[Human Accumulation and Toxic Effects of Microplastics：A Critical Review].
AI summary Read the abstract
This review summarizes how microplastics enter the human body through food, drinking water, and air, and where they tend to accumulate in organs and tissues. Researchers found evidence that microplastics can trigger inflammatory responses and oxidative stress in the body. The study calls for more research into the long-term health effects of continuous microplastic exposure in humans.
The effect of microplastics on the ecological environment and human health has become a topical issue， and research on the risks and harmful effects of MPs on human health in particular has attracted widespread attention. Due to the characteristics of small size， low degradability， and easy migration， MPs continuously migrate from the environment to the human body， and their main exposure pathways are oral ingestion， inhalation， and dermal contact， with the main exposure media being food， drinking water， dust， personal care products， etc. MPs have been detected in organs， fluids， and excreta of digestive， respiratory， cardiovascular， reproductive systems， etc. The abundance range of MPs in the human body is 0-1 206.94 particles per gram. After entering the human body， MPs can cause cytotoxicity， mitochondrial toxicity， DNA damage， cell membrane damage， and other effects on human cells and organs， leading to serious consequences such as local inflammation， ecological imbalance， metabolic disorders， etc.， in various systems. Owing to their small specific surface area， they can also adsorb pollutants such as heavy metals， organic pollutants， antibiotics， pathogens， and harmful microorganisms， causing combined toxicity and immunotoxicity. In the end， we highlighted general deficiencies in existing studies and provided directions for future research on the influence of MPs on human health.

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.
