Estuarine environment is complex and receives different contaminants from numerous
sources that are persistent, bioaccumulative and toxic. The distribution, source …

A suite of 36 surface sediment samples, taken between 10 and 100m water depth in
Mejillones Bay (Northern Chile), were analyzed for mineralogy, grain size, total organic …

Heavy metals, such as arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb),
mercury (Hg) and zinc (Zn), are major environmental problem due to their toxic nature …

Three sediment cores were sampled at Sepetiba Bay and four cores at Ribeira Bay, Rio de
Janeiro State, Brazil. Sediment accumulation rates and chronologies were obtained from …

Acid drainage influence on the water and sediment quality was investigated in a coal mining
area (southern Brazil). Mine drainage showed pH between 3.2 and 4.6 and elevated …

Abstract Heavy metals concentrations (Fe, Cu, Zn, Ni, Cr, Co, Pb, and Cd) were scrutinized
during two monitoring years (2001 and 2011) in the coastal sediment of Pakistan. The status …

Human occupation of coastal areas promotes the establishment of non-native species but
information on bioinvasions is usually biased toward the Northern Hemisphere. We …

Abstract Concentrations of 12 metals (Fe, Mn, Cr, Mo, Ni, Pb, Se, Sr, U, V, Zn, and Zr) in
surface sediments of Karachi Coast, Pakistan were determined to evaluate their distribution …

The use of fish species uses as bioindicators is an important environmental monitoring tool.
Histological biomarkers are adopted to assess the health conditions of different organisms …

This work aims to propose new standards to assess the degree of sediment contamination in
saline and brackish environments, since the legislation currently used in Brazil is based on …
