Summary
Researchers screened 15 popular commercial brands of packaged food ice cubes in Mexico City and found microplastics in 100% of samples, with concentrations ranging from 19 to 178 particles per liter. The most common plastic types identified were polypropylene, polyethylene, and polyamide, predominantly in fiber form. The findings indicate that packaged ice cubes represent a previously unrecognized route of human dietary exposure to microplastics.
Concern over microplastics has grown tremendously, and they have been found in all environmental compartments; yet, much remains unknown regarding their impact on a variety of human-consuming food products. Here, we contribute to ongoing research by screening the 15 most popular commercial brands of packaged food ice cubes in Mexico City for microplastics. Microplastics were detected in 100% of the samples evaluated, with concentrations ranging from 19 ± 4 to 178 ± 78 L. There was a significant difference in the microplastic concentration across samples. The mean microplastic concentration was 79 ± 47 L, and the main types were polypropylene, polyethylene, polyvinyl alcohol, tygon polymer, sealing ring gardena 2824 large, polyamide 6, and cellophane. Moreover, microplastics that are fibrous (87%), non-colored (54%), and less than 300 μm in size (63%), were found to be more prevalent. The SEM-EDX analysis showed heterogeneous structural and morphological characteristics of microplastics, as well as traces of Si, S, Ti, Ca, Al, and Na. Furthermore, we estimate that ice cube consumption in Mexico City can result in the inadvertent ingestion of 4.9 × 10 ± 3.4 × 10-1 × 10 ± 7.2 × 10 microplastics annually. The findings of the study revealed that microplastics were identified in ice cubes and can be conveyed to humans, stressing the need of managing and eradicating such contamination from our food.
