Densely populated cities rarely accommodate simple clotheslines for drying household washing. Instead, such cities are home to millions of electric tumble driers, whose exhausts to atmosphere are rich in fibrous microplastics detritus.

Clothes-washer lint filters are the first line of defence, both for ocean protection and atmosphere protection, but fresh microfibres are shredded from the textile in the following dryer process.

Commonly, condominium rules disallow drying of clothes on apartment balconies. This forces the installation of indoor drying appliances, of which the tumble dryer is the most common. A higher power than the building owners' associations could look to re-assess outdoor drying rules and line availability, hence minimise the need for tumble dryers.

However, London's Winter ambient temperatures render outdoor line/rack drying impossible in that season.

when growing up in PA my folks never had a Dryer, clothes were line dried all year. In the winter the clothes freeze dried but they did dry.

Let's all become Amish, using Solar clothes drying and eliminating dryer power requirements!

1. If 92% fibrous, and much is dryer-related, should we use finer screens on lint filters?

2. Microplastics are contaminants but not pollutants. Synthetic fibers (polypropylene, polyester and polyamides) are not toxic.

3. Does the study tell how much wool or cotton? Are nonplastic fibers less or more objectionable in the air, and if so, why?

4. The remaining 8% is from bags, packaging and other polystyrene? Bags are not polystyrene, some foam packaging is. Bags are mostly polyethylene; neither plastic will disintegrate to microparticles until after long exposure to sunlight.
