“…The gaseous H 2 SO 4 rapidly partitions into already existing aerosols (or it may form new particles). Through long-range transport, H 2 SO 4 deposition contributes to the widespread acidification of ecosystems (Odén 1976, Calvert et al 1985. Sulfate aerosols efficiently scatter solar radiation, hence their increase in the atmosphere exerts a cooling effect on climate that masks some of the warming caused by increased greenhouse gases (Charlson et al 1991).…”

Key Words anthropogenic activities, effects on the atmosphere, stratospheric ozone depletion, photochemical ozone production, ozone hole, CH 4 , NO x , CO, HO x , ClO x s Abstract An overview is given of the main anthropogenic influences on the chemistry of the atmosphere. Industrial and agricultural activities have altered the chemical composition of the atmosphere in many important ways, which is reflected especially in the distribution and concentrations of ozone in the troposphere and stratosphere. On one hand, as a result of industrial chlorofluorocarbon emissions, ozone has been depleted in unexpected major ways in the polar stratosphere. On the other hand, especially as a result of NO emissions, tropospheric ozone has increased both in the industrial midlatitude regions and at low latitudes, in the latter mostly because of tropical biomass burning. In the future, growing anthropogenic emissions by developing nations will have an additional effect on the climate and the self-cleaning (oxidation) power of the atmosphere.

“…Among them, sulphur is a particularly interesting component, which, along with nitrogen and phosphorous, is an essential element for all living matter. Its characterisation, occurrence, ecotoxicology and environmental fate have been studied extensively using various scientific approaches (Oden, 1976;Zerklea et al, 2010;Senko et al, 2011;Kuklińska et al, 2013;Saikia et al, 2015;Sołek-Podwika et al, 2016). It is ubiquitously present on Earth, existing in soils, seawater and plants in organic, sulphate, and sulphide forms, whereas in gaseous and solid states in the atmosphere (Badr and Probert, 1994).…”

Abstract:The Labin City area has represented the major Croatian coal mining, metal industry and coal-fired electricity centre for more than two centuries. The domestic superhigh-organic-sulphur (SHOS) Raša coal is a unique variety compared to other coal types worldwide, based on its highest organic sulphur values, up to 11%. It was utilised in the Plomin coal-fired power plant during the period 1970-2000, and was replaced by an imported low-S coal afterwards. This paper presents the levels of S, Se, V, U, Hg, Sr, Cd, Cr, Pb, Cu and Zn in the two coal types, their bottom ash, seawater and plant (clover, mushroom and foliage) specimens collected from the Labin City area, while the sulphate was measured in surface stream water. Their levels were compared with relevant legislative as well as the published data from different world localities. Data analysis was interpreted in the context of past and recent coal combustion activities.

“…Therefore, coal seams containing more than 3% of total S are commonly associated with marine strata (Casagrande, 1977;Chou, 1997 Smith et al, 2011). Herewithin, from the late 1960s onwards, the major role of SO 2 in atmospheric pollution and the occurrence of acid rain has been widely recognised by an increasing number of researchers (Oden, 1976;Schindler, 1988 minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. Coal combustion processes in power plants also release ash, i.e.…”

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.
