Effects of occupational heat exposure on female brick workers in West Bengal, India

Background : Manual brick-manufacturing units in India engage a large number of female workers on a daily-wage basis for a period of 8 months per year. There are two groups of female workers in the brickfields: the brick molders and the brick carriers. These brickfields are mostly unorganized, and the workers are exposed to extreme conditions such as very high seasonal heat. The present trend of increasing temperatures, as a result of global warming and climate change, will put an additional burden on them. Objective : This study aims to evaluate the effect of workplace heat exposure on the well-being, physiological load, and productivity of female brickfield workers in India. Design : A questionnaire study (n=120), environmental temperature, and weekly work productivity analyses were evaluated for 8 months in the brickfields. Cardiac strain and walking speed (subset, n=40) were also studied and compared in hotter and colder days amongst the female brickfield workers. Results : The subjects experience summer for about 5 months with additional heat stress radiating from the brick kiln. The weekly productivity data show a linear decline in productivity with increased maximum air temperature above 34.9°C. The cardiac parameters (peak heart rate (HRp), net cardiac cost (NCC), relative cardiac cost (RCC), and recovery heart rates) were significantly higher on hotter days (Wet Bulb Globe Temperature (WBGTout) index: 26.9°C to 30.74°C) than on cooler days (WBGTout index: 16.12°C to 19.37°C) for the brick molders; however, this is not the case for the brick carriers. As the brick carriers adapt to hotter days by decreasing their walking speed, their productivity decreases. Conclusion : We conclude that high heat exposure in brickfields during summer caused physiological strain in both categories of female brickfield workers. A coping strategy employed by the brick carriers was to reduce their walking speed and thus lose part of their earnings. The lost productivity for every degree rise in temperature is about 2% in the brickfields. This reduction will be exacerbated by climate change and may undermine the quality of life of female brickfield workers

Geochemistry of tailings at malanjkhand copper mine, Madhya Pradesh

This study aimed at mineralogically characterizing and finding the metal content of the tailings coming out from the mining of copper at Malanjkhand copper mine, located in north east of Balaghat, Madhya Pradesh which is the largest copper deposit in India producing nearly 2.2 million tonnes of copper tailings annually. The tailings were characterized geochemically by taking samples from the tailing pond. The mineralogy of the samples were studied and the concentrations of copper, lead, zinc, cadmium, manganese and nickel were measured. The tailings mostly consisted of quartz, kaolinite, muscovite, plagioclase, pyrite, chalcopyrite, orthoclase, goethite, chloride and jarosite. Copper, cadmium and lead were above their respective crustal abundance and the concentration of copper was found to be the maximum

SDG 3: Good health and well-being - framing targets to maximise co-benefits for forests and people

Key Points: The achievement of SDG 3 depends on many other SDGs; some SDGs are logically inconsistent, especially in the attempt to increase conventionally defined GDP while preserving natural capital. Any short-term gains for human health from further forest conversion (e.g. food production) creates short- and long-term, direct and indirect health risks for humans, as well as for other biota. Failure to ensure universal access to sexual and reproductive healthcare services (including family planning) will increase pressure on forests at local, regional and global scales. The burning and clearing of forests cause significant harm to health via impaired quality of water, soil and air; increased exposure to infectious diseases and impacts climate regulation. Many infectious diseases are associated with forest disturbances and intrusions; some important infectious diseases have emerged from forests (notably HIV/AIDS). Greater exposure to green space, including forests, provides mental and physical health benefits for the growing global urban population

Animal Welfare Attitudes: Effects of Gender and Diet in University Samples from 22 Countries

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest variance in AWA was explained by diet, followed by country and gender. In terms of diet, 6385 participants reported to be omnivores, 296 as pescatarian, 637 ate a vegetarian diet and 434 were vegans (n = 162 without answer). Diet was related with CRAS-S scores; people with a vegan diet scored higher in AWA than omnivores. Women scored significantly higher on AWA than men. Furthermore, gender differences in AWA increased as gender inequality decreased

Assessment of the lung function status of the goldsmiths working in an unorganized sector of India

Context: Exposure to various types of fumes and gases are very common in Jewelery industries. No Report is available regarding the effects of those fumes and gases on the respiratory functions of the goldsmiths. Due to lack of proper monitoring of the workplace environments in these unorganized sectors, workers get very much affected by the occupational exposures to those irritants. Aims: The present study aimed to investigate whether the occupational exposures to fumes and gases might alter the lung functions of the goldsmiths. Materials and Methods: A total of 118 goldsmiths and 66 unexposed control subjects were taken randomly for the study. The goldsmiths were further classified in 3 groups according to duration (year) of exposures in the work environment, ETA 1 (less than 5 years), ETA 2 (more than 5 years but less than 10 years), and ETA 3 (more than 10 years). Peak expiratory flow rates (PEFR), forced vital capacity (FVC), and forced expiratory flow rates of different intervals (FEF 25% , FEF 50% , FEF 75% , FEF 25-75% ) were measured using computerized Spirometer (Maestros Mediline, India). The statistical analyses were carried out using Minitab software version 3. Results: Lung functions of the goldsmiths significantly (P < 0.01) decreased from that of the control group. Inter-group comparison also showed the deteriorations of lung functions was associated with exposure time, and more exposed workers had significantly less (P < 0.01) efficiencies of lung functions. Conclusions: Workplace fumes and gases were responsible for deterioration of the lung function status of the goldsmiths

An ergonomic study of postural stress of nurses working in orthopedic wards

It was reported high prevalence of musculoskeletal disorders among nurses. Among the wards, personnel working in Orthopedic wards routinely perform activities that require lifting heavy loads in awkward posture. Challenges faced by them assess patients skillfully and uniquely because orthopedic patients typically present with multiple, complex health problems. During orthopedic patient handling work-related postural strain are most common in health care unit personnel. This study aims at evaluating the different work-related musculoskeletal strain due to awkward postures, body parts discomforts, and find out some ergonomic solutions to these problems. Forty nurses working in orthopedic settings of two hospitals were interviewed by modified Nordic Questionnaire to reveal the prevalence of musculoskeletal problems and pain in various regions of the body. BPD Scale was used to identify the intensity of different body parts discomforts. Video recordings and still photographs were taken to evaluate postural stress during different activities were analyzed by OWAS (Ovako working posture analysis) method. Activity analysis chart was also used to represent the duration of different activities of nurses in their respective duty hours. It was observed that the most physically demanding and postural strenuous task is transferring patient alone. In orthopedics wards different activities like assist patient to walk, changing, other care works are strenuous because as about 90% of adult patient are over 50 kg of body weight and due to facture or other problem are unstable. Some ergonomic interventions like assisted lifting, lifting aids, training, etc. are recommended to improve the working conditions and reduce postural strain.
