The Takeaway
While microplastics are known to be everywhere, this is the first study to establish a 'job exposure matrix' showing that breathing them in at work leads to a significant decrease in lung capacity. It moves the conversation from environmental concern to a documented cause of occupational lung disease.
From the abstract
Background: Microplastics and nanoplastics (MNP) are an increasingly recognized component of airborne particulate matter, yet their impact on respiratory health is unclear. This study aimed to develop a job exposure matrix (JEM) for occupational exposure to airborne MNP (PlastiXJEM(R)) and examine its association with respiratory outcomes in the Lifelines cohort. Methods: Four experts scored occupational airborne MNP exposure levels (none, low, high) for all ISCO-08 occupations based on document
