Biological Effects of Microplastics: A Review.
Researchers reviewed how microplastics harm a wide range of living things, finding they cause physical damage, inflammation, oxidative stress, and reproductive problems in aquatic animals, while also carrying toxic chemicals and dangerous bacteria into organisms. Major gaps remain in understanding the effects of long-term low-dose exposure and the risks posed by even tinier nanoplastics.
Toxic Effects of Nanoplastics on Animals: Comparative Insights into Microplastic Toxicity
This review compares the toxic effects of nanoplastics versus microplastics across mammals, fish, and invertebrates, finding that nanoplastics generally cause more severe harm because their tiny size allows them to cross biological barriers and enter cells more easily. In mammals, nanoplastics can cross the blood-brain barrier and cause brain inflammation, liver and kidney damage, and reproductive problems that can even pass to future generations. The findings suggest that as plastics in the environment break down into ever-smaller particles, the health risks may actually increase.
