this study was carried out to evaluate tobacco dust concentration and also designing a suitable ventilation system for reduction of tobacco dust concentration in a tobacco processing factory in the north of iran.gravimetric method was used to determine the tobacco dust concentrations in the emission sources an also indoor workplace. a local exhaust ventilation system was designed according to t...

The ventilatory capacities of 195 tobacco factory workers exposed to tobacco dust and 190 Libyan men not exposed to tobacco dust were measured. In both groups, the forced vital capacity (FVC) and forced expiratory volume in 1 s were found to be correlated with age, stature, sitting height and body surface area. Those exposed to tobacco dust have decreased ventilatory capacity values as compared...

OBJECTIVES The aim of this study was to examine the pollution level of the occupational environment and to investigate the effects of occupational exposure to tobacco dust on the respiratory system of tobacco workers. No such study has previously been conducted in Greece, which is one of the main tobacco-producing countries. METHODS A total of 1,020 seasonal and permanent tobacco workers (188...

INTRODUCTION Some car rental companies in California and other states in the USA have established non-smoking policies for their vehicles. This study examined the effectiveness of these policies in maintaining smoke-free rental cars. METHODS A stratified random sample of 250 cars (non-smoker, smoker and unknown designation) was examined in San Diego County, California, USA. Dust, surfaces and...

Small airways offer 1/4th of the total airways resistance. Disease of small airways results from exposure to tobacco smoke, mineral dust, air-pollutants, and viral infections. It may also be associated with connective tissue disorders or may follow bone marrow, lung, or heart-lung transplantation. The pulmonary function tests are deranged late in the disease and the damage done is irreversible....

The effects of exposure to gold mining dust with a high concentration of free silica and tobacco smoking on mortality from lung cancer was assessed in a sample of 2209 white South African gold miners who started mining exposure during 1936-43, and were selected for a study of respiratory disorders in 1968-71 when they were aged 45-54. The mortality follow up was from 1968-71 to 30 December 1986...

Background and Purpose: The aim of this pilot study was to determine possible genotoxic effects of occupational exposure to tobacco dust between workers employed in tobbaco industry and non-exposed population. Subjects and Method: The exposed group consisted of 20 subjects with mena age of 43.4 years. The average duration of their occupational exposure was 19.95 years. The control group consist...

Tobacco dust represents a critical threat to the operators’ respiratory health. Even when wet scrubbers display high purification efficiencies and strong adaptability dust, their potential applications in tobacco industry have not been studied. In present research, removal efficiency of scrubber for fine were examined at laboratory industrial level. Results showed that under conditions reached ...

Background: The baking industry is not a very hazardous occupational environment, but it is not free from ergonomic derangement. The biscuit factory workers are exposed to noise, heat, odour, flour dust, sugar dust and biscuit dust. Method: A cross sectional study was conducted in all males and females of more than 18 years among employees of a biscuit company in Puducherry who met the inclusi...

Exposure to indoor air pollutants such as tobacco smoke and dust mites may exacerbate childhood asthma. Environmental interventions to reduce exposures to these pollutants can help prevent exacerbations of the disease. Among the most important interventions is the elimination of environmental tobacco smoke from the environments of children with asthma. However, the effectiveness of reducing ast...
