The effects of fly ash (68131748), which is the solid residue remaining after coal combustion and which is hypothesized to cause a new pneumoconiosis, were also investigated. There is strong evidence that the reduction of DPPC is characteristic of these pulmonary infections. Dipalmitoyl lecithin is a surfactant that is secreted by the lung alveoli, which reduces the surface tension and prevents the collapse of lung alveoli during expiration. Mason, Robert J.; Huber, Gary; Vaughan, Martha. Typically, an emulsion is a suspension of small droplets of one liquid in another liquid with which it is incapable of mixing. Cargill’s fluid lecithin portfolio includes both soy- and sunflower-sourced options.
