“…Considering China, Croatia, and India, the three countries are somewhat similar in terms of coal environmental legacy and selenium environmental distributions. Papers have reported low as well as high levels of environmental Se in different parts of the three countries, and some of them (high ones) are directly related to either (highly sulphurous) coal (Yang et al, 1983;Zheng et al, 1999;Zhu et al, 2001Zhu et al, , 2004Zhu et al, , 2008Qin et al, 2012;Medunić et al, 2021;Kang et al, 2022;Prevendar Crnić et al, 2022) or agricultural practices (Gao et al, 2007;Dhillon, 2014, 2016;Eiche et al, 2015Eiche et al, , 2019. Undoubtedly, the environmental implications of excessive Se and the associated threats to ecosystems and human health have been documented by a number of papers.…”

Selenium (Se) is an essential element for human health in trace amounts but is harmful in excess. Most plants contain a fairly low Se and crop Se supplements ensure adequate levels for human nutritional needs. Food is the primary source of Se for humans and due to differences in eating habits, its intake varies considerably. In the human body, selenium deficiency can lead to diseases of the endocrine, musculoskeletal, cardiovascular, reproductive, nervous and immune systems. Selenium is an important ingredient in glutathione peroxidase, the main cellular antioxidant enzyme, which can convert free radicals into peroxides, while vitamin E removes free radicals and neutralizes their potentially harmful effects. Excessive amounts of selenium in the human diet are considered toxic, causing liver and kidney damage, blood clotting, heart and liver necrosis, skin lesions, nausea, vomiting, and loss of hair and nails. Semiconducting properties of Se make it of special value for industry. Selenium is a rare element on the planet, and is a non-renewable resource due to its non-efficient and difficult recycling. Except of coal, which is commonly enriched in Se, there are no ores which could be mined for it. Herewith, the world's scarce Se resources need a careful management, monitoring, recycling, and stockpiling for future generations. The first part of this review outlines selenium concentrations in soil, water, and plants in terms of essential and toxicological effects on animals and humans, while the second part briefly overviews novel biotechnological methods of bioremediation of environmental selenium.

A part of the Raša Bay (western Croatia) is an estuary that is fed by the sediment load from the Raša River. The local area had been affected by the former Raša coal industry. The aim of this study was to determine levels of hazardous trace elements (HTEs) in bottom estuarine sediments, fish and mussels collected from two sites downstream of the Raša River mouth, and a wild boar’s kidney donated by hunters. The pseudo-total concentrations of 21 HTEs in sediments were obtained by the X-ray fluorescence (XRF) technique. The results showed that sediment collected closest to the former Raša coal separation unit Štalije was enriched in V, Sr, Ni, Cu, and Pb. Concentrations of HTEs in flathead grey mullet, wild blue mussels, and wild boar were obtained by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that Pb, Cd and Hg in fish and wild mussels were not elevated compared to the Regulation levels of contaminants in food. Lead and Cd in the kidney of a wild boar exceeded the prescribed maximum values for food. This study warrants further geochemical investigations of the Raša Bay environment.

Nowadays, trace metal contamination within urban atmospheres is a significant and concerning global issue. In the present study, two synanthropic bird species, namely, the feral pigeon (Columba livia f. domestica) and the rook (Corvus frugilegus), were employed as bioindicators to assess the atmospheric trace metal pollution in Iasi City, Romania. The concentrations of Ni, Pb, Cd, Co, Cr, and Cu were determined through high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF-AAS) of various tissues, including the liver, kidney, lung, heart, muscle, and bone, of feral pigeons and rooks collected in Iasi City. The order of trace metal concentrations in the tissues of feral pigeons and rooks in Iasi City was similar: Cu > Pb > Ni > Cd > Cr > Co. However, trace element values in most tissues were higher in the rook samples than in feral pigeon ones, except for Co, which had elevated levels in feral pigeon renal and cardiac tissues, and Cu, which registered the highest concentrations in feral pigeon liver and kidney tissues. While not statistically significant, Pb concentration values in the PM10 fraction of atmospheric particles positively correlated with Pb concentrations in rook kidney samples (p = 0.05). The concentration levels of Cd, Pb, and Ni in the PM10 fraction of air particles showed a positive correlation with Cd levels in the samples of pigeon heart and rook liver, kidney, and heart, Pb levels in the samples of pigeon kidney, heart, and muscle and rook liver and bone, and Ni levels in the samples of pigeon liver, kidney, and bone and rook liver, muscle, and bone, respectively.
