Costa, a unit of the world's biggest cruise operator, the Miami-based Carnival Corp., also said it would reimburse passengers the full costs of their cruise, travel expenses and any medical expenses sustained after the grounding. But Roberto Corbella, who represented Costa in the negotiations, said the deal offered Friday provides passengers with quick, "generous," and certain restitution that consumer groups estimate could amount to some euro14,000 per passenger including the reimbursements. "The big advantage that they have is an immediate response, no legal expenses, and they can put this whole thing behind them," he told The Associated Press. Angry passenger Herbert Greszuk, a 62-year-old German who left behind everything he had with him, including his tuxedo, camera, jewelry, and even his dentures, told the AP before the compensation was announced that it was an issue of accountability. Something like this must not be allowed to happen again. So many people died; it's simply inexcusable," he said. Italy's civil protection office on Friday released a list of some of the other possibly toxic substances aboard the cruise liner amid concerns of possible environmental pollution. They include 50 liters of insecticide and 41 cubic meters of lubricants, among other things. But so far, even though there has been some film detected in the waters around the ship, tests on the waters indicate nothing outside the norm, according to Tuscany's regional environment agency.
