Summary
Clothes dryers release significant microfibers, primarily cellulose and polyester, into the air. This study quantified household dryer emissions, estimating over 3,500 metric tons annually in the US.
Area of Science:
- Environmental Science
- Textile Science
- Consumer Science
Background:
- Microfiber contamination from laundry is an environmental concern.
- Data on microfiber release from household clothes dryers is limited.
Purpose of the Study:
- To quantify microfiber emissions from clothes dryers during normal household use.
- To identify the types of microfibers released and their sources.
Main Methods:
- Participatory scientists installed mesh filters on dryer vents for 3 weeks.
- Volunteers recorded drying activities via a mobile app.
- Accumulated material was analyzed for composition.
Main Results:
- Dryer lint primarily consisted of cotton and polyester.
- Cellulose and polyethylene terephthalate/polyester were the main microfibers found.
- Cellulosic textiles appeared to release more microfibers than synthetics.
- Estimated US dryer emissions: ~3,543.6 metric tons of microfibers annually.
Conclusions:
- Clothes dryers are a significant source of airborne cellulosic and synthetic microfibers.
- Reducing microfiber emissions from dryers is necessary.
- The study presents a replicable method for assessing dryer microfiber emissions.

01:21Drying Shrinkage
328
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
