Description
Rahat Khan and a team of co-authors measure chromium pollution in river mud near a relocated tannery in Bangladesh. Their study appeared in twenty twenty-six. Moving a dirty industry can just move its contamination, and the buried footprint is rarely mapped.
Sixty mud samples from eighteen sites on the Dhaleshwari River were tested for fifteen elements. Chromium at the outfall hit about two hundred sixty times the average crust level. Levels fell with distance, and half the samples passed a known harm threshold for wildlife. Layers near the surface in close cores were enriched, matching episodic dumping. Statistical unmixing blamed only a modest share of overall variation on human input, but that share was chromium-heavy. The risk screening flags the outfall zone.
