Abstract

This article focuses on assessing the radiological and chemical toxicity of uranium in groundwater around the Manchanabele reservoir near Bengaluru, India. Analysis of 35 groundwater samples using LED fluorimetry revealed uranium concentrations ranging from 0.88 to 581.47 ppb, with about 34% exceeding the World Health Organization’s safe limit of 30 ppb. Radiological risk, measured as lifetime cancer risk, was generally low and within acceptable limits, while chemical toxicity, evaluated through hazard quotient (HQ), indicated potential health concerns in 12 samples where HQ exceeded 1. The study attributes elevated uranium levels to the region’s granitic geology and highlights a greater chemical toxicity risk compared to radiological effects for local residents.
