“…Regarding the comparison of the present data with those of foreign workers, we came to the same conclusion as in our previous study (Chatterjee et al 1988), namely that much lower values were obtained in our subjects compared to Americans (Morris et al 1971, Schmidt et al 1973, Higgins and Keller 1973, Jordanians (Sliman et al 1981) and Europeans (Lawther, Brook and Waller 1978). With greater economic status, and consequently higher nutritional standards, and more active outdoor habits, there is improved growth of the musculo-skeletal system of the thoracic cage and lung tissue, resulting in better lung function than our Indian subjects, even when standardized for differences in age and height.…”

“…A close scrutiny of the different studies reveals that in most cases the age groups were restricted to 15-40 years only. We have reported on the standard norms for healthy non-smoking adult men and the present report is complementary to our previous work (Chatterjee, Saha and Chatterjee 1988). The objectives of the present study were, therefore, to establish ventilatory norms for healthy adult non-smoking women over the age range 20-59 years.…”

Pulmonary function measurements were made in 230 healthy non-smoking women from Calcutta with an age range of 20-59 years. The tests consisted of vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in one second as a percentage of forced vital capacity (FEV1%), forced expiratory time (FET), maximum voluntary ventilation, uncontrolled frequency (MVVF), forced expiratory flow (FEF200-1200ml), forced mid-expiratory flow (FEF25-75%), forced end-expiratory flow (FEF75-80%) and peak expiratory flow rate (PEFR). Except for PEFR, all the measurements were made with the help of two 9-litre closed-circuit-type expirographs using standard spirometric techniques. PEFR was recorded with the help of two Wright peak flow meters. Prediction formulae were derived on the basis of physical characteristics. Age and height were found to be the significant predictor variables for VC, FVC and FEV1, while only age was significant for FEV1%. The FVC and FEV1 values of the subjects, standardized for age and height, are much lower than those of Americans, Europeans and Jordanians. On comparison with data reported from other parts of India, it was revealed that the VC and FEV1 values of the current study, after adjustment for age and height, were much higher than those of Southern Indians but comparable with those of North-Western Indians.

“…Pulmonary function test values were predicted from the standard prediction equation of the Kolkata normal subjects 18) . The criteria followed for categorization of the severity of restrictive impairment are based upon the ratios between predicted and observed values of VC and obstructive impairment based on observed values of FEV 1 % 19) .…”

Exposure to Varying Concentration of Fungal Spores in Grain Storage Godowns and its Effect on the Respiratory Function Status among the Workers

et al. 2007

Grain storage depot workers suffer from different respiratory problems after getting the exposure to storage grain dust. Which is a mixture of pesticides, fungi, silica, bacteria, spores, storage mites, animal hairs, pollens etc. The present study was under taken to evaluate the fungal spore concentration in summer and winter season as well as the pulmonary function status of the workers; studies are limited in our country. In summer and winter seasons, air sampling was done to measure the airborne fungal spore concentration inside the godowns by Rotorod sampler, UK. Aspergilla, Alternaria, Drechslera, Epicoccum, Nigrospora, Periconia were very much common and found higher in winter compared to summer. The respiratory functional status was assessed in two groups of workers of the same storage grain depot (total n=316) in summer (n=136) and in winter (n=180). List of the workers was collected from the authority and randomly selected every alternate worker and divide them for the studies in summer and winter seasons. Slow Vital Capacity (SVC), Forced Vital Capacity (FVC), and Peak Expiratory Flow Rate (PEFR) were recorded and Forced Expiratory Volume in one second (FEV 1 ), FEV 1 % and different flow rates were calculated. The Immunoglobulin-E (IgE) level in the blood serum was assessed on post shift pulmonary function tests (PFT) decreased workers. The age, height and weight of the same categories of workers of both studies are highly comparable. Mean PFT values in summer found higher than winter. A gradual decrement of values were found as age was increased but not with duration of exposure. Post-shift PFT was carried in 21.8% (69) workers of which 46.4% (32) workers showed the decrement of values. The serum IgE level of the post-shift PFT decreased subjects was found more than 250 IU/ ml in 53.1% (17) workers. Restrictive, obstructive and combined types of respiratory impairments were noticed among the workers. Presence of different spores in varying concentration in the working atmosphere may be responsible for the post shift decrement of PFT, allergic symptoms, high IgE level and respiratory impairments among the workers.

Background: Several risk factors are associated with cardiopulmonary stress of industrial workers. Most important factors are job strain, job demand, physical effort, work station environment etc. In India, study on occupational cardiopulmonary stress among china clay miners is scanty. Objectives: The present study was aimed to evaluate the cardiopulmonary stresses of the china clay mine workers. Methods: The investigation was carried out on male workers from different china clay mines in the Birbhum district, West Bengal. The cardiovascular stress was evaluated by noting pulse rate of the subjects both during rest and during performance of different types of mine tasks. The cardiovascular stress index (CSI) was evaluated in different mine task. The work rest cycle of different china clay mine tasks was analyzed by video-photographic method. Different pulmonary function parameters, viz, FVC, FEV1, FER and PEF were measured by a digital spirometer to assess the severity of Chronic Obstructive Pulmonary Disease (COPD). Results: The results showed that the working pulse rate and CSI vary with different mine task. It was highest in subjects carrying china clay by head mode. The magnitude of CSI was found to vary with the change of work time and the rest time among the workers. Pulmonary function parameters of china clay mine workers were significantly lower (P<0.01) than other industrial workers. About 79% of total population was suffering from different grades of COPD. Among them, 12% were suffering from severe COPD and 60% from moderate COPD. The higher prevalence of COPD among china clay mine workers might be due to exposure of china clay dust in the work place. Conclusion: It was concluded that the china clay mine workers were suffering from high degree of physiological stress while performing different mine tasks.DOI: http://dx.doi.org/10.3126/ijosh.v2i2.6594 International Journal of Occupational Safety and Health, Vol 2.
