ClearTransgenerational impacts of micro(nano)plastics in the aquatic and terrestrial environment
This review summarizes research on the transgenerational impacts of micro- and nanoplastics, showing that exposure can harm not only the directly exposed organisms but also their unexposed offspring. Researchers found that the most commonly reported effects across generations include tissue bioaccumulation, impaired growth and reproduction, oxidative stress, and genetic damage. The study highlights that particle characteristics such as size, polymer type, and degree of aging significantly influence the severity of these transgenerational effects.
The plastic brain: neurotoxicity of micro- and nanoplastics
This review examines the emerging evidence that micro- and nanoplastics can reach the brain in both aquatic animals and mammals, potentially causing neurotoxic effects. Researchers found that exposure to these particles induces oxidative stress, inhibits key enzymes involved in nerve signaling, and alters neurotransmitter levels, which may contribute to behavioral changes. The study highlights that systematic research comparing different particle types, sizes, and exposure conditions is urgently needed to understand the neurological risks.

From natural environment to animal tissues: A review of microplastics(nanoplastics) translocation and hazards studies
This review summarizes how micro- and nanoplastics travel from the environment into animal bodies through water, food, air, and even skin contact, then move through the bloodstream to accumulate in organs. Once inside, these particles cause oxidative stress, inflammation, gut damage, reproductive harm, and nervous system effects across many animal species. The findings strongly suggest that similar pathways of exposure and harm could apply to humans.
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.
