The copper deposition on the platinum and palladium nanoelectrode has been studied using cyclic voltammetry. The use of nanoelectrode platinum and palladium are defined in the study of heavy metals. The noble nanoelectrode of metal has a typical silicone processing structure. In comparison to the nanoelectrodes, the geometry of the electrode series is complex and balanced. Nanoelectrodes of platinum are found effective in detecting heavy metal. There was regular analysis of the use of the sensors. The identification constraints down to the ng /L level was accomplished by refined electrode geometry and the stripping procedures. The process was used for the study of water sample determination. Another heavy metal ion attack voltammetric reaction was studied. The SEM picture clearly observed and characterized the nanoparticle electrode by X-ray diffraction and cyclic voltammetry.

The article is focused on estimation of Zinc in the roadside forages, and blood of buffaloes feeding on these forages. This study was carried out in Sargodha during December 2015 to January 2016 (winter) and May 2016 to June 2016 (summer). Five road sites (Mateela, Faisalabad roadside, Shaheenabad roadside, Bhalwal roadside and 50 chak) were selected from sampling of forages, soil and buffalo blood sample. Heavy metal analysis of all digested samples was done with atomic absorption spectrophotometer. Analysis of variance and correlation was done with two way ANOVA. This study regarding the accumulation of zinc in forages, soil and the buffalo blood would help the authorities to exactly determine the agents which are responsible for increasing pollution in the environment.
