Artisanal and small gold mining activity in Wonogiri Regency has long been done with problems on environmental quality. This study was aimed to analyze the levels and spatial distribution of heavy metals in the mining area. Survey of  mining and amalgamation sites, sampling the soil and tailings had been conducted. There were 66 samples of soil and tailing were collected, analysis of heavy Fe, Mn, Pb, Hg, As and Co, using X-ray fluorescence (XRF). Normal distribution test of data was conducted using the Kolmogorov-Smirnov and Shapiro Wilk.  The spatial distribution of heavy metals was described using Krigging method. Contents of most heavy metals in the area studied were high, except for Co. According to the distribution pattern of heavy metals indicated that the contamination caused by the mining.

Abstract Vary heavy metals scattered in suspension loads and re-sedimentation from the tailing of the offshore-alluvial tin mining at Tanah Merah and its surroundings, Central Bangka Regency. Research is needed to determine the type, composition, spatial distribution of heavy metals, and potential pollution. The active surface-sediments were taken from shallow marine systematically around the offshore tin mining area in the east season. Geochemical analysis of sediment using x-ray fluorescence, coupled with minerals and sieve analysis, and support by spatial analysis. These sediments have dominant the sand-size (range very-fine sand to coarse sand) and silt, contained predominantly large quantities of quartz minerals and shell fragments of marine animals. The metals are in the following decreasing order: Cr>Zn>Pb>Ni>Cu>As>Co>Cd. The spatial distribution of heavy metals generally has a relatively south, east, and north position, with concentrations occurring along the coastline and showing the degradation composition towards the open sea. The marine sediments are uncontaminated to moderately contaminated by Cd and Pb, indicate both natural and anthropogenic enrichment, low the pollution load index (PLI), and have various potential ecological risks index (RI) (low to very high RI).

Metals distribution (Cu, Zn, Pb, Mn and Ni) in campus wastewater was examined by nonparametric tests (Kolmogorov-Smirnov (K S) and Friedman One-Way ANOVA). Based on the K-S test, all metals except zinc followed normal distribution. Based on the Friedman One-Way ANOVA test, nickel concentration posed substantial difference between three sampling stations under study (p < 0.05). All metals posed under the critical values on the basis of Environmental Quality (Sewage and Industrial Effluents) Regulations (1979). The water parameters (BOD, COD, TSS, pH and temperature) were also implicated to inform the chemical background of wastewater under study in relation to metals distribution.

Tinovul Mare Poiana Stampei is situated in the northern group of the Oriental Carpathians within the Dornelor Depression, one of the richest peat areas in Romania. In this study we have performed analyses of certain heavy metals (Cr, Co, Ni, Cu, Zn, Pb, As and Cd) found in the forest soils adjacent to the Tinovul Mare Poiana Stampei peat bog. The analyses performed through X-ray fluorescence spectrometry indicated the following variation limits (mg/kg): Cr: 20-66; Co: 8-29; Ni: 16-78; Cu: 16-42; Zn: 36-199; Pb: 21-229; As: 5.5-36 and Cd: 0.01-1.4. The outcomes of the present study indicate high concentrations for certain (Ni, Pb and As). These concentrations exceed the alert threshold established by the Romanian Law, according to Order no. 756 of November, 3rd 1997.

Concentrations and spatial distribution of heavy metals on the left and right banks of the river Nemunas bottom sediments are analyzed in this article. The research methodology of X-ray fluorescence spectrometry for bottom sediments and operating principles of XL2 spectrometer used for analysis are overviewed. The results of analysis are presented and compared with LAND 20-2005 requirements as well as studies that were carried out previously. The influence of Alytus city for Nemunas river sediments quality is assessed. Dischargers formed additional samples which were taken and included to the list of ordinary samples. The trend of heavy metals (Cd, Cu, Cr) concentrations showed the growth of pollution downstream the urban area. The estimated Zd (total pollution) values clearly indicated higher contamination by heavy metals on the left bank of Nemunas River. Extensive surveys of river sediments allow assessing the extent of anthropogenic impact, which can be harmful to the river ecosystem and human health.

Abstract This paper presents aspects related to water pollution with heavy metals from the Tarnita mining area before and after the cessation of the mining activity. The impact of heavy metals on waters is important because these metals have a negative impact on both human health and aquatic ecosystems. All research data showed that, even the mining activities from this area were suspended, the sterile still pollutes the soil and water
