrect prophylaxis was significantly different between the risk categories, with more patients of the high-risk group receiving inadequate medical prophylaxis (data not shown; p = 0.038). Renal function was analyzed in 392 (84.5 %) patients. In those patients with known renal function 26 (6.6 %) received improper medical prophylaxis. If cases were added in whom prophylaxis was started without previous creatinine control, renal function was not correctly taken into account in 49 (10.6 %) of all patients. Moreover, deterioration of renal function was not excluded within one week in 78 patients (16.8 %) and blood count was not re-checked in 45 (9.7 %) of all patients after one week. There were more overtreatments in surgical (n = 53/278) and more undertreatments in medical patients (n = 54/186) (p = 0.04). Surgeons neglected renal function and blood controls significantly more often than medical doctors (p-values for both < 0.05). Conclusions: We found a low adherence with our protocol and substantial over- and undertreatment in VTE prophylaxis. Besides, we identified disregarding of renal function and safety laboratory examinations as additional safety concerns. To identify safety problems associated with medical VTE prophylaxis and “hot spots” quality management-audits proved to be valuable instruments.

The purpose of this article is to present the correlation between management of an economic entity and the development of ethical accounting dilemmas in the era of high-risk business. In the globalisation era and recurring economic crises, realisation of the objectives of a company takes place under high risk conditions. It is therefore necessary to use a proper management system. The necessary condition for making all decisions is to have relevant information. The value and relevance of these decisions depend on the quality of information which they have been based on. Lack of ethics in accounting has a direct impact on the company's management, which is based on information generated by the accounting system of the company. Ethical dilemmas arising in accounting are also ethical dilemmas arising in the process of business management. 


Efficiency of combination of soil herbicide Command (CE 0.02 ml/m2) and growth stimulators Melafen and Emistim S for tobacco seedling growing in sheltered ground has been studied. Before studies inhibition properties of herbicide on first stage of tobacco growing were found. For decreasing effect of herbicide ’s depression and increasing growing processes researches during greenhouse and field stages have been carried. It has been found that soaking seeds in solution of growth stimulator Melafen (concentration 0.05 %) and Emistim S (concentration 0.00001 %) during 3 hours in combination with further treatments on basic stages of seedling development (cotyledon and ready for transplanting before pulling out) led not only to decreasing toxic effect of herbicide but also increasing qualitative properties of tobacco plants. Growth stimulators led to increasing length of plants from collar to growing point by 46-62 %, to end of tips - by 20-35 %, above ground plant mass - by 42 - 86 %, root mass - by 32 %. It was also noticed 28 - 36 % increasing outcome of standard seedlings from m2 in time of transplanting. Due to prolonged effect of Melafen and Emistim S seedlings transplanted into field were with increased surviving properties. Later, due to increased growing rate it was noticed increasing leaf area by 9-18 % and productivity - by 16-24 %. Economic effect due to utilizing growth stimulators Melafen and Emistim S during seedling stage reaches 360 and 470 rubles/m2 and during field stage - 66 and 98 th.rubles/ha respectively. Offered elaboration can be utilized for protecting systems of different agricultural plants where utilizing soil herbicides is recommended. Also quality of cured tobacco grown with stimulators had been improved.

No real improvement in the technological quality of beet has been recorded over the last 15 years in Northern Italy. Among the possible explanations for the quality stagnation is that the traditional formulae cannot correctly differentiate between sugarbeet varieties which produce thick juice of very high purity. This seems to be connected with the role of potassium. The use of a standard purification procedure gives reliable and accurate data which is immediately comparable with the factory data. Research projects on medium/long term storage are currently being performed by Co.Pro.B., Italy, in cooperation with Syngenta and Beta. Up to now the results have shown that storage of sugarbeet in autumn time in northern Italy is possible provided that suitable varieties and proper handling of the roots are employed. Results obtained in the storage trials are reported. Correlations have been found between quality parameters (purity, color and lime salts) of the purified juice with the glucose content of the raw juice. An interesting correlation is reported between purified juice purity and raw juice purity.

The paper evaluates the presence and content of traces of heavy metals Hg, Pb, Ni, Cd (total forms) from coal and solid combustion products, the degree of transfer and accessibility in the area of influence of a lignite power plant. The content of toxic heavy metals in residues are characterized by RE Meiji [ 1 (Pb and Hg) and REMeij �1 (Ni and Cd) for the filter ash. Pb and Ni content in the soil exceeds normal values, and Pb exceeds and alert value for sensitive soils around the residue deposit (70.20 mg.Kg-1). The degree of accessibility of the metals in plants (TF), reported at the Khan reference value (0.5), indicates a significant bioaccumulation level for the metals: Cd (1.9) and Hg (0.6) inside the deposit; Cd (0.39) at the base of the deposit, Hg (0.8) in the area of the thermal power plant. The trace levels of heavy metals analyzed by GFAAS and CVAAS (Hg), indicates a moderate risk potential for food safety and quality of life in the studied area.
