This study investigates the distribution and bioavailability of toxic trace metals in soil and their uptake by plants, focusing on lead, cadmium, zinc, and copper in Tirupati soil samples. The research details the methodology for determining these metals using differential anodic stripping voltammetry (DPASV) and validates the findings through ICP-AES and AAS. Furthermore, the work assesses the suitability of the analyzed soil for agricultural purposes and its potential for preparing secondary reference materials.

This work presents a focused scientific analysis of trace metal contamination in soil, employing established analytical techniques for quantification and validation. The research directly addresses critical environmental concerns regarding soil health and agricultural viability. Its findings are pertinent to environmental scientists, agriculturalists, and researchers involved in material standardization.
