Manila: Department of Environment and Natural Resources (DENR) Secretary Juan Miguel Cuna has issued a stern warning about the severe toxic risks posed by cyanide presence in the West Philippine Sea, highlighting its potentially devastating impact on marine ecosystems and human health.
According to Philippines News Agency, Cuna emphasized the dangers of cyanide during an interview at the launch of the DENR Permitting-On-Wheels in Binondo, Manila. He noted that cyanide is one of the most tightly regulated chemicals under government control due to its high toxicity. Cuna explained that the chemical control order (CCO) issued by the DENR-Environmental Management Bureau (EMB) mandates full monitoring of cyanide handling to prevent contamination and exposure.
Cuna's warning follows the confirmation by the National Security Council that bottles recovered by the Philippine Navy from foreign vessels near Ayungin Shoal tested positive for cyanide. This substance is known for causing rapid poisoning and long-term ecological damage. The DENR's Administrative Order 39, series of 1997, specifies that cyanide and its compounds are highly toxic to humans and aquatic life, even at low concentrations.
The order also highlights that cyanides are used in various industrial applications, including steel, plastics, and mining. However, they have also been misused in ways harmful to the environment, such as in the fishing industry. Authorities have warned that cyanide can kill fish and other marine organisms almost instantly, disrupt coral reef systems, and contaminate waters crucial for marine biodiversity and coastal livelihoods. Its presence poses a direct risk to personnel in the area, especially if exposure occurs through water or food sources.
Despite these alarming risks, Cuna mentioned that the government has yet to assess the full extent of environmental damage. He indicated that the Coast Guard and the Bureau of Fisheries and Aquatic Resources (BFAR) would be responsible for evaluating any impact on aquatic life.
Cuna assured that a whole-of-government approach is in place, with the Task Force on the West Philippine Sea coordinating to ensure a comprehensive response involving defense, maritime, and environmental authorities. The NSC had previously described the incident as a significant threat to marine ecosystems, food security, and the safety of Philippine forces in the area, as cyanide exposure could compromise both aquatic resources and human health.
Ayungin Shoal, where the contaminated materials were found, lies within the Philippines' exclusive economic zone, underscoring the importance of protecting its waters and resources as a national priority.
