Microplastics and Nanoplastics Impair the Biophysical Function of Pulmonary Surfactant by Forming Heteroaggregates at the Alveolar–Capillary Interface
Scientists found that micro and nanoplastics from common products like foam packaging, lunch boxes, and water bottles can impair the function of pulmonary surfactant, the crucial substance that keeps our lungs from collapsing.
