In many occupational settings, the ambient environment is a sink of various contaminants that emerge from point and nonpoint sources and causes direct exposure to workers. Such exposures in petroleum-related occupations usually result from routine transportation, distribution, accidental spills, improper handling and use, and leaching of petroleum hydrocarbons products; Apart from direct occupational exposure, nonoccupational population around chemical factories and other occupational sites may also undergo indirect exposure. Thus, occupational exposure hematotoxicity and other blood disorders such as blood cancer (leukemia), aplastic anemia, and dysplastic bone marrow conditions are
In developing countries such as Pakistan, creating awareness among workers about workplace chemicals and other related hazards should also be given priority. This study was planned to evaluate the effects of continuous exposure to solvents, chemical contaminants, and other confounding factors that may cause functional changes in blood parameters. It may be helpful in future for suggesting the most significant priorities in the light of research outcomes, to minimize workplace- and occupation-related health risks, and to ensure safety to workers’ health.
