Reacción a "Microplastics found in reproductive fluids"

Without information on the sizes of the microplastic particles observed, it is challenging to interpret how meaningful this data is.  There is a high potential for samples to become contaminated with microplastic throughout the sampling, laboratory processing, and analysis procedures.  If stringent steps to minimise this are taken, other clues such as the size of the particles observed can be used to rule out such contamination, with there being a greater likelihood for smaller particles (<0.001 mm > 0.01 mm) being absorbed and redistributed around the body.  It is not a surprise that microplastics have been found – they are everywhere, even in the lab – but the data provided do not support that they are there as a result of human exposure as opposed to methodological artefact and must be interpreted with caution at this early stage.
