Objectives

  1. a) To study of the trace element composition of paddy/garden soils, surface and groundwater b) Trace element composition in rice grains collected from areas of high, low and non CKD prevalence regions, giving particular attention to potentially toxic metals such as U, Cd, Cr etc. c) Preparation of maps showing spatial distribution of trace elements in soils and that could be correlated with the available health statistics of CKD. d) To investigate the geochemistry and behavior of trace metals within the CKD prevalent regions in relation to pathways leading to human exposure.
