Study of trace metals during estuarine mixing of Jarahi River water with the Musa Estuary water
Flocculation of metals is one of the most important estuarine processes that occur due to the mixing of seawater and river water and colloidal metals undergo this process come in the form of flocculants. Due to the important role of flocculation process in producing suitable food sources for aquatic organisms and reducing the amount of input pollution into aquatic environments, the present stud...
متن کاملDistribution of Heavy Metals in the Environmental Samples of the Saemangeum Coastal Area, Korea
In order to understand the distribution of elements in the environmental samples, surface seawater and sediment samples collected from the Saemangeum region of western coast of Korea were analyzed for their concentrations of major and trace elements. Dissolved heavy metal concentrations except for Cd were highest in inner part of the Saemangeum dike and in the Geum River Estuary. Riverine disch...
متن کاملThe Distribution of Trace Metal Pollutants within Intertidal Sediments of the Tamar Estuary, Sw England
Concentrations of trace metal pollutants are frequently reported from intertidal sediments (e.g. Bryan and Langston, 1992; French, 1993; Lindsay and Bell, 1997; Pirrie et al., 1997, 2000) and as these areas are often sites of intense human and animal activity, the level of contaminants are of particular interest with respect to environmental health (Rae, 1997; Clark, 1997). When trace metals ar...
متن کاملAnthropogenicimpacts on heavy metals (Pb, Ni, Zn and Fe) concentration in surface sediments of Shoor River Estuary, Bandar Abbas
Toxicity of trace metals in the environment, bioaccumulation in aquatic environments and in food chains are of great importance.This study concentrates on the distribution patterns of some heavy metals (Pb, Ni, Zn and Fe) in surface sediments of Shoor River estuary to obtain an overall classification for the origins of the metals in the studied area. In order to determine the degree of Contamin...
متن کاملDistribution of particulate , colloidal , and dissolved mercury in San Francisco Bay estuary . 1 . Total mercury
Surface water samples were collected from the San Francisco Bay estuary in September–October 2000 (low flow) and March 2001 (high flow). Total mercury (Hg) concentrations were measured in unfiltered, filter-passing (,0.45 mm), colloidal (1 kDa–0.45 mm), and dissolved (,1 kDa) fractions. Particulate Hg was the dominant phase (88 6 7%, n 5 29) in unfiltered water. Suspended particulate matter (SP...
