Although free metal ion concentrations of Cu, Pb and Cd were probed using ion selective electrodes, they were found below the detection limits of the electrodes. Among the total dissolved metals, zinc was found to be highest, i.e. 304.85iÂg/l at najafgarh drain, while lead was seen in the lowest concentration(0.05iÂg/l) at site ramghat, the entry point of the river into New Delhi. Lead concentration ranged between 0.05 to 1.37iÂg/l. The lowest level was found at ramghat and highest level at nizamuddeen bridge and okhla barrage. As expected Zn, Fe and Mn were seen in very high concentrations compared to the other elements namely Cu, Cr, Ni and Pb. In each site, the variation among the metal concentrations was highly significant. Similarly each of these metals also differed significantly(LSD, P<0.05) among the sampling sites. At down stream sites the percentage concentrations of chelex-labile metals, particularly Fe, Mn and Cu were lower than that of the upstream sites. This is attributed to the varied nature and amount of colloidal matter in the waters at these sites. Copper in the river water differed from the other metals in its behavior towards chelex-resin, probably for its strong association with the organic films on Fe and Mn colloids.

Spatial variation in the distribution of select nutrients and alkali and alkaline earth metals in... more Spatial variation in the distribution of select nutrients and alkali and alkaline earth metals in the top soil of three hillocks(Raktakonda, Galikonda and Chittamgondi) near Visakhapatnam(Araku valley) India was explored. The study was undertaken during November 2006 to January 2007. The soil samples were collected up to a depth of 10 cm as two 5 cm slices. The soil type in the mine area was acidic with clayey loam texture. Total organic matter(TOM), total nitrogen(TN) and total available sulphur(TAS) ranged from 16.27 to 56.51 %, 3467 to 7829 mg/kg and 3.71 to 332.40 mg/kg respectively. The lowest and highest values for chloride were 153.70 and 342.87 mg/kg. The exchangeable bases were in the order of Ca>Mg>K>Na>Li. Cation exchange capacity(CEC) was in the range of 39.2 to 187.5 meq/kg. Two-way ANOVA for pH, EC, TDS, and alkali and alkaline earth metals showed significant variation(P<0.05) among sites. Except for TOM, TN, TAS, Na and Li, all other nutrients/elements varied significantly (t-Test, P<0.05) between months. Among the alkali metals, K was positively correlated with Ca and Li. K, Ca and Li were positively correlated with TAS in soil, while Na was negatively correlated. Ca was negatively correlated with TN.
