India successfully executed one of the strictest lockdowns in the world during the height of the COVID-19 pandemic in early 2020, which provided unique opportunities to analyze the second-largest populous country's anthropogenic footprint on its natural systems. India's first Ramsar site and the world's second-largest brackish water system Chilika lagoon experienced a substantial decline (64%) in the total petroleum hydrocarbon (TPHC) level in water, which was attributed to the massive declines or, at times, an abrupt complete halt of motorized boat operations for fishing and tourism. Using the TPHC values during the lockdown period, our study recommends a TPHC baseline threshold of 2.02 μg L and 0.91 μg g for Chilika waters and sediment, respectively. These baseline values can be used to quantify oil pollution and to formulate policy and management action plans for Chilika lagoon as well as for other similar ecosystems by local environmental agencies.
印度在 2020 年初 COVID-19 大流行期间成功实施了世界上最严格的封锁之一，这为分析这个人口第二多的国家对其自然系统的人为影响提供了独特的机会。印度的第一个拉姆萨尔湿地和世界第二大咸水系统 Chilika 泻湖的水体中总石油烃 (TPHC) 水平大幅下降（64%），这归因于机动船捕鱼和旅游活动的大规模减少，有时甚至完全停止。利用封锁期间的 TPHC 值，本研究建议 Chilika 水域和沉积物的 TPHC 基线阈值分别为 2.02μg/L 和 0.91μg/g。这些基线值可用于量化石油污染，并为 Chilika 泻湖以及其他类似生态系统制定政策和管理行动计划，供当地环境机构使用。
