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.

Reports of the omnipresence of microplastics have mainly focused on their presence in the environment, but there is a growing interest in investigating the health impacts of microplastics. Many people would assume that infants' exposure to microplastics would be limited. However, infant formula was found to be a possible exposure pathway. Extracting and isolating microplastics from infant formula can be difficult due to the range of formulations, ingredients, and components, such as fats, proteins, minerals, vitamins, and sugars. This application note demonstrates the importance of quality control in microplastics analysis. The study also shows how the Agilent 8700 Laser Direct Infrared (LDIR) Chemical Imaging System can accurately identify and quantify microplastics in infant formula.
