The chemical compounds present in sunscreens are generating growing environmental concern due to their impact on the oceans and marine life. Recent research warns that these products can accumulate in water and affect both ecosystems and human health.
A study published in the journal Marine Pollution Bulletin by scientists from the Marine Laboratory at the University of Plymouth revealed that UV filters can enter the ocean directly, through recreational activities in the water, or indirectly, through laundry, showers, or liquid waste disposal. It is estimated that between 6,000 and 14,000 tons of UV filters reach the oceans each year, only in coral reef areas.
The most concerning substances are benzophenones, particularly oxybenzone, which was identified by the European Chemicals Agency as a compound with the potential to disrupt the hormonal balance of marine organisms. However, there are still limitations in studies regarding its long-term impact.
Researchers detected the presence of these chemicals in marine ecosystems worldwide, even in remote regions such as Antarctica and the Arctic. Dr. Frances Hopkins, co-author of the study, pointed out that the oceans are already facing multiple stressors, such as global warming and acidification, making it even more urgent to understand the impact of chemical pollution.
Moreover, these compounds can bioaccumulate in marine fauna, increasing the risk of entering the human food chain. It is estimated that 4.3 billion people rely on fish as their main source of protein, reinforcing the need to study the possible effects of this contamination on public health.
Measures and Calls to Action
The scientific community has warned about the lack of long-term studies and proposes urgent measures, such as evaluating the chronic exposure of marine species to these compounds and researching new, less harmful formulas.
“It is essential to understand the impact of these substances and apply the precautionary principle before introducing new chemicals into the marine ecosystem,” said Dr. Mahasweta Saha, an expert in marine ecology.
Faced with this issue, the use of eco-friendly sunscreens is promoted with mineral filters and the development of stricter regulations to reduce pollution in the oceans.
What are eco-friendly sunscreens like and what are their benefits?
Eco-friendly sunscreens are made with natural and mineral ingredients, and are less harmful to the environment. Certified organic sunscreens also prohibit the use of petrochemical active ingredients that are generally considered harmful to the environment.
Benefits
- Protect the skin: They offer protection against UVA and UVB rays, sunburn, premature aging, and skin damage.
- Are eco-friendly: They do not contain harmful artificial ingredients and are usually packaged in recyclable or biodegradable containers.
- Are less likely to irritate the skin: They are free of fragrances and synthetic preservatives, making them ideal for people with sensitive skin or allergies.
- Are less harmful to marine life: Their biodegradable ingredients are less harmful to coral reefs and marine life.
