Abstract
Epidemiological studies (1-4) continue to show that fine particulate (PM) air pollution increases the risk for morbidity and mortality from cardiopulmonary diseases. Exposure to [PM.sub.2.5] is believed to induce hypercoagulability, [...]
Objectives: To assess cardiopulmonary morbidity associated with daily exposures to [PM.sub.2.5] in Western Coast of Saudi Arabia. Methods: We monitored 24-h [PM.sub.2.5] and its constituents including black carbon (BC), particulate sulfate p-S[O.sub.4.sup.2-]), nitrate p-N[O.sub.3.sup.-]), ammonium (p-N[H.sub.4.sup.+]) and trace elements (TEs) at a site in Rabigh, Saudi Arabia from May to June 2013 with simultaneous collection of hospital data (N=2513). Cardiopulmonary morbidity risk was determined in a generalized linear time-series model. Results: Exposure to [PM.sub.2.5] was associated with a 7.6% p=0.056) increase in risk of respiratory disease (RD) in females. Black carbon increased RD morbidity risk by 68.1% p=0.056) in females. Exposure to p-S[O.sub.4.sup.2-] increased the cardiovascular disease (CVD) risk by up to 5.3% (p=0.048) in males; and RD by 2.9% p=0.037) in females and 2.5% p=0.022) in males. The p-N[H.sub.4.sup.+] increased CVD risk by up to 20.3% p=0.033) in males; and RD by 10.7% (p=0.014) in females and 8% p=0.031) in males. No statistically significant association was observed for p-N[O.sub.3.sup.-] and TEs exposure. Conclusion: Overall, results show an increased risk for cardiopulmonary morbidity following exposure to air pollution. doi: 10.15537/smj.2017.9.18545
