They are the item that defined* the Covid-19 pandemic, and in many ways saved us from it, but they’ve also become a massive problem in their own right.
The number of face masks found in litter globally has skyrocketed* more than 80-fold because of the Covid-19 pandemic, a new study has found.
Citizen scientists in 11 countries, including Australia, used a litter-logging* app called Litterati to quantify the increase they have seen in discarded* personal protective equipment (PPE) since early 2020.
Besides an 84-times increase in dropped masks, the study also revealed gloves and wipes had more than doubled in litter volumes.
The problem was most widely reported in Britain, where PPE now accounts for more than 5 per cent of all litter.
Australia reported less overall PPE litter than most nations in the study, but more than New Zealand, Sweden and The Netherlands.
The authors of the study, which has been published in Nature Sustainability*, said the environmental impacts of PPE litter should be considered in future government pandemic responses, as the items damaged the environment in a number of ways: mask straps entangled wildlife both on land and at sea, the plastic elements broke down into harmful microplastics*, and their component* chemicals leached toxins into waterways.
Clean Up Australia chairman Pip Kiernan said the organisation would be using the sheer number of dropped masks as a call to action for the next Clean Up Australia Day on Sunday, March 6 next year.
“We don’t want the pandemic to have this huge environmental legacy*, and we can all take action,” she said.
So why are we seeing so many masks dropped on city footpaths and in parks? Mask-wearing suggests conscientiousness* and civic-mindedness*, which are not attributes* associated with people who litter.
But people could be reluctant to pick up someone else’s stray mask to put in the bin – even if they regularly collect other forms of litter when they see it – because of the direct link to Covid-19.
“A certain number are just being dropped in error,” Ms Kiernan said. “We all need to keep track and be super vigilant*.”
She said businesses could do their part by providing staff with reusable cloth masks, rather than handing out yet more disposable* masks.
“It’s not likely that mask wearing is going to go away any time soon,” she said. “When things settle with this pandemic, we’ll see more people wearing masks when they’ve got colds and flu, as we’ve seen in other parts of the world.”
Mask mandates* vary between states and territories in Australia. NSW wound back its mask rules on December 16, now requiring them only to be worn in high risk settings, such as on public transport and in healthcare facilities and airports. This brings NSW in line with Tasmania, South Australia and Western Australia.
Victoria was set to follow but decided to stick with its stricter rules, which require masks in shops as well as high-risk settings, until at least January 21 because of the new Omicron variant of the virus.
Chemist Warehouse director Mario Tascone said the chain was still seeing “strong sales” for both disposable and reusable masks.

1. Reducing mask waste
Work with a partner and brainstorm together three ways that you can think of to reduce the waste and littering being caused by disposable masks and PPE equipment. Be as creative as you can and you might even think of a new invention to help masks be more environmentally friendly. List your three ideas and share with the class.

A lot of people will pick up rubbish if they see it while walking by. But many aren’t as willing to pick up a used mask. How can we encourage people to a) not drop or litter with the masks and b) pick them up and put them in the bin when you see them flying around.
Think of a jingle or line to use in an advertising campaign to encourage the points above.
