    Microplastics are defined as tiny pieces of plastic less than 5 mm in length (note: 5 mm is the maximum value, the smallest is invisible to the naked eye.


    Since then, a growing body of research has found that the supposedly untouched Antarctic ice sheet, the deepest Mariana Trench on Earth, and Everest, the top of the world, are all contaminated with plastic discarded by us human.


    Humans invest plastic waste in the environment, and the environment returns microplastic.


    However, scientists are still digging whether ingesting microplastics poses a significant risk to human healt.


    Recently, in a pilot study published in "Environmental Science & Technology Letters", researchers from Nankai University's School of Environmental Science and Engineering and New York University School of Medicine made a worrying finding: living in the same area as Compared with adults, neonatal viscera had higher concentrations of microplastic.


    On December 23, 2021, in a new study published in the top journal of environmental science "Environmental Science & Technology" (IF=028), research from the State Key Laboratory of Pollution Control and Resource Utilization, School of Environment, Nanjing University For the first time, the team found another worrying piece of evidence by examining stool samples from participants in 11 provinces and cities in China: Elevated levels of microplastics in the body may also exacerbate intestinal inflammatio.


    Plastics have long been considered inert, and when ingested, they pass through the gastrointestinal tract and are excreted through the biliary trac.


    For the new study, the researchers recruited 50 healthy volunteers, including 30 men and 20 women; and 52 participants diagnosed with inflammatory bowel disease, including 31 men and 21 wome.


    Inflammatory bowel disease (IBD) is a nonspecific chronic inflammatory disease of the bowel, mainly including ulcerative colitis and Crohn's diseas.


    Healthy participants in the study came from 10 provinces in China, including Jiangsu, Anhui, Henan, Hebei, Hubei, Jiangxi, Shandong, Shanxi, Sichuan and Guangdon.


    The researchers collected stool samples from all participants and collected a questionnaire about alcohol consumption, eating habits, and working and living condition.


    By analyzing the feces, the researchers found for the first time that the microplastics in the feces of the two groups of participants were similar in shape, mainly flakes and fiber.


    A total of 15 microplastics were detected in the feces of both groups of participants, the two most common being polyethylene terephthalate (PET) and polyamide (PA.


    The researchers found that participants with more severe IBD symptoms tended to have higher levels of fecal microplastic.


    Using questionnaires, the researchers found that participants in the two groups who drank bottled water, ate takeaway food, and worked with dust exposure had more microplastics in their fece.


    In conclusion, this study is the first to reveal significant differences in fecal microplastic concentrations between IBD patients and healthy individuals, suggesting that the characteristics of individual fecal microplastics can provide meaningful information for their health risk assessmen.
