ABSTRACT:

In present investigation analysis of water was done during monsoon, winter and summer seasons for metal content of river Beas in Himachal Pradesh during the year 2014-15. Metals such as Calcium (Ca), Magnesium (Mg), Potassium (K), Sodium (Na), Copper (Cu), Iron (Fe) and Lead (Pb) were analyzed from six sampling stations i.e. Beaskund, Shamshi, Pandohdam, Dharampur, Nadaun and Pongdam in the study area. The analysis of data reveals that Ca, Mg, K, Na, Cu were found to be within acceptable limit prescribed by WHO, 2011 and BIS, 2012. However, Cd   and Pb were found to be higher than acceptable limit prescribed by WHO, 2011 and BIS, 2012. The presence of higher concentration of heavy metals such as Cd and Pb due to their toxicity and bioaccumulation has adverse effect on the health of living beings including humans. The study indicates that water of river Beas needs constant bio monitoring.

Introduction

River basins play an important role in development of human settlements. Major civilizations often appeared where fresh water was most accessible and plentiful. River basins are useful units for management of water resources(Smith and Gleick, 2012). Most of rivers of Himachal Pradesh are perennial and main rivers are the Ravi, the Chenab, the Sutlej, the Yamuna and the Beas (WCD, 2000). The Beas river originates from Beas Kund near Rohtang pass. The river is 464 km long and have catchment area of 9920 km2 (Kujur, 2013). The river water quality is highly variable in nature due to environmental conditions such as basin litho logy, climate and vegetation (Ashu and Parveen, 2010 and Chauhan and Flora, 2010). The major natural sources of dissolved and soluble matter carried by river are atmospheric inputs of material, degradation of terrestrial organic matter and weathering of surface rocks (Chauhan and Sagar, 2013 and Sharma and Walia, 2016). With rapid development in agriculture, mining, urbanization, industrialization, hydro electrical generation, motor vehicle pollution and above all growth of population, river water contamination with hazardous waste is becoming common phenomena (Kumar, et al.2010; CPCB, 2013 and Sharma and Walia, 2015). The discharge of commercial and industrial waste water, treated and untreated domestic sewage, solid waste containing metal salts and some agricultural practices such as fertilizers and biocides create multiple environmental hazards for mankind and sustenance of aquatic life (Ritu and Manoj, 2012). Contamination of river water with toxic metals, prevent the further use water for industrial, agricultural and drinking purposes. In addition to this many ground water resources and rivers may have higher metal concentration due to geochemical origin of salts. Naturally occurring heavy metals can be present in some areas in sufficient concentration to create pollution problem. Although, trace elements are biologically beneficial in low concentrations but long term exposure to sub lethal concentration may result in adverse chronic biological effects. In recent years heavy metal concentration has increased to dangerous levels to living environment in many regions (Ong and Kamaruzzaman, 2009; Faudzi, et al.2014 and Malik, et al.2014). The pollution in river system has increased which has not only degraded the quality of water but has also affected the flora and fauna. In this context the present study was undertaken to assess the concentration of various metals in the river Beas, so that suitability of water for irrigation and drinking purpose can be ascertained.

Materials and Methods

The present study covered about 256 km stretch of river Beas, extending from Beas Kund, Kullu district to Pongdam (Maharana Partap Sagar) in Kangra district of Himachal Pradesh. In order to assess the concentration of Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), Cadmium (Cd), Copper (Cu), Iron (Fe), Lead (Pb) content in water of river Beas, six sampling stations i.e. 1 Beaskund (SS-1), 2 Shamshi (SS-2), Pandoh Dam (SS-3), Dharampur (SS-4), Nadaun (SS-5), and Pongdam (SS-6) were selected on the basis of identified pollution problem and upon the location of point of source of waste water discharge in the selected stretch of river Beas. The water samples were collected at about 15cm depth from three points, at one third. middle, two third of water across the section of river using dip and grab sampling method using pre rinsed polythene bottles.  Three water samples were collected during monsoon season, post monsoon season (winter) and pre monsoon season (summer) every fifteen days in the year 2014-15. All the samples were preserved with conc. HNO3 (3ml/L) and conc. HCl (0.5ml/200ml) solution (RANKAM, RFCL) for analysis at Environtech Laboratory Mohali, Punjab, India, using standard methods (APHA/AWWA/WEF, 2012)  and other methods (Maiti, 2004). Calcium and Magnesium were determined by EDTA method. Sodium and Potassium were determined using Microprocessor Flame Photometer (Environmental & Scientific Instruments 1382). Iron was determined using Spectrophotometer (Environmental & Scientific Instruments 2373). Cadmium, Copper and Lead were determined using Flame Atomic Absorption Spectrometry (LABINDIA AA7000), after appropriate calibration according to standard calibration procedures. All the data obtained was subjected to statistical analysis mean and standard deviation.

Results and Discussion

The results of concentration of various metals recorded during present investigation with mean value and standard deviation values are presented in Table 1-4.

Calcium

The mean concentration of Ca in study area of river Beas was 16.69±2.64 mg/L, with monsoon season recording lowest concentration of 13.03±5.92 mg/L and winter season recording highest concentration of 19.17 ±5.58 mg/L. The mean value of calcium was within the acceptable limit of 75mg/L prescribed by BIS, 2012.

Magnesium

The mean value of Mg in the study area of river Beas was 4.54± 0.80 mg/L and was within the acceptable limit of 30mg/L prescribed by BIS, 2012.

Potassium

Potassium occurs widely in environment and natural water sources and is an essential element for human beings. The mean value of K in the study area of river Beas was 1.93± 0.31 mg/L. WHO, 2011 and BIS, 2012 has not prescribed any guideline value of Mg.

Sodium

Sodium is found virtually in all foods and drinking water. The mean value of Na in the study area of river Beas was 12.44± 6.41 mg/L. WHO, 2011 and BIS, 2012 has not prescribed any guideline value of Na.

Cadmium

Cadmium is an element that occurs naturally in earth crust in the form of various organic compounds and as complexes with naturally occurring chelating agents. It is widely used in fertilizers, batteries, industry and plastics. The pollution of water with Cd results from mining, application of fertilizers and tobacco products. The summer season recorded highest concentration of 0.007 mg/L, whereas mean value of Cd in the study area of river Beas was 0.0037 mg/L, which was higher than the acceptable limit of 0.003 mg/L prescribed by WHO, 2011 and BIS, 2012. Prolonged exposure to higher concentrations of Cd cause severe health problems as it ranks next to mercury in toxicity.

Copper

Copper is both a nutrient and drinking water contaminant. The mean value of Cu in the study area of river Beas was 0.0012 mg/L which was within the acceptable limit of 0.5mg/L prescribed by BIS, 2012.

Iron

Iron is one of the most abundant metals in earth’s crust and is found in natural waters. It is an essential element to almost all living things, from microorganisms to human beings. The mean value of Fe in the study area of river Beas was 0.83±0.67 mg/L which was higher than the acceptable limit of 0.3 mg/L prescribed by BIS, 2012. However WHO, 2011 has not proposed any guideline value for drinking water.

Lead

Lead is most common of the heavy elements and is found in all human tissue and organs, though not needed nutritionally. Lead is used in paints solders, acid batteries and alloys. It is also used as lubricant and anti knocking agent in vehicle fuels. The continuous exposure to lead is associated with anoxia, nausea, impaired renal function and hypertension (Kaur, 2012 and Verghese, 2015). The mean value of Pb in the study area of river Beas was 0.02 mg/L, which was higher than the acceptable limit of 0.01 mg/L prescribed by WHO, 2011 and BIS, 2012. The contamination of river water may have been due to burning of fossil fuel by vehicular traffic along the river Beas and weathering of galena rocks in the study area. The presence of higher concentration of heavy metals such as Cd and Pb due to their toxicity and bioaccumulation has adverse effect on the health of living beings including humans (Das and Kaur, 2001). The study indicates that water of river Beas needs constant bio monitoring and present data can be used as baseline data.
