The amounts (microgram m-2) and concentrations (microgram g-1) of cadmium, copper, lead and zinc have been measured in house dust in Christchurch, New Zealand. For 120 houses surveyed the geometric mean concentrations of the four metals are 4.24 micrograms g-1, 165 micrograms g-1, 573 micrograms g-1 and 10,400 micrograms g-1, respectively. In addition eleven variables, such as house age, carpet wear and traffic density, were recorded for each property and the results analysed with respect to their effects on the amounts and concentrations of the four elements. The amounts of all the metals were highly correlated with the overall dustiness of the houses, which was found to be predominantly determined by the degree of carpet wear. No one dominant source of cadmium was identified, although several minor sources including carpet wear, galvanized iron roofs and red/orange/yellow coloured carpets were implicated. Petrol lead and lead-based paints were identified as significant sources of lead in house dust. Rubber carpet underlays or backings were identified as a significant source of zinc, with some contribution from galvanized iron roofs. Road traffic and probably the existence of a fire place appear to contribute to the copper levels.
已对新西兰克赖斯特彻奇市室内灰尘中的镉、铜、铅和锌含量（微克/平方米）及浓度（微克/克）进行了测量。在接受调查的120所房屋中，这四种金属的几何平均浓度分别为4.24微克/克、165微克/克、573微克/克和10400微克/克。此外，还记录了每处房产的11个变量，如房屋房龄、地毯磨损程度和交通密度，并分析了这些变量对四种元素含量和浓度的影响。所有金属的含量都与房屋的整体灰尘程度高度相关，而房屋的整体灰尘程度主要由地毯磨损程度决定。尽管包括地毯磨损、镀锌铁屋顶和红色/橙色/黄色地毯在内的几个次要来源与镉有关，但未确定镉的主要来源。汽油中的铅和含铅涂料被确定为室内灰尘中铅的重要来源。橡胶地毯衬垫或背衬被确定为锌的重要来源，镀锌铁屋顶也有一定贡献。道路交通以及可能存在的壁炉似乎导致了铜含量升高。
