"doxycycline" - 1 õppematerjal

Summary of three scientific articles

I chose three articles on the issue that dissert the topic of antibiotics in wastewater. To begin with, for years scientists have been aware of the potential problems of antibiotics being present in wastewater. For now, the research of engineering professor Olya Keen is showing that treatments to clean wastewater may actually be creating new antibiotics and further contributing to the development of antibiotic resistance in the environment. Keen is studying doxycycline, one of the widely used class of antibiotics. Their research to date is showing that chlorine used to treat wastewater is actually changing the makeup of the doxycycline and forming new antibiotics. Subsequently, the question arises: how do all the antibiotics find their way into wastewater? Olya Keen answers: ”Those that are not broken down by the organisms are passed to wastewater, also, expired antibiotics from homes and hospitals are dumped into wastewater.”
