Mortality data (183,064 deaths in a 30-year period, 1940-1969) by sex and three ethnic groups (white excluding Spanish-surnamed, nonwhite, and Spanish-surnamed) in 15 regions within the city (Houston), grouped around the air pollution sample collection stations have been analyzed. Valid contrast studies were possible in only one region within the city for all three groups and in six regions for white excluding Spanish-surnamed and nonwhite. There is evidence that the environmental factors of exposure over time to air and industrial pollutants in Houston has had a demonstrable effect in increasing regional mortality from cancer of the respiratory tract as well as from all other diseases and conditions of the respiratory tract and heart disease. This study points out the need for mutually sustained collaboration of effort of the scientific and industrial communities to redirect their attention and research efforts to the exploration of the carcinogenic potential of the microchemical environment.
已对休斯顿市15个区域按性别和三个种族群体（不包括西班牙裔的白人、非白人、西班牙裔）划分的死亡率数据（1940年至1969年30年间有183,064例死亡）进行了分析，这些区域围绕空气污染样本采集站划分。对于所有三个群体，仅在该市的一个区域以及对于不包括西班牙裔的白人和非白人在六个区域进行了有效的对比研究。有证据表明，休斯顿长期暴露于空气和工业污染物的环境因素对增加呼吸道癌症以及所有其他呼吸道疾病和心脏病的区域死亡率产生了明显影响。这项研究指出，科学界和工业界需要相互持续协作，将注意力和研究工作重新转向探索微化学环境的致癌潜力。
