Russian scientists have developed secret ship hull protection from shellfish
Compounds based on copper are usually used to prevent marine vessels hulls from being overgrown with algae and small invertebrates. The problem is that these compounds are toxic. Scientists at St. Petersburg State University have found environmentally friendly compounds that can be included in protective coatings.
The experts tested the compounds in the open environment, namely in the White Sea and the South China Sea, and now they are testing it on starfish and spores of sea brown seaweed (laminaria, commonly known as «kelp») at the resource centre «Observatory of Ecological Safety» of St. Petersburg State University.
