Health effects in population exposed to air pollution of CO, NOx, elemental carbon (EC) and other particulate matter constituting the main health hazards of diesel exhaust (DE) has been known for years. As to occupational settings, especially in open pit mining operations, air concentrations of these contaminants may well reach the levels significantly exceeding occupational exposure limits (OELs) that in a large number of documented instances could impose the risk of acute poisoning in miners.
From observational and experimental studies carried out by NWPHRC it have been demonstrated that cold environments are capable of changing the behavior and fate of airborne contaminants as well as reducing the efficiency of personal respiratory protection, increasing the duration of working operations and energy expenditures thereby affecting occupational exposures.
The deposition of respirable particles in animal lungs at ambient temperature around 00C was proved to be significantly higher as compared to the same exposure at room temperature.
The cold-induced modification of exposure and related health effects caused by diesel exhaust is to be further evaluated in an epidemiologic study planned in the framework of MineHealth project.
