Benzo(a)pyrene and Gut Microbiome Crosstalk: Health Risk Implications.

This review delves into the impact of benzo(a)pyrene (B(a)P), which is a toxic and pervasive polycyclic aromatic hydrocarbon (PAH) and known carcinogen, on the human health risk from a gut microbiome perspective. We retrieved the relevant articles on each PAH and summarized the reporting to date, with a particular focus on benzo(a)pyrene, which has been reported to have a high risk of gut microbiome-related harm. B(a)P exposure can compromise the homeostasis of the gut microbiota, leading to dysbiosis, a state of microbial imbalance.

The widespread use of plastic products worldwide has brought about serious environmental issues. In natural environments, it's difficult for plastic products to degrade completely, and so they exist in the form of micro/nanoplastics (M/NPs), which have become a new type of pollutant. Prolonged exposure to M/NPs can lead to a series of health problems in humans, particularly toxicity to the nervous system, with consequences including neurodevelopmental abnormalities, neuronal death, neurological inflammation, and neurodegenerative diseases.

Article Synopsis
- Microplastics (MPs) and nanoplastics (NPs) significantly impact female reproductive health by weakening ovarian function and reducing fertility, as shown in animal studies.
- Continuous exposure to these pollutants increases oxidative stress and inflammation, disrupts hormone levels, and hampers gonadal development, potentially leading to carcinogenic effects.
- The review highlights the presence of micro/nanoplastics in human placental tissue, breast milk, and infant feces, raising concerns about their influence on maternal and fetal health, including risks for premature birth and pregnancy complications.

Micro/nanoplastics (MNPs), which are widely spread in the environment, have gained attention because of their ability to enter the human body mainly through ingestion, inhalation, and skin contact, thus representing a serious health threat. Several studies have reported the presence of MNPs in lung tissue and the potential role of MNP inhalation in triggering lung fibrosis and tumorigenesis. However, there is a paucity of knowledge regarding the cellular response to MNPs composed of polyethylene (PE), one of the most common plastic pollutants in the biosphere.
