Summary

This review documents how microplastics have permeated the human food chain and are now detected in human tissues including lungs, liver, placenta, and breast milk, examining exposure routes through ingestion, inhalation, and dermal contact and the potential health consequences of this ubiquitous contamination.

Microplastics (MP)—plastic particles smaller than 5 mm—have become pervasive environmental and dietary contaminants with potential health consequences. Plastic production has surged from 1.7 million tons in the 1950s to over 400 million tons today, and the resulting waste degradation has introduced MP into air, soil, and water. Humans are exposed mainly through ingestion, but also by inhalation and limited dermal contact. MPs are now detected in human tissues including lungs, liver, placenta, and breast milk.

The Impact of Microplastics on Human Health: a Comprehensive Review

This comprehensive review summarizes how microplastics — found in air, water, and food — enter the human body through ingestion, inhalation, and skin contact, and have been detected in organs including the lungs, liver, kidneys, placenta, and brain. Microplastic exposure has been associated with respiratory disorders, gut inflammation, reproductive toxicity, immune dysfunction, and potential neurological effects.

Microplastics in human food chains: Food becoming a threat to health safety

This review traces how microplastics enter the human food chain through both animal and plant sources, food packaging, and beverages. Once consumed, microplastics can accumulate in tissues and release harmful chemicals like plasticizers and heavy metals inside the body. The study emphasizes that food has become a major exposure pathway for microplastics and calls for stricter regulation of plastic use in food production and packaging.

Human Exposures to Microplastics

This chapter provides a comprehensive overview of how humans are exposed to microplastics through food, water, air, and consumer products. Researchers discuss the various pathways by which microplastics enter the human body and review evidence of their detection in organs including the liver, lungs, colon, and placenta, as well as in blood, breast milk, and saliva. The study highlights the need for biomarker-based approaches to better understand the health implications of microplastic accumulation in human tissues.
