“…Several studies have described how pollutants, especially trace metals, bind to finer grain-size particles. This facilitates transport and distribution of pollutants in marine sedimentary environments (Forstner and Wittman 1984;Horowitz 1991;Ligero et al 2001;Alyazichi et al 2015). However, the distribution of As and Mn do not conform to the bathymetric and grain-size gradients in the study area.…”

This study evaluated the distribution pattern and pollution of chromium, arsenic (As), manganese (Mn), nickel, lead, and copper in surface sediments along the northern Latium coast of the Tyrrhenian Sea in Italy. The enrichment factor, geoaccumulation index, and potential toxicity response index were used to evaluate the degree of contamination. These results show As and Mn contamination. The high enrichment and contamination levels of As and Mn are located in two hot spots. These elevations are due to naturally high levels of As and Mn in the Mignone River and the Marangone Stream as well as the intense human activity in the area including the largest energy production site in Europe (Torrevaldaliga Nord coal-fired power plant) and of one of the most important ports for cruise traffic in the Mediterranean Sea.

“…The highest percentages of mud accumulate in the inner and middle sites of the bays, such as Kogarah Bay, Oyster Bay, Oatley Bay and Woolooware Bay, because the wave and current activity is less compared with the main channel. Mud content is low in the main channel of the Woronora River, as well as around the edges and mouths of the bays, where local wind waves prevent deposition of fine particles or re-suspended them; these sites are dominated by sand (Alyazichi et al, 2015b). The percentage of mud declines as depth becomes shallower along the shoreline (Fig.3c).…”

Measurement of elevated trace elements is an important component of environmental assessment and management of estuarine marine sediments in systems adjacent to concentrated human activity. The present study surveys the estuarine sediments in selected tributary bays, creeks, and the upper segments of the Georges River system, NSW, Australia, which flows into the Tasman Sea through Botany Bay. A total of 146 surface sediment samples were analysed by X-ray fluorescence. Potential pollution of sediments was evaluated using potential load index, modified degree of contamination, and potential ecological risk index. The spatial distribution of trace elements varies between sites. Variable sources of contamination, including runoff from catchment areas, and emissions from watercraft and boatyards are contributing sources. Bay morphologies and their interactions with catchment and tidal flows play significant roles in the distribution of trace elements. The greatest concentration of trace elements occurs around discharge points and in the inner parts of bays that have high percentages of mud particles and organic matter. The lowest contamination by trace elements was found in sandy sediments along the shoreline and edges of the bays. Trace element distributions decline in concentration in residential-free areas and reach background levels in deeper sediment cores. The concentrations of trace elements were controlled by discharge points from the catchment area, marine boat activities, bay morphology, and sediment types (sand, silt, and clay). The highest pollutant concentrations are the result of past legal, but uncontrolled, discharge of waste from manufacturing into Salt Pan Creek. Creek.

“…The levels of metals in aquatic systems have drastically increased over the last few decades due to increased industrialization and urbanisation (Alyazichi, Jones, & McLean, ; Ghrefat, Abu‐Rukah, & Rosen, ; Gómez‐Parra, Forja, DelValls, Sáenz, & Riba, ; Yuan, Shen, Liu, Wang, & Meng, ). Water pollution with metals is a serious problem because they are toxic, many have a non‐biodegradable nature and can bio‐accumulate (Adhikari, Ghosh, Giri, & Ayyappan, ; Ghrefat et al, ; Schuurmann & Market, ).…”

Sediments act as a sink, being an integrator and an amplifier for metals in rivers, lakes and reservoirs. Thus, sediment quality has been recognized as an important indicator of aquatic pollution. The concentrations of aluminium (Al), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn) and sodium (Na) were studied in the surface sediments of Lake Chivero, Zimbabwe, to determine metal accumulation, distribution, pollution status and to distinguish natural background metal levels from human pollution sources. Sediment samples were collected from 17 locations during a two‐year (2014–2015) monitoring period during the hot–dry, hot–wet and cool–dry seasons. The overall mean metal concentrations exhibited the following decreasing order: Fe > Al>Mn > Ca>K > Mg>Na. The Mn levels for all sites and seasons were above the severe effect level (SEL). The highest metal and enrichment factor (EF) values were observed for the hot–wet season, indicating the period when the reservoir received the highest metal pollution from its catchment. The Geochemical index (Igeo) values for Mn for all seasons indicated moderately to strong contamination in sediments. The pollution load index (PLI) for all seasons indicated low pollution levels. Sediment contamination was attributed to natural sources for Al, Na and K and anthropogenic sources for Fe, Ca, Mg and Mn. The levels of studied metals in the Lake Chivero sediments are comparable to other eutrophic lentic systems. The results of the present study provide baseline information necessary for developing future metal pollution control strategies for Lake Chivero and its catchment.
