This book deals with the Introduction to various types of Environmental Pollution and diverse effects of Metal ion pollution. A fair Introduction was given about different kinds of Currents and their application in Analytical Chemistry. Production of Simple Catalytic & Catalytic Hydrogen Currents were explained with examples. Dithiocarbamte Chemistry was mentioned and two ligands such as Ammonium Piperidine Dithiocarbamate and Ammonium Morpholine Dithiocarbamate were synthesized and applied for the Estimation of Copper concentration in various Matrices of Environmental Importance at Dropping Mercury Electrode. The Results obtaines were compared with DIfferential Pulse Polarography in terems of Student-"t"-test and Variance Ratio "f"-test which indicated the statistical soundness of the Chapter. The developed was facile, sensitive, rapid and economical for the analysis of copper. This can also employed in commercial laboratories for routine quality control analysis.
