A new study has found sunscreen chemicals in Mediterranean seagrass. UV filters absorbed by Posidonia oceanica could cause long-term damage to local ecosystems.
A new study suggests that sunscreen could be affecting our oceans.
Chemicals from popular sunscreen lotion brands have been found ‘accumulating’ in Mediterranean seagrass. Scientists discovered ultraviolet filters in the stems of a certain type of seagrass known as Posidonia oceanica, found on the coast of Mallorca.
Researchers believe the cause is likely to be tourism wastage in the local area, as samples included varying concentrations of sunscreen components. Oxybenzone, avobenzone 4-methyl, benzylidene camphor, benzophenone-4, and methyl parabens were all discovered.
The actual effects are unknown as of yet. Scientists do not have any indication on how severe the impact could be, though they do remain concerned.
In a statement, the study’s co-author Prof Nona Agawin said that ‘we will have a problem’ if sunscreen is found to affect the photosynthesis of seagrass. ‘Seagrasses play an important ecological role in the Mediterranean coasts.’
We’ve known for a while that using sunscreen can cause environmental problems – and not just for seagrass.
Certain UV-filtering sunscreen chemicals can damage fish, dolphins, and turtles. Reproductive systems can become disrupted, ultimately harming the development of young sea life.
The conclusion from the study is that, ultimately, more research needs to be done to understand how sunscreens and UV chemicals can affect seagrass meadows.
Agawin added that ‘if we find which sunscreen components are harmful, then we should regulate and provide alternatives’.
So, the news of sunscreen causing problems in our seas may tempt you to avoid using the stuff altogether. However, skin is still susceptible to damaging sunrays – so it’s best to continue protecting yourself if you do decide to head out on holiday.
There are various brands available that are oxybenzone and octinoxate free. Rolling Stone recommends Stream2Sea Sport, Supergoop!, Badger Clear Zinc, and a bunch more sustainable options. Check out the full list here.
Avoiding some holiday destinations could help to keep pollution levels down too, mind. A different research piece from 2020 noted that 267 million tourists visit the Mediterranean Sea every year and warns of the potential harm that accumulating sunscreen chemicals could cause.
We could be seeing sunscreen phased out from our shops in the near future, with eco-friendly alternatives providing as substitute.

Less 20-somethings are getting married today than ever. As Gen Z ditches wedding rings, it begs the question: what has changed?
There’s little I love more than the sweet sound of an orchestra playing a doting love song, as a couple makes it down the aisle, ready to make the ultimate commitment and say: ‘I do’. Yet nowadays, it seems like my generation is more inclined to say ‘I don't’...
Companies in the Global North are increasingly purchasing carbon credits to offset their emissions, while projects across Africa are encouraging farmers to adopt climate friendly practices that can generate those credits.
The process is theoretically simple. Farmers plant trees or adopt other practices that help to sequester carbon dioxide directly from the atmosphere. This is then measured and sold to companies as credits to help them offset their own impact...
Staff and students at the University of Kent were devastated by a fatal outbreak of meningitis last week, which left two people dead and more than 10 hospitalised.
The incident has thrown a community into chaos, as students begin to worry about those they’ve come into contact with and University staff try to manage the outbreak. Hundreds of young people have since begun queuing for antibiotics, while in-person exams...
A recent move by the UK government may alter the educational routes of thousands of young people in the Global South, especially those from areas experiencing conflict.
Recently, the Home Secretary, Shabana Mahmood, announced a plan by the British government to stop issuing study visas to students from various countries in the Global South. These include Cameroon, Sudan, Myanmar, and Afghanistan. If everything goes as planned, the policy...
