Antimicrobial resistance is considered to be one of the greatest global public health threats of the 21st century. The discharge of antibiotics into the environment may increase antimicrobial resistance a well as disrupt proper ecosystem functioning. Thus, evaluating the antibiotics present in Minnesota’s environment as well as contributing factors to their presence in their environment will provide invaluable information for improving water quality and protecting human and ecosystem health. This goal is being accomplished through sampling water and sediment at field sites across Minnesota variably impacted by human activity. Twenty-five antibiotics from various therapeutic classes used in both human and veterinary medicine have been quantified using liquid chromatography-tandem mass spectrometry to determine trends.
