Disposable masks, formed mainly from polymers, often incorporate various chemical additives to enhance their performance. These additives, which include plasticizers, may be released during mask usage, presenting a novel source of human exposure these compounds. In this study, the presence 16 organophosphate esters (OPEs), 11 phthalates, and four alternative in types face were studied, as well release simulated use (artificial laboratory conditions). Total plasticizer concentrations exhibited minimal variation across different types, with mean values 7.27 µg/face for surgical, 8.61 reusable, 11.0 KN-95, 13.9 FFP2 masks. To explore behavior, inhalation experiments conducted under conditions. The findings revealed significant temperature-dependent enhancement subsequently increasing exposure. showed percentages, ranging 0.1 95 %, depending on specific compound type. Notably, OPEs percentage 1.0 similar 1.2 % release. Although plasticizers less frequently released, they still presented notable 4.1 %. Daily intake estimations via ranged 0.01 9.04 ng/kg body weight (bw)/day additives. Using estimations, carcinogenic non-carcinogenic risks associated compounds evaluated. All calculated studied paper remained below established threshold limits. However, do represent an additional pathway that, when considered alongside other more predominant routes such indoor/outdoor inhalation, dermal absorption, dietary intake, makes total worthy consideration.
