There was a high prevalence of some respiratory symptoms in the exposed group, including "cough" (64.1%), "sneezing" (60.6%) and "burning throat" (60.1%). Also, comparing respiratory symptoms in exposed and non-exposed groups showed that symptoms such as "cough" (p < 0.001), "sneezing" (p < 0.001), "burning throat" (p < 0.001), "shortness of breath" (p < 0.001), "chest heaviness" (p < 0.001), "hard breathing" (p < 0.001), "phlegm" (p < 0.001) and "voice change" (p = 0.001), which were more frequent in the exposed group, had significant correlation with the exposure to nanomaterials (Table 6).
