Abstract

Ballast water is essential for ship stability during cargo operations and voyage, but its discharge can introduce invasive aquatic species to new environments. To mitigate this risk, ballast water is commonly treated with oxidants such as hypochlorite. The Ballast Water Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP-BWWG) evaluates and recommends ballas…
