“…The mineralogical origin in the Ganges alluvium is the main reason for higher concentrations of the above cations in the groundwater (Vinod 2012). Moreover, several reports illustrated that cation exchange processes and industrial activities also contribute to high Ca, Mg, Na and K ions concentrations in the study area (Naidu et al 1985;Singh et al 1997Singh et al , 2006. On the one hand, the silicate minerals that comprise most rocks did not react readily with most groundwater.…”

The study was carried out to understand the hydro-geochemistry and ground water quality in the Rajshahi City of Bangladesh. A total of 240 groundwater samples were collected in 2 years, i.e., 2009 and 2010 covering the pre-monsoon, monsoon and post-monsoon seasons. Aquifer soil samples were collected from 30 locations during the monsoon in 2000. All the samples were analyzed for various physicochemical parameters according to standard methods of analysis, these includes pH, electrical conductivity, total dissolved solids, total hardness, and total alkalinity, major cations such as Na -, Cl -, and SO 4 2-and heavy metals such as Mn, Zn, Cu, As, Cd and Pb. The results illustrated that the groundwater was slightly acidic to neutral in nature, total hardness observed in all samples fall under the hard to a very hard category. The bicarbonate and calcium concentration in the groundwater exceeded the permissible limits may be due to the dissolution of calcite. The concentration of calcium, iron, manganese, arsenic and lead were far above the permissible limit in most of the shallow tube well samples. The study found that the major hydrochemical facies was identified to be calcium-bicarbonate-type (CaHCO 3 ). A higher concentration of metals including Fe, Mn, As and Pb was found indicating various health hazards. The rock-water interaction was the major geochemical process controlling the chemistry of groundwater in the study area. The study results revealed that the quality of the groundwater in Rajshahi City area was of great concern and not suitable for human consumption without adequate treatment.

“…The sediment toxicity indicators such as contamination factor, contamination degree, pollution load index, geo-accumulation index, and the enrichment factors used in the present investigation for evaluating the sediment contamination caused by heavy metals have been previously used worldwide (Ideriah et al 2012;Ö zkan 2012;Moore et al 2009). Many other workers such as Borole et al (1982), Subramanian et al (1985Subramanian et al ( , 1987, Seralathan (1987), Ramesh et al (1990), Chakrapani and Subramanian (1990), Singh et al (1997), Kotoky et al (1997), Singh (1999), Singh et al (2013a, b, c) have been working on many other Indian rivers to investigate the geochemical environment of sediments. The present study of river sediments was carried out to assess the concentration of heavy metals of the river sediment.…”

The present study includes a systematic analysis of sediment contamination by heavy metals of the River Ghaghara flowing through the Uttar Pradesh and Bihar in Indian Territory. To estimate the geochemical environment of the river, seven heavy metals, namely Co, Cu, Cr, Ni, Cd, Zn, and Pb were examined from the freshly deposited river bed sediment. All the sediment samples were collected on a seasonal basis for the assessment of fluctuation in 2014-2015 and after preparation samples were analyzed using standard procedure. Result showed that heavy metal concentration ranged between 11.37 and 18.42 mg/kg for Co, 2.76 and 11.74 mg/kg for Cu, 61.25 and 87.68 mg/kg for Cr, 15.29 and 25.59 mg/kg for Ni, 0.21 and 0.28 mg/kg for Cd, 13.26 and 17.59 mg/kg for Zn, 10.71 and 14.26 mg/ kg for Pb in different season. Metal contamination factor indicates the anthropogenic input in the river sediment was in the range of (0.62-0.97) for Co, (0.04-0.26) for Cu, (0.68-0.97) for Cr, (0.22-0.38) for Ni, (0.70-0.93) for Cd, (0.14-0.19) for Zn, and (0.54-0.71) for Pb. The highest contamination degree of the sediment was noticed as 4.01 at Ayodhya and lowest as 3.16 at Katerniaghat. Geo-accumulation index was noted between (0 and 1) which showed that sediment was uncontaminated to moderately contaminated and may have adverse affects on freshwater ecology of the river. Pollution load index (PLI) was found highest at Chhapra which was 0.45 and lowest at Katerniaghat which was 0.35 and it indicates that the river sediment has a low level of contamination. Significant high correlation was observed between Co, Cu, and Zn, it suggests same source of contamination input is mainly due to human settlement and agriculture activity. Positive correlation between Zn, Co, Cu, Cr, and Ni indicated a natural origin of these elements in the river sediment. Cluster analysis suggests grouping of similar polluted sites. The strong similarity between Co, Zn, Pb, Ni, Cu, and Cd showed relationship of these metals come from the same origin, which is possibly from natural and anthropogenic input which was also confirmed by correlation analysis. Using the various pollution indicators it was found that the river bed sediment is less contaminated by toxic metals during the study but the sediment quality may degrade in the near future due to increasing anthropogenic inputs in the river basin, hence proper management strategies are required to control the direct dumping of wastewater in the river.

“…Among the worst environmental contaminants are the heavy metals which are elements with atomic number > 20, specific density > 5 gm/cm 3 human metabolic activity when taken in through the food chain [6]. These elements, which are non-essential and phytotoxic both at low as well as very high concentrations, are commonly detected in wastewaters and can be critical because of their persistence in the environment.…”

“…Human activities such as mining, landfill leachates, industrial emissions, vehicular emissions, fossil fuels, fertilizer erosion from agricultural run-off, herbicides and pesticides, sewage and municipal wastes all contribute to the accumulation of pollutants in nearby aquatic systems [1] [2], which are thought to be a safe site for disposal of polluted sediments [3]. Among the worst environmental contaminants are the heavy metals which are elements with atomic number > 20, specific density > 5 gm/cm 3 human metabolic activity when taken in through the food chain [6].…”

Freshwaters are not only used locally in many developing countries but they are often over exploited for domestic purposes, agriculture and disposal of industrial wastes which result in an overload of excess nutrients, harmful chemicals and heavy metals. Plant species together with sediments and water samples collected from eleven aquatic water bodies in the vicinity of industrial units in Kolkata were studied for their potential to uptake Pb, Cd and Cr under field conditions. Cd and Cr concentrations in the sediments were higher than background values considered to be toxic.Alternanthera philoxeroides and Eichhornia crassipes were the two invasive species present, with the former being more widely distributed. Among native plants, Ipomoea aquatica was the most abundant. Metal uptake in the plants differed among species, tissues and sites. Pb and Cd accumulation in root tissues for all plants in most sites suggested an exclusion strategy for metal tolerance. Since I. aquatica is widely consumed in many parts of SE Asia, its metal content should be checked before use since it was found to efficiently translocate both Pb and Cd from roots to shoots.The potential of A. philoxeroides as a metal excluder needs to be explored further since it translocates less to its shoots as compared to E. crassipes and I. aquatica.
