    Occupational exposure to arsenic has been associated with cancer of the lung, but epidemiological studies of cancer of the lung and environmental exposure to arsenic have produced conflicting results. Case-control studies about point sources of pollution have been useful in identifying environmental hazards. This technique was used to evaluate the risk for lung cancer near a smelter in El Paso, Texas, that uses an arsenic-containing ore and has been in continuous operation since 1887. A comparison of 575 cases of lung cancer with 1490 breast and prostate controls collected from 1944 to 1973 found no significant associations with distance using 2-km concentric circles out to 20 km from the smelter.
