(一)在體研究:
整體(全身)暴露:被普遍認(rèn)為是最接近模擬人的現(xiàn)實暴露的方式。對PM2.5暴露來說,目前主要有濃縮暴露系統(tǒng)和非濃縮(現(xiàn)實濃度)暴露系統(tǒng)。代表性參考文獻(xiàn)如下:
濃縮系統(tǒng):Xu X, et al. Long-term exposure to ambient fine particulate pollution induces insulin resistance and mitochondrial alteration in adipose tissue. Toxicol Sci. 2011;124(1):88-98
非濃縮系統(tǒng):Xu X, et al. Association of systemic inflammation with marked changes in particulate air pollution in Beijing in 2008. Toxicol Lett. 2012;212(2):147-56
“開放”(Open top)系統(tǒng):Mauad T, et al. Chronic exposure to ambient levels of urban particles affects mouse lung development. Am J Respir Crit Care Med. 2008;178(7):721-8.
罩棚(shed)系統(tǒng):Somers CM, et al. Reduction of particulate air pollution lowers the risk of heritable mutations in mice. Science. 2004;304(5673):1008-10
經(jīng)鼻暴露:多為將顆粒物溶入細(xì)胞培養(yǎng)液中經(jīng)鼻腔暴露,比較“機(jī)械”但仍屬于“經(jīng)氣管”的渠道。代表性參考文獻(xiàn)如下:
Arantes-Costa FM, et al. Effects of residual oil fly ash (ROFA) in mice with chronic allergic pulmonary inflammation. Toxicol Pathol. 2008;36(5):680-6
