The Gruesomeness of Microplastics: Food Contamination, Human Exposure, and Health Risks
AI summary Read the abstract
This review summarizes over 200 studies on tiny plastic particles called microplastics, which are found in air, soil, water, and food. It looked at how these particles enter the human body through eating, drinking, breathing, and skin contact, and discusses links to inflammation, oxidative stress, and hormone disruption reported in the research.
Plastics, once addressed as a revolutionary, effective, and beneficial invention, have now become a global environmental nightmare due to the alarming rise of microplastic pollution. This form of pollution is increasingly being recognized as a serious global disorder. Microplastics, whether originating directly from primary sources or from the degradation of larger plastic waste, are now pervasive in the air, soil, and aquatic environments. These microscopic particles are easily ingested both directly and indirectly by a wide range of organisms, including humans, eventually entering the human food chain through bioaccumulation. Owing to their minuscule size, microplastics can infiltrate the human body through multiple exposure routes primarily via food and water consumption, inhalation, and dermal contact. These exposure pathways raise significant health concerns, as microplastics are linked to various adverse effects, including inflammation, oxidative stress, endocrine disruption, and potential long-term toxicity. The objective of this review article is to comprehensively explore the entry pathways of microplastics into the human body and examine their associated biotoxicity and health risks. For this purpose, over 200 relevant studies were reviewed to gather a well-rounded understanding of the growing threat posed by microplastic contamination.

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.
