Nanoplastics

A new study published [blank] Cell Reports reveals that oral exposure to nanoplastics, or plastic particulates smaller [blank] 500 nanometers, can affect brain function in mice by inducing inflammation in the gut. The researchers found that nanoplastics [blank] more readily taken up by macrophages in the intestines than larger microplastics, and triggered the production of pro-inflammatory cytokines. This cytokine then affected the brain [blank] the gut-brain axis, resulting in cognitive and memory impairments. The authors hope that their findings will raise awareness of the potential health risks of nanoplastic pollution, [blank] is a growing environmental concern. They estimate that humans consume about 5 grams of plastic per week, equivalent to a credit card. The study adds to a growing body of evidence that microplastics and nanoplastics can have adverse effects on various biological systems, including the reproductive, immune, endocrine, and nervous systems. Previous studies [blank] shown that aquatic species and laboratory animals in contact with plastic particulates exhibit neurotoxicity and endocrine disruption.The authors also note that microplastics have been detected in human tissues, highlighting the need for more research [blank] the impact of plastic pollution on human health.
