“…So heavy metal contents of production waters were calculated from the paper of books of the 16.-18. century (Table 5:). The results contained from process waters from the Rhine, Main and Moselle region around 1580-1700 are comparable to modern uncontaminated surface water (Pb 2+~ 1-10 µg/L), sometimes even higher than today [27]. Remarkable high values were determined in the process waters of the Netherlands around 1680-1735.…”

“…These essential metals can also produce toxic effects when the metal intake is excessively elevated (Tuzen, 2003). Studies on heavy metals in rivers, lakes, fish and sediments (Ozmen et al 2004;Begum et al 2005;Fernandes et al 2008;Ozturk et al 2008;Pote et al 2008 andPraveena et al 2008) have been a major environmental focus especially during the last decade. Sediments are important sinks for various pollutants like pesticides and heavy metals play a significant role in the remobilization of contaminants in aquatic systems under favorable conditions and in interactions between water and sediment (Rashed, 2011).…”

The study was conducted to investigate the heavy metal contamination in fishes and shrimps from the Passur River near the world famous Sundarban mangroves located in the southwestern part of Bangladesh, during the period from January to June 2013. The fish (Liza parse) and shrimp (Penaeus monodon) samples were collected from two stations as St-1 (Katakhali-1 km upper from port areaupstream) and St-2 (Amtola-1 km lower from port area-downstream) monthly for three months in January (winter), March (pre monsoon) and May (Monsoon). Before analysis, a bit of muscle, the whole liver and two gill arches from each fish and shrimp were removed. Samples of tissues from each fish and shrimp were removed, weighed and dried. A microwave digestion system was used to prepare the samples for analysis. After digestion residue diluted with 25 ml 2.5% HNO 3 . The water used was deionized and distilled. The metal analyses of samples (Cd, Cr, Cu, Pb and Zn) were carried out by using UNICAM-929 atomic absorption spectrophotometer (AAS) in SGS Bangladesh Limited, Dhaka-1205, Bangladesh. Among the heavy metals studied Cd, Cr, Cu, Pb and Zn were detected in fish and shrimp species were within acceptable limits by FAO standards. The results of this study indicated that a general absence of serious pollution in the Passur River is due to heavy metals; whereas the concentrations of elements found could mainly be attributed to geological sources. In this regard, to maintain the water and sediment qualities as well as the sound and safe aquatic life of the river need proper monitoring and management by the relevant authorities of the Government of Bangladesh.

“…There are various sources of heavy metals in this ecosystem such as anthropogenic activities like draining of sewage, dumping of domestic wastes and recreational activities. It may also occur in small amounts naturally through the leaching of rocks, airborne dust, forest fires and vegetation [2].…”
