Abstract
Most of the common solvents have a high volatility, thus constituting a potential hazard from the standpoint of inhalation. The industrial uses of organic solvents necessitate precautionary measures to prevent exposure of workers to hazardous atmospheric concentration of volatile materials.
Organic solvents and their vapours are a common part of our environment.
Many industrial workers are exposed to toxic solvents and vapours. Occupational exposure to volatile organic solvents in many industries affect several organs as liver, kidney , respiratory system, hematopoietic system and local irTitation .
Few organIc solvents have specific toxic effect on central and peripheral nervous system. In printing and food packaging industries as well as paint industry, two organs mainly liver, kidney in addition to bone marrow and leucocytes were regarded as the targets oftoxicity. Concentrations of these highly volatile materials from the standpoint of inhalation, ingestion and dennal absorption, by which toxic chemicals can gain entry to the body in repeatedly exposed 8 hours a day and 48 hours a week workers.
The present work was carried on sera of 41 flexographers exposed to a mixture of solvents including isopropyl (IPA) and butyl alcohol (BA) in the print of plastic film of polyethylene (PE) and polypropylene (PP) industry. Their combined effect may be additive, antagonist or potentiating as hepatotoxic or nephrotoxic
