Microplastics are defined as small plastic particles between 1 µm and 5 mm in size. Due to poor waste management and plastic pollution, they are now documented to be ubiquitous in the environment.1,2 However, pathways of dietary exposure to microplastics are not yet fully understood. The consumption of bottled water has been calculated to increase by 7% annually, with an estimated mean total global consumption of bottled water to be 513 billion liters by 2025. This study demonstrates how the Agilent 8700 Laser Direct Infrared (LDIR) Chemical Imaging System can accurately identify and quantify the presence of microplastics in bottled drinking water. This study also shows the capability of the Agilent Cary 630 FTIR spectrometer to investigate the source of microplastic contamination.
