“…Only Mg had a slightly higher enrichment factor (EF = 1.35). Macroelements are typically accumulated only periodically in the SML, e.g., in the period of spring phytoplankton and phytoneuston growth, Mg may have been taken up to form chlorophyll a [9]. In urban water bodies, the accumulation of trace metals in the SML may largely be the result of atmospheric deposition compared to in the case of water bodies located at a distance from urban areas.…”

“…Another macroelement, Na, showed a positive correlation with phytoplankton. Analyses were conducted in the spring period; the response of phytoplankton to Na may be connected with the leaching of this nutrient from the urban catchment in which together with the surface runoff Na, originating from salt used for the roads and urban street de-icing, may penetrate urban water bodies [9,97]. With surface runoff, sulfur compounds, while being nutrients, may penetrate water bodies, although they are harmful at excessively high concentrations.…”

“…At the same time, it is the zone that accumulates nutrients [5,8]. In turn, such substances as calcium, magnesium, potassium or sodium, being macroelements found at high concentrations in the pelagic zone, are usually not accumulated in the SML [9]. The SML is inhabited by neustonic autotrophic and heterotrophic microorganisms, which exhibit both enzymatic and high respiratory activity [5,[10][11][12].…”

The concentration of chemical and biological parameters in the ecotone of the surface microlayer (SML) occurring between the hydrosphere and the atmosphere of urban water bodies was investigated. Parallel, sub-surface water (SUB) analyses were carried out to compare the SML properties with the water column. The concentrations of trace metals, macronutrients, nutrients, chlorophyll a, pheophytin, abundance and biomass of phytoplankton and the number of heterotrophic bacteria in both studied layers were analyzed. Each of the studied groups of chemical parameters was characterized by specific properties of accumulation. Trace metals occurring in concentrations below 1 ppm, such as Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Zn and metalloid As, were accumulated to a higher degree in SML than in SUB. Macroelement concentrations, with the exception of Mg, were lower in the SML compared to the SUB. Nutrients, autotrophic and heterotrophic microorganisms occurred in the SML to a higher degree than in the SUB. Bacillariophyceae dominated the analyzed water bodies, which are typical for the spring period, as well as Chrysophyceae, Chlorophyceae, Dinophyceae and Euglenophyceae. Cyanobacteria dominated in one of the ponds. The abundance of individual phytoplankton groups was significantly correlated with Ca, K, Na, P-org, SO42−, F−, Al and Sr.

Abstract. In areas of urban infrastructure, ponds play an important role. They are places of rest and recreation, and they facilitate contact between city dwellers and the aquatic environment. They are also a place for living waterflow and ichthyofauna. Urban ponds are susceptible to anthropogenic influences, and their self-cleaning capacity is limited due to their small size. The city of Słupsk is located in northern Poland. Coal combustion in domestic boilers and transport cause dust emissions to be released into the atmosphere. The concentration of particulate matter and heavy metals in PM10 in Słupsk is much higher than in neighbouring village Gać. This affects metals deposition from the atmosphere. Two urban ponds in Słupsk were the object of the research. Sampling station No. 1 was located in the southern part of the Raj Pond situated deep into the forest area, a considerable distance from urban buildings. Sampling station No. 2 was located at the Juniorów Pond located near the city centre. Water samples were taken from a depth of 10 cm. To investigate the deposition from the atmosphere, atmospheric precipitation was collected in a collector located in the city of Słupsk. The concentrations of Li, Al, Cr, Mn, Fe, Ni, Se, As, V, Sr, Cd and Pb were analyzed in the obtained water samples. Measurements were made using an ICP-MS mass spectrometer. From the obtained results, it was observed that the concentrations of Li, Al, Cr, Mn, Fe, Se, Sr and Cd were higher at station No. 2 located near the city centre.

“…Their contents were relatively homogeneous as reflected by generally low values of SD calculated for each element. Generally, the concentrations of majority of studied elements largely exceeded those observed in surface waters, including environments under high human pressure (Rzymski et al 2014 ; Jitar et al 2015 ; Strungaru et al 2015 ; Antonowicz et al 2016 ; Plavan et al 2017 ).…”

Copper mining generates large quantities of waste, tailings, and acid outflows causing long-term environmental impacts and potential threats to human health. Valea Şesei is the largest tailing impoundment in Romania, created by flooding the valley (known as Valea Şesei) of the Metalliferous Mountains (a division of the Apuseni Mountains) with copper mining waste. The present study (i) estimated the total volume of tailings in this area; (ii) screened the concentration of 65 elements (rare earth and platinum group elements, alkali metals and alkali earth metals, transition and post-transition metals and metalloids) and cyanide concentrations in wastewater samples collected from tailing impoundment; (iii) evaluated the toxicity of these water samples using five in vitro bioassays employing human cells isolated from healthy donors and a short-term (1 h) exposure model. The sampled waters were highly acidic (pH 2.1–4.9) and had high electrical conductivity (280–1561 mS cm−1). No cyanides were detected in any sample. Water samples collected from the stream (AMD) inflowing to the tailing impoundment were characterized by the greatest concentrations of alkali metals, alkaline earth metals, transition and post-transition metals, metalloids, rare earth elements, and noble metal group. At other sites, the elemental concentrations were lower but remained high enough to pose a relevant risk. The greatest magnitude of in vitro toxic effects was induced by AMD. Observed alterations included redox imbalance in human neutrophils followed by lipid peroxidation and decreased cell survival, significant aggregation of red blood cells, and increased prothrombin time. The study highlights that Valea Şesei is a large sink for toxic elements, posing environmental and health risks, and requiring action to prevent further release of chemicals and to initiate restoration of the area.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-017-9782-y) contains supplementary material, which is available to authorized users.
