“…Hg halides, Hg bound to humic acids or MeHg), while stable and insoluble forms (i.e. HgS or matrix-bound Hg) accounted for less than 30% (Gębka et al 2020 ). Similar results were obtained in contaminated soil from southern Poland, where about 35% of soil Hg was in stable form (Pogrzeba et al 2016 ).…”

“…In small watercourses in northern Poland, the THg concentration was similar to the Vistula and ranged from 4.1 to 6.7 ng L −1 (Gębka et al 2018 ). The highest THg concentration in rivers occurred during thaws, which released pollutants that had been accumulating over the winter (Gębka et al 2020 ). Downpours and floods had a crucial impact on a THg load carried by rivers (Saniewska et al 2014c ; Jędruch et al 2017 ) (Table S1 b).…”

The goal of this paper is to assess the current status and trends of total mercury (THg) contamination of the atmosphere and terrestrial ecosystems in Poland. The study shows that the reduced domestic and worldwide atmospheric emission of Hg resulted in decreased THg level in the terrestrial biotope and biosphere. Considering that Poland is one of the main Hg emitters in Europe, the THg concentrations in its abiotic environment are still elevated. However, the THg level in terrestrial organisms is relatively low, which is because a large proportion of Hg deposited on land is accumulated in organic-rich soils. Regarding the THg concentration, consumption of wildlife and livestock from Poland is safe for humans. Nevertheless, the authors indicate the need for effective environmental monitoring, based on selected bioindicators, which is crucial considering the slowing reduction of Hg emission combined with the consequences of the changing climate.

“…• Fertilizers and insecticides on cultivated land may leak to the soil and sea, thus, it can be expected that change of land 1270 use has a considerable impact on emissions of contaminants (+) to the coastal sea. In addition, remobilization of toxic mercury from the soil (where it has been accumulated for decades) and transport to rivers and into the sea has been shown (Saniewska et al, 2014;Saniewska et al, 2019;Gębka et al, 2020).…”

Abstract. Coastal environments, in particular heavily populated semi-enclosed marginal seas and coasts like the Baltic Sea region, are stongly affected by human activities. A multitude of human impacts, including climate change, affects the different compartments of the environment, and these effects interact with each other. As part of the Baltic Earth Assessment Reports (BEAR), we present an inventory and discussion of different human-induced factors and processes affecting the environment of the Baltic Sea region, and their interrelations. Some are naturally occurring and modified by human activities (i.e. climate change, coastal processes, hypoxia, acidification, submarine groundwater discharges, marine ecosystems, non-indigenous species, land use and land cover), some are completely human-induced (i.e. agriculture, aquaculture, fisheries, river regulations, offshore wind farms, shipping, chemical contamination, dumped warfare agents, marine litter and microplastics, tourism, coastal management), and they are all interrelated to different degrees. We present a general description and analysis of the state of knowledge on these interrelations. Our main insight is that climate change has an overarching, integrating impact on all of the other factors and can be interpreted as a background effect, which has different implications for the other factors. Impacts on the environment and the human sphere can be roughly allocated to anthropogenic drivers such as food production, energy production, transport, industry and economy. We conclude that a sound management and regulation of human activities must be implemented in order to use and keep the environments and ecosystems of the Baltic Sea region sustainably in a good shape. This must balance the human needs, which exert tremendous pressures on the systems, as humans are the overwhelming driving force for almost all changes we see. The findings from this inventory of available information and analysis of the different factors and their interactions in the Baltic Sea region can largely be transferred to other comparable marginal and coastal seas in the world.

“…One reason is the continued deposition of mercury on land, where the metal accumulates in the surface layer of soils [8][9][10][11]. Studies conducted by scientists indicate that elevated concentrations of the metal are found near individual household furnaces as well as in larger urban areas where mercury is emitted into the environment during energy and heat production [12][13][14][15][16]. This indicates a significant impact of coal burning on environmental mercury concentrations.…”

“…This indicates a significant impact of coal burning on environmental mercury concentrations. Moreover, despite the introduction of legal restrictions that have led to a reduction in anthropogenic sources of mercury, the metal that has been deposited over decades is now being remobilised from land into river water [13,16,17,18]. The process of Hg leaching into rivers is stimulated by surface runoff, which in turn is amplified by heavy rains.…”

Mercury (Hg) is recognised as a global environmental pollutant. Despite numerous studies being conducted around the world, the transformation of mercury in natural environments is still not fully understood. In addition, increasing droughts and heavy rains are currently observed to contribute to changes in the circulation of Hg. The purpose of this study was to recognise the influence of extreme meteorological and hydrological conditions on the inflow of various forms of mercury to the coastal zone of the Bay of Puck. The studies were carried out at estuarial stations of four rivers belonging to the southern Baltic Sea catchment: Reda, Zagorska Struga, Gizdepka and Płutnica. The results showed that meteorological and hydrological parameters affect mercury speciation in river catchments, which translates into inflow of labile mercury to the southern Baltic Sea.
