Variations in the Yamuna River Water Quality During the COVID-19 Lockdowns

The COVID-19 pandemic that emerged in Wuhan city of China December 2019 has adversely impacted the health and economy, society, other significant spheres human environment. severely economic activities, especially industrial production, transportation, tourism, hoteling industries. present study analyses impact varying severity lockdowns activities during various phases on water quality Yamuna river parameters like pH values, biological oxygen demand, chemical dissolved oxygen, total suspended solids, electrical conductivity. found a improvement with closing lockdowns. average levels concentration these were quite low lockdown period at 7.26 (pH value), 31.32, 136.07, 7.93, 30.33 mg/L, 1500.24 μS/cm compared to pre periods 7.53 (pH), 39.62, 116.52, 6.1, 57.2 mg/L 1743.01 for conductivity, respectively. In addition, strong positive correlation between COD BOD TSS period. major findings from could be instrumental making environmentally sustainable policies country’s development. There is also huge scope scaling up national level analyze rivers backdrop
