“…The last of these locations, Orłowska tank situated close to the Oliwski Stream estuary, was characterized by extremely high Cu concentration reaching 1114 mg/kg d.w. (at the IN site). The Cu concentration at Orłowska IN was clearly higher than those reported in literature-in the range from 16 times more (sediments in open reservoir in Kielce, Poland [49] to 166 times more than sediments in retention pond in Puławy, Poland [17]. In the study conducted by Nowell et al [48] not only the mean HM concentrations for USA bottom sediments but also the highest values were reported.…”

Sediments of two urban streams in northern Poland outflowing to the Baltic Sea were assessed to explain the spatial variation in relation to urbanization level of the catchment, the role of retention tanks (RTs) and identification of pollution level. During the 3 month period of investigation sediment samples were collected from the inflow (IN) and outflow (OUT) of six RTs located on streams for flood protection. Six heavy metals (HMs) were investigated: Cu, Pb, Zn, Cd, Ni, Cr. The assessment of four geochemical enrichment indices used to quantify contamination of HMs in the sediments at IN and OUT samples was carried out. Contamination factor (CF), pollution load index (PLI), geoaccumulation index (Igeo) and potential ecological risk (RI) were calculated and the indices usefulness was assessed. Also, the hazard quotient (HQ) was calculated to assess health risk associated with dredging works. In sediments from RTs where paved surfaces constituted more than 70% of the catchment the HMs concentrations were from one to three times higher for Ni and from two to 143 times higher for Cu in comparison to soft catchment results. The extremely high Cu concentration (1114 mg/kg d.w.) found in sediments at RT Orłowska IN was most likely associated with large area of roofs covered with copper sheet. Calculation of CF, PLI, Igeo, RI, HQ indicators allows for a complex and multi-dimensional assessment of sediment status. Among these, CF and PLI classified the analyzed sediments as most polluted. Basing on the sedimentary HMs concentrations the health risk level via dermal exposure pathway was assessed as low.

“…The enrichment factor (EF) helps to establish the source of HMs: natural or anthropogenic, normalizing the HM concentration with a reference element such as aluminium (Al). 11,19,21,41 For the normalization, the Al concentration measured in each sample and Al B n concentration in soils reported by Rauch and Pacyna 40 were used.…”

“…The EF for each trace metal could be categorized into five levels of pollution. EF < 2 represents zero or minimal enrichment, suggestive of zero or minimal pollution; 2 ≤ EF < 5 indicates moderate pollution; 5 ≤ EF < 20 indicates significant pollution; 20 ≤ EF < 40 indicates strong pollution; and EF ≥ 40 indicates extreme pollution [23].…”

One important category of traditional remedies is medicinal plants, which are widely consumed by the population and often subjected to contamination. For the first time, the elemental composition of five wild medicinal plants traditionally consumed in the Republic North Ossetia—brook-mint (Mentha longifolia), oregano (Origanum vulgare), St. John’s wort (Hypеricum perforаtum), thyme (Thymus daghestanicus), and fireweed (Chamaenerion angustifolium)—and corresponding soil samples was determined. This investigation aimed to assess the degree of toxic element accumulation in plants and the possible toxic effect of the analyzed plants on human health. The analysis encompassed the quantification of 36 major and minor elements in soil samples, alongside the detection of 23 elements in plant samples using instrumental neutron activation analysis. According to contamination and enrichment factors, which were calculated in order to assess the level of soil pollution, elements such as As, Sb, Zn, and U in soil may originate from both geogenic and anthropogenic sources. In all plant samples, the most abundant major elements were K and Ca and their content ranged from 9870 to 49,500 mg·kg−1 and 5400 to 20,000 mg·kg−1, respectively, while among the microelements, Fe (54–2080 mg·kg−1) and Mn (27.8–190 mg·kg−1) can be highlighted as the most abundant. The transfer factor was calculated to estimate metal uptake from soil in plants. The highest values of the transfer factor were obtained for Mo, K, Ca, and Zn. The daily intake of metals and the health risk index were calculated to assess the safety of the collected plants. The health risk index was below the threshold for all plants suggesting a probable non-carcinogenic effect. Principal component analysis and linear discriminant analysis were used as classification techniques. The principal component analysis allowed us to define the main groups of elements and associate them with their sources of origin, while discriminant analysis enabled us to discriminate plant samples by species.
