“…Increased pressure and temperature alter the physical and chemical characteristics of the resulting sediment, which is metamorphosed into coal. Due to the heterogeneity of plant tissue and varying geochemical conditions, the structure of coal will differ between coal seams (Kirby et al, 2010). Coal is mainly composed of organic carbonaceous matter, noted as macerals and inorganic minerals in various proportions.…”

The Istrian coal mines, located in the eastern part of the Istrian Peninsula (Northern Adriatic Sea, Croatia) had by far the most important and economically the most valuable deposits of the anthracite coal reserves in Croatia since the 18th century until the year 1999, when their excavation and use in the coal-fired power plant Plomin ceased. The coal is found within the Palaeocene Kozina limestone beds. Four coal basins, Karojba, Sveti Martin, Pićan, and the Labin basin, hosted seven coal mines, e.g. Tupljak, Potpićan, Kozljak, Štrmac, Raša, Ripenda, and Krapan. The coal has been generally known under the name of Raša coal. It is exceptional in world terms due to its high content of organic sulphur, which can be up to 14%. Herewithin, this paper reviews Croatian scientific publications devoted to various aspects of Raša coal, along with the most important publications on either similar coals or relevant subjects worldwide. A brief introduction deals with the role of coal in electricity production, and the history of coal mining in Istria. The following chapter summarises current knowledge of the coal sulphur geochemistry, with several examples of high-sulphur coals from India and China. It is followed by the geological, geochemical, and physical characterisation of Raša coal. Since perturbations to ecosystems caused by coal combustion have been documented in numerous papers from a number of countries, Croatian studies carried out to determine the impact of Raša coal combustion on the local environment are also presented.

“…Increased pressure and temperature alter the physical and chemical characteristics of the resulting sediment, which is transformed into coal. Due to the heterogeneity of plant tissue and varying geochemical conditions, the structure of coal will differ between coal seams (Kirby et al, 2010). Almost all the elements of the Chemical Periodic Table can be found in coal.…”

Human health, the environment, and climate are being profoundly aff ected by complex pollutant interactions in the atmosphere. Almost all human activities cause the emissions of air pollutants. Their understanding and quantifi cation is the fi rst step towards the control and mitigation of air pollution. The general aim of this paper is to summarise the fi ndings of selected Croatian and Indian papers addressing air pollution, particularly those focusing on sulphur and aerosols associated with coal-fi red power plants. The two countries are essentially diff erent regarding their size, geography, history, economy, industrial potential, to name but a few. However, they both have had certain relations to the fossil fuel extraction and its usage in power stations and industry for decades. Various research approaches are presented, together with a brief outline of national air pollution policies.

“…Subsequent changes in temperature with depth under overlying strata and pressure modify the physical and chemical characteristics of the sedimentary environment, during which the peat transforms into lignite and higher-ranking coals. Variations in geochemical conditions and the heterogeneity of plant tissues contribute to different coal types (Kirby et al, 2010), which comprise varying proportions of macerals (organic components) and inorganic minerals. The primary maceral groups are the huminite to vitrinite, exinite or liptinite, and inertinite groups (Stach et al, 1982;Diessel, 1992;Taylor et al, 1998;Speight, 2013;Flores & Moore, 2024).…”

This study investigates the carbon (δ13Corg) and nitrogen (δ15N) isotopic composition of tertiary lignites and coals from six sedimentary basins: Velenje, Mura-Zala, and Zasavje in Slovenia; Sokolov in Czech Republic, Barito in Indonesia; and Istria in Croatia. The aim is to investigate the correlation between the fine detrital (fD) component and δ13C and δ15N in Velenje lignite samples. Additionally, we aim to evaluate the biogeochemical processes of organic substances during their deposition in all analyzed samples, calculate their δ13CCO2 values and compare the analyzed values of δ13C and δ15N to those reported in the literature. Thirty-two samples were analyzed, predominantly from the Velenje ortho-lignite (Pliocene), with additional lignites and coals from the Pannonian to Paleocene epochs for comparison. Carbon isotopic composition (δ13Corg) ranged from -27.9 to -23.6 ‰, and nitrogen isotopic composition (δ15N) ranged from 1.8 to 7.4 ‰. The fine-detrital lithotypes of the Velenje ortho-lignite exhibited the most negative δ13Corg values due to anaerobic bacterial activity in an intramontane alkaline lake environment influenced by the carbonate hinterland. Moreover, gelification processes affected fine-detrital organic matter more than larger wooden pieces. Terbegovci, Hrastnik meta-lignites, and Barito sub-bituminous coal also displayed low δ13Corg values, indicating limited gelification, while variations in the δ15N values suggested differences in mineralization. The Velenje xylitic lithotypes have higher δ15N values, indicating a more intense mineralization under aerobic conditions. Raša ortho-bituminous coal, deposited in a brackish environment, displayed the highest δ13Corg values and a wide range of δ15N values due to fluctuating water tables in a paralic carbonate platform environment. The lowest δ15N value was observed in the Sokolov Basin lignite coal, indicating minimal mineralization and low bacterial activity. The isotopic composition of CO2 in air (δ13Cair), which was calculated using the δ13C values in lignites and coal, ranged from -8.4 to -3.4 ‰, with Velenje lignite displaying the minimum value and Raša coal showing the maximum value. The determined δ13C and δ15N values of the coal and lignite samples in this research fall within the typical range of world coals.
