The readings of the natural wet-bulb (tnwb) and globe thermometer for computing Twbg index (indoors) were taken between 08.00 to 17.00 h at two-hour intervals in different work locations in the glass bangle and brassware industries. For assessing the physiological reliability of the Twbg index for heat stress, the radial pulse rate was monitored at two-hour(More)
Pulmonary function studies were conducted on 489 pesticide workers engaged in spraying operations on mango plantations. These workers were exposed to a variety of organochlorine and organophosphorus pesticides. A reference group consisting of 208 controls, belonging to the same socioeconomic stratum, was taken from the same area for purposes of comparison.(More)
In a cross-sectional study, a random sample of 197 male workers drawn from different sections of 10 leather tanneries in Kanpur were selected for the assessment of health risks. A control group comprising of 117 male subjects belonging to a similar age group and socioeconomic strata, who never had any occupational exposure in the leather tanneries, were(More)
A group of manual welders (N = 57) engaged in gas welding joint faces of moulded brasswares, age group 13-60 years (mean: 29.2 +/- 1.37 years), having a mean exposure period of 12.4 +/- 1.12 years (range: 1-35 years) were subjected to spirometry to evaluate the prevalence of spirometric abnormalities. The findings were compared with those obtained from a(More)
Oxidative stress status and Acetylcholinesterase (AChE) activity were studied in blood samples obtained from 61 agricultural workers engaged in spraying organophosphorus (OP) insecticides in the mango plantation, with a minimum work history of one year, in the age range of 12-55 years. Controls were age-matched, unexposed workers, who never had any exposure(More)
A stratified random sample of 580 workers aged between 18 and 50 years representing each sub-occupation in the brassware industry was studied for the prevalence of chronic bronchitis in relation to occupational and environmental factors. The findings were compared with those obtained in a reference group (N = 131) belonging to similar socio-economic status(More)
The Comet assay has found wide acceptance in monitoring human genotoxicity caused by lifestyle and occupational and environmental factors. In the present study, we have used the Comet assay to measure the DNA damage in a population of rural Indian women cooking with biomass fuels (BMFs; fire wood and cow dung cakes). Out of 144 volunteers, 70 used BMFs for(More)
A multiple regression model considering dependent variables like vital capacity (VC), forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR) and age and height as independent variables for the adult male population, which includes whites of European descent and non-whites was reviewed to evaluate the role of lung function status(More)
This study is aimed at evaluating the association between occupational exposure to organophosphate (OP) and carbamate (CB) pesticides and semen quality as well as levels of reproductive and thyroid hormones of pesticide sprayers in Malihabad, Lucknow, Uttar Pradesh, India. Thirty-five healthy men (unexposed group) and 64 male pesticide sprayers (exposed(More)
