Abstract

A considerable number of workers in the United States are employed in asphalt industries and are potentially exposed to asphalt fumes. The information regarding the potential carcinogenic hazards of such fumes to exposed workers is still limited. Studies have been conducted to determine the cytogenetic effects of roofing asphalt fume using cultured mammalian cells. Exponentially growing Chinese hamster lung fibroblasts (V79 cells) were exposed to different concentrations of condensates of type I and type III roofing asphalt fumes, generated at temperatures similar to actual roofing operation (316 +/- 10 degrees C). The frequencies of micronucleated cells in the treated and control cultures w..
