A survey of cancer mortality from 1950 to 1969 was conducted in U.S. counties where the petroleum industry is most heavily concentrated. Male residents of these counties experienced significantly higher rates for cancers of the lung, the nasal cavity and sinuses, and the skin (including malignant melanoma) compared to male residents of counties with similar demographic characteristics. Further study is needed to determine whether these patterns result from exposure to chemical carcinogens, including polycyclic hydrocarbons, involved in the manufacturing of petroleum.
对美国石油工业最为集中的县进行了一项1950年至1969年癌症死亡率的调查。与具有相似人口特征县的男性居民相比，这些县的男性居民患肺癌、鼻腔和鼻窦癌以及皮肤癌（包括恶性黑色素瘤）的比率显著更高。需要进一步研究以确定这些模式是否源于接触石油制造过程中涉及的化学致癌物，包括多环烃。
