ABSTRACT: Adverse
health and environmental effects of household dust are derived from their
chemical composition and properties. In this study, household, stairs and
entryway dust (, , Cl-,, Na+, K+,
Ca2+ and Mg2+ in the household and entryway dust was
found in urban area. was abundant in household, entryway and stairs
dust followed by Cl- and . Its average
concentrations were 21.38, 14.57 and 15.83 mg/g, respectively. The
household/entryway (I/O) concentration ratios of measured ion components indicate
that these species might derive from indoor sources, although outdoor sources
could be present as well. pH values of household, stairs and entryway dust
ranged from 6.43 to 8.53, indicating that these dusts brought a large amount of
crustal species, and might alleviate the tendency of acidification. The
relationships between the concentrations of acidic components ( and ) and basic
components (, Ca2+ and
Mg2+) in household, stairs and entryway dust confirm that the
acidity of dust is neutralized. Ca2+ and in household and stairs dust and Ca2+ and Mg2+ in entryway dust are the most dominant
neutralization substances.
