“…It has also been observed that Zn with average value of 833.8 mgl À1 has been found well above the permissible limit 10 mgl À1 given by the WHO. This corroborate the pervious study carried out by Kumar, Singh, and Mahajan (2006), where it has been reported to be observed in the range 3e1044 mgl À1 .…”

Available online xxxKeywords: Radionuclide Uranium Radiological risk Toxicity Laser a b s t r a c tIn the present investigations, Laser Fluorimetry technique has been used for the microanalysis of uranium content in drinking water samples collected from different sources like the hand pumps, tube wells of various depths from wide range of locations in the four districts of SW-Punjab, India. The purpose of this study was to investigate the uranium concentration levels of ground water being used for drinking purposes and to determine its health effects, if any, to the local population of this region. Corresponding radiological and chemical risks have also been calculated for the uranium concentrations in ground water samples. Some other heavy elements have also been analysed using the Atomic Absorption Spectrometry. In this region, uranium concentration in 498 drinking water samples has been found to vary between 0.5e579 mgl À1 with an average of 73.5 mgl À1 . Data analysis revealed that 338 of 498 samples had uranium concentration higher than recommended safe limit of 30 mgl À1 (WHO, 2011) while 216 samples exceeded the threshold of 60 mgl À1 recommended by AERB, DAE, India, 2004.

“…However when compared with USEPA (2003) recommended level of 30 μg l −1 , all the analyzed samples from Upper Siwalik region and adjoining area of Punjab revealed uranium values below the safe limit. The uranium concentrations higher than 20 μg l −1 were generally observed in water samples coming from uranium rich zones (Kumar et al 2006). All the water samples have values less than 20 μg l −1 so these are safe for drinking purposes.…”

Uranium and radon concentration was assessed in water samples taken from hand pumps, natural sources and wells collected from some areas of Upper Siwaliks, Northern India. Fission track registration technique was used to estimate the uranium content of water samples. The uranium concentration in water samples was found to vary from 1.08 +/- 0.03 to 19.68 +/- 0.12 microg l(-1). These values were compared with safe limit values recommended for drinking water. Most of the water samples were found to have uranium concentration below the safe limit of 15 microg l(-1) (WHO, World Health Organization, Guidelines for drinking-water quality (3rd ed.). Geneva, Switzerland: WHO, 2004). The radon estimation in these water samples was made using alpha-scintillometry to study its correlation with uranium. The radon concentration in these samples was found to vary from 0.87 +/- 0.29 to 32.10 +/- 1.79 Bq l(-1). The recorded values of radon concentration were within the recommended safe limit of 4 to 40 Bq l(-1) (UNSCEAR, United Nations Scientific Committee on the Effects of Atomic Radiations, Sources and effects of ionizing radiation. New York: United Nations, 1993). No direct correlation was found between uranium concentration and radon concentration in water samples belonging to Upper Siwaliks. The values of uranium and radon concentration in water were compared with that from the adjoining areas of Punjab state, India.

“…The values of R (2) were 0.9716, 0.9699 and 0.9982 for lead (II), cadmium (II) and copper (II) ions, respectively, indicating the validity of the model. Table 4 shows similar results reported previously for biosorption of cadmium and other heavy metals.…”

“…Toxic heavy metals are released in the environment from a number of industries such as mining, plating, dyeing, automobile manufacturing, and metal processing (1). Cadmium is a toxic metal that occurs naturally in the environment and is considered as a pollutant emanating from industrial and agricultural sources (2). Adsorption is one of the methods for the removal of heavy metals from wastewater.…”

Background: Cadmium is a toxic metal that occurs naturally in the environment and is considered as a pollutant emanating from industrial and agricultural sources. Biosorption is a very simple and cheap technique for removal of metal pollutants from aqueous samples. Objectives: In this study, removal of cadmium from aqueous solutions using C. colocynthis fruit powder was studied. Materials and Methods:The effect of three parameters such as pH, initial concentration of cadmium and adsorbent dosage were optimized. For investigation of these parameters and exemption of optimal conditions the Box-Behnken design (BBD) was used. Results:The best results for percentage extraction of cadmium by C. colocynthis with BBD design was obtained at pH = 4.5, initial cadmium concentration of 31.22 and adsorbent dosage of 3.75 g/L. Analysis of variance (ANOVA) and R 2 = 0.98 showed that the model was able to predict the removal of cadmium by C. colocynthis fruit powder. Conclusions: Results of this research imply that the adsorption of cadmium was enhanced, by increasing the cadmium concentration and contact time. Based on the ANOVA results, the models report high R2 value of 99% for cadmium removal, which is very high and advocates a high correlation between the observed values and the predicted values.
