Ai.borne bi.aerosols and thei. i.pact on human health

Bi.aerosols consi.t of aerosols ori.i.ated bi.logi.ally such as metaboli.es, toxi.s, or fragments of mi.roorgani.ms that are present ubi.ui.ously i. the envi.onment. i.ternati.nal i.terests i. bi.aerosols have i.creased rapi.ly to broaden the pool of knowledge on thei. i.enti.i.ati.n,quanti.i.ati.n, di.tri.uti.n, and health i.pacts（e.g., i.fecti.us and respi.atory di.eases,allergi.s, and cancer）. However, ri.k assessment of bi.aerosols based on conventi.nal culture methods has been hampered further by several factors such as：（1） the complexi.y of mi.roorgani.ms or deri.ati.es to be i.vesti.ated;（2） the purpose, techni.ues, and locati.ns of sampli.g; and（3） the lack of vali. quanti.ati.e cri.eri.（e.g., exposure standards and dose/effect relati.nshi.s）. Although exposure to some mi.robes i. consi.ered to be benefi.i.l for health,more research i. needed to properly assess thei. potenti.l health hazards i.cludi.g i.ter-i.di.i.ual suscepti.i.i.y, i.teracti.ns wi.h non-bi.logi.al agents, and many proven/unproven health effects（e.g., atopy and atopi. di.eases）.
