An ecologic study design was used to investigate the relationship between cancer risks and residence in communities adjacent to petrochemical industrial counties (PICs). Directly age-adjusted mortality rates for cancer during 1982-1991 among 16 counties characterized by a heavy concentration of petrochemical industries were compared to rates among 16 matched counties with similar concentration of nonpetrochemical manufacturing industries, urbanization level, and demographic characteristics. An excess rate for liver cancer among males was found in the so-called PICs. The correlation could not be explained by confounding variables such as urbanization, socioeconomic class, or employment in nonpetrochemical industries. No other increased cancer risks were found to be associated with residence near petrochemical industries.
采用生态学研究设计来调查癌症风险与居住在石化工业县（PIC）附近社区之间的关系。将1982 - 1991年期间16个以石化工业高度集中为特征的县的癌症直接年龄调整死亡率，与16个匹配的县（具有类似的非石化制造业集中度、城市化水平和人口特征）的死亡率进行比较。在所谓的PIC中发现男性肝癌发病率过高。这种相关性无法用城市化、社会经济阶层或非石化行业就业等混杂变量来解释。未发现居住在石化工业附近与其他癌症风险增加有关。
