HEAVY METALS DISTRIBUTION IN WATER AND SEDIMENT OF RIVER MANDAKINI IN CHITRAKOOT REGION OF MADHYA PRADESH PART *
R. K. Shukla and G. S. Gupta Department of Energy & Environment, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalay, Chitrakoot, Madhya Pradesh, India *Author for Correspondence ABSTRACT Heavy metal concentrations of river Mandakini in Chitakoot were assessed. The range observed for Fe, Cd, Pb, Cr, and Hg. in the river water was 1.871-52.54, 000-0.008, 000-0.11, 000-0.040 and 000-0.0002. ppm respectively. Similarly in sediment the range of Fe, Cd, Pb, Cr and Hg was 6301-25287 µg/gm, 000-1.99 µg/gm, 8.69-31.68 µg/gm , 8.69-31.68 µg/gm , and 1.20-2.90 µg/gm respectively. Arsenic was found absent both in water and sediment samples. The heavy metals accumulate in the aquatic life and through biomagnification may enter the food chain there by affecting the human beings as well. The research work was extended further to study the physico-chemical properties like temperature, pH, TDS, calcium hardness, Mg hardness, total hardness Cl- and NO3- values of the river water. Key Words: River Mandakini , Water ,Sediment, Heavy metals ,Physico-chemical parameters. INTRODUCTION Heavy metals such as cadmium, arsenic and lead can cause serve problems in aquatic environments due to their persistence, toxicity and tendency to accumulate in tissues. While constituents have been extensively studied, their chemical reactions in the environment and their overall effects on aquatic life are much complex and are poorly understood. It is well known that the fate and transport of metals in the environment is governed by the metals interactions and reactions with water sediments and aquatic organisms (Radhakrishnaiah et al., 1991). These sources of water supply are susceptible to pollution due to heavy human dependency on river waters. Notably indiscriminate dumping of waste and agricultural practices taking place in the areas prone to open dump for solid waste pit of latrines and septic tanks . These metals or their compound may be discharged from farmlands, municipal urban water runoffs, and agricultural activities into surface water and can cause pollution. They vary in type and include large quantities of raw materials, by-products, co-products, and final products of human activities.

MATERIALS AND METHODS Water and sediment samples were collected from six sites of river Mandakini during post monsoon (September, 2013). Sati Anusuiya, Sphatic Shila, Janki Kund, Ram Ghat, Karwi Bridge and Surya Kund. Water samples were collected the above sites from at 10-15 cm depth in pre-conditioned and acid rinsed clean polypropylene bottles (Ahdy and Khaled, 2009). The samples were immediately acidified with concentrated nitric acid to a pH below 2.0 to minimize precipitation and adsorption onto container walls (APHA, 2012). Surface sediment samples were taken at a depth of about 5 cm and immediately transferred into pre-cleaned polythene bags. The collected samples were oven dried at 400C for 48 hours, homogenised, sealed in clean polythene bags and then stored at 4 0C for further processing (Yongming et al., 2006; Suthar et al., 2009). The physico-chemical parameters were determined following the standard methods for the examination of water and wastewater (APHA). Sample Analysis For the determination of total heavy metals in the samples, procedures is described in APHA (2012) was followed. Hot plate digestion of water and sediment samples was carried out with tri-acidnitric-sulphuric and perchloric acid mixture. The digested samples were filtered through Whatman No 42 filters and made up to 25 ml by adding distilled water in a volumetric flask. Heavy metal concentrations were determined using atomic absorption spectrophotometer (AAS-303,Thermo Fisher Secentific, pvt Led. Mumbai,India) Chemicals and reagents used were of analytical grades. All glassware were washed with 14% HNO3 and rinsed thoroughly with double distilled and deionised water prior to use. Only double distilled and deionsed water was used for the study. RESULTS AND DISCUSSION The value of physico-chemical parameters measured in river Mandakini water at different sites are given in table 1 and figure 2. The pH ranged from 7.2-7.6 at all locations. The indicates alkaline nature of the Mandakini water TDS ranged from 243-295ppm, Ca hardness from 114-136ppm, Mg hardness from 76-100ppm, total hardness from 210256 ppm, chloride from 8.0-17.0ppm and NO3 from 2.33-10.5ppm. All the above values were with in the permissible limit prescribed by BIS. Heavy metals in the river Mandakini system The concentration value of heavy metal in water and sediments of river mandakini were presented in tables 2 and 3 and figures 3 and 4. The values of Fe in water an sediments ranged from 1.871-52.54ppm, and6301-25287 µg/g, respectively, which was higher than its permissible limit of BIS guideline. The observed values of Cd in water and sediments ranged from 000-0.008 ppm and 000-1.99 µg/gm respectively and were with in permissible limit as assigned by BIS guide line. The value of Pb in water and sediment ranged from 000-0.11ppm and 72.1-1874.7 µg/gm respectively. The above values were within permissible limit as assigned by BIS. The values of Cr in water and sediment ranged from 000-0.040ppm and 8.69-31.68 µg/gm respectively. These values were within permissible limit of BIS guide line. The value of Hg in water and sediment ranged from 000-0.0002ppm and 1.20-2.90 µg/gm respectively. The values of present study are within the prescribed permissible limit. Arsenic was absent in water as well as in sediment of the river during the study period.

Figure 4: The concentrations of heavy metals in river Mandakini sediment (µg/gm) CONCLUSION Heavy metals adsorbed on sediments have the potential to remobilise under altered environmental conditions like change in pH or physico-chemical content. Thus, sediments which act as sink of heavy metals can become immediate source of metal pollution of the water bodies. Regular environmental monitoring and assessment of aquatic resources with respect to heavy metals is necessary to study the impact of development projects and programmes on their water and sediment quality. Water and sediments both act as habitats of aquatic organisms. Any alternation in the quality of after and sediments is definitely going to affect the aquatic organisms. This may start sequential action ultimately affecting all forms of life including human beings.
