“…In general, these Fe and Ti contents were relatively higher than those of the report in the literature for other rivers (Fe in [8,9,28,29,[32][33][34], and Ti in [32,33]). Moreover, the Fe contents in the suspended sediment samples exceeded the environmental safety threshold, which is 20 mg/kg according to [35].…”

“…In general, these Cu, Zn, and V contents were relatively higher than those of the reports in the literature for other rivers (Cu and Zn [8,9,28,29,32,34] and V [8,34]). The values of Cu content were generally lower than the environmental contamination threshold, which is 110 mg/kg according to [36], except for samples C and D, which represent densely-populated tributaries in the southern part of Bandung.…”

“…Comparing the river sediment to that from elsewhere [5,8,9,[27][28][29], the values of χ LF in the Citarum River were relatively high. This is to be expected, as the samples used in the other studies were taken from a non-volcanic catchment area.…”

Variations in the Concentration of Magnetic Minerals and Heavy Metals in Suspended Sediments from Citarum River and Its Tributaries, West Java, Indonesia

Abstract:The Citarum River has a volcanic catchment area in West Java Province, and is one of the nationally strategic rivers in tropical Indonesia due to its roles in water supply and in power generation. The river is economically important, but it is also polluted by industrial, agricultural, and residential wastes. Suspended sediment samples were collected along a certain section of the Citarum River, starting in Balekambang through the area of Bandung Regency to the downstream village of Nanjung, where the river is dammed. Similar samples were also collected from seven tributaries of the Citarum River. Magnetic and heavy metal analyses show that unlike river sediments from a non-volcanic catchment area in temperate climates, magnetic susceptibility values tend to decrease downstream, showing that the magnetic minerals in the upstream area are mostly lithogenic in origin, containing more Fe-bearing minerals compared to those in tributary samples which are anthropogenic in origin. Anthropogenic pollution is also represented by the increase of Zn content along the river. The results suggest that applying magnetic methods for monitoring river pollution in the tropics or in the volcanic areas should be carefully analyzed and interpreted.

“…A paper [51] reviewed the environmental implications of selenium, and pointed out that rain can leach selenium from coal and oil-shale The collected sediment sample could be considered sewerage sludge due to its proximity to an effluent pipe ( Figure 1E). Table 2 shows that Pb, Zn and Cu levels are increased with respect to a geographically similar locality [28], and to the sediment quality criteria (data in Table 2). Although they seem to exceed the toxic levels, they are lower than the limit values for metals in sewerage sludge [45], as follows (mg/kg): Cu 1000-1750, Zn 2500-4000, and Pb 750-1200.…”

Selenium, Sulphur, Trace Metal, and BTEX Levels in Soil, Water, and Lettuce from the Croatian Raša Bay Contaminated by Superhigh-Organic-Sulphur Coal

This paper elaborates soil, water, and lettuce contamination status with respect to selenium, sulphur, trace metals, and BTEX (benzene, toluene, ethylbenzene, and xylenes) in a coal-based area (Raša Bay, Adriatic Sea, Croatia). A local coal-fired power plant polluted soil with S, Se, Cd, and PAHs due to the combustion of domestic superhigh-organic-sulphur coal. The locality is dotted with waste from coal mining/separation, coal combustion, former metal factories, untreated municipal and coal mine effluents, along with various harbour activities, which contribute to environmental contamination. The methodology involved ICP-MS and GC-MS for the measurement of trace elements and BTEX, respectively, while soil sulphur was determined with Eschka’s mixture. The max values of the analysed trace elements in soil (mg/kg) are reported: Hg 1.14, Cd 3.29, V 624, Se 10.3, Pb 872, Cr 1860, Zn 6580, Cu 1850, and U 25.2. According to ecological indices, these values fall into the category of an extremely high level of soil pollution. Elevated total Se values in surface water are ascribed to leaching of seleniferous coal, ash, and coal-polluted soil. Levels of BTEX in water samples were very low (0–0.83 µg/L). The data provide basic information on the inorganic and organic contamination status of the Raša Bay area.

“…Regarding the geological, hydrological and hydrographical setting, more details can be found elsewhere (Durn et al, 1999;Peh et al, 2010;Halamić et al, 2012;Frančišković-Bilinski et al, 2014). Briefly, the most prominent geological characteristic of the study area is the karst topography and carbonate bedrock.…”

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.
