Quantities, environmental footprints and beliefs associated with household food waste in Bosnia and Herzegovina.

The objectives of this research were to identify the quantities and global warming, acidification and eutrophication potentials associated with household food waste in Bosnia and Herzegovina. In parallel, this study investigated perceptions related to food waste and using the quality function deployment for environment model, correlated reasons for discarding food waste and beliefs associated with food waste. Based on this study, it is estimated that around 2.8 kg of food waste is disposed of by the average household every week. Global warming, acidification and eutrophication potentials associated with household food waste are, on average, 3.49 kg CO2e/week, 2.42 g SO2e/week and 8.70 g PO4e/week, respectively. Also, Bosnian households discard over 80 different pieces of food packaging waste weekly, where plastic packaging is the most dominant packing type. The highest ranked reason for discarding food is linked to plate leftovers. In general, Bosnian citizens feel guilty when they waste food.

The influence of tobacco blend composition on carbon monoxide formation in mainstream cigarette smoke.

The aim of this study was to examine the impact of three main tobacco types (flue-cured FC, air-cured AC and sun-cured SC) and two tobacco-based materials (reconstituted tobacco - recon RT and expanded stem) on the formation of carbon monoxide (CO) in the gas phase of mainstream cigarette smoke. The results showed that the type of tobacco examined had a significant impact on the amount of carbon monoxide production in the gas phase of cigarette smoke. AC and SC tobaccos had the most evident impact. The amount of tobacco in mixtures M1, M2 and M3 as well as the addition of expanded stems had an impact on the amount of CO formed in the cigarette smoke. There is weak correlation between CO content in the smoke and the chemical composition of the tobacco. Draw resistance had an impact on CO production. The research results are of great importance, since tobacco selection is the first step in the production of cigarettes with reduced emission of harmful elements contained in the smoke.
