Distribuição de metais pesados em sedimentos do sistema estuarino da Ilha de Vitória-ES

Abstract: DISTRIBUTION AND ABUNDANCE OF HEAVY METALS IN SEDIMENTS FROM VITÓRIA ISLAND ESTUARINESYSTEM. Heavy-metal concentration in sediment is an important parameter for identifying pollution sources and assessing pollution levels in aquatic ecosystems. In this context, the present study aimed at determining concentrations of heavy metals in sediments from the Vitória estuarine system, Brazil. Twenty nine stations were surveyed to assess the spatial distribution of heavy metals. The metals for silt-clay fractions (<63 … Show more

“…According to Jesus et al (2004), recovery factors between 75 and 110% are considered satisfactory (Table 4). Only chrome was reported to be 66.7% recovery, Edila Maria Kickhöfel Ferrer et al possibly because it is a pseudo-total digestion and the reference value is relative to the total digestion of that reference material.…”

“…Sites P2 and P3 showed large variability of metals from sediment and water samples, respectively, as well as Jesus et al (2004) and Miranda et al (2009). Metals concentrations in water tend to be lower and can oscillate drastically (Saraiva et al, 2009), depending on the water flow or intermittent discharge of effluents.…”

“…These metals are often in industrial, urban and agricultural effluents (Lopes, 2006). The environmental impact caused by metals is one of the biggest environmental concerns of today, especially when there is interaction with human populations (Jesus et al, 2004).…”

“…Entretanto, com o advento da industrialização e urbanização, o homem vem elevando as concentrações destes metais a níveis maiores do que os naturais, ocasionando a contaminação dos ecossistemas aquáticos e terrestres 2 e se tornando um dos maiores problemas ambientais da atualidade. 2 Vários organismos podem se utilizados como biomonitores ou bioindicadores de contaminação ambiental por possuírem respostas particulares aos vários poluentes, sendo então empregados para detectar qualitativa e quantitativamente a atual situação de estresse do local onde ocorrem 3 . Fatores como hábito alimentar, tamanho e idade dos organismos, podem afetar as concentrações dos metais nesses animais, podendo variar de espécie para espécie, de região para região, assim como nas diferentes épocas do ano.…”
