“…The highest concentrations of these heavy metals were mainly observed at Beylikduzu Coast, indicating the pollution level of this coastal region. In a study, sediment samples collected from the Bosphorus were reported to contain high levels of Cd and Pb compared to other investigated regions [41]. In the present study, after the Beylikduzu Coast, the second highest heavy metal contents were measured in the Bosphorus.…”

Heavy metal pollution in coastal regions has become a serious problem due to significant environmental degradations. In the present study, an algal species, U. lactuca, was investigated to assess the impact of heavy metal pollution on the six different locations along the coastal line of the Sea of Marmara in Istanbul. Heavy metal and mineral nutrient elements such as Ca, Cd, Cu, Fe, K, Mg, Mn, Pb, and Zn were determined using ICP-OES. The following lowest and highest concentrations (mg/kg; dw) were measured in Besides, metal deposition in the plant did not alter the mineral nutrient uptake pattern extensively, indicating relatively less contamination risk in the area. Overall, the comparison of heavy metal contents with seawater and sediment samples in the Ulva species showed that U. lactuca is a suitable plant for biomonitoring studies.

“…Thus S1 and S3 both have a large proportion of Cu associated with the reducible fraction (32 and 20% respectively). This distribution of Cu is unexpected as Cu is often reported to be associated with the oxidisable fraction (Span, 1984;Ramos et al, 1994;Azzawi et al, 1998;Algan et al, 2004).…”

The mobility of Cu, Pb and Zn in harbour sediments was investigated using single, sequential and kinetic extraction techniques. Each type of extraction provides different information on the mobility of these elements in the environment. The single HCl extraction assesses general mobility, the sequential extraction assesses geochemical partitioning and kinetic extraction allows quickly and slowly mobilized elements to be identified. Kinetic extraction also allows the influence of extraction duration to be assessed. The results presented in this paper highlight the complementary information provided by different types of mobility study.

“…In sediments these elements are associated with both the oxidisable fraction (Span, 1984;Ramos et al, 1994;Azzaoui et al, 1998;Pempkowiak et al, 1999;Baize and Tercé, 2002;Algan et al, 2004) and the reducible fraction (Rousseau et al, 2009;Leleyter et al, 2012;Hamdoun et al, 2015a). Generally Cd is not considered to be mobile in the sediment matrix (McLaughlin and Singh, 1999); however Baraud and Leleyter (2012) and Hamdoun et al (2015a) have found it to be associated with oxidisable and reducible fractions.…”

Ni is often presented as an element with a low mobility because it is bound with aluminosilicates (Span, 1984;Lopez-Sanchez et al, 1996;Algan et al, 2004). Pb has a generally high affinity for organic matter and carbonates (Town and Filella, 2002;Navarro et al, 2008).…”

The management of dredged marine sediment is an issue for many harbours, particularly when contaminant concentrations prevent disposal at sea. The stabilisation/solidification of the sediments with hydraulic binders for a use in road subgrade layer is a potential alternative solution. However, the environmental acceptability is not yet fully established. This paper presents the results of a case study to comprehensively determine the stabilisation of As, Cd, Cr, Cu, Ni, Pb and Zn. After demonstrating that stabilisation/solidification affects the microstructure of the sediment, a mobility study is realised (single, sequential and kinetic extractions). According to the regulatory/ technical guidelines the studied elements do not pose a risk to the environment. However, results from more complex mobility studies reveal that stabilisation in the short term is only effective for Ni while other elements are mobilised after treatment by at least one type of extraction. Stabilisation in the long term is not universally effective.
