Model for management of environmental impacts from flooring's production processes by the application of life cycle assessment (LCA)

U disertaciji je predložen opšti model za upravljanje uticajima na životnu sredinu u okviru proizvodnih procesa proizvodnje podnih obloga, zasnovan na metodi ocenjivanja životnog ciklusa proizvoda i procesa. Model je sistematično predstavljen kroz opis osnovnih delova - modela inventara životnog ciklusa i modela za ocenjivanje uticaja životnog ciklusa. Disertacija sadrži i detaljan opis podloga na kojima je model razvijen. Verifikacija razvijenog modela je sprovedena kroz tri studije slučaja.The dissertation proposes a general model for managing environmental impacts within the manufacturing process of flooring coverings, based on the method of life cycle assessment of products and processes. The model is systematically present by describing the main parts - the life cycle inventory model and a model for the life cycle impact assessment. Dissertation contains a detailed description of the background bases on which the model is developed. Verification of the model is carried out through three case studies

Toxicological assessment of honey from conventional and organic production and risk assessment for public health

Honey has become a focal point of concern due to the potential presence of pesticide residues originating from agricultural practices. This study undertakes a comprehensive toxicological assessment of pesticide residues in conventional and organic honey, as well as a risk assessment employing estimated daily intakes (EDIs) in the evaluation of the potential risks of these agrochemicals to public health. A total of 200 honey samples originating from conventional and organic producers were collected and analyzed by a Quick Easy Cheap Effective Rugged Safe method (QuEChERS). Analysis of organic honey didn’t detect any residue of investigated pesticides. The most detected pesticides in conventional honey samples were boscalid (0.01 μg/kg), and coumaphos ranging between 0.012 μg/kg to 0.016 μg/kg, respectively. Detected pesticides such as acetamiprid, pyraclostrobin, thiacloprid, and azoxystrobin were under the reporting level (RL). Results obtained by EDI indicated that all investigated honey samples are safe for human consumption. In conclusion, this research contributes to the understanding of the toxicological implications of pesticide residues in both conventional and organic honey consumption. By delineating the potential health hazards associated with each type, this study aims to provide consumers, regulators, and beekeeping industries with valuable insights to make informed decisions that safeguard human health while promoting sustainable agricultural practices

An analysis of the profitability of the restitution of sessile oak forests affected by wildfires in Serbia

Wildfires caused by climate change in Europe have numerous and long-lasting ecological, economic, and social implications for sustainable development (natural environment, economy, and society as a whole). Artificial revitalization of sessile oak forests destroyed by wildfires in Serbia is feasible, but it is quite expensive compared to the spontaneous regeneration. Cost-benefit analysis (an economic approach to comparing and estimating the benefits and shortcomings of a particular business plan, i.e., an investment project by analyzing its costs and benefits) is aimed at finding the best solutions and making the best decisions about the desirability of a project. It was concluded that the investment in the restitution of sessile oak forests could be profitable only if it was based on wood production. Wood production may bear slightly higher interest rates compared to previous estimates which ranged mainly around 3%. This primarily applies to better site classes, while poor quality sites require lower rates. At lower discount rates, it takes more time to reach the break-even point, while the period of time needed to reach the break-even point shortens with higher discount rates. The length of the production cycle plays an important role in determining the investment profitability, especially regarding the relationship between the length of the production cycle and production targets (the type and the quality of wood assortments produced). According to the results of the analysis of intangible benefits and costs, the costs outweigh the benefits, which makes the restitution of sessile oak forests destroyed by fires unacceptable
