Pharmaceuticals and personal care products (PPCPs) are receiving global scientific attention due to their occurrence, persistence and risk to aquatic and terrestrial organisms. In this study, we investigated the occurrence of 19 PPCPs in 6 lakes and River Nag in the city of Nagpur, India. Grab samples were collected and screened by LC–MS/MS. A total of 13 compounds were detected. In the multiple-site monitoring study, metformin (19–94 µg/L) and triclosan [upto 74.3 µg/L] were identified as the major PPCPs. In the single-site study (performed for 2 days at 2-hour interval), a spike was observed in the evening of Day 1, for example, atenolol (0.39–35.9 µg/L), metoprolol (ND-26.4 µg/L), acetaminophen (1.64–14.2), naproxen (0.5–15.9 µg/L), etc. The maximum number of compounds were detected in Lake Futala (13), followed by Gandhisagar (7), Khindsi (6), Ambazari (4), Koradi (4) and Gorewada (1). Triclosan and methylparaben were the major compounds in lake samples.

印度西部城市水环境中的药品和个人护理产品

药品和个人护理产品 (PPCP) 因其发生、持久性和对水生和陆生生物的风险而受到全球科学界的关注。在这项研究中，我们调查了印度那格浦尔市 6 个湖泊和纳格河中 19 种 PPCP 的发生情况。采集样品并通过 LC-MS/MS 进行筛选。共检测到 13 种化合物。在多站点监测研究中，二甲双胍（19–94 µg/L）和三氯生 [高达 74.3 µg/L] 被确定为主要的 PPCP。在单点研究（以 2 小时为间隔进行 2 天）中，在第 1 天的晚上观察到一个峰值，例如阿替洛尔 (0.39–35.9 µg/L)、美托洛尔 (ND-26.4 µg/L )、对乙酰氨基酚 (1.64–14.2)、萘普生 (0.5–15.9 µg/L) 等。 在 Futala 湖中检测到的化合物数量最多 (13)，其次是 Gandhisagar (7)、Khindsi (6)，Ambazari (4)、Koradi (4) 和 Gorewada (1)。三氯生和对羟基苯甲酸甲酯是湖泊样品中的主要化合物。
