Alarming amounts of microplastic debris discovered in Earth's air according to worldwide analysis
In a groundbreaking investigation, the PlasticDustCloud project has shed light on the widespread presence of airborne microplastics, marking a significant step in understanding this growing environmental issue. The comprehensive study, involving 12 sites across nine countries and three continents, has confirmed that microplastic pollution is a global air quality concern.
The study, led by Eurofins Environment Testing microplastics peer group in collaboration with the World Health Organization (WHO), sampled various countries and continents, including remote regions like the Pyrenees in Europe and parts of Asia.
The results of the study show a wide range, with a median of 143 particles per square metre per day, and a high of 3,110 micrograms per square metre per day. Urban areas have recorded up to 1,300 microplastic particles per square metre per day.
Key findings from the study highlight variations in microplastic deposition rates across different sites and detection technologies. Researchers used a standardised wet-dry deposition method for sampling, ensuring consistency in data collection.
The detection of microplastics in human lungs, blood, and breast milk has raised concerns about potential long-term health impacts. As these tiny particles, measuring less than 5 millimetres, travel through the atmosphere and reach remote regions, the need for further research and action becomes increasingly urgent.
The PlasticDustCloud project underscores the importance of international collaboration in addressing this global issue. As the world continues to grapple with the effects of microplastic pollution, further research is needed to fully understand the extent of this problem and to develop effective strategies for mitigation and prevention.
