Surfactant additives in water-based metalworking fluids lead to strong biophysical inhibition of pulmonary surfactant film. (PubMed, J Hazard Mater) - "Here, to probe any potential adverse impacts of airborne MWFs on the biophysical and physiological functions of PS film that may help achieve a deep and comprehensive understanding of the pulmonary toxicology of MWFs, a systematic study on the interaction between an animal-derived natural PS (i.e., Calsurf) film and the aerosols of water-based MWFs and their different constituents is conducted using constrained drop surfactometry (CDS) capable of closely simulating normal tidal breathing and lung-related physiological conditions in vitro. It was found that the airborne MWFs can induce strong PS inhibitions once their accumulated amount in the environment attains 0.2 mg/cm3. And their inhibitory effects are demonstrated to mainly originate from the surfactant additives such as polyethylene glycol monooleate (PEGMO) that can desorb PS film from the air/water interface via competitive interfacial adsorption, although it has normally been regarded as an eco-friendly..."
