| 摘要： | The goal of the study was to quantify asbestos concentrations downwind of serpentine covered unpaved roads and to relate the concentrations to vehicle traffic, road surface materials, and meteorological and climatological conditions. Data which were obtained at roads in eastern Stanislaus County, California were used to develop a model, the California Serpentine Covered Roadway Asbestos Model (CALSCRAM), for predicting asbestos emissions from serpentine covered unpaved roads. When compared with predictions made by the currently used EPA model, CALSCRAM reduced the EPA model prediction errors an average of 76%. |
