When Sunscreen Meets Plastic: A Newly Discovered Threat to Marine Ecosystems
AUSTRALIA, JUL 8 – Australia's regulator calls for tighter sunscreen ingredient limits after consumer tests showed some brands failed to meet SPF 50 claims, amid global safety concerns.
- Researchers at the University of Stirling, under the guidance of Dr. Sabine Matallana-Surget, investigated the impact of the sunscreen ingredient EHMC on the formation of biofilms associated with marine plastic debris.
- The study examined co-pollution where UV filters like EHMC bind to plastics, altering microbial communities and slowing plastic degradation in oceans.
- Researchers found EHMC increased the OprF protein in Pseudomonas, stabilizing harmful biofilms, and shifted microbial metabolism toward anaerobic respiration, raising ecological risks.
- Dr. Matallana-Surget stated, "These changes matter," and urged policymakers to address sunscreen pollution due to its threats to ecosystem stability and human health.
- The findings imply that sunscreen pollution may prolong plastic persistence in marine environments, highlighting a need for reformulation efforts and increased awareness to protect coasts.
