Settleable Dust and Bioburden in Portuguese Dwellings

Dust and endotoxin in laying hen dwellings

Only healthy laying hens are capable of producing an average of 280 eggs in 1 year of exploitation. Production of consume eggs takes place in intensive housing systems where the laying hens are still mainly kept in cages under controlled conditions. Technical infrastructure and hygiene quality do not guarantee a production atmosphere completely free from pollutants, including potential patholog...

Variability of house dust mite allergen exposure in dwellings.

The variability of repeated house dust mite (HDM) allergen determinations at the same site within 3-24 months was evaluated on previously collected samples. Between two and four repeated measurements of Der p 1, a major allergen of Dermatophagoides pteronyssinus and Der f 1, a major allergen of D. farinae, on 46 carpets and 31 mattresses were analyzed. In 90% of carpets and mattresses, HDM alle...

Concentration and determinants of molds and allergens in indoor air and house dust of French dwellings.

Molds and allergens are common indoor biocontaminants. The aims of this study were to assess the concentrations of common molds in indoor air and floor dust and the concentrations of house dust mite, cat and dog allergens in mattress dust in French dwellings, and to assess predictors of these concentrations. A sample of 150 houses in Brittany (western France) was investigated. Airborne Cladospo...
