“…Thus, several signs of severe trace metal pollution (especially of Cu, Ni, Cr, and Zn) in intertidal sediments off Panweol undoubtedly originate from industrial sources (Ahn et al 1995). Similar trace metals pollution (especially Zn, Cd and Pb) was also reported in surface sediments of Jinhae Bay of the South Sea that receives metal-contaminated wastewater (see Table 3; Kwon et al 2001). Intertidal sediments of this study are significantly lower in most trace metals compared with off-shore sediments near industrialized cities such as Panweol and Jinhae (see Table 3).…”

Purpose A number of publications have raised trace metal contamination of soils and sediments within and around shooting ranges used for sport or military training. To our knowledge, however, there is no publication on the contamination of sediments derived from military shooting ranges in a marine environment. Therefore, this work was purposed to assess the dispersion and fractionation of ammunition-and bomb-derived trace metals in intertidal sediment. Materials and methods Intertidal sediments (n=32) were collected around a small island that has been used as a target for military air weapons shooting training for more than 50 years in the west coast area of South Korea and were analyzed for size distribution, pH, organic/inorganic carbon contents, and trace metals concentrations. Three kinds of the chemical extraction were used for trace metals analysis: 1) total extraction with a 4:4:1 mixture of HF-HNO 3 -HClO 4 acid, 2) partial extraction with 0.1 N HCl, and 3) sequential extraction by a modified Community Bureau of Reference (BCR) method. We also compared our total concentration data with values reported for shallow marine sediments off South Korea and worldwide. Principal component analysis (PCA) was also used to identify shooting-related anthropogenic inputs for some trace metals. Results and discussion Ranges of total trace metals concentrations (mg kg −1 ) are: Cd, 0.5-3.

A study was conducted to assess the level of Cr, Pb, Cd, Ni, Zn, Cu, Fe and Mn contamination in the sediment samples of the Buriganga river, at the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh. Total 14 sediment samples were collected from different areas of upstream of the Buriganga river. The mean concentrations of total Cr, Pb, Cd, Ni, Fe, Cu, Zn and Mn in the sediment samples were 173.4, 31.4, 1.5, 153.3, 481.8, 344.2, 12989 and 4036 µg g -1 , respectively. The range of pH and EC of sediment were 5.87-8.21 and 230-707 µS cm -1 , respectively. The mean value of organic matter in sediment samples was 13.4%. Heavy metal concentrations in sediment were compared with geochemical background and standard values, previous report on the Buriganga river and other rivers in Bangladesh. The average concentration of Cr, Pb and Ni in sediments of the Buriganga river is almost twice of the geochemical background i.e. average worldwide shale standard and continental upper crust value, Cd and Zn is about five times and Cu content is about ten times higher than the geochemical background values. Average concentration of Cr, Cu and Ni exceeded the severe effect level (SEL) values, where as Pb, Cd and Zn exceeded toxicity reference values (TRV). However, the concentration of heavy metal in the sediment samples of the Buriganga river for the year 2009 of the same river reported by corresponding author was relatively higher than this study average. The average Enrichment factors (EFc) for Zn, Cu, Mn and Cd reflects extremely contaminated pollution level which implies that these metals originated from point source of pollution and very severely enriched in river sediments. The pollution load index (PLI) of sediments of the studied region varied from 1.61-7.51. The geoaccumulation index (I geo ) for Cu of five locations was greater than 3.0, which exhibited strongly polluted sediment quality. The I geo for Mn in 11 locations and Zn in 12 sites were greater than 1.0, indicated moderately polluted sediment quality. Heavy metal pollution intensity in the Buriganga river water and sediments signaled alarming condition for city dwellers and aquatic ecosystem of the river. Sustainable steps and continuous monitoring on pollution prevention and cleanup operation is suggested to minimize pollution.

“…It is presumed that high EF c values indicate an anthropogenic source of trace elements, mainly from activities such as industrialization, urbanization, deposition of industrial wastes, and others. Since, the bioavailability and toxicity of any trace elements in sediments depend upon the chemical form and concentration of the elements (Kwon et al 2001), it can be inferred that trace elements in sediment samples with the highest EF c values, along with higher labile fractions in sediments have a potential for mobility and bioavailability on the aquatic ecosystems. Acevedo-Figueroa et al (2005) interpreted that EF c values of less than 1 indicate no enrichment; values of 1 to 3 indicate minor enrichment; 3 to 5 show moderate enrichment; from 5 to 10 enrichment is moderately severe; from 10 to 25 enrichment is severe; from 25 to 50 enrichment is very severe; and values over 50 indicate extremely severe enrichment.…”

The Tsurumi, a class-one Japanese river, has a significant metal loading originating from urban environment. Water and sediment samples were collected from 20 sites in winter and summer, 2009 and were analyzed to determine and compare the extent of different trace element enrichment. A widely used five-step sequential extraction procedure was also employed for the fractionation of the trace elements. Concentrations of zinc, copper, lead, chromium, and cadmium were three to four times higher than that of reference values and downstream sediments are much more polluted than the upstream sites. Geochemical partitioning results suggest that the potential trace metal mobility in aquatic environment was in the order of: cadmium > zinc > lead > copper > cobalt > chromium > molybdenum > nickel. About 80.2% zinc, 77.9% molybdenum, 75.3% cobalt, 63.7% lead, 60.9% copper, 55.1% chromium, and 39.8% nickel in the sediment were contributed anthropogenically. According to intensity of pollution, Tsurumi river sediments are moderately to heavily contaminated by zinc, lead, and cobalt. Enrichment factor values demonstrated that zinc, lead, and molybdenum have minor enrichment in both the season. The pollution load index (PLI) has been used to access the pollution load of different sampling sites. The area load index and average PLI values of the river were 7.77 and 4.93 in winter and 7.72 and 4.89 in summer, respectively. If the magnitude of pollution with trace metal in the river system increases continuously, it may have a severe impact on the river's aquatic ecology.
