Although most people are thought to receive their highest acute exposures to gasoline while refueling, relatively little is actually known about personal, nonoccupational exposures to gasoline during refueling activities. This study was designed to measure exposures associated with the use of an oxygenated fuel under cold conditions in Fairbanks, Alaska. We compared concentrations of gasoline c...

v PREFACE Ever since the dawn of civilization, it has been man's dream and wish to fly. This dream became reality when the Wright brothers first took to the sky. To be able to humbly contribute to further technological advancement of the aerospace industry is a dream come true. Due to the increasingly more aggressive competition in the aviation industry, many new concepts were developed. One of...

Although automobile refueling represents the major source of benzene exposure among the nonsmoking public, few data are available regarding such exposures and the associated uptake of benzene. We repeatedly measured benzene exposure and uptake (via benzene in exhaled breath) among 39 self-service customers using self-administered monitoring, a technique rarely used to obtain measurements from t...
