 | | While the dust levels and lung cancer relative risks were much higher in the two latter refineries, all dose-response relationships appear linear, and the tumor type and sites are the same, indicating that the functional relationship spans a broad range of nickel exposures. |
 | | Data sets from nickel refineries in Huntington, WV (Enterline and Marsh, 1982), Copper Cliff, Ontario (Chovil et al., 1981), Clydach, Wales (Peto et al., 1984), and Kristiansand, Norway (Magnus et al., 1982) provide information available for choice of model or for separation of risk by the type of nickel exposure. |
 | | The dose-response curves for nasal cancer were not used for risk estimation because nasal cancer risk from nickel is thought to be an occupational hazard associated only with the pyrometallurgical process, and these tumors are not found in the general public to the same extent as lung tumors. |
