“…Forty percent of research into occupational risk factors in the sampled literature investigated exposure to contaminants, which was associated with the aforementioned concern over dietary exposure to heavy metal contaminants, as well as other sources, for example, fuel exhaust (Moitra, Maity, Haldar, Pandit, & Sahu, ). This was followed by research into the impacts of work and sleep patterns (13%) and exposure to climatic conditions (11%).…”

Health in fishing communities: A global perspective

In resource‐dependent communities such as fishing communities, human health underpins the ability of individuals and families to maintain viable livelihoods. Fishing is a dangerous occupation, in which fishers are exposed to health risks both on and offshore. Many of these risks and associated health concerns also extend to fishing families and wider communities. Despite the importance of health, there is a lack of understanding of the breadth of health issues affecting people associated with fishing. This study presents the findings of a scoping review of peer‐reviewed literature that identifies the range of health issues and health determinants studied in fishing communities around the world. The findings reveal a wide variety of documented health issues, but with greater emphasis on physical health and occupational and behavioral factors, with limited attention paid to mental health. The majority of studies focused on fishers themselves, as opposed to other subgroups within fishing communities. Geographic differences in the health topics investigated highlight prevalent concerns and offer potential to share insights and solutions across contexts. The breadth of findings illustrates the complexity of health for people dependent on fishing, and the relevance of the many health determinants in maintaining viable fishing communities. We propose that a social well‐being approach offers an integrative lens through which a better understanding of human health in fisheries can be achieved and used to inform fisheries management that is ecologically and socially sustainable.

“…These conditions include obstructive lung diseases, like asthma, methacholine airway responsiveness, ambient ozone, torquetenovirus, anthracofibrosis, trawler fuel exhaust, ataxiatelangiectasia (AT), left ventricular hypertrophy in patients with morbid obesity, and BMI. [33][34][35][36][37][38][39][40][41] The relationship between this ratio and restrictive lung disease has not been directly studied in previous studies.…”

Introduction and objective: The role of spirometry in the diagnosis of restrictive lung diseases is unclear. This study investigated the sensitivity and specificity of the forced expiratory flow 25–75 (FEF25–75)/forced vital capacity (FVC) parameter in diagnosing restrictive lung disease. Methods: In this study, the records of all restrictive patients who were referred to the pulmonary centre of Imam Khomeini Hospital, Tehran, Iran, from March 2021–March 2022 have been reviewed, and the indexes in the body box and spirometry have been recorded. Results: A total of 527 people were included in the study. Among them, 134 people (25.4%) had restrictive lung disease. The average area under the graph of the FEF25–75/FVC index is 0.648±0.028. It can be said that the area under the graph for the FEF25–75/FVC index is between 0.594–0.703. The FEF25–75/FVC index at values above 79.90 has a sensitivity of 70.9% and a false positive rate (1- specificity) of 53.2%. Conclusions: According to the result of this study, the ratio of FEF25–75/FVC index in spirometry at above 79.90 has a sensitivity of 70.9% and a false positive rate (1- specificity) of 53.2%. Therefore, it can be used as a screening test for restrictive lung diseases.

“…Respiratory symptoms were recorded using a previously used English-back Bengali-translated version of the European Community Respiratory Health Survey (ECRHS-II) questionnaire containing items on respiratory health, occupational exposure (in terms of total work experience in the sector) and lifestyle factors such as smoking habits (Moitra et al, 2013(Moitra et al, , 2014a(Moitra et al, , 2015b(Moitra et al, , 2016. Subjective respiratory complaints in the previous 12 months included: (a) acute/current or chronic/prolonged cough; (b) production of phlegm; (c) acute or chronic wheezing or whistling of the chest; and (d) breathing trouble.…”

Background: Despite the available clinico-epidemiological evidence of heavy metal-associated respiratory health hazards among metal arc-welders, experimental confirmation of such an association is lacking. Methods: In this study, we recruited 15 metal arc-welders and 10 referent workers without direct exposure. We assessed respiratory health through a questionnaire and spirometry; estimated manganese, nickel and cadmium levels in blood, urine and induced sputum; performed differential counts of sputum leucocytes and measured plasma malondialdehyde (MDA). We used atomic force and scanning electron microscopy to assess the physical property of the alveolar macrophages (AMs) obtained from induced sputum and analysed cell surface deposition of heavy metals using energy dispersion X-ray analysis (EDX). Sputum cellular DNA damage was assessed by DNA-laddering assay. Results: There was a higher body burden of manganese and nickel in the metal arc-welders than the referents. Among major spirometric indices, only the forced mid-expiratory flow rates (FEF 25-75) were reduced in the welders compared with the referents (63.4 + 14.7 vs. 89.2 + 26.7, p < 0.01); this reduction was associated with both heavy metal levels (: À41.8, 95% CI: À78.5% to À5.1%) and plasma MDA (À0.37; À0.68 to À0.06). In metal arc-welders, significant physical and morphological changes were observed in AMs through microscopic evaluation while EDX analyses demonstrated higher deposition of heavy metals on the AM cell surface than the referents. We also observed a higher degree of DNA damage in the sputum cells of the exposed workers than the referents. Conclusion: Heavy metal exposure-induced adverse respiratory effects among metal arc-welders are mediated through haematological and cytological interactions.
