In this investigation, lead in roadside soil at Thirparappu falls (S1), Muttom Beach (S2), Mandaikadu Beach (S3), Chothavilai Beach (S4) and Kanyakumari Beach (S5) were examined. Soil samples were obtained at different satiation. The concentrations of lead were determined using atomic absorption spectroscopy. Lead values in soil samples ranged from 13.81 to 35.2 ppm. Lead studies revealed that there was significant contamination in soil affected by traffic intensity. Cyclic voltammetry was used to explore the electrochemical behaviour of Pb at these electrodes in different supporting electrolytes. Soil extract is pH adjusted and examined with a modified carbon electrode using stripping voltammetry. The amount of detection for the electrochemical analysis was calculated as range between 10 and 35 ppm.
