“…[18] Furthermore, Neghab et al investigated the effect of formaldehyde on the prevalence of respiratory disease symptoms and pulmonary function parameters and reported semi-acute reversible and chronic irreversible reduction in pulmonary function parameters. [19] A reduced FVC due to exposure to formaldehyde has also been reported by Akbar-Khanzadeh et al who investigated formaldehyde effects on the personnel of the anatomy lab. [22] The results of our experiment confirm those of above-mentioned studies.…”

“…[18] Based on the studies carried out by Neghab et al, exposure to formaldehyde results in some respiratory symptoms and causes semi-acute reversible and chronic irreversible reduction of pulmonary function. [19] Since the vast majority of personnel in the hospitals are exposed to formaldehyde and its adverse effects and because this group of society provides service to save people's life and to promote health level of the society, improving the health measures of this group seems to be one of the most important tasks of health and treatment authorities so that the damage to these people can be kept at the minimum level during their professional career. The aim of this study was to assess the effects of formaldehyde exposure on the pulmonary function test (PFT) in hospital staffs.…”

Background and Aim:Air pollutants such as formaldehyde can affect lung functions and make distortion in gas changing of lungs. The volumes and the flows of each breath can be measured with spirometer test. The aim of this study was to assess the effects of formaldehyde exposure on the pulmonary function test in hospital staffs. Material and Methods: This cross-sectional study was conducted in a hospital and involving 60 participants (30 staffs in exposed group and 30 staffs in control group). The measurement of formaldehyde concentration was using method 3500 national institute for occupational safety and health. In this study, a questionnaire was used to evaluate and determine the prevalence of respiratory symptoms. Spirometry test was used to evaluate the parameters of pulmonary function in two groups. t-tests and Chi-square as statistics tests were used to create data analysis. Results: The respiratory symptoms showed a significant difference between exposed group and control group (P < 0.05). Furthermore, parameters of pulmonary function forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow in the exposed group and the control group were significantly different (P < 0.05). Conclusion: Our study showed that exposed group with formalin has complex disorder of both restrictive and obstructive types.

“…A large body of evidence on workers who deal with pesticides has reported different health consequences including dermal 5 and respiratory problems, 6-8 hematological and biochemical impairments, 9,10 as well as coronary artery disease 11 and cancer 12,13 . Since 2009, a few studies on the health of pesticide retailers have suggested that exposure to active pesticide ingredients may induce different adverse health effects in this working community.…”

Background: Recently concern has been raised regarding possible health effects resulting from exposure of a group of pesticide retailers to chemicals they handle. Objective: To investigate the prevalence of respiratory and dermal symptoms, as well as biomarkers of oxidative stress, among pesticide retailers and to compare them with those of an unexposed comparison group. Methods: 70 male pesticide retailers and 64 male construction workers (served as the comparison group) were investigated. Blood samples were taken from all participants to assess the biomarkers of oxidative stress. A data sheet and the European Community Respiratory Health Survey II questionnaire were used to determine the prevalence of dermal and respiratory disorders, respectively. Results: After adjusting for age, weight, height, education level, job tenure, average daily work, presence of family history of respiratory diseases, marital status, smoking status, and number of cigarettes smoked per day, we found that wheezing (OR 4.07, 95% CI 1.17 to 14.17), cough (OR 3.38, 95% CI 1.15 to 9.98), and mucus hypersecretion (OR 3.66, 95% CI 1.45 to 9.05) were significantly more prevalent among pesticide retailers compared with the comparison group. The prevalence of tingling and dryness of skin exposed individuals was significantly higher than unexposed participants. The mean serum concentrations of glutathione and malondialdehyde in the exposed group were significantly higher than those in the comparison group. Conclusion: Occupational exposure to low doses of a mixture of pesticides by retailers was associated with increased prevalence of dermal and respiratory symptoms as well as raised concentrations of biomarkers of oxidative stress.

“…Some studies have shown that occupational exposure to contaminants released during asphalt paving can cause irritative symptoms in the eyes and upper airways ( Raulf-Heimsoth et al , 2007 ). Additionally, several studies have shown that asphalt pavers exhibit reduced lung function and increased mortality due to obstructive lung diseases ( Burstyn et al , 2003 ; Ulvestad et al , 2007 ; Neghab et al , 2015 ; Ulvestad et al , 2017 ). An increased risk of lung and bladder cancer as well as heart diseases has also been reported ( Boffetta et al , 2003 ; Randem et al , 2004 ; Burstyn et al , 2005 ; Burstyn et al , 2007 ; Olsson et al , 2010 ; Mundt et al , 2018 ).…”

Objectives Several studies have demonstrated an increased risk of adverse health effects, including reduced lung function and lung cancer among asphalt pavers, which has been related to occupational exposure to contaminants during asphalt paving. Consequently, occupational exposure among asphalt pavers must be reduced. The aim of this study was to compare the impact of hot mix asphalt (HMA) and warm mix asphalt (WMA) paving on occupational exposure levels during road paving in field experiments. Asphalt temperatures when paving with WMA are usually lower than when paving with HMA due to differences in the asphalt’s composition and method of application. Methods On 11 different road sections, one lane was paved with WMA and one with HMA during the same work shift under approximately identical weather conditions. The weather conditions and asphalt surface temperature were monitored during paving. Fifty-seven samples of fumes and vapor, organic and elemental carbon, amines, and respirable, thoracic, and inhalable particulate matter (PM) fractions were collected by stationary sampling. In addition, 30 samples of fumes and vapor were collected by personal sampling Results Compared to paving with HMA, paving with WMA significantly (P < 0.05; paired Student’s t-test) reduced the geometric mean (GM) air concentration of asphalt vapor (0.04 versus 0.08 p.p.m.), organic carbon (OC; 0.09 versus 0.18 mg m−3), and respirable PM (0.12 versus 0.22 mg m−3). Additionally, the air concentration of OC correlated strongly with the respirable fraction of PM (Pearson’s correlation coefficient 0.83). Conclusions Measured airborne concentrations of respirable PM, OC, and asphalt vapor were lower when paving with WMA than with HMA. Because exposure to airborne contaminants generated during asphalt paving is believed to be responsible for the adverse health effects observed among asphalt pavers, paving with WMA rather than HMA may have health benefits.
