 Abstract

Organic solvents are being used extensively in many industrial processes. Occupational exposures to these solvents are often deleterious to workers. In order to determine stress profiles of exposed workers in the context of organic solvents’ (acetone, glycol ethers, methanol, toluene and xylene) exposure, a questionnaire based survey of screen printing units located in Lahore, Pakistan was conducted. Loss of memory was the key threat found among the workers and the percentage of patients suffering from this disorder reached up to 72%. The ratio of occurrence of this symptom was higher in workers of age between 40 and 50 years. Other common disorders included hypertension, depression, dizziness, dry skin, headaches, occupational fatigue, sore throat and vision difficulty. The percentages of patients suffering from such troubles were 47%, 53%, 56%, 55%, 49%, 56%, 30% and 38%, respectively. The overall trend of disorders increased with increase in age. These results necessitate guidance and strict appliance of proper working stations wherein efficient exhaust system(s) be installed immediately.
