House dust under a microscope Domestic dust on a ribbon A video on reducing dust exposure in the workplace. Dust control is the suppression of solid particles with diameters less than 500 micrometers (i.e. half a millimeter). Dust poses a health risk to children, [12] older people, and those with respiratory diseases. House dust can become ...
Dust bunnies (or dustbunnies) are small clumps of dust that form under furniture and in corners that are not cleaned regularly. [ 1 ] [ 2 ] They are made of hair, lint , flakes of dead skin, spider webs , dust, and sometimes light rubbish and debris and are held together by static electricity and felt -like entanglement.

The average life cycle for a house dust mite is 65–100 days. [9] A mated female house dust mite can live up to 70 days, laying 60 to 100 eggs in the last five weeks of her life. In a 10-week life span, a house dust mite will produce approximately 2,000 fecal particles and an even larger number of partially digested enzyme-covered dust ...
As such, the nature of occupational dust exposures can vary greatly by chemical composition, size, concentration, and toxicity to humans. Depending on the source, dust composition can include mineral dusts, heavy metals, respiratory sensitizers (chemicals that can cause allergic reactions such as asthma), chemical dusts, molds, spores, and more.
Cleaning agents or hard-surface cleaners are substances (usually liquids, powders, sprays, or granules) used to remove dirt, including dust, stains, foul odors, and clutter on surfaces. [1] Purposes of cleaning agents include health, beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others.
Dust samples can be analyzed using culture-based or culture-independent methods. Quantitative PCR is a DNA -based molecular method that can identify and quantify fungal species. The Environmental Relative Moldiness Index (ERMI) is a numerical that can be used in epidemiological studies to assess mold burdens of houses in the United States.
Not too surprisingly paper dust figured very highly in the organic fraction there, but more surprising was that the total organic fraction was only 33% by mass: 2/3 of Danish office dust is inorganic! (If this was a household dust study it would thoroughly debunk the myth, however one could quite reasonably claim that offices would have a lower ...
Household chemicals are non-food chemicals that are commonly found and used in and around the average household. They are a type of consumer goods , designed particularly to assist cleaning , house and yard maintenance, cooking, pest control and general hygiene purposes, often stored in the kitchen or garage.
