Article Synopsis
- - Microplastic pollution in food is a growing global concern, affecting various types of food and drinks, leading to potential harm for both humans and the environment.
- - Microplastics have been found in human bodily fluids like blood and breastmilk, but their specific health effects are still largely unknown, despite some studies indicating they could harm organs and DNA.
- - Research on microplastics is complicated due to various factors such as size, shape, and chemical additives, making it essential to understand their presence in food and associated health risks.

Article Synopsis
- Humans face rising exposure to environmental toxicants, which can harm male reproductive health and contribute to infertility through damage to the reproductive system caused by factors like heavy metals and plasticizers.
- The testicular immune microenvironment (TIM) plays a crucial role in healthy testicular function, and more research is needed to see how environmental toxins might disrupt TIM and lead to reproductive issues.
- The review highlights the impact of various pollutants—especially heavy metals, plastics, and emerging contaminants—on male infertility and stresses the need for understanding reproductive immunotoxicology to develop effective prevention and treatment strategies.

The surge in face mask use due to COVID-19 has raised concerns about micro(nano)plastics (MNPs) from masks. Herein, focusing on fabric structure and polymer composition, we investigated MNP generation characteristics, mechanisms, and potential risks of surgical polypropylene (PP) and fashionable polyurethane (PU) masks during their wearing and photoaging based on stereomicroscope, μ-Fourier transform infrared spectroscopy (μ-FTIR), and scanning electron microscope (SEM) techniques. Compared with new PP and PU masks (66 ± 16 MPs/PP-mask, 163 ± 83 MPs/PU-mask), single- and multiple-used masks exhibited remarkably increased MP type and abundance (600-1867 MPs/PP-mask, 607-2167 MPs/PU-mask).

Micro-/nanoplastic contamination in agricultural soils raises concerns on agroecosystems and poses potential health risks. Some of agricultural soils have received significant amounts of micro-/nanoplastics (MNPs) through plastic mulch film and biosolid applications. However, a comprehensive understanding of the MNP impacts on soils and plants remains elusive.
