Deep in the Australian outback, sparrows are helping monitor lead exposure in children living near lead mines in Broken Hill and Mount Isa. Researchers found that sparrows, who live intimately with people, can predict lead poisoning levels in kids by sampling their blood. The study highlights the ongoing issue of lead contamination in Australian towns, despite the phase-out of leaded fuel. Sparrows offer a practical and cheaper way to identify contamination hotspots, potentially aiding in monitoring health risks for people. The research can extend to other heavy metals and pollutants, showcasing the innovative use of birds in environmental monitoring.
