Railways depot in a workplace situation of diesel exhaust particulate pollution survey
%,[link widoczny dla zalogowanych], 91%. Measured dispersion further found,[link widoczny dla zalogowanych], DEP particle size <5 grain quality, damage to the lungs play a decisive role. can be inhaled DEP concentration, dispersion measurements show that, DEP size of a small, easy to enter the body through the respiratory tract, thereby further increasing the health risks of workers exposed. The determination of the sampling for the spring season, by running, wind speed and other factors, so that the measured lower concentrations of DEP. The survey found that in winter the temperature is low locomotive started a long time (even through the night started), the operating environment, poor ventilation and other reasons, workplaces were significantly higher DEP concentrations, among which the old library, particularly parking. To fully understand the workplace depot DEP concentration levels, the future still in different seasons and different sampling conditions for further monitoring. a long time, About DEP can cause cancer, has conducted extensive research at home and abroad, in 1986 NIOSH (National Institute for Occupational Safety and Health Institute) summarizes the information about occupational hazards DEP that DEP should be viewed as a potential carcinogen 1; OSHA (U.S. Department of Labor Occupational Safety and Health Administration) can be developed to allow smoking human dust exposure limit (PEL) for the 5rng / m ', that the DEP to respirable dust in the main, the allowed exposure limits also apply to the diesel engine workplace J. China has not yet developed the highest DEP exposure limits, to protect the health of workers exposed to diesel engines, it is necessary for China's national conditions as soon as possible to work out the maximum allowable concentration of DEP.
