“…According to literature, the occurrence of metals such as Cd, Cr, Ni and Zn is not a surprise. The literature suggests a strong correlation between these metals and urban areas (GOMES et al, 2009;MINELLA, 2009;RIVARO et al, 2011;MCKEE;GILBREATH, 2015).…”

“…Chemical elements (metals and semi-metals) such as As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn have been considered as a fingerprint to trace pollution in urban areas (GOMES et al, 2009;MINELLA, 2009;RIVARO et al, 2011;MCKEE;GILBREATH, 2015). Despite the discussion about iron, some authors also include this metal as tracer of pollution (POLETO; MERTEN; MINELLA, 2009;MCKEE;GILBREATH, 2015;SILVA;SIQUEIRA;LEANDRO, 2015), even been one of the most abundant on Earth as well Al, Ca, K, Mg, Si and Ti.…”

The suspended sediments are a special compartment that characterizes the effects of land use in the watershed. Such compartment is able to trap organic compounds as well as metals in general. Spatial variation of concentrations can be accounted for the land use, soil composition and pollution. In this work, we aimed to assess the spatial variation of metals and phosphorus concentration presented in suspended sediments collected in a river under urban occupation. Using time-integrated suspended sediment samplers, samples were collectec in three sites covering different levels of occupation: Almirante Tamandaré (P1) and two in Curitiba city (Tingui Park -P2 and Barigui Park -P3). The sampler was settled to be 20 cm below the water surface and it was removed after 30 days. Twelve samples were collected to examining the following elements Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, La, Mg, Mn, Na, Nb, Ni, P, Pb, Sc, Sn, Sr, Th, Ti, V, Y, Zn and Zr by ICP-OES. The first site is characterized with only 5.73% of urban area; meanwhile the site P3 has the highest urban area 54.06%. Among the twenty seven elements, nineteen showed a positive variation in concentration between collected sites, giving indication that an enrichment of metals along the river. The following elements showed positive variation: P (151.20%), La (117.98%), Cd (93.33%), Cr (71.43%), Na (68.75%), Ni (68.07%), Y (66.67%), Th (63.64%) and Zn (56.77%). Considering local reference values it is concluded that Cd, Cr, Ni, P, Y and Zn appear associated with urbanization increase in the basin; Co, Sc, Sn, Cu and Mn appear possibly associated with urbanization; Ba, La, Na, Pb and Sr show inconclusive behavior in relation with urban influence ; Al, Fe, Nb, Th, Ti, As, Ca, K, Mg, Zr and Va demonstrate not be associated with urbanization.Keywords: Suspended sediments; Metals; Urban river. RESUMOOs sedimentos em suspensão formam compartimento ambiental especial que caracteriza os efeitos do uso do solo na bacia hidrográfica. Tal compartimento é capaz de armazenar compostos orgânicos e metais em geral, cujas variações espaciais nas concentrações podem ser associadas ao uso do solo, à composição do solo e à existência de fontes poluidoras na bacia. Aqui avaliamos a variação espacial da concentração de metais e fósforo nos sedimentos em suspensão em rio sob influência urbana. Por meio de amostradores integrados no tempo, amostras foram coletadas em três pontos com diferentes níveis de ocupação urbana: com 5,73%, 22,30% e com 54,06% de urbanização. Cada amostrador foi instalado de modo a ficar 20 cm abaixo da superfície da água, sendo coletadas amostras a cada 30 dias em cada ponto amostral. Doze amostras foram obtidas para análise de 27 elementos químicos. Dos 27 elementos selecionados para análise, 19 apresentaram taxas de variação de concentração positivas, indicando enriquecimento ao longo do trecho de rio amostrado. As maiores taxas de variação positivas foram obtidas para P (151,20%), La (117,98%), Cd (93,33%), Cr (71,43%), Na (68,75%), Ni (68,07%), Y (66,6...

“…Although the studies of element contents in the Adriatic sediments date back more than 30 years, the available data and publications are mostly limited to selected coastal areas of the eastern Adriatic [5] and some data sets of major, minor and trace elements covering the southeastern Adriatic [6]. Investigations of the surface sediment in the southeastern Adriatic have intensified in the Albanian coastal area [4,7,8] and some hint of the work in relation to the concentrations of the elements in surface sediments in the Montenegrin coast [9,10].…”

is on the UNESCO's World Heritage List. There are no published papers related to the surface sediment pollution of the Bay. For the first time, elements were measured in surface sediments at nine locations in the Bay by the energy dispersive X-ray fluorescence spectrometry (ED-XRF) technique. Si, Fe, Ca, K, Ti, Mn, P, Ba, Cr, Sr, Zn, Rb, Ni, Cu, Pb, As, Sn, Sb, Hg and Cd were quantified in the surface sediments. Sediments were classified as non-polluted or polluted by counting the enrichment factor (EF), metal loading index (MLI) and geo-accumulation index (I geo ) based on the elemental background level of the analyzed elements in the literature, or by the Sediment Quality Guidelines (SQGs) of USEPA (United States Environmental Protection Agency). Based on USEPA's SQGs, the surface sediment in the entire Bay can be classified as heavily polluted by As and Cr, and non-polluted by Cd and Hg, and, related to the sites, the surface sediment at the Tivat-Arsenal site was heavily polluted and at the Orahovac site was not polluted at all. The PLI (pollution load index) values for the locations of Tivat-Arsenal and Orahovac are in agreement with the conclusion based on USEPA's SQGs. The results in this paper will establish an initial view of sediment pollution and the state of the Bay's environment.Keywords: multi-element analysis; marine sediment; pollution index; geochemical analysis АНАЛИЗА НА МАКРО-И МИКРОЕЛЕМЕНТИ ВО ПОВРШИНСКИТЕ СЕДИМЕНТИ СО РЕНДГЕНСКА ФЛУОРЕСЦЕНТНА СПЕКТРОМЕТРИЈА ЗА УТВРДУВАЊЕ НА МОЖНАТА ЗАГАДЕНОСТ НА ЗАЛИВОТ БОКА КОТОРСКА, ЦРНА ГОРАЗаливот Бока Которска е на листата на светското наследство на УНЕСКО. Не постојат објавени трудови поврзани со површинското загадување на заливот. За прв пат на девет локации во заливот елементите во површинските седименти се измерени со техниката на енергетска дисперзиона рендгенска флуоресцентна спектрометрија. Во површинските наслаги беа измерени Si, Fe, Ca, K, Ti, Mn, P, Ba, Cr, Sr, Zn, Rb, Ni, Cu, Pb, As, Sn, Sb, Hg и Cd. Наслагите беа класифицирани како незагадени или загадени со пресметување на факторот на збогатување на наслагите (седиментите) со метали (EF), индексот на таложење на метали (MLI) и гео-акумулационен индекс (I geo ) базиран на литературните податоци за елементарно ниво на анали-зираните елементи, односно врз основа на Упатството за квалитетот на седиментот (SQG) на USEPA. Врз основа на SQGs на USEPA, површинскиот седимент во заливот како целина може да се класифицира како силно загаден со As и Cr и како незагаден со Cd и Hg, а во однос на одделни локации површинскиот седимент во Тиват-Арсенал беше многу загаден, а во Ораховац воопшто не беше загаден. Вредностите PLI за локациите Тиват-Арсенал и Ораховац се во согласност со
