Issue Date: | 2019 | Source: | International Journal of Environmental Research and Public Health, 16(13) (Art N° 2284) | Abstract: | Exposure to ambient NO2 and benzene, toluene ethyl-benzene and m+p- and o-xylenes (BTEX) is associated with adverse cardiovascular effects, but limited information is available on the effects of personal exposure to these compounds in South African populations. This 6-month follow-up study aims to determine 7-day personal ambient NO2 and BTEX exposure levels via compact passive diffusion samplers in female participants from Cape Town, and investigate whether exposure levels are associated with cardiovascular risk markers. Overall, the measured air pollutant exposure levels were lower compared to international standards. NO2 was positively associated with systolic and diastolic blood pressure (SBP and DBP), and inversely associated with the central retinal venular equivalent (CRVE) and mean baseline brachial artery diameter. o-xylene was associated with DBP and benzene was strongly associated with carotid intima media thickness (cIMT). Our findings showed that personal air pollution exposure, even at relatively low levels, was associated with several markers of cardiovascular risk in women residing in the Cape Town region. | Notes: | De Boever, P (reprint author), Flemish Inst Technol Res VITO, Hlth Unit, B-2400 Mol, Belgium, Hasselt Univ, Ctr Environm Sci, B-3590 Diepenbeek, Belgium. patrick.deboever@vito.be | Keywords: | air pollution; nitrogen dioxide; BTEX; cardiovascular risk; South Africa | Document URI: | http://hdl.handle.net/1942/28594 | ISSN: | 1661-7827 | e-ISSN: | 1660-4601 | DOI: | 10.3390/ijerph16132284 | ISI #: | 000477037900033 | Rights: | 2019 by the authors.
