摘要: Children ingest house settled dust by normal hand to mouth activity. Because contains some metals associated with health hazards, this pathway of exposure is an issue in risk assessment. The concentration thus a matter concern, together their bioaccessibility, that is, the fraction absorbed humans. This review examines articles studying metal content (excluding Pb) household ordinary homes. Relatively few report concentrations and bioaccessibility dust. Ag, As, Al, Au, Ba, Be, Bi, Br, Ca, Cd, Ce, Co, Cr, Cu, Fe, Hf, Hg, I, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Rb, Sb, Sc, Se, Sm, Sn, Sr, Te, Th, Ti, U, V Zn have been studied. Na P are found exceeding 1000 μg.g−1. Bioaccessibility documented still more rarely varies substantially between within (Ag, 60–90 %; 10–90 10–80 50–90 15–50 10–50 20–80 5–45 10 40–60 5–10 10–30 Zn, 80–90 %). It depends on chemical speciation, particle size organic carbon, which play role partitioning among mineral phases digestion process. Digestion conditions: temperature, pH, duration type acid used essential parameters determine measured House-dust metalloids vary throughout home as well homes across seasons locations. has also changed over time due decrease industrial emissions regions evolution automobile ones. Furthermore, soil cannot predict indoor concentrations. difficult or its bioaccessibility. Local measurements therefore for consideration background exposure.
