英国第四频道《深入报道》节目调查发现,邮轮甲板上的空气污染程度超过了世界上污染最严重的城市。
The undercover investigation on Britain's biggest crew operator P& O Cruises aimed to find out how clean the air holidaymakers breathe when on a ship is.
It focused on the levels of" ultra-fine particles" found in the air and around the cruise ship and emitted from the fuel the ships ' engines burn.
But while passengers hope to escape the dirty air of cities for some fresh sea air, the investigation found cruise ships are having a negative impact on the environment. One cruise ship can emit as much particulate 2 matter as a million cars in a day.
The device found that the air on the deck downwind of, and directly next to the ship's funnels 3, had 84,000 ultra-fine particulates 4 per cubic centimetre.
Directly next to the funnels on the deck, the numbers rocketed to 144,000 with a peak at 226,000.
This is more than double the average found in central London's Piccadilly Circus, where using the same device, the Dispatches team recorded 38,400 ultra-fine particulates per cubic centimetre.
While the deck is popular with sun-bathers, passengers are likely to be breathing some of these particulates, which are harmful for health and the environment.
