Potential planetary health impacts of the airborne plastisphere
AI summary Read the abstract
Researchers reviewed emerging evidence that airborne microplastics can carry and transport living microorganisms — including potential pathogens and antibiotic-resistant bacteria — across long distances through the atmosphere, identifying this as an overlooked global health threat that bridges pollution and infectious disease.
Plastics interact with microorganisms in ways that can profoundly affect ecosystems and human health. Despite their global atmospheric presence, microplastic-microbe interactions in air and their planetary health ramifications remain poorly understood. In this review, by synthesizing emerging evidence, we show that airborne microplastics could carry and sustain microorganisms over long distances and timescales, potentially dispersing pathogens, antibiotic-resistance genes, and other bioactive agents across ecosystems—highlighting an overlooked, multisector planetary health threat and research agenda.

Potential planetary health impacts of the airborne plastisphere
AI summary Read the abstract
This study examined the planetary health implications of the airborne plastisphere—microbial communities colonizing airborne microplastic particles—noting that these communities harbor pathogens, antibiotic resistance genes, and other hazardous organisms. The airborne plastisphere may facilitate the long-distance dispersal of microbial threats across ecosystems.
New insights into the microbial succession and health risks of atmospheric plastispheres
AI summary Read the abstract
Researchers conducted a two-month outdoor experiment to study how bacteria colonize atmospheric microplastics and found that while initial colonization was polymer-specific, communities gradually converged over time. Seven pathogenic species were specifically enriched on plastic surfaces, with some appearing only in later stages of biofilm development, suggesting that airborne microplastics may serve as carriers that accumulate and potentially transmit harmful bacteria.
Microplastics in air: a hidden public health threat
AI summary Read the abstract
This short review explains how microplastics become airborne from land, ocean, and industrial sources and are transported globally through the atmosphere, potentially entering the human body through inhalation. The author frames airborne microplastics as a hidden public health threat warranting greater scientific and regulatory attention.
It’s a matter of microbes: a perspective on the microbiological aspects of micro- and nanoplastics in human health
AI summary Read the abstract
Researchers highlighted an often-overlooked aspect of micro- and nanoplastic pollution: the microorganisms that colonize plastic particles and how they might affect human health. The study suggests that the microbial communities living on plastic surfaces, known as the plastisphere, could carry harmful bacteria into the human body through ingestion, inhalation, or skin contact, representing an additional health risk beyond the plastics themselves.
Ecological and human health risks of atmospheric microplastics (MPs): a review
AI summary Read the abstract
This review examined the ecological and human health risks associated with atmospheric microplastics, which are recognized as ubiquitous and persistent emerging pollutants. The study suggests that airborne microplastics represent a growing environmental concern requiring further investigation.
