Patna: A recent study has revealed the presence of uranium (U-238) in the breast milk of several lactating mothers across different districts of Bihar, raising concerns about potential health risks for infants. The research, carried out by scientists from multiple institutions, examined 40 breast milk samples and detected uranium in every single one of them.
Speaking to ANI, Dr. Ashok Sharma of AIIMS Delhi, a co-author of the study, explained that although uranium was found in all samples, the overall levels were below permissible international limits. He further added that 70 percent of the infants showed indications of potential non-carcinogenic health risk, but the detected concentrations are unlikely to cause significant harm in real-life conditions. According to the study, the highest average contamination was recorded in Khagaria, while the highest individual uranium concentration came from Katihar district.
The researchers noted that prolonged uranium exposure in infants could affect kidney development, neurological functions and cognitive abilities, including reduced IQ and developmental delays, if the exposure continues over many years. However, they strongly emphasized that breastfeeding should not be stopped, as breast milk remains the safest and most beneficial form of nutrition for infants unless a doctor advises otherwise.
Globally, the World Health Organization (WHO) recommends a provisional limit of 30 micrograms per liter for uranium in drinking water, while some countries follow stricter limits. In India, uranium contamination in groundwater has been reported across 151 districts in 18 states, with Bihar also contributing to the affected regions.
Although the study highlights an important public health concern, experts maintain that the current uranium levels detected in breast milk are not expected to cause immediate harm, but call for continuous monitoring of groundwater sources and environmental safety measures to prevent future risks.
