It’s nursing season in Europe’s biggest marine sanctuary and schools of whales have brought their young to Italian shores — but environmentalists warn they are at risk from toxins leaked by the wrecked Costa Concordia cruise ship.
The luxury liner crashed off the Tuscan island of Giglio in 2012, killing 32 people and sparking an unprecedented salvage operation set to conclude this month with the floated wreck being towed more than 200 nautical miles north to the port of Genoa to be scrapped.
Greenpeace and Italy’s main environmental group, Legambiente, have voiced concerns that the hull of the damaged ship may not withstand the stress of the four-day journey and could rupture, spilling a noxious brew of heavy metals, oils, plastics and sewage chemicals into the sea.
What is more likely is that it will remain intact but shed debris and leak some of the estimated 263,000 cubic metres (over 69 million gallons) of polluted water inside it, or the 100 tonnes or so of fuel left behind when the tanks were emptied.
“The Concordia will cross a protected area home to dolphins and sperm whales, as well as fin whales who bring their young here at this time of year to feed in the rich waters off Genoa,” Greenpeace’s Giorgia Monti told AFP.
“We are very worried about the effect spills or debris could have on them,” she said, with possible flotsam such as cables, varnished furniture or electrical appliances releasing substances such as phthalates and alkylphenols, which harm the reproductive system in mammals.
Costa Crociere, the ship’s owner and Europe’s biggest cruise operator, insists the amount of leakage will be comparable to that discharged by any vessel crossing the area — one of the most trafficked in the Mediterranean.Ten boats will accompany the Concordia up the Corsica Channel alongside teams tasked with collecting any debris, testing the water for toxins and spotting any approaching dolphins or whales to prevent any collisions.
Emergency equipment to be used in case of toxic leaks from the ship will include 800 metres of oil booms — a kind of temporary floating barrier that helps to contain a spill — and infrared sensors to detect oil on water at night.
