“…However, studies reporting the simultaneous occurrence of a wide range of contaminants in water bodies feature prominently in recent years. Such studies have provided evidence that pharmaceuticals co‐exist with other pollutants such as personal care products and pesticides in water bodies (Alves et al, 2022; Chafi et al, 2022; Xu et al, 2019). Hence, their simultaneous removal in water is important as some of these pollutants could cause severe environmental risks than pharmaceuticals.…”

The introduction of large amounts of pharmaceuticals into the environmental waters is well‐documented in literature with their occurrence reported in all different water matrices accessible to humans and animals. At the same time, the increasing consumption of coffee and tea‐based beverages results in the generation of solid waste, which is mostly disposed‐off in the environment. To minimize environmental pollution, coffee and tea‐based materials have been proposed as suitable options to remove pharmaceuticals in environmental waters. Therefore, this article provides a critical review on the preparation and applications of coffee and tea‐based materials in removing pharmaceuticals from contaminated water. In this context, most studies in literature focused on the applications of these materials as adsorbents, while only limited work on their role in degradation of pharmaceuticals is discussed. The successful application in adsorption studies is attributed to high surface areas of adsorbents and the ability to easily modify the adsorbent surfaces by incorporating functional groups that provide additional oxygen atoms, which promote easy interactions with pharmaceuticals. Hence, the adsorption mechanisms are mostly described by hydrogen bonding, electrostatic and π–π interactions with sample pH playing a dominant role in the adsorption process. Overall, the present article focused on the developments, trends and future research direction on the preparations and applications of coffee and tea‐based materials for efficient removal of pharmaceuticals in water. Practitioner Points Review of tea and coffee wastes application for removal of pharmaceuticals in water Key applications in adsorption and degradation of pharmaceuticals in water Removal mostly explained by hydrogen bonding, electrostatic, and π–π interactions Trends, gaps, and future research to be explored are reviewed and highlighted

Este estudo avaliou a ocorrência de 24 fármacos e desreguladores endócrinos em 13 mananciais de abastecimento de água do Brasil. Realizaram-se amostragens mensais da água bruta de mananciais lóticos e lênticos, por um período de até 13 meses, abrangendo os períodos de seca e chuva. Os contaminantes foram extraídos e concentrados por extração em fase sólida (SPE) e analisados por cromatografia de fase gasosa ou líquida acoplada à espectrometria de massas (GC-MS ou LC-MS/MS). O desregulador endócrino bisfenol-A (BPA) foi frequentemente detectado nas amostras de água (79%), seguido pelo antialérgico loratadina (LRT), em concentrações medianas de, respectivamente, 27,7 e 15,6 ng/L. A cafeína (CAF), estimulante, não foi detectada em nenhuma das amostras, indicando não ser um bom marcador de poluição antrópica. A Análise de Componentes Principais (PCA) permitiu correlacionar os compostos e suas concentrações com o tipo de manancial e o período de coleta. Foram observados dois clusters: um constituído por amostras de ambiente lótico, coletadas no período seco, que exibiram altas concentrações de estrona (E1) e estradiol (E2); e o outro, mais heterogêneo, associado a amostras coletadas principalmente em ambiente lêntico durante o período chuvoso. Embora algumas correlações tenham sido identificadas, a maior parte dos dados apresentou uma disposição homogênea, não permitindo a observação de um padrão claro entre a prevalência de contaminantes e o tipo de manancial ou período amostrado.
