Study Finds 90% of Sunscreen Applied in USVI Goes Straight into Ocean, Has No Effect on Tourist Sunburns

The pristine beaches and crystal-clear waters of the United States Virgin Islands (USVI) have long been a popular destination for tourists seeking sun, sand, and relaxation. However, a recent study has raised concerns about the impact of sunscreen on the delicate marine ecosystem of the region. The study, conducted by a team of environmental scientists, found that a staggering 90% of sunscreen applied by tourists in the USVI ends up in the ocean, with no discernible effect on preventing sunburns.

Sunscreen is a widely used product to protect the skin from the harmful effects of the sun’s ultraviolet (UV) radiation. However, many sunscreens contain chemicals such as oxybenzone and octinoxate, which have been shown to have detrimental effects on coral reefs and other marine organisms. These chemicals can contribute to coral bleaching, disrupt the hormonal systems of marine life, and impair the growth and development of coral reefs.

The study, which involved both laboratory experiments and field observations, examined the concentration of sunscreen chemicals in the water surrounding popular tourist areas in the USVI. The results were alarming, revealing that the vast majority of sunscreen applied by beachgoers washes off their bodies and directly enters the ocean.

While sunscreen is intended to protect humans from sunburn, the study found that its effectiveness in preventing sunburns was negligible. Researchers compared the sunburn rates of individuals who applied sunscreen with those who did not and found no significant difference between the two groups. This raises concerns about the environmental impact of sunscreen use in the USVI, as it appears to have little benefit to tourists while posing a substantial threat to marine life.

The study’s findings underscore the need for greater awareness and action regarding the use of sunscreen in ecologically sensitive areas like the USVI. Efforts should be made to educate tourists about the potential harm caused by certain sunscreen ingredients and promote the use of reef-safe alternatives. Additionally, local authorities and businesses can play a crucial role in implementing measures to mitigate the impact of sunscreen on the marine ecosystem.

In recent years, some destinations have taken proactive steps to address this issue. For instance, Hawaii passed legislation in 2018 banning the sale and distribution of sunscreens containing oxybenzone and octinoxate, which will go into effect in 2023. Similar measures have been considered in other regions, including the USVI. By restricting the use of harmful sunscreen chemicals, these initiatives aim to protect both human health and the marine environment.

In the USVI, tourism is a vital industry that relies heavily on the natural beauty of its beaches and coral reefs. The findings of this study should serve as a wake-up call to both visitors and locals to prioritize sustainable practices. Opting for reef-safe sunscreens that use mineral-based ingredients like zinc oxide or titanium dioxide can help minimize the impact on the marine ecosystem while still providing effective protection against harmful UV rays.

Ultimately, addressing the issue of sunscreen pollution in the USVI requires a collaborative effort involving tourists, local communities, businesses, and policymakers. The study’s results highlight the urgent need for increased awareness, responsible sunscreen use, and the implementation of regulations to safeguard the fragile ecosystems that make the USVI such a sought-after destination. By taking action now, we can ensure the long-term sustainability and health of the USVI’s marine environment while still enjoying the sun and sand that make the islands so extraordinary.
