Appraisal of heavy metal status in water for irrigation usage of the Bangshi River, Bangladesh
Arefin, M. Taufique,Rahman, M. Mokhlesur,Wahid-U-Zzaman, M.,Kim, Jang-Eok The Korean Society for Applied Biological Chemistr 2016 Applied Biological Chemistry (Appl Biol Chem) Vol.59 No.5
An attempt was made to assess the status of heavy metals in the Bangshi River water for irrigation usage. River water was sampled from 20 sampling points for chemical analysis of physicochemical parameters and metal ions. Our analyses revealed that water samples were slightly alkaline to alkaline. All samples had reasonable electrical conductivity, and these samples were from low to medium salinity classes as being fit for irrigation on soils having moderate level of permeability. Water samples were categorized freshwater as per total dissolved solids (TDS). All water samples were excellent indicating low alkalinity hazard, based on sodium adsorption ratio (SAR), but most of the samples were doubtful to unsuitable for soluble sodium percentage (SSP). All samples were free from residual sodium carbonate (RSC) suggesting suitability for irrigation purpose. For water hardness, samples were rated as moderately hard, hard, and very hard. The status of Fe, Zn, Pb, Cd, and Ni in water samples were within permissible levels but Cr, Cu, and Mn content in water samples were in excess of recommended limits and these ions would be considered toxic in long-term irrigation system. Significant relationships existed between EC versus TDS, SAR versus SSP, SSP versus RSC, and SAR versus RSC. There were significant correlations between metal ions: Fe-Cu, Fe-Pb, Cu-Pb, Fe-Mn, Cu-Mn, and Mn-Pb. This finding showed that Cr, Cu, and Mn ions were considered contaminants in river water used for irrigation because the present status of these metals may pose a harmful impact on human health.

The aim of the present study was to evaluate the degree of metal contamination of the Turag River water and its suitability for irrigation. Twenty water samples were analyzed for physic℃hemical parameters and metals viz., calcium, magnesium, potassium (K), sodium, copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), lead (Pb), cadmium (Cd), chromium (Cr), and nickel (Ni). All water samples were slightly alkaline to alkaline. Regarding electrical conductivity (EC), all samples were suitable for crop in soils with moderate permeability and leaching. Water samples were medium salinity and low alkalinity hazard classes. In terms of total dissolved solids (TDS), all samples were classified as freshwater. As per sodium adsorption ratio (SAR) and soluble sodium percentage (SSP), all samples were classified as excellent. No residual sodium carbonate (RSC) was detected in any of the samples, indicating suitability for irrigation; and all samples were considered very hard. Cr and Mn contents in all samples were above FAO guideline values and, therefore, these metals were considered toxic. Zn, Cu, Pb, Cd, and Ni concentrations were below acceptable limit for irrigation and do not pose a threat to soil environment. Significant relationships were found between EC and TDS, SAR and SSP, SAR and RSC, and SSP and RSC. The combinations of ions such as K.Zn, K.Fe, K.Cu, K.Mn, K. Pb, Zn.Fe, Zn.Cu, Zn.Mn, Fe.Mn, Cu.Mn, Cu.Pb and Mn.Pb exhibited significant correlation. This study revealed that Turag River water samples are contaminated with Cr and Mn. This fact should not be ignored because water contamination by metals may pose a threat to human health through food chain.
