Microplastics And Nanoplastics: Environmental Sources, Human Exposure Pathways, And Potential Health Impacts
AI summary Read the abstract
This systematic review maps out the many ways microplastics and nanoplastics enter the human body, including through food, water, air, and everyday products. The researchers found these tiny particles are now present in nearly every environment, from oceans to our homes. The review highlights growing concerns about what this constant low-level exposure might mean for our long-term health.
Plastics have a profound impact on daily life, including packaging, medicine, and household items. Their disposal after single use and subsequent breakdown into micro- and nano-plastics raise significant concerns about their effects on ecosystems and human health. Microplastics and nanoplastics have emerged as ubiquitous contaminants in natural and human-made environments, including oceans, freshwater systems, and the atmosphere. These particles have been implicated in sources of human exposure including contaminated seafood, drinking water, and various food items, exacerbated by migration from packaging materials. This systematic review synthesizes current literature on the sources, pathways, and health impacts of these particles, focusing on human exposure and associated risks. Microplastics and nanoplastics can enter the human body primarily through ingestion, inhalation, and dermal contact, posing potential health risks such as oxidative damage, inflammation, and disruption of physiological processes in the gastrointestinal, central nervous system, nephrons and respiratory systems leading towards gastrointestinal disturbances, neurotoxicity, nephropathy, and respiratory diseases. This paper aims to inspire further studies to understand the full extent of microplastic and nanoplastic contamination, their interaction with biological pathways and the implementation of effective regulatory measures to mitigate human health risks associated with these particles.

From environment to body: sources and health consequences of microplastics and nanoplastics in humans
AI summary Read the abstract
This review summarizes existing research on how tiny plastic particles called microplastics and nanoplastics enter the human body through food, water, air, and skin contact. Studies cited suggest these particles may build up in tissues and are linked to inflammation, immune problems, and other health issues, though long-term human health risks remain unclear.
A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
AI summary Read the abstract
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.
Sources, Environmental Fates, Human Exposure Pathways, and Health Impacts of Micro- and Nanoplastics
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics are now found everywhere—in our food, water, and air—and this review pulls together what scientists currently know about how they get into our bodies and what they might do once there. The concern isn't just the plastic itself, but that these particles can carry along other harmful chemicals (like BPA and heavy metals) and may disrupt hormones and metabolism, with the smallest particles even able to slip past the body's natural protective barriers. The research is still catching up, though—scientists don't yet have long-term human studies to fully confirm the risks, so this paper mainly highlights what we need to study
