<div>AbstractPurpose:<p>Recent evidence suggests a significant association between microplastic (MP), forever chemicals, and plasticizers and various diseases, including cancer. In this study, we evaluated circulating levels of plastic-associated chemicals in relation to lung cancer incidence and mortality among smokers in the Prostate, Lung, Colorectal, and Ovarian (PLCO) study.</p>Experimental Design:<p>Using mass spectrometry, we screened for 29 known MP, forever plastics [per- and polyfluoroalkyl substances (PFAS)], and plasticizer chemicals in 245 sera collected preceding a lung cancer diagnosis and 1,200 noncase sera from participants in the PLCO study who had a history of smoking. Five PFAS and three plasticizers were detected and quantified in sera. A PFAP model, consisting of perfluorooctane sulfonate (PFOS) + perfluorohexanesulfonic acid (PFHA) + mono-iso-nonyl phthalate, was developed for predicting lung cancer mortality and risk strata based on quantiles established.</p>Results:<p>Higher circulating levels of PFOS, PFHA, and mono-iso-nonyl phthalate were associated with increased risk of lung cancer death (<i>P</i> < 0.05) but not incidence. Compared with the lowest quantile (reference), individuals with PFAP scores in the highest quantile were at markedly higher risk of death from lung cancer (<i>P</i> < 0.0001), with respective cause-specific and subdistributional HR of 1.86 [95% confidence interv...
