RESUMO
Mutual communication requires a media and printing is one of the effective and easily diffusible media for communication. During the last few years, revolutionary changes have taken place in communication technology. It is essential for the expansion and development of education and for dissemination of all theories, ideas, inventions and discoveries of mankind. To evaluate the occupational health hazards associated with inks used in printing processes at Jang Group of Newspapers, Lahore. This cross sectional study was conducted on 50 workers who were directly in the use of ink during the period from 1999 to 2000. The concentrations of various chemical are estimated with the help of absorption and adsorption of the air pump by personal sampler and high volume air samples. The air is sucked through glass fiber filter and a column of 10 ml of carbon tetra chloride in a hubble bubble tube. Time of exposure is 0-5 years and in most of the cases the forced expiratory volume in one second is 70% + 5 but peak expiratory flow rate is markedly decreased which shows that lung functions are deteriorated to a considerable extent. As the time of exposure increases that is from 6 to 10 years, 11-15 years and 16-20 years, the lung functions steadily decreases by the increase in the time of exposure and extent of deteriorating in lung functions
