“…The multivariate statistic method was used to reveal the associations of the chemical elements. The factor analysis (FA) from an accurate number of variables provides smaller number of new variables, so-called factors that present the association of statistical significant variables (Davis 1986;Filzmoser et al 2005;Reimann et al 2002;Š ajn 2006;Yongming et al 2006;Ž ibret and Š ajn 2010).…”

The main aim of this article was to assess the atmospheric pollution with heavy metals due to copper mining Bučim near Radoviš, the Republic of Macedonia. The open pit and mine waste and flotation tailings are continually exposed to open air, which leads to winds carrying the fine particles into the atmosphere. Samples of attic dust were examined as historical archives of mine emissions, with the aim of elucidating the pathways of pollution. Dust was collected from the attics of 29 houses, built between 1920 and 1970. Nineteen elements (Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Li, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn) were analyzed by atomic emission spectrometry with inductively coupled plasma. The obtained values of the investigated elements in attic dust samples were statistically processed using nonparametric and parametric analysis. Factor analysis revealed three factors governing the source of individual chemical elements. Two of them grouping Ca, Li, Mg, Mn, and Sr (Factor 1) and Co, Cr, and Ni (Factor 2) can be characterized as geogenic. The third factor grouping As, Cu, and Pb is anthropogenic and mirrors dust fallout from mining operation and from flotation tailings. Maps of areal deposition were prepared for this group of elements, from which correlation of these anthropogenic born elements was confirmed.

“…As a first step, the frequency distribution of the data was examined through the frequency plots and EWMA control charts [24] of each element that can help to identify the type of distribution of the data and the outlier sites. To detect the relationships between the elements contents in moss and to determine the potentially influencing environmental factors partial component analysis (PCA) were used that explores the data onto hidden multivariate structures and explains their different means [25]. The most important PCs were determined and discussed.…”

“…The data set was log-transformed to ensure homogeneity of variance and overcome the consequence of different units (per-cent and ppm) (REIMANN et al, 2002). The log-normalized variables were tested whether or not have a normal distribution (REIMANN Table 2 Correlation coefficient matrix for mean size, carbonate, organic carbon, total nitrogen and trace metals in the Agios Kosmas surface sediments (n = 11).…”

Construction of the Olympic Games 2004Sailing Center is planned in the Saronikos Gulf, in the area of Agios Kosmas. A multi-disciplinary base-line study was carried out to provide background levels of inorganic and organic pollutants before the construction. Two shallow reefs (water depth 2-3 m) are the predominant features in the area's underwater topography. The reef consists of solid rock formations and pebbles, whereas sandy sediments cover predominantly the remaining seabed. Some pockets of fine-grained sand were identified within the existing marina. Sedimentary heavy metal contents were found to be low, showing only slight heavy metal enrichment, attributed mainly to heavy mineral abundance in the area. A small enrichment for lead could be related to anthropogenic sources. Patterns of low concentrations were observed for organic carbon and organic nitrogen. Conversely, the sediment petroleum hydrocarbon content was found to be relatively high, implying anthropogenic pollution related to ship effluents and increased marine traffic.
