Occurrence and fate of emerging contaminants in water environment: A review

Lomefloxacin—Occurrence in the German River Erft, Its Photo-Induced Elimination, and Assessment of Ecotoxicity

“…Selected physico-, photo-chemical, and mass spectrometric properties of LOM are collected in Table 1.

“…Numerous recent studies have confirmed the presence of various anthropogenic micropollutants in water bodies [1][2][3]. These micropollutants include pharmaceuticals, personal care products, steroid hormones, and pesticides.…”

“…Hence, they enter the aqueous environment where they become ecotoxicologically hazardous. The regular observation of micropollutants during environmental monitoring is often associated with an increasing bacterial resistance formation [1][2][3][4]. Observed concentrations range from a few ng L −1 to several µg L −1 .…”

Can global pharmaceutical supply chains scale up sustainably for the COVID-19 crisis?

“…The environmental impacts occurring throughout the life cycles of these pharmaceutical products will also be magnified by the sheer scale at which they are administered as the pandemic progresses. For example, unmetabolized drugs and their metabolites are widely regarded as emerging trace pollutants which are problematic because conventional sewage treatment plants cannot destroy them (Gogoi et al, 2018). The quantity of these trace pollutants in sewage will certainly increase during the pandemic, and unnecessarily so if the drugs are used indiscriminately.…”
