Microplastics are becoming a major global environmental concern with regular major newsworthy studies revealing the presence of plastics and microplastics in remote geographic locations, or as contaminations in many different consumer products, especially food and beverages, as well as within the digestive systems of marine species. The sources of the microplastics can be primary microplastics, i.e. materials that are specifically designed or manufactured to be of small dimensions, or secondary microplastics that start off as larger materials but are broken down in the environment into smaller fragments. Microplastics were initially defined as being plastic materials below 5mm in size, but the definition is now more commonly stated as plastic particles between the size 1mm down to the micron level, although there is no globally accepted definition.

Bulk plastic pollution in the environment is a major visible concern and needs to be addressed. However, microplastics are of the size that are not always visible to the human eye, but their impact is significant to the health of aquatic and marine species and can ultimately end up in the human food chain. Microplastics have also been detected in a wide range of other food and beverage products, including bottled water, despite bottled water being advertised as being the clean, natural, healthy alternative to tap water.

Analysis of both environmental samples and consumer products containing microplastics is essential to determine their prevalence and their impact. A range of analytical techniques have been applied to the analysis of microplastics. Of the techniques adopted, infrared (IR) spectroscopy, and more specifically IR microscopy/imaging, is the primary analytical technique for the detection and identification of microplastics. This webinar will give details on the use of the IR microscopy and imaging techniques and describe the optimum sampling and sample cleanup procedures employed. Results will be shown highlighting the detection and identification of microplastics present in a variety of different bottled water products.

The webinar will answer the following questions:

  • What are the best sample collection and clean up procedures for a range of sample types or sample origins?
  • Which IR sampling modes are best applied to microplastic samples?
  • Are bottled waters free from microplastics?
