| Resumo: | A wide range of pharmaceutical compounds can be detected in potable water in
concentrations ranging from ng/L to μg/L. Such compounds comprise the micropollutants
of emerging interest, and indiscriminate use can cause harmful effects human health.
Moreover, they are persistent in the aquatic environment, where they can cause a change
in the microbial community. However, the regulatory framework aimed at controlling the
pharmaceuticals occurrence in potable water is still incipient. This study aims to
investigate the occurrence of pharmaceutical compounds in potable water through a
systematic review of this topic in the scientific literature. For this purpose, a bibliographic
search was conducted in published literature between 2000 and 2021. Published data from
each paper (concentration, city, country, and analytical detection method) was analyzed
statistically. The information comprised 468 concentration data, distributed in 143
compounds in 17 countries worldwide. Maximum concentrations of Prednisone (6.323
ng/L), Caffeine (5.845 ng/L), Betamethasone (2.620 ng/L), Iopamidol (2.400 ng/L),
Triclocarban (2.055 ng/L) and Lincomicina (1.413 ng/L) were detected in Belo
Horizonte, Campinas, Ganges river (India) and Ontario (Canada), respectively.
Furthermore, the concentrations of Iopamidol, Ibuprofen, Diclofenac, Triclosan and
Carbamazepine exceeded the Australian guidelines for potable water by 2.4×, 1.4×, 4×,
2.1× and 2×, respectively. Despite the aforementioned data, the results indicate that there
is still little systematic monitoring or comprehensive studies on the occurrence of
pharmaceuticals in treated water. More studies should be developed in order to track the
sources of contamination and understand the risk to which the population is subjected by
the water supply. |
