Detection and characterization of microplastics in the human testis and semen.
The health risk of microplastics (MPs) is a growing global concern. Evidence of reproductive health damage caused by the accumulation of MPs in males is still lacking. In the present study, 6 testis and 30 semen samples were collected, and MPs were detected using both pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and laser direct infrared spectroscopy (LD-IR). The results showed that MPs were detected in both testis and semen, with an average abundance of 0.23 ± 0.45 particles/mL in semen and 11.60 ± 15.52 particles/g in testis. Microplastics in the testis were composed of polystyrene (PS) with 67.7 %, while polyethylene (PE) and polyvinyl chloride (PVC) were the predominant polymers in semen. Compared to fragments, fiber, and film detected in semen, the fragment was the main shape the in testis. The sizes of these microplastics ranged from 21.76 μm to 286.71 μm, and most (67 % and 80.6 %) were 20-100 μm in semen and testis. In summary, this study revealed for the first time that MPs pollute the human male reproductive system and that various MP characteristics appear in different regions, which provides critical information and basic data for the risk assessment of MPs to human health.
期刊介绍:
The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere.
The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
