The objective of the paper was to learn about behavioural consumer preferences with regard to organic products distribution on the area of Małopolskie Voivodeship. The research studies covered purposefully selected a 100-person group of respondents. On account of the growing awareness of consumers concerning healthy food, they will even more often reach for organic products. Thus, the process of their distribution should be properly prepared so that the demand for this kind of food is the highest. The investigated respondents use a previously prepared shopping list and carefully read available products while shopping. Majority of them look for loose products. A proper quality of products and form of sale may increase the consumers' interest and consequently their distribution. ...
The main purpose of the paper was to determine the influence of catchment management on the bottom sediments quality of small water reservoirs as well as to determine toxic metal content in rushes. Samples of bottom sediments were collected in winter 2013 year, form 4 sediment layers (0-5, 5-10, 10-20 and 20-30 cm) at three points along the body of water. The 48 samples were collected. Soil material was prepared according to the procedures used in soil science, the analysis was performed for the fraction with a particle diameter of less than 1 mm. Plant samples from single species aggregations were randomly cut from 5 to 10 locations of 20-50 m2 area. From these samples the average composite sample was prepared. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after prior digestion in the mixture (5:1) of concentrated acids HNO3 (65%) and HClO4 (60%). Total Hg content was determined by the AMA 254 analyzer. Between the small water reservoirs adjacent to the areas where organic farming is used, and the reservoirs adjacent to the areas with mineral fertilization ...
The main purpose of this work was to determine the degree of negative impact of heavy metals accumulated in the water sediments to aquatic organisms. Samples of sediments were collected in winter 2013, from 4 layers of sediment (0-5, 5-10, 10-20 and 20-30 cm) at three points along the water reservoir. Sediments were prepared for analysis in accordance with the procedures applied in soil science. The analysis was carried out for the fraction with a particle diameter less than 1 mm. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after digestion in a mixture (5:1) of concentrated acid HNO3 (65 %) and HClO4 (60%). The total Hg content was obtained by using the AMA 254 analyzer. Only the lead content in the analyzed samples of bottom sediments exceeded the contamination value given by polish law (the Regulation of the Minister of Environment). According to the classification of PGI samples of sediments are classified mainly as medium polluted sediments (Class II), with the exception of zinc and lead concentrations (Class III). Due to the value of the indicator ...
Mamar is an artificial oasis that provides a base for natural resource conservation in West Timor. The uniqueness of Mamar is its application in arid natural environments through a sustainable local leadership system, and it has a positive impact ecologically, economically, and socially. However, the Mamar system needs to receive more attention from the government in conserving natural resources. Such studies like Mamar's have been conducted elsewhere in Indonesia under different names, but they were applied in areas with wet and relatively fertile climates. Also, research on Mamar has been carried out by several parties related to the function of Mamar economically and the condition and structure of Mamar physically and biologically. However, research on Mamar related to the Construction of Environmental Leadership with local community behavior in Mamar based natural resource conservation has never been done. This research aims to analyze the construction of environmental leadership in natural resource conservation practices based on the Mamar system. This research was conducted through qualitative methods and critical interpretive approaches, with data collection techniques in the form of observation and interviews. The results indicate that Mamar based natural resource conservation in West Timor has positively and significantly impacted social, economic, and ecological ...
