New research in Hong Kong has found that UV filters commonly used in sunscreen are polluting surrounding waters and could endanger human health, one of the city's leading universities said Thursday.

An "extensive amount" of seven common UV filter chemicals was found in Hong Kong seawater as well as in fish, shrimps and mussels on aqua-farms, scientists from Hong Kong Baptist University told reporters.

Effect - Contaminants - Food - Chain - Humans

"The effect of these contaminants passing along the food chain to humans and the long-term impact on human fertility cannot be neglected," said Dr. Kelvin Leung, who led the research.

Tests performed on zebrafish, which share a similar genetic structure to humans, showed the polluted water caused abnormalities and a higher mortality rate in the fish's embryos as the chemicals entered the food chain.

University - Study - Harm - Combination - Chemicals

The university described the study as a world-first in identifying the harm caused by a combination of polluting chemicals in sunscreen.

Researchers said they would conduct further tests to learn more about the effects of UV filters on the human body.
