Explained: What is plastic rain and how does it affect our health?

Did you know small particles of plastic are raining from the atmosphere? A mist of plastic descends from the sky every day but it is invisible to the naked eye, notes ScienceAlert. A new study has found that around 74 metric tons of microplastics fell from the sky in New Zealand’s Auckland city in 2020. The study published this week in Environmental Science & Technology says this amount of microplastic is equivalent to 3 million plastic bottles. Researchers believe the prevalence of plastic rain is undercounted globally, reported ScienceAlert. What is plastic rain and what did the study find? What have previous studies said about the existence of plastic in the air? How can it affect our health? Let’s take a closer look. Plastic rain Microplastics, very tiny pieces of plastic waste – less than 5 millimetres long, are raining from the sky. This microplastic emanates from packaging, clothing, vehicles, paint, worn car tyres and other sources. As per Wired, these small plastic particles are “flowing into the oceans via wastewater and tainting deep-sea ecosystems, and they’re even ejecting out of the water and blowing onto land in sea breezes”. Even though not many may not be aware of it, microplastics in the air are apparently “ubiquitous”. “If you go outside with a UV light, set at a wavelength of 400 nanometers, and shine it sideways you’ll see all kinds of plastic particles in the air fluoresce,” Deonie Allen, a researcher at EcoLab in the School of Agricultural and Life Sciences in Toulouse, France, told National Geographic in 2019. “It’s almost worse indoors. It’s all a bit terrifying”, she added. New study The study conducted by a team of scientists from the University of Auckland in New Zealand suggests that an average of around 5,000 pieces of microplastic fall on every square metre of Auckland’s urban rooftops any given day, reported ScienceAlert. The nine-week research was held in two sites in Auckland – on a university building’s rooftop and on the fence of a suburb. During the experiment, the researchers caught the residue of eight types of airborne plastics from both sites. “In Auckland, polyethylene — often used in packaging materials — was the most-detected substance, followed by polycarbonate, a type of plastic typically used in electrical and electronic applications,” Bloomberg reported citing the study. On the days when strong winds from the coast gushed through the city, there was a rise in microplastics collected using a funnel and jar contraption.

AFP (Representational Image)[/caption] “The production of airborne microplastics from breaking waves could be a key part of the global transport of microplastics,” chemist Joel Rindelaub from the University of Auckland was quoted as saying by ScienceAlert. “And it could help explain how some microplastics get into the atmosphere and are carried to remote places, like here in New Zealand”, Rindelaub stated.

The size of microplastics caught ranged between 10 and 50 micrometers in size.

While most of it was plastic fragments, only 3 per cent of particles were larger than 100 micrometres, ScienceAlert reported.

Another study, conducted in 2019 by scientists at Kings College London, said that an estimated average of 771 microplastic particles was found in central London. The rate of deposition of microplastic in London was much higher in London than in China’s Dongguan, China, Paris in France and Germany’s Hamburg, the study said. Earlier, scientists from the French national research institute CNRS reported the presence of microplastics in the air sampled 2,877 metres above sea level at the Pic du Midi Observatory in the French Pyrenees, as per The Guardian.  The study also highlighted sources of microplastic in the Mediterranean Sea and the Atlantic Ocean. Health effects Last year, a Portsmouth University study revealed that we inhale up to 7,000 airborne microplastic particles every day. [caption id=“attachment_11816791” align=“alignnone” width=“640”]microplastic There is a need for more research on the health effects of microplastic waste. AFP (Representational Image)[/caption] Experts said that this was “100 times higher than expected” and can pose a “potential health threat that could rank alongside asbestos or tobacco”, reported Daily Mail. In March this year, scientists announced microplastics were detected flowing through human veins, as per ScienceAlert.

Tiny fibers of plastic particles have also been found in lung cancer samples.

ScienceAlert said in April citing a study that it remains unknown how low levels of microplastics deep in our lungs are affecting our health. Stephanie Wright, a researcher at the Centre for Environment and Health at UK’s King’s College London, told National Geographic that people are coming across microplastics through food and air, but their health effects are yet to be discovered. Professor Anoop Chauhan, a respiratory specialist with Portsmouth Hospitals Trust, has warned of the dangers of breathing in microplastics as they “do not break down”. “Having these particles in your body can cause stress and changes in metabolism, it can affect immunity, the ability to fight infections, it can affect your reproductive capacity and potentially it could be carcinogenic – causing cancer”, he was quoted as saying by Daily Mail.  He further said that microplastic can potentially cause “inflammation and stress to cells”.
