Abstract
Background: In most industries, employees are in contact with various chemical agents. The objective of this study was to assess the health risks posed by occupational exposure to harmful chemical agents in a pesticide manufacturing plant in Zahedan, Iran, in 2013.
Materials and Methods: This cross-sectional study was conducted in different units of a pesticide manufacturing plant. In order to evaluate the health risks associated with occupational exposure, a method provided by the Singapore Health Department was used. After identifying the pollutants, including benzene, toluene, ethylbenzene, and xylene (BTEX), CO, NO, NO2, and H2S, the degree of risk, the degree of exposure of the employees to the chemical agents, and the level of health risk were calculated.
Results: The results showed that the highest hazard rate (HR) in all units was related to benzene and the lowest HR was related to NO and H2S. In the powder unit, the exposure rate (ER) and risk rate (RR) of NO2 were higher than other pollutants. Additionally, in different units, the RR of benzene was 2.23, which was the highest among the pollutants. Generally, the RR of all pollutants was very low (insignificant) and low.
Conclusions: By using information related to the risks of chemical agents and results of assessments of the health risks of exposure to chemical pollutants, different occupations can be ranked in terms of exposure to chemical risk factors. This ranking can be used to prioritize the allocation of resources for control measures and reduce exposure levels to acceptable levels.

Abstract
Background: Firefighting and rescue require high physical and psychological needs under unpredictable and dangerous conditions. Thus, this study aimed to investigate mental workload and affecting factors in firefighters.
Materials and Methods: This is a descriptive study which was conducted on 250 firefighters of Tehran, Iran. National Aeronautics and Space Administration Task Load Index (NASA-TLX) survey was used in order to evaluate the mental load among firefighters. This tool evaluates mental workload in 6 areas of mental need, physical need, time pressure, endeavor level, performance (efficiency) and disappointment level. Each area is investigated with a scale from zero to 100. Finally, data were analyzed using descriptive statistics, Pearson correlation test and linear regression.
Results: The mean and standard deviation (SD) of age in firefighters was 32.20 ± 4.54 years. The physical load dimension (93.48 ± 8.93) had highest value and disappointment and failure feeling (25.85 ± 23.38) had the lowest value in terms of mental workload. Association with educational level and the physical load was direct and significant (P = 0.035). None of the demographic variables including age, working history, educational level, marital status, as well as being smoker had an impact on total mental workload (P > 0.050).
Conclusions: Overall mental workload was high in firefighters which can influence working efficiency and increase errors in this occupational group. Hence, implementing effective programs for adjusting mental workload such as ergonomic and psychological interventions are recommended for reducing mental and psychological errors and stress.

Abstract
Background: Work-related musculoskeletal disorders (WMSDs) are from among the most prevalent occupational health problems leading to high costs and reduced productivity in nurses. Therefore, the present study aimed at investigating musculoskeletal disorders (MSDs) in nurses and their correlation with demographic factors and awareness of ergonomics at the selected hospitals of Shahid Beheshti University of Medical Sciences in 2018.
Materials and Methods: This descriptive study was performed on 150 nurses of the selected hospitals of Shahid Beheshti University of Medical Sciences. Research data were collected using the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and the ergonomic knowledge questionnaire. In addition, descriptive statistics, the Kolmogorov-Smirnov test, the Chi-square test, and the Spearman’s test were used to analyze the data.
Results: The mean and standard deviation of the age and work experience of the participants were 32.67 ± 8.63 and 7.44 ± 8.84 years, respectively. Approximately 67.3% (101 individuals) had a bachelor’s degree. According to the results, the average level of the nurses’ awareness of ergonomics, working conditions, and occupational injuries were 3.14 ± 0.72 (medium level), 0.68 ± 2.58 (very weak level), and 0.95 ± 2.10 (very weak level), respectively. The awareness of ergonomics and working conditions in all areas had a significant negative correlation with the severity of discomfort (p<0.05).
Discussion: The results showed that the nurses’ awareness of ergonomics and working conditions were medium and poor, respectively. In addition, it was demonstrated that the use of ergonomic interventions to improve working conditions could play a significant role in reducing the nurses’ occupational injuries.

Abstract
Background: Due to their difficult working conditions, physicians are prone to injuries and musculoskeletal disorders affecting different parts of the body. This study aimed to investigate the prevalence of musculoskeletal disorders among physicians at Mortaz hospital in Yazd, Iran (2020)
Materials and Methods: The present study is a cross-sectional descriptive study conducted on 50 physicians at Mortaz Hospital in Yazd. The Nordic questionnaire and the Quick Exposure Check (QEC) method were employed to assess the prevalence of musculoskeletal disorders and analyze body postures at work. Chi-square and t-test were used to determine statistically significant relationships.
Results: Seventy percent of the subjects were male. The mean age of the samples was 47.3 ± 8.4 years. The point prevalence of musculoskeletal disorders in the lower back, neck, and knees were 52%, 30%, and 24% respectively; and the periodic prevalence of these disorders were 56%, 38%, and 34% in the back, neck, and shoulders respectively. According to the QEC results, 76% of the subjects needed further investigation and intervention in the future, and 20% were at an unacceptable risk level needing to be addressed immediately.
Conclusion: Physicians are exposed to many risk factors due to the working conditions that make them prone to various musculoskeletal disorders. Hence, to reduce the risk and prevalence of musculoskeletal disorders, interventional measures should be taken.

Abstract
Background: Noise is an important occupational safety and health issue in many workplaces. Noise annoyance is a strong measurable mental response. It is a reaction that a person expresses to the noise exposure. Thus, this study investigates the correlation between noise exposure and its annoyance in terms of mental health components.
Materials and Methods: This was a correlational descriptive study conducted on 100 workers. Respondents were recruited by a simple random sampling method. The equivalent sound level (LeqA) was determined using dosimetry. The numerical scale of ISO/TS 15666:2003 was used to measure noise annoyance. Mental health components were determined using the SCL-90 mental health questionnaire. Data analysis was performed in SPSS software (version 22) using Mann-Whitney, Kruskal–Wallis, and correlation tests.
Results: The median of mental health and noise annoyance were 38 and 6.5, respectively. A positive correlation was observed between equivalent sound level (LeqA) and noise annoyance score (P<0.001, r=0.92). A significant correlation was found between mental health components (depression, anxiety, self-morbidity, obsession and compulsion, aggression, morbid fear, paranoid thoughts, psychosis, and sensitivity in interpersonal relationships) and equivalent sound level (P<0.001). Also, a significant correlation was observed between noise annoyance score and mental health components (P<0.001).
Conclusion: We concluded thatin order to enhance the mental health of employees and increment efficiency and performance, it is recommended that appropriate control methods should be applied.

Abstract
Background: The outbreak of COVID-19 has a serious crisis for health systems in different countries. This study aimed to investigate the association between COVID-19 anxiety and cognitive failure and temperament components in the personnel of a hospital in the Yazd Province.
Materials and Methods: This was a cross-sectional study. The participants were the personnel of a hospital. The convenience sampling method was used for the sampling purpose. The participants were the personnel of COVID-19 and non-COVID-19 sections of a hospital. Data collection tools included a demographic questionnaire, the Corona Disease Anxiety Scale (CDAS), the Cognitive Failure Questionnaire (CFQ), and the Emotionality Activity Sociability (EAS) Questionnaire. Data analysis was performed in SPSS-24 software.
Results: The mean age of the participants was 33.45 (6.42) years. COVID-19 anxiety was significantly higher in the non-COVID-19 personnel than in the COVID-19 personnel (P < 0.001). In addition, a positive correlation was found between COVID-19 anxiety scores and cognitive failure scores (P = 0.04). After investigating the simultaneous relation of COVID-19 anxiety with cognitive failure and temperament components, the model results showed that cognitive failure (P = 0.02) and sociability (P < 0.001) had a significant effect on COVID-19 anxiety.
Conclusions: High levels of COVID-19 anxiety in non-COVID-19 section personnel indicated the importance of paying more attention to all hospital occupations. To reduce cognitive failure and anxiety, it is recommended to provide psychological training, workloads reduction, and the number of personnel be increased.

Abstract
Background: Noise pollution is one of the known harmful factors in workplaces. Noise can have different psychological consequences. Noise annoyance (NA) and noise sensitivity (NS) are seen as mediators in the study of noise impacts. The present study was conducted to investigate the association between NA and NS with psychological distress (PD).
Materials and Methods: This cross-sectional study was conducted among 115 textile workers. The sampling method was stratified random sampling. Noise exposure (NE) was determined by a noise dosimeter. NA, NS, and PD were assessed using Noise Annoyance Scale (NAS), Weinstein's Noise Sensitivity Scale (WNSS), and Kessler Psychological Distress Scale, respectively. Data analysis was performed in SPSS-22 software.
Results: The median (interquartile range) of NA was equal to 7 (3). The mean (standard deviation) of NS was equal to 66.33 (15.76). The results showed that there is a positive and significant association between equivalent sound level, and PD (P=0.01, r = 0.23). The results of our study showed that PD had a significant difference in diverse levels of NA (P=0.01) and NS (P<0.001).
Conclusion: In general, the annoyance caused by NA and NS can affect people's PD. Therefore, it is suggested to pay attention to these factors in studying the consequences of noise exposure.
