Microplastics from the synthetic fibres common in fast fashion damage lung cells, study finds

Textiles and lungs

Microplastics from textiles may inhibit the lungs’ ability to repair damage caused by conditions such as Covid-19, scientists will warn today (24 February).

The research was carried out by scientists at Groningen University, The Netherlands Organization for Applied Scientific Research and Plymouth Marine Laboratory.  
The researchers found that both nylon and polyester negatively affected the growth and repair of airway tissue, and said the microfibres could make it more difficult for those with Covid-19 to mend their lungs.  
Speaking on The Plastic Health Channel, researchers will unveil new findings that revealed microfibres from textiles may be harming lung growth, development and repair. 
With humans exposed to microplastic fibres on a daily basis, scientists also warned of the potential health risks for those with developing lungs, such as children.

‘A virus damages the lungs so you need repair, and if your lungs are filled with fibres that are inhibiting this repair then you are in for another problem in addition to Covid-19.’

Microplastics and lungs

Researchers exposed airway and air sac organoids (miniature lungs) to nylon and polyester microfibres across 14 days to determine their impact, using fibres small enough to be inhaled. 
The resulting data suggested that microplastic textile fibre may especially harm developing airways or airways undergoing repair.
Researchers focused on polyester and nylon as they are the most abundant material in indoor settings, where humans spend the majority of their time.
The findings build upon research from Dr Fransien van Dijk and colleagues on the impact of microplastics on lungs, which was unveiled at the Plastic Health Summit in 2019. 

Plastic in rats’ foetal tissues

A second study, also set to be revealed on The Plastic Health Channel, found airborne nanoplastics are travelling from the lungs of pregnant rats to their foetus.
The study saw pregnant rats exposed to nanoplastics via inhalation before scientists measured the amount of plastic in both the maternal and foetal tissues.  
Nanoplastics were found in the pregnant rat’s lungs and heart, and they were also recorded in the foetus’ liver, lungs, heart, kidney and brain.  
Dr Phoebe Stapleton of Rutgers University, who conducted the study, warned the situation could also be the case for human lungs. 
She said: ‘We need to get a better handle on human exposure overall initially. We need to identify the chemicals in these nanoplastics.’
Both studies have raised serious concerns about the impact of microplastics entering the body, with experts on The Plastic Health Channel concerned about how they affect those suffering with Covid-19. 

Microfibres from clothes

The Plastic Health Channel is organised and produced by the Amsterdam-based Plastic Soup Foundation, with a view to taking an in-depth look into research and studies on the impact of plastic on human health.  
Speaking on The Plastic Health Channel, Laura Díaz Sánchez, Ocean Clean Wash campaigner, warned that microfibres from clothing are present in indoor settings as well as shedding during washing.  
She said: ‘More than half of the clothes we wear are made of materials like polyester. The problem with clothes made from materials such as polyester, with fibres which are short and spikey, is they get released much easier and then they are up in the air in this dust.’
