The most common and abundant plastic found was polyethylene, which, in addition to 54% of the plastics found, was found in all samples. Polyvinyl chloride and nylon (10% each) are followed, while the remaining 26% are followed by 9 other polymers.
Researchers conclude that the method used is appropriate for the identification and quantification of microplastics in this type of tissue and hope it is useful for the study of toxicological risk.
In previous research, microplastics have also been found in other human samples, such as blood, intestine, and have been shown to be harmful to living things.
