Yamuna's dissolved oxygen (DO) level, that supports aquatic life, has plummeted to zero at different points in the river's journey through the national capital, a Delhi Pollution Control Committee study has found. The recent idol immersions aggravated its already alarmingly high pollution level, shooting up Biochemical Oxygen Demand (BOD), that indicates the level of organic pollution, the report says. According to DPCC, a waterbody has to have a minimum 4 mg/l of DO while BOD should not exceed 3 mg/l for aquatic life to thrive.
