“…16 The lower part of the core, Unit 1, is between 549-183 cm below sediment surface (bss), and is characterised by consolidated sediments with a dominantly brownish colour. Based on colour and consistency of the sediments, the sediment core was divided into two units.…”

“…Bergen, which was founded in the 11 th century, has grown to a city of more than 260 000 inhabitants today, with the main increase occurring in the 20 th century. 15 An extended historic review can be found in Andersson et al 16 LL has for centuries been a sink for domestic sewage and waste. The precipitation is highest in the last four months of the year and lowest from April to June.…”

The 7000 years transition from a pristine environment towards a modern city has brought a number of chemical changes and effects to urban lake sediments in Bergen. Metals, such as Pb, Hg, Zn, Cu and Fe, display a large anthropogenic influence and reflect historical point sources that existed within the drainage area from approximately AD 1790 until today. The concentration peaks alternate with intervals of lower concentration due to phases of coarser grained sediment input but also periods of potentially reduced metal influx. All discussed elements, except Cd, increase in concentration with decreasing grain size and also correlate with the amount of clay fraction particles. The results emphasize the importance of considering grain size when interpreting sediment chemistry. Correlation with TOC is not apparent in the same extent. The transition from natural to anthropogenically influenced sediments, which is characterised by a sudden increase of several elements, is accompanied by a reduction in Cd, As and Ni concentration. This is interpreted to be the result of hypoxia, changes in pH and reduced erosional input. Factor analysis and the comparison with reference sediments indicate that the elements Pb, Hg, Zn and Cu most clearly demonstrate man-made pollution. Analyses of stormwater culvert sediments suggest that urban runoff contributes to the pollution load today, with standing building mass and traffic contributing to the load.

“…A recent increase on concentrations of PAHs in the environment may be associated to economic development and population increase, which leads to a greater number of sources of these compounds (ANDERSON et al, 2014;YANG et al, 2016). The majority of the anthropogenic sources are related to exploration, transformation and combustion of fossil fuels (WITT, 1995).…”

Polycyclic aromatic hydrocarbons (PAHs) are considered persistent organic pollutants and can cause serious damage in some organisms, including mutagenic and carcinogenic properties. The aim of this study was to evaluate the PAH concentrations in an urban basin and use diagnostic ratios to possible distinguish sources of contamination. The surface water analysis showed predominance of compounds containing 3 to 4 aromatic rings while in suspended particulate matter and sediment there was a predominance of compounds containing 4, 5 and 6 rings. Although present in low concentrations in the sediment, assessment of toxicity equivalent factor (TEF) showed values higher than 3 ng g -1 pellet to 50% of the samples with values of up to 125.35 ng g -1. The use of diagnostic ratios allowed verifying that the main source of PAHs in these aquatic environments, are pyrogenic sources. Still, the use of such relations should be done with caution, trying to assess possible interference of degradation factors Keywords: Diagnostic ratios; Risk assessment; Polycyclic aromatic hydrocarbons; Environmental contamination. RESUMOHidrocarbonetos policíclicos aromáticos (HPAs) são poluentes orgânicos considerados persistentes e que podem causar sérios danos em alguns organismos, incluindo propriedades mutagênicas e carcinogênicas. O objetivo desse estudo foi avaliar as concentrações de HPAs em uma bacia urbanizada e utilizar relações diagnósticas para tentar distinguir fontes de contaminação. A análise de água superficial mostrou um predomínio de compostos de 3 a 4 anéis aromáticos, enquanto que para material particulado suspenso e sedimentos houve uma predominância de compostos com 4, 5 e 6 anéis aromáticos. Apesar de baixas concentrações no sedimento, avaliação de equivalentes de toxicidade mostraram valores superiores a 3 ng g -1 de sedimento para 50% das amostras, com valores de até 125.35 ng g PAHs diagnostic ratios for the distinction of petrogenic and pirogenic sources: applicability in the Upper Iguassu Watershed -Parana, Brazil
