The chemicals found in sunscreens are becoming an increasing presence in our ocean. But there are still significant gaps in our understanding of how they might affect marine ecosystems, according to a new study.
Sunscreens contain chemical compounds that filter out the sun's ultraviolet (UV) rays. UV filters are also added to personal care products (e.g. shampoos, moisturisers, lipsticks, shower gels) and various other commercial products including plastics, rubber, paint and cement, to enhance light resistance and prevent photodegradation.
As a result of modern lifestyles, with UV filters vital for human health and extending the lifespan of materials, they are emerging as a major environmental concern due to their widespread use and worldwide distribution.
With global sunscreen sales projected to reach $13.64 billion by 2026 and an estimated 6,000-14,000 tonnes of UV filters released annually into coral reef zones alone, researchers emphasize the urgent need for more comprehensive studies on their environmental impact.
