Regression Analysis Between Blood Lead and IQ of Villagers Living Around Sargipalli Leadmine Area

Blood samples collected from five different villages around a derelict Lead mine area of Sundargarh district of Odisha state, India, were analyzed by AAS for lead contents. The village Bharatpur is nearby to mining site and other villages are of 1km distance from each other in between 5km radius. The village Jhimirmaul is nearby to tailing dam and river Ichha nala, which is the main drainage system of the mine. A total of 363 blood samples were collected and IQ of each individual was analyzed using AAMR Adaptive Behavior Scale from the villages such as Bharatpur (BP), Sargipalli (SP), Jhargaon (JG), Jhimirimoul(JM), and Sribhubanpur (SB).Finally regression analysis between the two variables was made and obtained that IQ values are linear functions of Blood lead Concentration suggesting impact of Plumbism on Neural Coordination and Cognitive behavior.
