China's Ministry of Ecology and Environment on Friday released the 2025 survey and assessment report on the ecological environment of the waters around China's Huangyan Dao in the South China Sea, saying that the island maintains excellent marine environment quality.

The report notes that seawater and marine sediments both met Class I standards, while concentrations of pollutants such as heavy metals and petroleum hydrocarbons in fish samples remain below evaluation thresholds. No cyanide has been detected in seawater, sediments or fish samples.
