“…A study of spatio-temporal variations in water quality of NullahAiktributary of the river Chenab, Pakistan by Qadir et al (2008) revealed that the quality of upstream water is better than that of downstream water. The information on water quality and pollution sources is important for implementation of sustainable water-use management strategies (Sarkar et al, 2007;Zhou et al, 2007;Bu et al, 2009).…”

The physico-chemical parameters and some heavy metal concentrations in the Logone River water at Moundou City, Chad, are studied for two stations from July 2013 to December 2014, one upstream and another downstream of the city. Standard methods are used. A total of twenty-two physico-chemical parameters were determined by spectrophotometers showed clear seasonal variations of; BOD 5, COD, sulphate, phosphate, and nitrate, among the stations. The Moundou City wastewater negatively impacted the concentrations of physicochemical parameters of Logone River water samples when compared with the World Health Organization (WHO) permissible limits. It was observed that the water quality parameters exceed the permissible limits downstream of the river:BOD 5 (198mg/l), COD (897 mg/l), MES (287 mg/l), F(1.87 mg/l), heavy metals Cr (0,934 mg/l), Fe (5,55 mg/l) Cu (0,294 mg/l), Pb (17 mg/l), As (0,894 mg/l), Mb (14,2 mg/l). This study shows that industrial discharge into Logone River seriously contributes to the pollution of the river at the level which poses health and environmental hazards to those using it in downstream for domestic and agricultural purposes.

“…The concentration of heavy metals was in the range of Zn, Cr, Pb, Cu, Cd and Hg. Gupta et al (2009) have reported that the concentration of Zn in the water of river Ganges at Allahabad was highest and followed by Pb, Cu, Cr and Cd, The high content of Zn and the lowest content of Hg were also reported by Jain and Sharma (2001), Sarkar et al (2007) and Malik et al (2010). The concentrations of heavy metals were highest in summer 6.0 -6.5 6.0 -6.8 6.8 -7.9 6.8 -8.6 6 and the lowest in rainy months due to the dilution effect of water.…”

Heavy metals like cadmium, zinc, copper, chromium, lead and mercury were measured in the various tissues of Labeo rohita and Channa striatus and in the water samples collected from the Kolleru Lake, Andhra Pradesh during 2009-2010. The concentrations of heavy metals in the different organs of fishes varied. In L. rohita, the concentrations of heavy metals were in the order of liver > kidney > gills > muscles and in C. striatus, it was liver > kidney > gills > muscle. The values of heavy metals concentration in the present study are within the maximum permissible levels for drinking water and fish.

“…A significant ecological change is pronounced in this area due to reclamation of land, deforestation, huge discharges of untreated or semi-treated domestic and municipal wastes and effluents from multifarious industries such as tanneries, chemicals, paper and pulp, pharmaceuticals, (as shown in Fig. 1) as well as contaminated mud disposal from harbour dredging (Sarkar et al 2007b). All of these factors impart a variable degree of anthropogenic stresses leading to elevated concentrations of both heavy metals and persistent organic pollutants (POPs).…”

Abstract:This paper documents the concentration of total arsenic and individual arsenic species in four soft-bottom benthic polychaetes (Perenereis cultifera, Ganganereis sootai, Lumbrinereis notocirrata and Dendronereis arborifera) along with host sediments from Sundarban mangrove wetland, India. An additional six sites were considered exclusively for surface sediments for this purpose. Polychaetes were collected along with the host sediments and measured for their total arsenic using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Arsenic concentrations in polychaete body tissues varied greatly, suggesting speciesspecific characteristics and inherent peculiarities in arsenic metabolism. Arsenic was generally present in polychaetes as arsenate (As V ranges from 0.16 -0.50 mg kg -1 ) or arsenite (As III ranges from 0.10 -0.41 mg kg -1 ) (30 to 53% as inorganic As) and dimethylarsinic acid (DMA V ; <1 to 25%). Arsenobetaine (AB; <16%), and PO 4 -arsenoriboside (8 to 48%) were also detected as minor constituents, whilst monomethylarsonic acid (MA V ) was not detected in any of the polychaetes. The highest total As (14.7 mg kg -1 dry wt) was observed in the polychaete D. arborifera collected from the vicinity of a sewage outfall in which the majority of As was present as an uncharacterized compound (10.3 mg kg -1 dry wt) eluted prior to AB. Host sediments ranged from 2.5 to 10.4 mg kg -1 total As. This work supports the importance of speciation analysis of As, because of the ubiquitous occurrence of this metalloid in the environment, and its variable toxicity depending on chemical form. It is also the first work to report the composition of As species in polychaetes from the Indian Sundarban wetlands.
