EPA’s nano-copper water treatment may pose health risks — Forensic Pathologist

A Forensic Pathologist, Professor Paul Poku Sampene Ossei, has raised red flags over the Environmental Protection Authority’s (EPA) use of ionic nano-copper technology to cleanse the Birim River.

The concerns come after the EPA launched a pilot water cleansing exercise on the Birim River at Adiukrom in the Asiakwa area to address pollution caused by illegal mining.

In a public notice ahead of the exercise which took place on Tuesday, February 24, the Authority said, “This initiative forms part of ongoing national efforts to combat the growing pollution of water bodies, particularly as a result of illegal mining activities.”

However, Prof Ossei said although copper is an essential element needed by the body, excessive accumulation can damage vital organs and even affect DNA.

Speaking on Accra-based JoyNews’ The Pulse on Tuesday, February 24, the Forensic Pathologist explained that nano-copper is primarily used to eliminate bacteria, viruses and fungi in water bodies.

He stressed, however, that the technology is not designed to remove heavy metals, which remain a major concern in rivers polluted by illegal mining.

“Copper is an essential element which humans actually need, but we need it in very, very small quantities, and we don’t need to exceed certain limits. Exceeding certain limits will bring a lot of problems to the human body and even to the environment,” he said.

The pathologist cautioned that when copper particles accumulate in the body over time, they can trigger oxidative stress; a condition where free radicals outnumber antioxidants.

According to him, this imbalance can damage DNA and lead to serious health complications, including harm to the liver, kidneys and central nervous system.

“When free radicals become more than antioxidants in the system, it can cause DNA damage. And when DNA damage is caused, it can attack a lot of things in the body,” he stated.

Meanwhile, EPA Executive Director, Professor Nana Ama Klutse, has indicated that the intervention will cost about $200,000 per kilometre of flowing river.
