ClearExposure routes of microplastics (MPs) to humans and possible risks of MPs to human health from food and the environment: a short review
This review summarizes how microplastics reach humans through food, water, and air, and discusses their potential health effects. Researchers found that seafood, drinking water, and airborne dust are the primary exposure routes, with microplastics carrying additional chemical contaminants that may amplify their harm. The study emphasizes the need for more research into the long-term health consequences of chronic microplastic exposure in humans.
Environmental pollution by microplastics and its consequences on human health
This narrative review examines how plastics discarded in the environment fragment into microplastics through environmental and biological stresses, accumulate across terrestrial and marine ecosystems, and enter human bodies primarily through seafood, drinking water, and air inhalation, summarizing documented toxicological consequences for human health based on literature published from 2017 to 2022.
The Impact of Microplastic on Human Health
This review synthesized evidence on microplastic exposure pathways and health effects in humans, finding that microplastics enter the body via ingestion, inhalation, and dermal contact and are associated with oxidative stress, inflammation, genotoxicity, and endocrine disruption.
Environmental exposure to microplastics: An overview on possible human health effects
This review examines the potential health effects of human exposure to microplastics through ingestion, inhalation, and skin contact. Researchers found that microplastic exposure may cause oxidative stress, inflammation, and immune system disruption, with the body's inability to break down synthetic particles potentially leading to chronic inflammation. The study emphasizes that while evidence of harm is growing, microplastic toxicity varies greatly depending on particle properties, concentration, and individual susceptibility.
MICROPLASTICS: Focus on Food and Health
This review covers the presence of microplastics in food and discusses their potential health implications, noting that humans are exposed through seafood, salt, drinking water, and other dietary sources. It summarizes current scientific understanding while acknowledging significant gaps in knowledge about long-term health effects.
Food Contamination by Microplastics and Human Health Implications
This review examines how food is contaminated by microplastics throughout the supply chain — from agricultural soil and irrigation water to food processing and packaging — and evaluates the health implications for human consumers. The authors estimate dietary microplastic intake across food categories and identify seafood, drinking water, and packaged foods as the highest-exposure routes.
Dietary microplastics: Occurrence, exposure and health implications
This review examined the occurrence, human exposure pathways, and health implications of microplastics in food. Researchers found that microplastics have been documented in fishery products, drinking water, sea salt, and other foods, with intestinal absorption considered limited due to particle size. The study suggests that while direct toxicity from ingested microplastics requires further investigation, the chemicals added during plastic manufacturing could potentially cross the intestinal barrier.
Potential risk assessment and toxicological impacts of nano/micro-plastics on human health through food products
This review examined the potential risks and toxicological effects of nano- and microplastics on human health through food products, identifying key contamination sources in the food chain and their harmful impacts on the body.
An Investigation into the Environmental and Human Health Implications of Microplastic Toxicity
This review synthesizes evidence on how microplastics are distributed throughout the environment, the routes by which people are exposed (food, water, and air), and the health effects documented in experimental studies. The authors find significant links between microplastic exposure and adverse health outcomes and call for urgent regulatory action and more research into long-term human health risks.
Toxic Effect of Food-Borne Microplastics on Human Health
This review compiles evidence that people ingest thousands of microplastic particles annually through everyday foods including drinking water, salt, fish, tea, and milk, and that these particles can cause cytotoxicity, inflammation, hormone disruption, and even neurotoxicity in experimental models. Microplastics can cross the gut lining and enter the circulatory system, potentially affecting organs throughout the body. The paper serves as a comprehensive summary of the known and suspected human health risks from food-borne microplastic exposure.
Review of micro- and nanoplastic contamination in the food chain
This review examines the contamination of the human food chain with micro- and nanoplastics, from seafood and drinking water to processed foods and packaging. Researchers found that while plastic particles are widely present in food and beverages, the actual health impacts on humans remain largely unknown due to inconsistent study methods. The study calls for standardized analytical approaches to properly assess dietary microplastic exposure and its potential risks.
Impact of Microplastics on Human Health through the Consumption of Seafood: A Review
This review synthesizes evidence on how microplastics in seafood pose health risks to humans upon ingestion, detailing how MPs spread through the digestive system to other organs and cause toxicological effects including oxidative stress, immune disruption, and metabolic changes.
The Environmental and Health Implications of Microplastics on Human and Aquatic Life
This review summarizes the harmful effects of microplastics on both aquatic ecosystems and human health, covering physical injury, chemical toxicity, and immune disruption in marine organisms. Researchers found that microplastics can accumulate through the food chain and potentially affect human health through seafood consumption and other exposure routes. The study highlights the urgent need for policy interventions to reduce plastic pollution at its source.
Micro- and nano-plastic contamination in foods and potential risk to human health
This review summarizes the current state of knowledge about micro- and nanoplastic contamination in food, covering sources, occurrence, and analytical detection methods. Researchers found that while various foods, especially seafood, contain measurable levels of microplastics, the health risks to humans remain difficult to assess due to inconsistent research methods. The study calls for standardized approaches to better evaluate dietary exposure and potential health impacts.
Plastic and Human Health: A Micro Issue?
This review evaluates the potential human health impacts of microplastic exposure through food and air, drawing on evidence from particle toxicology and related fields. Researchers note that if inhaled or ingested, microplastics could accumulate in tissues and cause localized inflammation, while chemical additives and adsorbed pollutants may leach out and cause additional toxic effects. The paper emphasizes that chronic, long-term exposure is likely the greater concern, though current data on actual human exposure levels remains limited.

This review examines how microplastics interfere with the food chain from soil and water through to human consumption, and summarizes adverse health effects including inflammation, endocrine disruption, and neurotoxicity reported in animal models.
Microplastics in our diet: A growing concern for human health
Microplastics smaller than 5 millimeters are entering our food through drinking water, salt, seafood, packaged food, and even alcoholic beverages. Once consumed, these particles have been detected in human blood, feces, breast milk, liver, and other tissues, showing they can accumulate throughout the body. Emerging evidence links microplastic exposure to inflammation, oxidative stress, gut problems, brain effects, reproductive harm, and cardiovascular risks.
Microplastics in Fish and Fishery Products and Risks for Human Health: A Review
This review summarizes existing research on microplastic contamination in fish and seafood products and the associated human health risks. Microplastics found in fish can carry harmful chemicals and pathogens, and once eaten by humans, they may cause oxidative stress and move from the gut to other tissues. The review highlights seafood as a major dietary source of microplastic exposure and calls for better monitoring and risk assessment.
