Abstract
Water bodies have been among the most frequently studied subjects due to the increasing anthropogenic input of pharmaceutical waste, which has been observed in recent times and severely impacts the ecosystems involved. To address this, a study was conducted using the Mapocho River as a sampling site, a location where the presence of pharmaceutical residues, including antimicrobial compounds, has previously been confirmed. Therefore, it can be inferred that at specific points with higher contamination levels, antibiotic-resistant bacteria may be present.
Through the characterisation and zoning of the water body under study, sampling was carried out, and the collected samples were subsequently subjected to laboratory analysis to evaluate bacterial resistance to antimicrobial compounds. Upon completion of this process, the results indicated the presence of antibiotic-resistant bacteria in the lower sector of the river, which could be related to contamination from pharmaceutical products. This helps identify the negative factors influencing the area due to the hazardous nature of this type of pollution.
