A significant relationship between exposure to cadmium and PAHs from urban air pollution and blood pressure has already been found. The aim of the study is to evaluate if other urban pollutants maintain a similar relationship in outdoor workers.
349 subjects of both sexes were enrolled in the study; we evaluated values of environmental and biological monitoring of respirable dust, arsenic, lead, benzene, toluene, xylene and we measured blood pressure (BP) in upright and in supine position; to analyze data we used multiple linear regression. Also we valued our results in the light of those we have obtained in previous research.
Multiple linear regression showed no significant results that demonstrate a relationship between BP and these pollutants.
The results of our study lead to assume that exposure to urban pollutants studied has not connection with blood pressure, and to retain valid the relationship previously observed for cadmium and PAHs, which seem to be the only pollutants that can affect blood pressure.
业已发现，城市空气污染中的镉和多环芳烃暴露与血压之间存在显著关联。本研究旨在评估其他城市污染物在户外工作者中是否保持类似关系。
本研究招募了349名男女受试者；我们评估了可吸入粉尘、砷、铅、苯、甲苯、二甲苯的环境和生物监测值，并测量了受试者直立位和仰卧位的血压（BP）；我们使用多元线性回归分析数据。此外，我们根据先前研究所得结果对本研究结果进行了评估。
多元线性回归未显示出表明血压与这些污染物之间存在关联的显著结果。
我们的研究结果表明，所研究的城市污染物暴露与血压无关，先前观察到的镉和多环芳烃之间的关系仍然成立，镉和多环芳烃似乎是仅有的可能影响血压的污染物。
