The undercover investigation, which will be broadcast tonight at 8pm, focused on the levels of “ultra-fine particles” found in the air on and around cruise ships, from the fuel the ships’ engines burn. Dispatches used a P-Trak ultrafine particle counter to measure the ultra-fine particulates suspended in the air on board P&O Cruises’ ship Oceana. The device found 84,000 ultra-fine particulates per cubic centimetre on the deck downwind of, and directly next to, the Oceana’s funnels. That’s more than double the amount found at London’s Piccadilly Circus, where the number of ultra-fine particulates per cubic centimetre was 38,400. It’s called residual fuel, or heavy fuel oil.”From an environmental point of view, it’s bad because of the air pollution caused by the very high sulphur content.
