EFFECTS OF DIESEL EXHAUST GAS ON THE HEALTH OF WORKERS. PART I: ENVIRONMENTAL SURVEY

DIIZERUKAIKI GASU GA SHINTAI NI OYOBOSU EIKYC. DAIPPO KANKYCCHOSA

Exhaust gases from diesel locomotives were investigated at location most likely for pulmonary effects on railroad workers to be prominent, namely, in tunnels and service depot structures. The compounds to be determined were carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, methane, aldehydes, and other smoke constitutents. Measurements were conducted with collection bottles, automatic continuous monitoring devices, and alkali filters, while the analyses performed were the saltzman, p-rosaniline, and barium chloranil methods. The pertinent data on nitrogen oxides, methane, and sulfur dioxide are tabulated for diesel as well as other types of locomotives. Results show that in general the gases are low in concentration, although high instantaneously, and are not immediately harmful. There were cases, however, when the concentrations were higher than the levels causing problems in Japan and other Countries. In Tsuchikura Tunnel, especially, the passage of diesel locomotives yielded substantially higher levels of nitrogen oxides.
