“…Participants were requested to abstain from cleaning floor surfaces for a period of 7 days before the scheduled house dust sampling. A composite indoor dust sample was collected in each home using the High Volume Small Surface Sampler (HVS3) vacuum sampler specified to capture 99% of all particles 0.5 µm and larger (Byrne 2000). The indoor dust was collected from different house compartments and connecting areas excluding potentially wet areas to protect the integrity of the sample.…”

“…However, the HSV3 sampler enables the user to control vacuum flow and pressure during operation, which makes it a very efficient dust sampler on worn carpets (Svendsen et al 2006). This vacuum sampler was developed according to the US EPA recommendations for the collection and analysis of Pb and pesticides in residential floor dust, and has been included for use in the ASTM D5438-94 (ASTM, 1994) method for the collection of carpet dust for chemical analysis (Byrne 2000, Svendsen et al 2006. Outdoor dust was collected from different areas outside the house with a small brush and a plastic shovel.…”

This study reports on data obtained from a pilot survey focusing on house dust and toenail metal (loids) concentrations in residents living in the industrial city of Estarreja. The study design hereby described aims at investigating relationships between human toenails and both copper and manganese levels in house dusts. A total of 21 households and 30 individuals were recruited for the pilot study: 19 households corresponding to 27 residents living near the industrial complex, forming the exposed group, plus 2 households and 3 residents from residential areas with no anticipated environmental contaminants that were used for comparison. Factorial analysis was used for source apportionment purposes. Investigation on the potential influence of environmental factors over copper and manganese levels in the toenails was carried out via questionnaire data and multiple correspondence analysis. The results show that copper concentrations are more elevated in the indoor dusts while manganese concentrations are more elevated in the outdoor dust samples. The geometrical relationships in the datasets suggest that the backyard soil is a probable source of manganese to the indoor dust. Copper and manganese contents in the toenail clippings are more elevated in children than in adults but the difference between the two age groups is not statistically significant (p> 0.05). Investigation of environmental factors influencing the exposurebiomarker association indicates a probable relationship between manganese contents in indoor dust and manganese levels in toenail clippings, a result that is partially supported by the bioaccessibility estimates.However, for copper no relationship was found between indoor dusts and the biomarkers of exposure.

Both epidemiological and experimental studies have demonstrated the crucial connection between air pollution exposure and skin disorders. The exact mechanisms by which air pollutants mediate skin damage remain largely unknown. Therefore, it is very necessary to investigate the mechanism of air pollution-induced skin damage and explore some potential protective and therapeutic methods. In this review, we focus on the qualitative and quantitative skin exposure assessment methodologies-a relatively new field of interdisciplinary research.

IntroductionSurfaces affect the indoor environment quality. By acting as sources and sinks for air contaminants they influence exposure of the room occupants. Moreover, surfaces and their contaminants affect the visual impression of the rooms. The degree to which the amount of surface dust affects the indoor environment needs to be assessed by quantitative measurements. This chapter begins with presenting a simple conceptual model including the compartments and transport processes that ultimately lead to exposure of room occupants by inhalation, ingestion, dermal uptake, or by visual perception. The model is then used to structure the presentation of measurement principles. Sources of variability in surface dust concentrations are listed that need to be known in order to design cost-effective sampling strategies. Finally, specific sampling methods are described. It has been the intention in this chapter to present key elements of surface dust sampling, which the investigator can use to design a sampling protocol for a particular task. For details of the quoted methods, the reader is referred to the original papers. Aspects of sampling that are specific for microorganisms, such as use of agar contact plates, are not covered.Surface contaminants may consist of dirt, loose dust, strongly adhering particles, and "greasy" matter, as well as adsorbed vapors. For simplicity, this entity will be termed dust, unless specified otherwise. 2.3.2 The ScenarioThe contribution of surface dust to the indoor environment quality can be viewed from different angles, defined by the question asked. Surface dust can be viewed, e.g., as:Reflecting what has been in the air averaged over the time period since the surface was cleaned. A secondary source of airborne particles if agitated. Indicating efficiency of last cleaning and recontamination rate. 82 2.3
