Uslijed rada industrije, velike koncentracije prometa i individualnih ložišta, na području grada Tuzle već je dulje vrijeme prisutan problem onečišćenja zraka. Tvari koje onečišćuju okoliš predstavljaju rizik za zdravlje ljudi i drugih živih bića, a onečišćenje zbog sagorijevanja fosilnih goriva je na vodećem mjestu crne ljestvice prijetnji za zdravlje. Onečišćenost okoliša može uzrokovati niz bolesti, poput astme, alergija, raznih oblika raka, bolesti srca i krvožilnog sustava, problema s plodnošću, neuroloških problema i slično. <br /> U ovom radu prikazani su rezultati monitoringa emisije polutanata u razdoblju od 1. 1. 2019. do 31. 12. 2019. godine. Proveden je monitoring zraka za polutante: sumporov dioksid (SO<sub>2</sub>), dušikov dioksid (NO<sub>2</sub>), ugljikov monoksid (CO), ozon (O<sub>3</sub>) i lebdeće čestice PM<sub>2,5</sub>, na tri lokacije u Tuzli.<br /> Rezultati ukazuju na to da je tijekom sezone grijanja, odnosno zimskih mjeseci kvaliteta zraka u urbanom području grada Tuzle vrlo loša. Najveća koncentracija sumporova dioksida zabilježena je u prosincu na mjernoj stanici Bukinje i iznosila je 271,7 µg m<sup>–3</sup>, također u istom mjesecu, na mjernoj stanici Skver zabilježena je koncentracija lebdećih čestica PM<sub>2,5</sub> od 153,2 µg m<sup>–3</sup>.

The aim of this study was to obtain the first insight into PAHs mass concentrations bound to airborne particulate matter (PM) in the mid Adriatic coast area of Croatia, and compare them with the PAH levels in Croatia’s urban central area. Relatively low values of PAH mass concentrations were measured in the coastal area, compared to the continental urban region of Croatia impacted by increased emissions due to intensive traffic, industry, and residential heating. A high PM10 contribution of four-ring PAHs (Flu and Pyr) at Martinska site indicated that wood burning heating as well as open fire events, including waste incineration, could be important emission sources of PAHs in the mid Adriatic coast region.

The sediment is modified by inorganic cementitious material, polymer bonding agent, and jute fibre. The results show that the sediment is preliminarily consolidated when the mixture ratio of activated sediment/cementitious binder/sand is 65/25/10. Compressive strength and softening coefficient of stabilized earth bricks is further improved by polymer bonding agent and jute fibre. SEM images and EDS spectral analysis indicate that there is indeed synergy among inorganic hydration products, polymer network and jute fibre to strengthen the sediment. Eksperimentalno su proučena mikrostruktura i svojstva stabilizirane zemljane opeke načinjene od sedimenta rijeke Huang He (Žuta rijeka). Sedimentu su pridodani anorganski cement, polimerno vezivo i jutena vlakna. Prema rezultatima sediment je prethodno konsolidiran kada je u smjesi maseni omjer aktiviranog sedimenta, cementa i pijeska 65 : 25 : 10. Tlačna čvrstoća i koeficijent omekšivanja stabilizirane zemljane opeke dodatno su poboljšani polimernim vezivom i jutenim vlaknima. Snimke SEM-om i analiza EDS-om pokazuju da u očvršćivanju sudjeluju anorganski hidracijski produkt, polimerna mreža i jutena vlakna.

The part on which water flowed is barely corroded, whereas the moist part near the pouring joints is seriously corroded. We first studied the mechanism of this phenomenon by chromatography, X-ray diffraction, and energy-dispersive X-ray spectroscopy. We then used simplified models built by particle flow code software (i.e., particle flow code in three dimensions, PFC3D) to analyse how increasing degradation depth affects compressive strength and failure patterns. The results were as follows. (1) Gypsum and calcite in corrosive water were supersaturated. The part on which water flowed was protected by the crystallized precipitation on the concrete. By contrast, the degradation of the part where water flowed through pouring joints was aggravated by internal crystallization and dissolution. (2) PFC3D numerical simulation indicated that decreases in vertical ultimate stress were strongly linearly correlated with degradation depth. As for the −355.5 m damaged part, reinforcement should be conducted before degradation depth reaches 250 mm. (3) No obvious signs were observed prior to the failure of the corroded sidewall. Therefore, the development of degradation depth should be monitored before degradation parts are reinforced. U pomoćnom oknu rudnika ugljena Tong-ting u pojasu temeljne stijene pojedini dijelovi zida pokazuju različite stupnjeve propadanja. Područja na kojima je tekla voda malo su korodirana, dok su vlažni dijelovi uz izljeve izrazito korodirani. Mehanizmi te pojave najprije su proučavani kromatografijom, rendgenskom difrakcijom i energijski disperzivnom rendgenskom spektroskopijom. Veza između dubine korozije i tlačne čvrstoće te obrasca sloma analizirana je pojednostavljenim modelom utemeljenim na kôdu toka čestica (kôd toka čestica u tri dimenzije, PFC3D). (1) Voda je prezasićena s obzirom na gips i kalcit. Dijelovi preko kojih je voda tekla zaštićeni su precipitatom na betonu. Nasuprot tome, propadanje je pojačano kristalizacijom i otapanjem u nutrini izljeva. (2) Numerička simulacija modelom PFC3D pokazuje linearnu vezu između smanjenja vertikalnog maksimalnog naprezanja i dubine degradacije. Oštećeni dio na −355,5 m trebat će pojačati prije nego korozija dopre do 250 mm dubine. (3) Nisu bili uočeni jasni pokazatelji propadanja prije sloma korodiranog zida. Stoga treba pratiti napredovanje propadanja prije nego uništeni dijelovi budu ojačani.

They entrust the respective economic activity to 208 private and public companies specialized in waste collection and treatment. Organised waste collection affects 99 % of the population. The mixed waste from households and enterprises is at various frequencies collected at the door (kerbside collection) and transported by truck to a landfill, or processing plant. This article aims to estimate fuel consumption and fuel-related airborne emissions from the collection of mixed municipal waste in Croatia in 2013. The input data and emission results are shown for Croatia and each Croatian county, in total, and relative to the number of inhabitants and mass of collected waste. Annual consumption of diesel for the collection of mixed waste is estimated at 10.6 million litres. At the county level, fuel consumption ranges from 87 thousand litres to 2.2 million litres, on average 504 thousand litres per county. Total emission of CO2 is estimated at 28 000 t, which at county level ranges from 231 to 5711 t. Relative emission ranges from 3.3 to 13 kg CO2 per capita (average 6.6 kg per capita), or 8.6–28.1 kg t −1 of municipal waste (average 17 kg CO2 per ton of municipal waste). The average values of CO2 emission from MSW collection that should also be the target values are 7–9 kg for mixed waste, and 8–15 kg CO2 for separate waste streams. Apart from CO2 emission, this research estimates emission of other, diesel combustion related compounds, such as NOx, CO, lubricant related CO2, NMVOC, PM, f-BC, N2O, SO2, NH3, Pb, ID[1, 2, 3- cd]P, B[k]F, B[b]F, B[a]P), as well as total distance of transport.

(2) PFC3D numerical simulation indicated that decreases in vertical ultimate stress were strongly linearly correlated with degradation depth. As for the −355.5 m damaged part, reinforcement should be conducted before degradation depth reaches 250 mm. (3) No obvious signs were observed prior to the failure of the corroded sidewall. Therefore, the development of degradation depth should be monitored before degradation parts are reinforced. U pomoćnom oknu rudnika ugljena Tong-ting u pojasu temeljne stijene pojedini dijelovi zida pokazuju različite stupnjeve propadanja. Područja na kojima je tekla voda malo su korodirana, dok su vlažni dijelovi uz izljeve izrazito korodirani. Mehanizmi te pojave najprije su proučavani kromatografijom, rendgenskom difrakcijom i energijski disperzivnom rendgenskom spektroskopijom. Veza između dubine korozije i tlačne čvrstoće te obrasca sloma analizirana je pojednostavljenim modelom utemeljenim na kôdu toka čestica (kôd toka čestica u tri dimenzije, PFC3D). (1) Voda je prezasićena s obzirom na gips i kalcit. Dijelovi preko kojih je voda tekla zaštićeni su precipitatom na betonu. Nasuprot tome, propadanje je pojačano kristalizacijom i otapanjem u nutrini izljeva. (2) Numerička simulacija modelom PFC3D pokazuje linearnu vezu između smanjenja vertikalnog maksimalnog naprezanja i dubine degradacije. Oštećeni dio na −355,5 m trebat će pojačati prije nego korozija dopre do 250 mm dubine. (3) Nisu bili uočeni jasni pokazatelji propadanja prije sloma korodiranog zida. Stoga treba pratiti napredovanje propadanja prije nego uništeni dijelovi budu ojačani.

They entrust the respective economic activity to 208 private and public companies specialized in waste collection and treatment. Organised waste collection affects 99 % of the population. The mixed waste from households and enterprises is at various frequencies collected at the door (kerbside collection) and transported by truck to a landfill, or processing plant. This article aims to estimate fuel consumption and fuel-related airborne emissions from the collection of mixed municipal waste in Croatia in 2013. The input data and emission results are shown for Croatia and each Croatian county, in total, and relative to the number of inhabitants and mass of collected waste. Annual consumption of diesel for the collection of mixed waste is estimated at 10.6 million litres. At the county level, fuel consumption ranges from 87 thousand litres to 2.2 million litres, on average 504 thousand litres per county. Total emission of CO2 is estimated at 28 000 t, which at county level ranges from 231 to 5711 t. Relative emission ranges from 3.3 to 13 kg CO2 per capita (average 6.6 kg per capita), or 8.6–28.1 kg t −1 of municipal waste (average 17 kg CO2 per ton of municipal waste). The average values of CO2 emission from MSW collection that should also be the target values are 7–9 kg for mixed waste, and 8–15 kg CO2 for separate waste streams. Apart from CO2 emission, this research estimates emission of other, diesel combustion related compounds, such as NOx, CO, lubricant related CO2, NMVOC, PM, f-BC, N2O, SO2, NH3, Pb, ID[1, 2, 3- cd]P, B[k]F, B[b]F, B[a]P), as well as total distance of transport.
