Abstract
Background: Scientists believe that the new coronavirus causing COVID-19 is airborne. It has been approved that wearing masks and hand washing prevent the spread of COVID-19. This study aimed to evaluate the association between wearing facemasks, hand washing, and COVID-19 contraction in the population of Tabriz, Iran.
Materials & Methods: In this analytical study, necessary information was collected via four online multi-optional questionnaires on sociodemographic characteristics, the COVID-19 virus, mask-wearing behaviors, and hand hygiene habits among 360 individuals (120 cases and 240 controls). Based on data normality, quantitative variables were reported as mean ± standard deviation or the median (min-max). In addition, the relationship between qualitative variables was evaluated by the Fisher’s exact test, and correlations were assessed by the Spearman's test.
Results: Elderly individuals and their care seekers had fewer potentials for exposure to COVID-19 (p = 0.010), but healthcare workers were at a higher risk of contracting the virus than other occupations (p = 0.002). In addition, smokers were at a lower risk of the disease than other healthy people (p = 0.009). Furthermore, the incidence of COVID-19 was significantly higher among individuals not wearing facemasks than others (p = 0.007).
Conclusions: we concluded that wearing a facemask was more effective than hand washing and antiseptics in preventing the incidence of COVID-19 contraction; thus, people not wearing facemasks were at a higher risk of the viral infection.

Abstract
Background: Printing industry workers face hazards from noise and lead exposure. This study investigates the combined effects of lead and noise on malondialdehyde (MDA) levels in these workers, as previous research has focused on isolated effects. This study aimed at assessing the impact of simultaneous lead and noise exposure on the health of people working in the printing industry.
Materials and Methods: Using TENMARS ELECTRONICS sound-meter following ISO9612:2009, malondialdehyde (MDA) levels were measured using Buege and Aust spectrophotometer Model CE1010 CECIL series 1000. Blood lead analysis followed NIOSH8003 method. Data were statistically analyzed using SPSS 20.0 with Pearson and ANOVA tests. The Kolmogorov-Smirnov test was employed to check the normality of the data.
Results: The study found that the die-cut unit had significantly higher daily noise exposure (mean ± standard deviation = 87.71 ± 1.469 dB) compared to other units. Additionally, the printing unit had significantly higher lead concentration (mean ± standard deviation = 0.1431 ± 0.02 ppb) and malondialdehyde (MDA) concentration (mean ± standard deviation = 0.9963 ± 0.238 mmol/lit) compared to other units.
Conclusion: The study found a strong link between blood lead levels and malondialdehyde (MDA) concentration in printing industry workers. However, no significant correlation was found between MDA levels and noise exposure or the combined exposure to noise and lead. These findings emphasize the need to address lead exposure in the printing industry to protect workers' health and prevent elevated MDA levels.
