“…According to the analysis of the mineral fraction in house (office) dust (Molhave et al 2000), the dominant minerals of natural origin are silicates (apatite, biotite, feldspar, hornblende, quartz, etc.) and other minerals (sea salt, limonite, haematite, etc.).…”

This article presents the impact of the ecological investment in ironworks (dust filter installation) and construction works at a highly contaminated brownfield site on the chemical composition of household dust (HD) and street sediment (SS) in Celje, Slovenia. The evaluation is based on two sampling campaigns: the first was undertaken 1 month before the ecological investment became operational and the second 3 years later. The results show that dust filter installations reduced the content of Co, Cr, Fe, Mn, Mo, W and Zn on average by 58% in HD and by 51% in SS. No reduction was observed at sampling points in the upwind direction from the ironworks. By contrast, the impact of the construction works on the highly contaminated brownfield site was detected by a significant increase (on average by 37%) of elements connected to the brownfield contamination in SS. Such increase was not detected in HD.

“…A number of studies have suggested that there is a possibility that metals in the indoor dust can accumulate in humans, either directly or indirectly by inhalation, ingestion as a result of hand-to mouth activity or via dermal contact absorption (Al-Rahji & Seaward, 1996;Molhave et al, 2000). Young children, especially toddlers, can easily ingest soils or indoor dusts unintentionally since they spend most of their time indoors and much of this time is spent in contact with floors, engaging in mouthing of hands, toys and other objects or the consumption of food contaminated by hands (Mohd Tahir, 2007;Adekola & Dosumu, 2001).…”

Interior floor dust is found to be one of the major pathways of childhood exposure to indoor air pollutants. This study aims to carry out a general survey of heavy metals (Al, Ba, Cr, Cu, Fe, Ni and Pb) contamination at selected nursery school buildings in Shah Alam, Selangor and to study their relationship with the surrounding environment. The samples were collected using a brush and a plastic dust pan, after which the samples were digested using the wet digestion method. The heavy metal concentration was determined by inductively coupled plasma -optical emission spectrometer (ICP-OES). The results show that the heavy metal concentrations at nursery school building were in the range 901. 2 -1510.0, 13.3 -76.7, 12.0 -22.6, 22.2 -42.7, 1489.0 -7919.0, 5.5 -14.4, 13.2 -64.6, 93.3 -220.4mg kg -1 for Al, Ba, Cr, Cu, Fe, Ni and Pb respectively. The heavy metal concentration in the investigated areas followed the order Fe > Al > Zn > Pb > Ba > Cu > Cr > Ni. Principal Component Analysis (PCA) was carried out to ascertain the possible contributing factors towards the metal concentrations and thereby determine which metals have a common origin. PCA analysis indicated that three factors indicated source of mixed origin including mobile vehicle, street dust and natural sources.

“…The TC content of the house dust sample was 23.1%. In a study the concentration of floor dust in offices was 33% [15]. Considering a mass fraction of carbon in the organic matter the TC content is in a similar range.…”

-For the investigation of the distribution of heavy metals and other components in the various size fractions of house dust the dust sample was separated into size fractions by sieving and air classification. The analysis of the size fractions shows that the heavy metals and the other components are not uniformly distributed in the different size fractions. The highest total carbon (TC) concentrations were found in the size fractions with a mass median diameter of 18 to 95 µm, while in the coarser size fractions and in the finest size fraction the TC was lower. In contrast, for many heavy metals and other metals (e.g. Al, Fe, Mn, Ti, Ba, Sr, As, Cu, V) the maximum concentrations were found in the finest size fraction and with increasing size of the dust fractions the concentrations decreased. The distribution of Zn was different. In the four finest size fractions the concentration was nearly constant.
