Abstract: Haze, a serious form of air pollution, is mainly consists of gaseous pollutants and particulate matter. With high physicochemical properties and great harmfulness, particulate matter is the key point of haze. Hypertensive disorders of pregnancy (HDP) is a common clinical disease specially correlated to pregnancy, which had serious harm on maternal and child health. The etiology and pathogenesis mechanism of HDP is not yet entirely clear. The physiological characteristics of pregnant women make them and fetus to be susceptible to pollutants and to increase their exposure to air pollutants. Previous studies confirmed the close relations between HDP and maternal exposure to air pollutants during pregnancy. The pathogenesis might be related with oxidative stress and systemic inflammation. However, those hypothese need more study to validate. In this paper, we discuss the close relations between haze and gestational hypertension and preeclampsia.

Key words: Air pollution, Particulate matter, Hypertension, pregnancy-induced, Haze, Gaseous pollutants
