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.
